HeroX's Open Call for Startups

Grant Overview

Quick, honest summary: HeroX’s Open Call for Startups is a free, rolling platform where startups create profiles so enterprise partners and challenge sponsors can discover them.

If you found this page searching for “HeroX startup grant,” let’s clear up what this actually is right away. HeroX’s Open Call isn’t a traditional grant with prize money and application deadlines. It’s a free, ongoing platform where startups create profiles to potentially connect with organizations seeking innovative solutions. Think of it as a specialized directory that puts your startup in front of corporate innovation teams, government agencies, and enterprises looking for technology partners. For B2B startups with working prototypes ready for pilot programs, this could open doors to partnerships worth far more than small grant checks. But if you need immediate cash to make payroll or fund development, traditional startup grants will serve you better right now.

Focus Areas

Startup visibility Corporate partnerships Innovation matchmaking B2B connections

The platform was built by the same people who created the XPRIZE Foundation. They have run innovation challenges for NASA and major enterprises for over a decade. That is real credibility. But here is what most people get wrong: they show up looking for guaranteed funding and find a matchmaking platform instead.

Quick Eligibility Check: Is HeroX Right for Your Startup Stage?

Before diving into the details, use this tool to assess whether HeroX’s platform matches where your startup is right now. It evaluates your development stage, customer focus, and immediate needs to determine if this exposure opportunity makes strategic sense or if you should prioritize traditional funding sources instead.

If the tool shows strong fit, the application process below walks through exactly what to prepare. If you’re not quite ready or need cash immediately, the alternative grants section recommends proven funding sources with actual monetary awards. And if you’re unsure how to position your technology or intellectual property for maximum visibility, Grantaura’s experts can help structure your profile to attract the right corporate partners.

Understanding What HeroX Actually Offers Startups

HeroX built its reputation hosting innovation challenges for organizations like NASA, Lockheed Martin, and government agencies. Those competitions offer real prize money for solving specific problems. The Open Call for Startups works differently. Instead of competing for awards, you’re building a persistent presence in their ecosystem.

Here’s how the platform functions. Organizations come to HeroX when they need solutions to problems. Sometimes they launch public challenges with prize pools. Other times they browse the startup directory looking for existing technologies before creating a formal challenge. By having an active profile, you position your startup for both scenarios.

The value proposition depends entirely on your business model. If you’re building B2B technology that enterprises could pilot or license, corporate visibility matters more than a $5,000 grant. But if you’re pre-revenue and need capital to finish building your product, direct funding from sources like Nehemiah Davis Greatness Grant ($2,500 quarterly) or Breva Thrive Grant ($5,000) provides more immediate value.

The Technology Readiness Level Framework

HeroX uses NASA’s Technology Readiness Level (TRL) system to categorize innovations. Understanding where your startup falls on this scale helps you position your profile effectively.

You don’t need to be at TRL 9 to participate. All stages are welcome. But knowing your TRL helps corporate partners quickly assess whether your timing matches their needs. A company looking for an immediate pilot program will focus on TRL 5-7 startups rather than early concepts.

Who Benefits Most From Platform Visibility

The strategic fit for HeroX’s Open Call varies dramatically based on your startup’s current situation and needs.

Strong Fit Scenarios

B2B technology startups with working prototypes face a consistent challenge getting in front of enterprise decision-makers. Cold outreach gets ignored. Warm introductions are hard to find. HeroX provides a channel where corporate innovation teams actively search for solutions. If your startup addresses problems in aerospace, defense, energy, sustainability, or government operations, the platform’s NASA and Fortune 500 connections create relevant visibility.

Deeptech companies needing more than money benefit here too. If what you actually need is a partner with testing facilities, regulatory expertise, or specialized infrastructure, exposure to corporate R&D teams matters more than grant funding. A co-development partnership with an established company provides resources and credibility that cash alone can’t replicate.

Startups already pursuing multiple funding sources can add HeroX as a portfolio approach. Since there’s no deadline and the profile takes under an hour to complete, it functions as a “set and maintain” channel that runs parallel to active grant applications.

Poor Fit Scenarios

Consumer-focused B2C startups get limited value from corporate matchmaking. Organizations browsing HeroX seek solutions to their operational problems, not products for their customers. If you’re building a consumer app or retail brand, focus on customer acquisition and revenue generation instead.

Pre-revenue startups still building toward a prototype should prioritize development funding. If you’re 6-12 months from having something to demonstrate, cash grants like Emergent Ventures or state innovation programs provide the capital you need to reach that milestone first.

Anyone expecting guaranteed outcomes or structured support should look elsewhere. Unlike accelerators with defined curricula and mentor matching, HeroX offers platform access without promised results. The value is speculative based on whether organizations actively use the directory to find startups.

Application Process and Profile Creation

Setting up your HeroX presence is straightforward but requires thoughtful preparation to maximize visibility.

What You’ll Need Before Starting

Step-by-Step Submission Process

After submission, your profile becomes searchable within HeroX’s platform. Organizations can browse by industry, technology category, or TRL level. The platform documentation states their team may reach out for additional information or to discuss potential opportunities, though there’s no defined timeline for when this might happen.

Optimizing Your Profile for Corporate Discovery

Q: How long does the application take to complete?
A: Expect 30-45 minutes if you have materials prepared. Account creation is about 5 minutes, the submission form takes 20-30 minutes, and reviewing privacy settings plus uploading optional materials adds another 5-10 minutes.

Q: Can I update my profile after submitting?
A: Yes. You can update your startup profile anytime to reflect new achievements, partnerships, or developments. Regular updates may help maintain visibility in platform searches.

Q: Is there any application fee or cost to join?
A: No. Creating an account and submitting your startup profile is completely free. There are no hidden charges for maintaining your presence on the platform.

Submission Tips

1. Start with one simple sentence: what problem you solve and who benefits.
2. Prioritize impact metrics over raw technical detail (redact sensitive numbers if needed).
3. State partnership interests clearly: pilot, licensing, or joint development.
4. Keep bios short: role and relevant experience matter more than long CVs.

The Distinction Between Open Call and Prize Challenges

Understanding how HeroX’s startup platform relates to their traditional challenge business prevents confusion about what you’re actually joining.

HeroX’s core business involves hosting time-bound innovation challenges. An organization defines a specific problem, sets a prize amount (sometimes exceeding $1 million), and opens submissions for a limited period. Winners receive the prize money. These challenges are competitive events with clear start and end dates.

The Open Call for Startups is fundamentally different. It’s an ongoing directory where your profile remains active indefinitely. You’re not competing against other startups for a fixed prize pool. Instead, you’re making yourself discoverable to organizations that might want to partner with you independently.

Some startups do both. They maintain an Open Call profile while also competing in specific challenges when relevant problems get posted. The profile serves as a permanent presence while challenges offer opportunities for direct prize money.

Q: Does having an Open Call profile give me any advantage in HeroX challenges?
A: Not explicitly stated. Challenges typically have their own submission processes. However, organizations browsing startup profiles might invite you to participate in upcoming challenges before they go public.

Intellectual Property and Privacy Considerations

Sharing technology information on any public platform raises legitimate concerns about intellectual property protection.

HeroX gives you control over what information becomes public versus what stays private. During profile creation, you explicitly choose which sections to make searchable. Technical details, proprietary information, and sensitive business data can remain confidential while still allowing you to showcase general capabilities.

For deep-tech startups with patented innovations, consider what level of detail to share publicly. You want enough information to attract interest but not so much that you’re giving away competitive advantages. Focus on the problem you solve and general approach rather than specific implementation details.

Organizations that contact you through HeroX will typically require confidentiality agreements before detailed technical discussions. The initial profile serves as an introduction, not a comprehensive technical disclosure.

Q: What happens to my data if I decide to leave the platform?
A: Check HeroX’s terms of service for specific data retention policies. Generally, you should be able to deactivate or remove your profile, though you’ll want confirmation about whether submitted information gets permanently deleted.

Q: Can competitors see my HeroX profile?
A: If you make your profile public, anyone can view it including competitors. This is why careful consideration of what to share publicly versus keep private matters. Balance visibility to potential partners against competitive intelligence concerns.

Combining HeroX With Active Grant Applications

The smartest funding strategy treats HeroX as one channel in a diversified approach rather than your only focus.

Create your HeroX profile during one focused session, then let it work passively in the background while you actively pursue time-sensitive opportunities. Apply to monthly grants like Sky’s the Limit Friends & Family Fund ($2,500 monthly for underrepresented entrepreneurs) or quarterly programs like Secretsos Small Business Grant ($2,500 quarterly). These provide actual capital while your HeroX profile generates potential leads.

For technology startups specifically, state innovation programs often provide substantial funding. Maine Technology Institute offers seed grants for technology commercialization. InnovateMass provides up to $350,000 for Massachusetts clean energy technology. These complement platform exposure with real development funding.

If you’re seeking both cash and networking, Fast Pitch Competition awards $25,000 grants plus investor networks for women-led startups. This delivers guaranteed funding if you win while building the relationship benefits that HeroX promises but doesn’t guarantee.

Portfolio Timeline Strategy

Q: Should I do HeroX instead of applying to grants?
A: No. Do both strategically. HeroX takes minimal time to set up and requires little ongoing effort. Traditional grants take more work per application but provide guaranteed funding if awarded. Pursue active grants for immediate needs while maintaining HeroX profile for longer-term partnership possibilities.

Realistic Expectations and Limitations

Honest assessment requires acknowledging what remains unknown about this platform’s effectiveness.

HeroX’s Open Call launched in January 2025, making it relatively new. Without published success metrics, partnership examples, or case studies, we can’t verify how many startups have actually connected with organizations through the platform. The absence of this data after over a year of operation is notable.

The platform’s value depends entirely on organizational adoption. If few companies actively browse startup profiles, your time investment generates zero return. We have no visibility into how many organizations use the directory, how frequently they search, or what percentage of startups receive inquiries.

Startup directories and databases often launch with enthusiasm then see declining engagement as organizations stick with established channels like investor networks or warm introductions. HeroX’s advantage is their existing challenge business, which theoretically provides a built-in audience of innovation-seeking organizations. Whether those organizations also use the startup directory remains an open question.

Q: Are there any success stories or testimonials from startups?
A: Not publicly available as of early 2026. The program launched in January 2025 but hasn’t published case studies or verifiable examples of partnerships formed through the platform.

Q: How do I know if my profile is actually being viewed?
A: Check if HeroX provides analytics showing profile views or search appearances. If this data isn’t available in your dashboard, you’re essentially operating blind on whether the platform generates any visibility.

When to Seek Expert Help With Your Submission

Certain situations benefit from professional guidance rather than going it alone.

If you’re unsure how to position your technology or translate technical capabilities into business value propositions, that’s a sign to get help. Organizations browsing HeroX aren’t looking for academic papers. They want to quickly understand what problem you solve and why your approach works.

Startups with complex intellectual property considerations should ensure they’re not inadvertently disclosing proprietary information. If you’re uncertain what’s safe to share publicly versus what needs protection, consultation with both IP counsel and grants experts helps avoid costly mistakes.

For founders juggling product development, fundraising, and customer acquisition, outsourcing profile optimization saves time. Grantaura’s team helps startups structure their narratives for institutional matchmaking, ensuring your Technology Readiness Level is clear and your partnership interests are well-articulated.

Common Questions About HeroX’s Open Call

Q: What if my startup is still in the idea stage?
A: You can join at any TRL level. However, organizations typically seek startups with at least working prototypes (TRL 4+) for pilot programs. Early concepts may get less interest but can still participate.

Q: Does HeroX take equity in participating startups?
A: No. HeroX operates on a challenge and platform model, not an accelerator model. They don’t take ownership stakes in startups using their platform.

Q: How private is my information?
A: You control visibility settings during profile creation. Choose which sections to make public and which to keep private. Review HeroX’s privacy policy for details on data handling.

Q: What if something in my profile isn’t clear or seems confusing?
A: Don’t guess on critical details like eligibility requirements or technology categorization. If official documentation leaves you uncertain, reach out to Grantaura’s experts. We can clarify ambiguous requirements, help you assess strategic fit, and even handle the entire submission on your behalf.

Q: Can international startups outside the US participate?
A: Yes. Geographic eligibility is global. Startups from any country can create profiles. However, check whether specific organizations browsing the platform have geographic preferences for partnerships.

Q: How often should I update my profile?
A: Quarterly updates keep your information current and may improve algorithmic visibility. Update whenever you reach new milestones like completing pilots, securing customers, or advancing your TRL level.

Key Terms for Understanding HeroX’s Ecosystem

• Technology Readiness Level (TRL): A 1-9 scale developed by NASA measuring how close a technology is to real-world deployment. TRL 1-3 represents basic research. TRL 4-6 covers lab and field validation. TRL 7-9 indicates operational systems. HeroX uses this framework to categorize startups and match them with appropriate organizational needs.
• Open Innovation: Corporate strategy of seeking external solutions rather than developing everything internally. Companies practicing open innovation actively look for startup partnerships, which is why platforms like HeroX exist. Understanding this mindset helps you position your startup as a solution to their innovation challenges.
• B2B (Business-to-Business): Companies selling products or services to other organizations rather than individual consumers. HeroX’s platform primarily benefits B2B startups since browsing organizations seek operational solutions, not consumer products. If your startup sells to enterprises, this platform is relevant.
• Pilot Program: Small-scale test of a product or service in a real-world environment before full deployment. Enterprise customers typically run pilots to validate solutions before committing larger budgets. Landing pilot programs through HeroX can provide both revenue and valuable case studies.
• Corporate Innovation Team: Internal groups at large companies tasked with finding new technologies and partnerships. These teams often browse platforms like HeroX searching for startup solutions to organizational problems. They’re your target audience on the platform.
• Crowdsourcing Platform: System that gathers solutions from large groups of external contributors. HeroX’s core business is crowdsourced innovation challenges. The startup directory complements this by providing ongoing visibility beyond time-limited competitions.
• Non-Dilutive Funding: Capital that doesn’t require giving up equity or ownership in your company. Prize challenges and grants are non-dilutive. VC investments and accelerators typically are dilutive (they take equity). Understanding this distinction helps you evaluate different funding sources.
• Intellectual Property (IP): Legal rights to inventions, designs, brands, and creative works. When joining platforms, startups must carefully consider what IP to disclose publicly. HeroX allows privacy controls but you’re still sharing some information in a searchable format.
• Value Proposition: The specific benefit your product provides and why customers should choose you over alternatives. Strong HeroX profiles clearly articulate value propositions addressing organizational pain points rather than just listing technical features.
• Innovation Challenge: Time-limited competition where organizations post specific problems and offer prizes for solutions. This is HeroX’s traditional business model. The Open Call complements challenges by providing permanent startup visibility rather than one-time competitions.
• Matchmaking Algorithm: Software that pairs startups with relevant organizational opportunities based on keywords, industry, technology category, and TRL level. Understanding how these algorithms work helps you optimize your profile for discovery.
• Strategic Partnership: Ongoing collaborative relationship between organizations pursuing mutual objectives. Unlike transactional customer relationships, strategic partnerships involve sustained cooperation that can include co-development, joint marketing, or shared distribution. These relationships often start with pilot programs.
• Deeptech: Startups building advanced scientific or engineering innovations requiring significant R&D. Common in aerospace, defense, materials science, and emerging technologies. Deeptech companies often need more than money, including access to specialized facilities and expertise that corporate partnerships provide.
• Market-Ready Solution: Product or service developed to the point where it can be sold and delivered without significant additional development. Organizations browsing HeroX often prefer market-ready solutions (TRL 7+) they can deploy quickly rather than earlier-stage concepts.
• Co-Development Agreement: Partnership where two organizations collaborate on developing technology or products. Unlike one party paying for a finished product, co-development involves shared effort and often shared IP rights. Common structure for deeptech startups partnering with corporations.
• Prototype Validation: Process of testing whether a working model performs as intended in relevant conditions. Moving from concept (TRL 1-3) to validated prototype (TRL 4-6) is critical for attracting pilot program interest through platforms like HeroX.
• Enterprise Customer: Large organization (typically 1000+ employees) that becomes a paying customer. Enterprise deals involve longer sales cycles but provide larger contract values. Platform exposure that leads to enterprise customers can be more valuable than small grants for growth-stage startups.
• Innovation Ecosystem: Network of organizations, startups, researchers, and supporters working in related areas. HeroX’s ecosystem includes challenge sponsors like NASA, government agencies, and Fortune 500 companies. Joining gives you access to this established network.
• Profile Optimization: Strategic approach to creating platform profiles that maximize discovery and interest. Includes keyword selection, clear value propositions, appropriate TRL categorization, and compelling descriptions that convert browsers into contacts.
• Technology Transfer: Process of moving innovations from research environments into commercial applications. Often involves partnerships between academic institutions, startups, and corporations. HeroX facilitates technology transfer by connecting innovators with organizations seeking solutions.
