Search official grant portals and program pages first, then filter every result by geography, applicant type, technology stage, fundable activity, deadline, and evidence readiness. Most funders do not label calls as "deeptech grants". You will find better opportunities by searching broader terms such as startup grants, SBIR/STTR, innovation funding, R&D grants, EIC Accelerator, Innovate UK grants, Eurostars funding, and non-dilutive funding.
A grant search fails when it starts as a hunt for free money. For a deeptech founder, the job is narrower: find calls where your company, geography, technology maturity, project plan, and evidence are already close to the funder's rules. That is why this guide focuses on a search routine, not a generic list of funding links.
If you already have a grant in mind and need to check whether you are eligible, start with the grant eligibility checklist. If you are still building the shortlist, use this article first.
Short answer
A useful grant search starts broad and gets narrow quickly. Use official portals to capture the market, then reject bad-fit calls before you spend time reading guidance notes or drafting an application.
| Search layer | What to do | Why it matters |
|---|---|---|
| Broad discovery | Search official portals with broad phrases like startup grants, R&D grants, innovation funding, SBIR, EIC Accelerator, and Innovate UK grants. | Grant titles rarely match founder language exactly. |
| Program discovery | Check program pages such as SBIR/STTR topics, NSF America's Seed Fund, EIC Accelerator, UK Innovation Funding Service, and Eurostars. | Program pages explain applicant type, technology stage, and call cadence better than generic directories. |
| Fit screening | Apply the six filters: geography, applicant type, TRL, fundable activity, deadline, and evidence readiness. | This removes most bad-fit calls before they steal proposal time. |
| Shortlist ranking | Rank the remaining calls by strategic fit, deadline pressure, award size, and evidence gap. | The best grant is not always the largest grant. It is the one you can credibly win. |
The goal is not to collect 50 possible grants. The goal is to identify the 3 to 7 opportunities that deserve a real go/no-go discussion.
Treat the search as a repeatable operating rhythm, not a one-off browser session. Grant portals change, calls close, and new topics appear under language that may not mention your exact sector. A simple search log with source URL, deadline, fit reason, rejection reason, and next action prevents the team from rediscovering the same weak-fit programmes every month.
Where to search
Start with official sources. They are less convenient than listicles, but they show live calls, formal deadlines, eligibility rules, and funder language.
| Region or program | Best starting point | Use it for | Watch-out |
|---|---|---|---|
| US federal grants | Simpler Grants.gov and Grants.gov | Searching federal opportunities by keyword, status, eligibility, agency, category, date range, and deadline. | Many federal opportunities are not written for startups. Screen eligibility before reading the full call. |
| US R&D and deeptech | SBIR.gov funding opportunities | Finding SBIR/STTR topics and solicitations by agency and topic area. | Agency fit matters. A strong NSF-style project can still be a bad fit for a defense topic, and vice versa. |
| Early-stage US deeptech | NSF America's Seed Fund | Checking whether your startup has a technology-driven R&D project that fits NSF SBIR/STTR expectations. | You still need a credible commercial path; technical novelty alone is not enough. |
| UK business support | GOV.UK business finance support | Filtering government-backed support by support type, stage, industry, employees, and region. | Regional and company-stage rules can make a good-looking grant irrelevant. |
| UK innovation competitions | Innovation Funding Service | Finding active Innovate UK and government innovation competitions with opening and closing dates. | Each competition has its own scope, partner rules, subsidy rules, and eligible costs. |
| EU scale-up and breakthrough innovation | EIC Accelerator | Assessing EU startup and SME support for high-impact innovations, often around TRL 6-8. | EIC can include grant and investment components. Match the funding type to your stage and dilution plan. |
| International collaborative R&D | Eurostars | Finding SME-led international R&D collaboration funding. | Consortium rules and funding rates vary by country. Do not treat it like a single-country grant. |
Use commercial grant finders and curated lists as secondary discovery tools, not as the source of truth. The official call page is what determines whether you can apply.
Six fit filters
The fastest way to improve a grant search is to reject weak-fit opportunities earlier. A deeptech company should screen every grant with the same six questions.
| Filter | Question to ask | Fast rejection signal |
|---|---|---|
| Geography | Where must the applicant be registered and where must the work happen? | The call requires a country, state, or region where you have no eligible entity or project activity. |
| Applicant type | Can a startup, SME, small business, or consortium lead apply? | The call is for universities, nonprofits, public bodies, or established companies only. |
| Technology stage | Does your current maturity match the expected TRL or project phase? | The call funds demonstration and scale-up, but your core technical risk is still unresolved. |
| Fundable activity | Does the grant pay for research, prototype work, validation, demonstration, commercialisation, or hiring? | You need runway or sales spend, but the call only funds defined R&D activities. |
| Deadline and cadence | Is there enough time to build a credible application? | The deadline is close and you do not yet have partners, budget logic, or evidence. |
| Evidence readiness | Can you show technical novelty, market need, team capability, budget rationale, and commercial path? | You can describe the idea, but cannot yet support the claims reviewers will score. |
This filter is especially important for startup grants because many pages rank for the same broad keywords while serving completely different applicant types. A founder can lose days reading grants that were never designed for their company.
30-minute workflow
Do not start by writing. Start by creating a shortlist that can survive a go/no-go review.
- Write a one-sentence funding profile: company location, technology area, current TRL, next milestone, funding need, and target geography.
- Search two broad phrases and two program phrases. For example: startup grants, grants for tech startups, SBIR grants, and NSF Seed Fund.
- Open only official call pages or program pages for the first pass.
- Save opportunities with title, funder, URL, deadline, geography, applicant type, funding amount, and one-line fit note.
- Reject anything that fails geography, applicant type, technology stage, or fundable activity.
- Rank the survivors by deadline, fit, award size, and evidence gap.
- Move the top 3 into a roadmap and run a separate eligibility check before drafting.
For most deeptech teams, this workflow is more useful than a long grant database export. It makes the next action obvious: ignore, monitor, partner-search, eligibility check, or start a draft.
Example searches
Search using funder language, not only founder language. Funders are more likely to say R&D, innovation, commercialisation, demonstration, or small business than deeptech.
| Company type | Search phrases to try | Programs to check first |
|---|---|---|
| AI infrastructure or advanced software | startup grants, grants for tech startups, AI SBIR, non-dilutive funding for startups | SBIR.gov topics, NSF Seed Fund, EIC Accelerator Challenges, Innovate UK competitions |
| Climate hardware or energy systems | R&D grants, energy innovation funding, climate tech grants, demonstration grant | DOE SBIR/STTR, EIC Accelerator, Eurostars, Innovate UK energy competitions |
| Bio, health, or medtech | NIH SBIR, health innovation grant, medical device R&D grant, clinical validation funding | NIH SBIR/STTR, EIC Accelerator, Innovate UK life sciences calls |
| Aerospace, robotics, or dual-use | DOD SBIR, DARPA BAA, autonomy funding, advanced manufacturing grant | SBIR.gov, defense agency solicitations, Innovate UK, EIC Accelerator |
| University spinout | STTR, technology transfer grant, proof of concept funding, collaborative R&D | STTR, NSF Seed Fund, Eurostars, national innovation agencies |
When a search returns too many generic small-business results, add the fundable activity: prototype, R&D, feasibility, demonstration, pilot, validation, or commercialisation. When it returns too few results, remove the sector and search by program family.
What to ignore
The best grant searchers are good at saying no. A bad-fit grant has an opportunity cost even if the application is free.
| Bad-fit pattern | Why it wastes time | Better move |
|---|---|---|
| Generic small-business grants with no R&D scope | They may fund local business activity, training, or equipment, but not technical risk. | Use them only if the activity directly matches your immediate need. |
| Calls outside your geography | You may be ineligible even if the technology fit is perfect. | Track the funder for future expansion, but do not draft now. |
| Consortium grants without a partner | Partner search can take longer than the application window. | Move it to partner-development unless the deadline is far enough away. |
| Scale-up grants before proof | Reviewers expect evidence you cannot yet provide. | Look for feasibility, Phase I, proof-of-concept, or early R&D funding. |
| Deadlines too close for a first application | A rushed application can damage the same opportunity family later. | Save the call, learn the rules, and target the next cycle. |
This is where startup-grant search becomes strategy. The right answer is often not "apply now". It might be "wait for the next call", "find a consortium partner", "collect validation data", or "choose a smaller proof-of-concept grant first".
Search routine
A grant search should be a recurring operating habit, not a panic task two weeks before a deadline.
| Cadence | Action | Output |
|---|---|---|
| Weekly | Check saved searches on official portals and scan new calls in your core geographies. | New, changed, and closing-soon opportunities. |
| Monthly | Re-rank the shortlist against company milestones, runway, TRL, and evidence gaps. | Updated funding roadmap. |
| Before drafting | Run the eligibility checklist and write a one-page fit memo. | Go/no-go decision. |
| After rejection or pass | Record why the call failed: eligibility, scope, timing, team, budget, or evidence. | Sharper filters for the next search. |
A founder should be able to explain why every grant is on the shortlist. If the answer is only "it has funding available", the opportunity is not ready for drafting.
