Start with the research problem, then find the right agency
SBIR and STTR fund eligible small businesses doing research and development with commercial potential. The strongest starting point is a technical problem, a testable research plan and an agency whose mission fits the work. They are not general grants for launching any small business or paying ordinary marketing expenses.
This guide helps you build a focused opportunity shortlist, separate SBIR from STTR and keep evidence, deadlines and application work organized. It explains the process without promising an award or deciding your eligibility.
Current status: reauthorized does not mean every topic is open
DOE's current program page says the April 13, 2026 law extends SBIR/STTR through fiscal year 2031. That supersedes older authorization-lapse messages, but individual opportunities still have their own intake windows. DOE current SBIR/STTR overview.
| Example checked October 1, 2026 | What the official source says | What to do |
|---|---|---|
| NSF | The current funding page lists a November 4, 2026 full-proposal deadline. Its entry process includes a suitability assessment and Project Pitch. | Confirm the current solicitation and your invitation path before preparing a full proposal. NSF funding page; NSF application process. |
| NIH parent SBIR PA-27-100 | The government opportunity record lists an April 5, 2027 closing date. | Read the NOFO for receipt dates, scope and clinical-trial conditions; a closing date is not every possible submission date. Official PA-27-100 record. |
| EPA Phase I | EPA lists its 2026 solicitation as open September 24 through November 8, 2026. | Check the actual topic, submission instructions and time zone. EPA application instructions. |
| DOE Genesis Mission Phase I | The current OTC page says submissions are closed; a broader Phase I opportunity is expected later in fall. | Monitor the new opportunity. Do not submit to an expired call or treat an expected release as open. DOE opportunity status. |
These are dated examples, not a complete live calendar. Recheck the agency immediately before investing time in a submission.
SBIR versus STTR: what changes for your team?
Both programs support R&D, but STTR requires the small business to formally partner with a qualifying research institution. That changes the team and coordination work, not just the acronym on a form. SBA's overview also distinguishes feasibility work, further development and commercialization; Phase III does not receive SBIR/STTR funding. SBA program and application overview.
For a university-linked company, map the company and institution's actual roles before selecting STTR. For a company building independently, investigate SBIR and the particular agency's collaboration rules. Confirm ownership, location, staffing and work-allocation requirements in the current solicitation rather than assuming one agency's checklist covers another.
The agency map
The table is a mission-level discovery aid, not a statement that every listed agency has an open call today. SBA's agency directory is the central starting point; agency solicitations govern the actual application. Participating agency directory.
| Agency route | Research direction | Next check |
|---|---|---|
| NSF | Deep technology across many markets | Read the agency's current solicitation and topic, not just this category. |
| NIH and HHS | Biomedical and health research | Read the agency's current solicitation and topic, not just this category. |
| DOE | Energy and scientific technology | Read the agency's current solicitation and topic, not just this category. |
| NASA | Space, aeronautics and enabling technologies | Read the agency's current solicitation and topic, not just this category. |
| USDA NIFA | Agriculture, food and rural technologies | Read the agency's current solicitation and topic, not just this category. |
| EPA | Environmental technology | Read the agency's current solicitation and topic, not just this category. |
| Commerce: NIST and NOAA | Measurement, standards, ocean and atmospheric missions | Read the agency's current solicitation and topic, not just this category. |
| Defense SBIR/STTR | Warfighter and defense mission topics | Read the agency's current solicitation and topic, not just this category. |
| Education | Educational technology | Read the agency's current solicitation and topic, not just this category. |
| Homeland Security | Security, resilience and first-responder missions | Read the agency's current solicitation and topic, not just this category. |
| Transportation | Transportation-system technologies | Read the agency's current solicitation and topic, not just this category. |
Build an opportunity receipt before writing the application
Use one short record for each candidate. This original framework turns a broad grant search into a decision the team can explain:
- Mission: which agency need does the project address?
- Technical uncertainty: what is not yet known, and what experiment would resolve it?
- Commercial path: who could use the result, and what evidence supports that use?
- Team: who does the work, with which partners and facilities?
- Intake: solicitation ID, topic, current status, deadline and required entry step.
- Evidence: official links, date checked, missing documents and unanswered questions.
SBIR.gov warns that its copied topic listings may not be the latest version. Use the directory for discovery, then capture the authoritative agency notice in your receipt. SBIR topic-search notice.
A worked example: one sensor, three possible routes
Illustrative demonstration: a startup is developing a sensor for detecting contaminants in process water. “Water technology” alone is not enough to choose a program. The team creates three research records:
| Route | Why investigate | What must be established | Decision now |
|---|---|---|---|
| EPA | Environmental mission | An open topic matches the contaminant and test setting. | Read current topic before drafting. |
| NSF | Deep technical uncertainty with commercial potential | The research challenge fits the entry process and current solicitation. | Prepare suitability assessment and pitch materials. |
| DOE | Possible energy or scientific use | A current mission topic genuinely fits; the closed Genesis call is not an application route. | Monitor, not “apply now.” |
The example does not conclude that the company qualifies or predict selection. It shows how the same technology produces different evidence and next steps.
Make application preparation a connected workflow
Use Finta CRM to track agency and support contacts, opportunity records and next conversations. Keep the solicitation, research brief and source index in Documents. Ask Aurora to organize available evidence, compare requirements and draft a preparation checklist for review. Finta does not determine federal eligibility or promise to submit through agency portals.
For a broader pre-revenue budget, use the pre-revenue funding guide. For energy-related routes beyond SBIR, compare the US climate-tech funding programs guide.
Methodology and limitations
Finta Editorial Team reviewed current agency and government opportunity pages on October 1, 2026. The mission map is intentionally broader than the dated intake examples. This is a general discovery and organization guide, not an exhaustive calendar, a grant-writing service or an eligibility opinion. Confirm the latest notice, local and federal requirements, dates, registrations and research rules with the responsible agency.
