How to Find Open SBIR Phase I Opportunities Right Now

If you are a founder looking at SBIR Phase I funding, the hardest part is not writing the proposal. It is finding the right open solicitation in the first place. The federal government runs SBIR through eleven participating agencies, each with its own calendar, topics, and submission portal. There is no single search box that does this well.

Here is the practical workflow for finding currently open Phase I opportunities, what each agency is good for, and the search tactics that beat just typing keywords into SBIR.gov.

The Eleven Agencies

The SBIR program is statutorily structured across eleven participating federal agencies. Each runs its own program with its own topic areas and deadline cycles:

Department of Defense (DoD) — Largest by dollar volume, runs three open solicitations per year across the services (Army, Navy, Air Force, DARPA, MDA, DTRA, others)
NIH — Health-focused, runs omnibus topics three times per year plus targeted RFAs
NSF — Open topic solicitations, runs America's Seed Fund
Department of Energy (DOE) — Energy, climate, nuclear, advanced computing
NASA — Space and aeronautics technology
USDA — Agriculture, rural development, food systems
DHS — Homeland security and counter-threat tech
Department of Education — Education technology
Department of Transportation (DOT) — Transportation infrastructure and safety
EPA — Environmental tech
Department of Commerce (NOAA + NIST) — Climate, ocean, measurement science

The official SBIR portal is at sbir.gov. Every agency feeds into it, but the search interface there is incomplete enough that you should not rely on it as your only source.

Where to Actually Look

1. Start with SBIR.gov Solicitation Search

Go to sbir.gov/solicitations and filter by "Open" and "Phase I." This will return active solicitations across all eleven agencies, but the metadata is sometimes lagged by a few days behind agency-direct postings.

Sort by "Close Date" ascending to see what is closing soonest. Phase I budgets usually run $250,000 to $314,000 depending on agency, with performance periods of six to twelve months.

2. Cross-Check Each Agency's Direct Portal

SBIR.gov occasionally misses topics. Verify by hitting each agency's direct page:

DoD: dodsbirsttr.mil — The DoD SBIR/STTR site shows topics by Component (Army, Navy, AF, etc.) and includes Direct to Phase II opportunities that SBIR.gov sometimes omits
NIH: sbir.nih.gov plus grants.nih.gov — NIH posts targeted Phase I RFAs that are sometimes more lucrative than omnibus topics
NSF: seedfund.nsf.gov — NSF America's Seed Fund accepts Project Pitches on a rolling basis before formal proposal invitation
DOE: science.osti.gov/sbir — DOE topic releases are large PDFs; the EERE and Office of Science topics are funded differently
NASA: sbir.nasa.gov — NASA topics tend to require specific subtopic alignment and ties to active mission directorates

3. Use Grants.gov as a Backstop

Grants.gov is the official catalog of federal funding opportunities. SBIR solicitations are posted there as well, often with additional metadata not in SBIR.gov. Search by CFDA number (47.082 for NSF, 10.212 for USDA, 81.049 for DOE Office of Science, etc.) or filter by "Grant" type and search "SBIR" in keywords.

4. Subscribe to Agency Mailing Lists

DoD SBIR has a free notification list. NIH publishes the NIH Guide for Grants and Contracts daily. NSF America's Seed Fund publishes a topic preview before each formal release. Subscribe to all of them. The lead time between announcement and close is sometimes only 30 to 45 days.

Search Tactics That Beat Keyword Search

Search by Topic Code, Not Keyword

Each agency has its own topic numbering system. DoD uses topic codes like A24-001 (Army), N24-001 (Navy), AF24-D-001 (Air Force Direct to Phase II). If you find a topic that matches your technology, look at past awards in the same topic code family on SBIR.gov's awards database. Repeat topics with consistent annual funding are higher-confidence targets than one-off pilots.

Search Past Awards First

This is the highest-leverage tactic and the one most founders skip. Go to sbir.gov/awards and search past Phase I awards by keyword in your space. For each relevant award:

Note which agency and which topic code funded it
Check whether that topic still exists in current solicitations
Look at the awardee company — are they a typical small business or a serial SBIR recipient? Serial recipients win because they know the system, not necessarily because their tech is better

If you find five past Phase I awards in your space, the topic code that funded them is your highest-probability target.

Filter by Direct to Phase II Eligibility

DoD and a few other agencies offer Direct to Phase II (D2P2) tracks for companies with prior non-SBIR work in the same area. If you have already done relevant R&D under another contract or with internal funds, D2P2 skips Phase I entirely and goes straight to $1M+ awards. Worth checking before you commit to a Phase I track.

Watch for Reissues

Many topics get reissued cycle after cycle with minor wording changes. If a topic closed last quarter, check whether it has been reissued under a new number. Agency program managers often reuse topics they could not fully fund the prior cycle.

What Phase I Actually Funds

Phase I funding ranges from $250,000 to $314,000 (varies by agency and program year), with performance periods of six to twelve months. The deliverable is typically a feasibility study or proof of concept, not a working product.

What Phase I is good for:

Validating a technical approach with non-dilutive capital
Establishing a relationship with a federal agency
Generating documentation and IP that supports Phase II ($1M to $2M) and follow-on commercialization

What Phase I is not good for:

Building a finished product
Funding go-to-market activity
Bridging operating expenses unrelated to the funded research

If your business model needs revenue-generating product work, SBIR Phase I is the wrong instrument. Look at SBIR Phase II Commercialization Readiness, STTR, or commercial revenue paths instead.

Realistic Timeline

From "I found a topic" to "I have a Phase I award in the bank":

30 to 60 days to write a competitive proposal
2 to 6 months from submission to award notification
30 to 60 days from award notification to contract execution and first payment

Total: 5 to 10 months from topic identification to first dollar. If you need capital faster than that, SBIR is not your path.

Avoiding the Common Mistakes

Submitting the same proposal to multiple agencies. Each agency has different requirements, evaluation criteria, and program officer preferences. A copy-paste proposal is a tell, and reviewers see hundreds.

Ignoring the commercialization plan. Phase I scores include commercialization potential. A pure research proposal with no commercialization story loses to a competitive proposal with a clear path to revenue.

Missing the small business eligibility rules. You must be a US for-profit small business, majority-owned by US citizens or permanent residents, with fewer than 500 employees including affiliates. Foreign ownership and venture-affiliate rules disqualify many otherwise-eligible founders.

Submitting at the deadline. Federal portals slow down or crash near close. Submit 48 hours early.

Get the Current Open List

Rather than visiting eleven agency portals, we publish a free snapshot of currently open federal grant opportunities, including all open SBIR Phase I and Phase II solicitations, on Kaggle.

Pull the May 2026 file here: US Federal Grant Opportunities — May 2026 on Kaggle. It includes 5,826 active grant opportunities totaling over $1.13B in funding, with SBIR Phase I filterable by agency, close date, and topic.
