The single hardest part of winning a STRATFI or TACFI award isn't the pitch — it's assembling the matching funds. These bridge awards are designed to prove your technology has real pull from both a government customer and the private market, so the government only puts in its SBIR dollars once you've lined up matching capital. Here's how the math actually works.
TACFI (Tactical Funding Increase) is the more accessible of the two. It provides $375,000 to $2 million in SBIR/STTR funds, and for every $1 of that SBIR money you must secure at least $1 of matching funds — either non-SBIR government funding (another program office buying your capability) or private funding (venture capital, revenue, or strategic dollars). A single 1:1 match roughly doubles your program size.
STRATFI (Strategic Funding Increase) is built for companies ready to scale toward a program of record, and the totals run $3M to $15M over up to 48 months. The match is steeper: for every $1 of SBIR funds you need either $2 of other government funds, or $1 of government funds plus $2 of private funds. In practice most winners use the second structure — pairing a government program office's commitment with a larger private raise.
Quick math: A $3.75M SBIR slice in a STRATFI, matched by $3.75M government and $7.5M private, reaches the $15M ceiling. TACFI's 1:1 match makes a $2M SBIR into a ~$4M program.
See if you qualify for an Ansys eval The MVP playbook →Government match means real, committed non-SBIR dollars from a DoD customer — an O&M, RDT&E, or procurement line a program office is willing to put behind your capability. A TPOC's enthusiasm alone isn't a match; you need a funding commitment. Private match can include a priced venture round, strategic corporate investment, or in some cases company revenue tied to the effort. The same SBIR dollars cannot be double-counted, and the match generally must be new money aligned to the STRATFI/TACFI period of performance.
Start early — the match is a fundraising campaign, not a form. Work your TPOC and their program office to identify a government line that could commit; this is often the gating item, so begin those conversations months before the solicitation window. In parallel, line up private capital that understands defense timelines; many defense-focused VCs specifically want to co-invest alongside a STRATFI because the government dollars de-risk their check. Get soft commitments in writing so you can move fast when the Notice of Opportunity opens.
Two things trip companies up. First, timing: matching commitments have to be firm within the solicitation's window, so a maybe from an investor won't clear the bar. Second, eligibility of the funds: confirm with your contracting contact that a given source qualifies before you count on it — the current Matching Funds Guidance is published with each Notice of Opportunity and spells out exactly what's allowable.
Bottom line: treat TACFI as a 1:1 stepping stone you can reach with a single customer or investor, and STRATFI as a coordinated raise where government and private dollars arrive together. Read the current-year STRATFI/TACFI guidance before you commit, because the exact ratios and allowable sources are refreshed each program year.
