What STRATFI and TACFI are (and what they are not)
STRATFI — Strategic Funding Increase — and TACFI — Tactical Funding Increase — are transition vehicles run by AFWERX within the Department of the Air Force. They are not new SBIR phases. They are supplements to an existing Air Force or Space Force SBIR Phase II, engineered to bridge the gap between a successful prototype and a fielded capability funded through program-of-record dollars. In a portfolio where most SBIR prototypes die between Phase II and Phase III — the so-called valley of death — STRATFI and TACFI are the most effective vehicle the Air Force has built to carry them across.
The operating model is straightforward: SBIR funds are provided as a matching augmentation, paired with committed funds from a government program office (the transition partner) and private capital from investors or the company itself. The match structure creates the forcing function — an operational sponsor has to put real dollars on the table, which is the best signal the government can produce that a capability is actually wanted. Without the sponsor match, the augmentation does not happen. That single rule eliminates most "nice-to-have" transitions.
What STRATFI and TACFI are not: they are not a way to backdoor into Air Force contracting if you have never won a Phase II. They are not general-purpose R&D funding. They are not a substitute for a program of record — if no program office wants the capability, no amount of STRATFI paperwork will create one. Firms that misunderstand this pitch their board on "we'll do STRATFI" before they have a sponsor, and that is the path to a slow decline.
AFWERX STRATFI — Application to Award
Dollar ranges and cost-share structure
STRATFI total program value can reach approximately $15M across the three funding streams. The SBIR contribution is capped at $3M, with the government transition partner contributing up to $9M of program-office funds and private capital contributing up to $3M. In practice, the distribution is flexible within the total cap — what matters is that all three streams show up in material amounts. A STRATFI deal with no private capital or no government match gets rejected.
TACFI is the smaller cousin. SBIR contribution is up to roughly $1.5M, with smaller expected matches from government and private sources. TACFI is built for capabilities that need an incremental push rather than a full transition program — typically when a Phase II prototype is close to operational use and needs a final integration push, additional T&E, or a small-scale initial deployment.
The cost-share ratios shift the economics for a small firm. A $3M SBIR contribution plus $9M program-office funds plus $3M private capital is a $15M program in which the firm's out-of-pocket is the smallest slice. For founders who have done Phase I and Phase II on non-dilutive terms, the private-capital requirement is a new constraint — but it is also a forcing function for commercial investment, which in turn signals to the government that the capability has a civilian market.
How STRATFI differs from standard SBIR Phase II
A standard SBIR Phase II is typically a single-stream $1.7M to $2M award for 18 to 24 months of prototype development. The scope is defined by the topic. The customer is typically the program office that wrote the topic, but the Phase II does not require a binding commitment from that customer beyond writing the topic. STRATFI changes the structure in three ways that matter.
First, the customer commitment is binding. The operational sponsor must provide committed funds, which requires program-office leadership sign-off. This is the single biggest filter — most Phase IIs do not reach the level of sponsor commitment STRATFI requires, which is why STRATFI awardee counts are smaller than Phase II awardee counts.
Second, the scope is a transition plan, not a prototype plan. STRATFI applications describe how the capability moves from prototype to fielded use: integration, test, fielding infrastructure, training, sustainment. Firms that treat STRATFI as "Phase II but bigger" and write prototype-focused applications are rejected.
Third, the private capital requirement turns STRATFI into a hybrid commercial/federal instrument. Investors are evaluating the same deal the government is evaluating, with complementary incentives. The deal is not closed until all three parties are aligned, which is slower than a traditional Phase II but produces much higher transition probability once it closes.
The AFWERX Open Topic pathway vs solicitation SBIR
AFWERX runs both Open Topic and traditional solicitation SBIRs. Open Topic is the more distinctive vehicle: the Air Force does not write the topic; the firm proposes the problem and the solution. Open Topic Phase I awards are smaller, on a pitch-day cadence, and are designed to produce a rapid go/no-go. Open Topic Phase II awards feed directly into the STRATFI/TACFI pipeline, and the Open Topic structure is explicitly built to surface capabilities with operational pull.
Traditional solicitation SBIR topics at Air Force are written by program offices against specific needs. They are closer to how Army, Navy, and DARPA work. Both paths can lead to STRATFI, but Open Topic is architecturally oriented toward transition in a way that traditional solicitation SBIRs are not. A firm choosing between the two should weigh whether it has a clearer story as "here is a problem we understand" (traditional) or "here is a capability the Air Force does not yet know it needs but will want" (Open Topic).
For AI/ML firms, Open Topic has been the more productive route in recent cycles. The flexibility to define the problem lets a firm match an existing model or tool to a plausible operational need without being constrained by a program office's preconceived approach.
Eligibility: Phase I or Phase II win required
STRATFI and TACFI are transition vehicles, which means a firm must hold an Air Force or Space Force SBIR Phase II to apply — active or recently completed. The eligibility rule exists to prevent STRATFI from becoming a general-purpose back-door. Firms that want STRATFI must first win a Phase II, which means planning STRATFI into the Phase I application, not waiting until Phase II is underway.
Practically, this creates a year-plus lead time from first Phase I submission to first STRATFI award. Firms that treat STRATFI as their business model must plan Phase I and Phase II with transition potential baked in from the start. Firms that win Phase I opportunistically and only later consider STRATFI usually find their Phase II topic does not lend itself to a transition story, and the opportunity evaporates.
What the evaluation panel looks for
The evaluation considers four things: the strength of the transition plan, the credibility of the government sponsor commitment, the fit of the capability to an identified Air Force need, and the commercial viability evidenced by the private capital match. Technical merit is assumed — the firm already won Phase II. STRATFI evaluation is about transition, not technology.
Evaluators want to see a specific program of record or mission area that needs this capability, a named sponsor who has committed funds, a realistic integration and fielding plan, and a commercial story that justifies the private investment. The document should read as a business case for a capability that happens to have a technical component, not as a technical proposal that mentions transition in passing.
Weak STRATFI applications share a pattern: vague sponsor ("we are in discussions with multiple program offices"), vague transition plan ("upon success we will pursue Phase III"), and vague commercial story ("there is a large potential market"). Strong applications name the program, name the sponsor, quote the committed dollar amount, specify the integration path, and describe the commercial use case with actual customers.
Positioning an AI/ML prototype for STRATFI
AI/ML prototypes are well-suited to STRATFI if they have been built with fielding in mind. That means the model has been evaluated against mission-representative data, the inference stack is deployable in target environments (cloud, edge, or disconnected), the assurance story is documented to NIST AI RMF expectations, and the integration path into existing Air Force systems is concrete. Prototypes that hit these marks are easy to write a STRATFI application around.
Prototypes that struggle are those that demonstrated model performance on laboratory data, have no deployment story, and no assurance documentation. Even if the model is genuinely better than whatever the Air Force is using today, the transition friction kills the application. The remediation is to spend Phase II months 6 through 12 building the fielding story — packaging, deployment scripts, inference hardware compatibility, assurance artifacts — rather than only refining the model.
The other positioning lever is the sponsor relationship. A STRATFI application with a sponsor who has been in the room since Phase I is materially stronger than one where the sponsor was recruited in the last quarter of Phase II. Founders who invest in sponsor relationship-building from month one of Phase I build optionality that pays off at STRATFI time.
Timeline from application to award
STRATFI applications are reviewed on a rolling basis, not on fixed cycles, which makes timing more flexible than standard SBIR cycles. From a well-prepared submission, evaluation runs four to eight weeks, followed by two to four weeks of match negotiation and agreement before the award is executed. The practical timeline is two to four months from submission to contract start, assuming the sponsor commitment and private capital are already in place.
The long pole is usually not the AFWERX review. It is the sponsor commitment paperwork and the private capital close. Firms that treat STRATFI as a three-month project starting when the Phase II ends often run out of Phase II runway before the STRATFI closes. The correct posture is to begin STRATFI preparation in Phase II month 6 — identify sponsor, build the match case, begin private-capital conversations — so that the application is ready to submit around month 15 of Phase II.
Bottom line
STRATFI and TACFI are the most effective transition vehicles the Air Force has built for SBIR prototypes. They reward firms that treat Phase I and Phase II as a transition runway rather than a prototype exercise, and they filter out firms whose capabilities lack operational pull. For an AI/ML firm with a real Phase II and a real sponsor, STRATFI is the path from prototype to program-of-record — which is the path to real federal revenue.
Frequently asked questions
STRATFI is a transition supplement to a Phase II, not a replacement for it. It pairs SBIR funds with a committed government program-office match and private capital. A Phase II is a prototype award; STRATFI is a transition award that moves the prototype toward a fielded program of record.
Up to roughly $15M total program value: up to $3M SBIR contribution, up to $9M government program-office match, and up to $3M private capital match. TACFI is smaller, up to about $1.5M SBIR with proportional matches.
Yes. An active or recently-completed Air Force or Space Force Phase II is required. STRATFI is a transition vehicle, not an entry point.
Two to four months from a well-prepared submission, with evaluation running four to eight weeks and match negotiation adding another two to four weeks. The bottleneck is usually sponsor paperwork and private-capital close, not the AFWERX review.
Yes, and it is one of the most active STRATFI categories. AI/ML prototypes with deployment-ready packaging, documented assurance, and a named operational sponsor fit the model well. Research-heavy prototypes without a fielding story do not.
