How to Win SBIR Phase II: From Phase I Evidence to a Fundable Plan
Phase II is where SBIR budgets and transition pressure rise. Use prior awards, agency conversion rates, and customer pull to build a Phase II bid you can defend.
Phase I proves a concept. Phase II is where agencies decide whether your approach deserves real development money — and whether you look like a future transition partner. Winning Phase II is less about “writing harder” and more about assembling evidence, customer pull, and a transition story the government can fund.
This guide is for small defense and dual-use firms that already have Phase I results (or a Direct-to-Phase II path) and need a practical capture plan.
1. Start with evidence, not enthusiasm
Phase II reviewers expect you to show what Phase I (or equivalent work) changed: technical risk reduced, metrics improved, prototypes that exist, data that can be replicated. If you cannot point to concrete outputs, pause and close the gaps before you open a bid package.
Use public award history to benchmark peers:
- Find similar firms on awardee intelligence and individual battlecards.
- Study Phase I→II conversion by agency so you know whether the slice you are in actually advances work past Phase I.
- Open the agency hub (for example agency profiles) to see who wins and which tech areas get dollars.
2. Map the customer, not just the topic text
SBIR Phase II succeeds when a real organization wants the outcome. Identify:
- Who funded related work (agency + sub-agency on prior awards).
- Whether incumbents already own the topic family.
- Whether you have a path to a customer memorandum, TPOC engagement, or end-user trial for transition programs.
Opportunity pages on SBIR Signal include competitive intel (incumbents, conversion signals, related awards). Treat that as your first competitive pass, then dig into primary sources on DSIP/SAM as needed.
3. Build a Phase II work plan that de-risks transition
Strong Phase II plans answer three questions:
- Technical: What will be true at the end of Phase II that is not true today?
- Programmatic: What milestones, tests, and TRL movement will a PM recognize?
- Transition: Who pays next — Phase III, program of record, STRATFI/TACFI-style matching capital, or commercial dual-use revenue?
If your answer to (3) is “we will figure it out later,” you are bidding a longer Phase I, not a Phase II.
Tools that help structure the bid without inventing requirements:
- Capability match — rank open topics by fit.
- Readiness scorecard — firm-level readiness before you commit scarce proposal capacity.
- Proposal workbench (Pro) — requirements, compliance checklist, win themes, past performance from award history.
- Transition hub — Phase II/III readiness checklist for post-Phase II capital paths.
4. Respect competition and proposal caps
Under the 2026 reauthorization environment, firms must treat proposal slots as scarce. See what changed in 2026 and the proposal submission caps hub. Do not burn a Phase II bid on a topic you would fail in a 15-minute vetting checklist.
5. Package past performance like a contractor, not a grant applicant
Phase II is procurement-flavored. Your narrative should sound like a firm that delivers under government terms:
- Prior SBIR/STTR awards with phase, agency, and outcomes (browse your firm on award pages and the award search).
- Key personnel who match the work plan.
- Facilities and subcontractors that close capability gaps (see teaming).
- Clear eligibility posture (size, ownership, SAM) — eligibility cockpit.
6. Plan the day after Phase II
Agencies fund Phase II more readily when they can see what happens next:
- Phase III — non-SBIR follow-on; watch firms already at Phase III on the transition hub.
- STRATFI / TACFI-style paths — matching funds and customer pull (confirm current NOO rules on AFWERX/SpaceWERX).
- Commercial dual-use — revenue that does not depend on the next set-aside award.
A practical Phase II capture sequence
- Confirm eligibility and capacity (scorecard + eligibility cockpit).
- Shortlist topics with capability match and conversion data.
- Study incumbents and related awards (battlecards + award pages).
- Draft the work plan and transition story before the technical essay.
- Only then write the proposal — and submit through the official portal on time.
Phase II is winnable when your evidence, customer, and transition path are visible in the same package. Use public award data as competitive intelligence, not as a substitute for primary solicitation requirements.

Frequently asked questions
Do I need a Phase I award to bid Phase II?
Usually yes for sequential topics — Phase II builds on Phase I results. Some agencies offer Direct-to-Phase II (D2P2) paths for firms with equivalent prior work; read the solicitation carefully.
What do agencies look for in a Phase II proposal?
Evidence that Phase I (or equivalent) reduced technical risk, a clear work plan, realistic milestones, and a credible path to transition or commercialization beyond the set-aside.
How do I research Phase II competition?
Review prior winners on the same topic family, Phase I→II conversion by agency, and firm profiles. SBIR Signal surfaces these on opportunity and award pages from public federal data.
What comes after a Phase II win?
Phase III (non-SBIR follow-on), STRATFI/TACFI-style transition capital, or commercial dual-use paths. Map that path before you bid Phase II.
