What you get
- Proposal support for NIH, NSF, and DoD, from Specific Aims through the commercialization plan.
- Written by a doctoral-level consultant who frames the technical objectives the way reviewers score them.
- SBIR is non-dilutive funding, so a successful award does not cost you equity.
- Honest about odds: roughly 10 to 15 percent of applicants win a Phase I, and we never guarantee an award.
SBIR grant writing services help startups and small businesses turn a technical innovation into a competitive Small Business Innovation Research (SBIR) or Small Business Technology Transfer (STTR) proposal. At Grant Writing Service, a doctoral-level SBIR grant writer writes the Specific Aims, the research plan, and the commercialization plan for NIH, NSF, and DoD opportunities, then delivers a submission-ready package. SBIR provides non-dilutive funding to startups, so a successful award advances your technology without costing you equity.
Who needs an SBIR grant writer
These programs reward a specific skill: framing deep technical work so non-specialist reviewers and program officers can score it quickly and confidently. Founders who are brilliant engineers or scientists often lose points not on the science but on the structure, the Specific Aims, or a commercialization story that reads as an afterthought.
We work with pre-seed and seed-stage technology companies, university spinouts, and research-driven small businesses pursuing non-dilutive funding before or alongside venture capital. If you are weighing federal programs more broadly, our federal grant writing service covers the wider agency landscape, and our small business grant writer service helps for-profit founders find the right fit among grant types.
Agencies we write for: NIH, NSF, and DoD
Each agency runs SBIR and STTR differently, and the format that wins at one can sink an application at another.
- NIH uses a study-section peer review and rewards a tight Specific Aims page, strong preliminary data, and a clear path to a health outcome. Applications route through eRA Commons.
- NSF, through America's Seed Fund, emphasizes technical risk, intellectual merit, and a credible commercial path, with submissions through Research.gov.
- DoD ties topics to specific mission needs published in its solicitations and weighs transition to a military or dual-use market.
Knowing these differences is half the work. Our guide to writing a competitive SBIR proposal breaks down what each agency emphasizes and how to read a solicitation.
Our SBIR process from Specific Aims to commercialization
Every engagement follows a research-disciplined path.
- Fit and eligibility. We confirm your company qualifies, identify the right agency and topic, and check registration in eRA Commons or Research.gov.
- Specific Aims. We draft the page that frames everything else. Specific Aims frame the proposal's technical objectives and set the logic reviewers follow.
- Research plan. We write the technical narrative, innovation, approach, and risk mitigation, integrating your preliminary data.
- Commercialization plan. We build the market, customer, and revenue story that turns research into a fundable business case.
- Review and submission. We run a responsiveness pass against the solicitation and support submission.
STTR requires a research-institution partner, and we structure the work split and the partner letters when your project runs through that program. When you are ready to scope a submission, get an SBIR proposal quote and a consultant will map the work to your deadline.
Phase I versus Phase II support
The programs run in stages, and each demands a different proposal.
| Stage | Purpose | Proposal focus |
|---|---|---|
| Phase I | Prove technical feasibility | Specific Aims, approach, risk, feasibility milestones |
| Phase II | Scale a successful Phase I | Expanded development, deeper commercialization plan, data from Phase I |
Phase II scales a successful Phase I, building on the results you generated and the relationships you formed with your program officer. Our comparison of how Phase I and Phase II differ explains how to position each so the second application reads as a natural continuation of the first.
Realistic odds and how we improve them
We will not promise an award, and you should be wary of anyone who does. NSF and federal data indicate only 10 to 15 percent of applicants win a Phase I, with rates varying by agency, topic, and year. The honest picture matters because it shapes how you invest your time.
What a strong writer changes is which tier your proposal lands in. A responsive Specific Aims page, a credible commercialization plan, and a research plan that addresses reviewer concerns before they arise move you out of the easy-reject pile and into the competitive range agencies actually fund. Our analysis of what the SBIR success rate really means puts the numbers in context so you set realistic expectations.
Why the Specific Aims page decides everything
In an SBIR or STTR proposal, the Specific Aims page does more work than any other single piece. Reviewers form an opinion there, often before they read the full research plan, and that first impression colors every score that follows. A muddled Aims page rarely recovers, no matter how strong the science underneath.
A winning Aims page does three things in one tight page. It states the problem and why it matters commercially and technically. It frames two or three clear, testable objectives that a reviewer can hold in mind. And it previews the payoff, the feasibility you will prove and where it leads. We draft this page first and revise it most, because getting it right pulls the rest of the proposal into focus. Our walkthrough of how to write Specific Aims that reviewers reward breaks down the structure line by line.
The commercialization plan is not an afterthought
Founders with deep technical backgrounds often treat the commercialization plan as paperwork to satisfy after the science is done. Agencies read it as a core scoring element, and at NSF through America's Seed Fund the commercial potential carries real weight. A proposal with brilliant science and a thin market story loses to one with strong science and a credible path to revenue.
We build the commercialization plan as a genuine business case: the customer, the market size, the competitive landscape, the regulatory path where one applies, and the revenue model. Because SBIR provides non-dilutive funding to startups, the program is effectively asking how this public investment becomes a viable company, and the answer has to be specific. This is also where federal program overlap helps; our federal proposal expertise informs how agencies weigh public benefit against commercial return.
Timing and registration realities
An SBIR submission is not something to start the week before a deadline. Registration alone, through eRA Commons for NIH or Research.gov for NSF, can take weeks, and a lapsed or incomplete registration will block a submission no matter how strong the proposal. We confirm your registrations early and build the writing timeline backward from the deadline with room for internal review.
A realistic schedule runs four to eight weeks for a Phase I, longer when preliminary data is still coming together or when an STTR research partner has to be coordinated. Rushing compresses the Specific Aims revisions and the commercialization plan, the two sections that most affect the score, which is exactly the wrong place to save time.
Why flat-fee, never commission
We quote a flat fee before any work starts, and we never charge a percentage of the award. Contingency pricing violates GPA ethics, and on federal funding, success-based fees are an unallowable cost. A flat fee keeps your budget clean and our incentives aligned with yours, which matters when you are conserving every non-dilutive dollar.
Proof and credentials
Your proposal is led by a doctoral-level consultant and grounded in primary sources: the agency solicitation, SBIR.gov program rules, NSF America's Seed Fund guidance, and NIH application instructions (2026). We write to the review criteria each agency publishes, not to a generic template.
We are honest about outcomes. The study section or panel makes the final decision. What we deliver is a responsive, technically rigorous, commercially credible proposal that gives your innovation its strongest possible chance.
How to get started
Send us the agency, the topic or solicitation number, and a short description of your technology, and a consultant will return a written, flat-fee quote, usually within one business day. Nothing is due until you approve the scope and price.
