If your small business does anything R&D-flavored — hardware, software, science, emerging tech — SBIR/STTR may be the best-kept path into federal work. These programs pay you to develop your own innovation, you keep your equity and your IP, and success can hand you a sole-source bridge to production contracts. Here’s how they work.

What SBIR and STTR are

SBIR (Small Business Innovation Research) and STTR (Small Business Technology Transfer) are federal programs that set aside a portion of major agencies’ R&D budgets specifically for small businesses. Participating agencies include the DoD, NIH, NASA, DOE, NSF, and others — each publishes its own topics and solicitations.

The magic word is non-dilutive: unlike venture capital, this funding doesn’t cost you equity, and you generally retain the intellectual property (with the government getting certain use rights). It’s closer to a grant/BAA than a traditional contract, though some agencies structure awards as contracts.

The difference between them: STTR requires you to partner with a research institution (a university or federal lab) and split the work — the small business performs at least ~40% and the research partner at least ~30%. SBIR has no required partner and the company performs the majority of the work itself.

The three phases

SBIR/STTR is a funnel:

  • Phase I — Feasibility. A smaller award (typically tens to a few hundred thousand dollars) to prove your concept is technically feasible. Short period of performance.
  • Phase II — Development. A larger award (often around $1M+, varying by agency) to develop a prototype based on Phase I results. Usually only Phase I winners compete.
  • Phase III — Commercialization. No SBIR/STTR funds — but this is the payoff: the government can award you sole-source production or services contracts derived from your SBIR/STTR work, without recompeting. Phase III is how R&D becomes revenue.

Award amounts are SBA guidelines, adjusted periodically and varying by agency — confirm current figures on the agency’s solicitation.

Who qualifies

Generally, you must be a for-profit U.S. small business with 500 or fewer employees, majority-owned by U.S. individuals (some agencies allow majority-VC/private-equity ownership under specific rules). The principal investigator’s employment must meet program rules, and you need an active SAM.gov registration plus registrations in SBIR.gov and the agency’s system. Watch the size and affiliation rules — they apply here too.

Why it’s worth pursuing

  • Non-dilutive capital to build your technology.
  • Past performance — a completed SBIR is a credential you can point to on future bids.
  • A customer relationship with the funding agency, built around your innovation.
  • The Phase III bridge — sole-source authority is a rare, durable advantage.

How to find and win one

  • Browse SBIR.gov and agency solicitations for topics that match what you do — you respond to the agency’s stated need, so topic fit is everything.
  • Read the solicitation like any other: understand the evaluation criteria and write to them.
  • For STTR, line up your research partner early — the partnership is a requirement, not an afterthought.
  • Think commercialization from day one; agencies increasingly weight your plan to turn the research into a real product.

The bottom line

SBIR/STTR pays small businesses to develop their own innovations without giving up equity, moving from feasibility to prototype to a sole-source path to production. If you do R&D and can map it to an agency topic, it’s one of the highest-leverage entry points in all of federal contracting.
