For AI startups doing genuine research and development, SBIR is one of the few sources of real non-dilutive funding — money that doesn’t take equity and doesn’t have to be repaid. This guide explains how it works in 2026, cited to official sources. (dgm builds AI; we’re not an SBIR proposal shop — see the note at the end.)

What SBIR is

SBIR — the Small Business Innovation Research program, branded “America’s Seed Fund” — funds small-business R&D with commercialization potential. The SBA coordinates it, but the money and solicitations come from 11 participating federal agencies, each running its own program under shared rules. That structure matters: there’s no single “SBIR application” — you apply to a specific agency whose mission fits your work.

Phases and award amounts

SBIR is structured in phases:

  • Phase I — feasibility. Establish technical merit and feasibility. Current SBA guidance allows awards up to about $323,090 without special approval.
  • Phase II — R&D and prototyping. Develop the innovation, with awards up to about $2,153,927.
  • Phase III — commercialization. Bringing the product to market; this phase is not funded by SBIR itself.

Those dollar caps are statutory and inflation-indexed, so they shift roughly annually — always confirm the current figures on sbir.gov before citing them in a plan.

Eligibility

To qualify, you must be a US-based for-profit small business with 500 or fewer employees, more than 50% owned by US citizens or permanent residents. Rules vary by agency — notably, some agencies permit majority venture-capital ownership and others don’t — so read the specific solicitation’s eligibility section carefully.

Why it fits AI startups

SBIR is technology-agnostic, so AI and software projects are routinely funded. The clearest example is the National Science Foundation, whose SBIR program runs a dedicated artificial intelligence topic spanning subtopics like computer vision, conversational AI, and trustworthy AI. If your startup is genuinely advancing AI — not just applying off-the-shelf models — there’s likely an agency topic that fits.

How to apply

Because each agency runs its own program, the process varies:

  • Browse open topics across agencies at sbir.gov/topics.
  • Some agencies, including NSF, require a short Project Pitch first; if invited, you submit a full proposal.
  • Register your business with the required federal systems before applying, and align your project to the agency’s stated topic.

Budget real effort: SBIR is competitive, and a strong proposal takes weeks, not days.

A realistic expectation

SBIR funds R&D, not adoption. If your plan is to roll out existing AI tools internally, SBIR is the wrong door, and the R&D tax credit or an SBA loan will serve you better. If you’re building something genuinely new in AI, it’s one of the best non-dilutive options available.

How dgm helps

dgm implements osFoundry and builds AI for US businesses. We help AI startups develop the technical capability and architecture behind a project — but SBIR proposal writing and compliance is a separate specialty, best handled with an SBIR consultant or the agency’s program manager. Think of dgm as the team that helps you build the thing the grant funds.
