SBIR Grants for Ocean Tech Startups: How the Process Works

By Founding Blue

SBIR grants for ocean tech startups come from NOAA's Small Business Innovation Research program, a competitive, merit-based federal grant that funds U.S. small businesses to research and develop commercially viable products tied to NOAA's mission. The money is non-dilutive, meaning you do not give up equity. Applications open once a year, so timing and preparation decide whether you get a turn.

What NOAA's SBIR Program Actually Funds

According to the NOAA SBIR program overview, the program encourages small businesses to take part in federal research and development with the end goal of commercially viable products or services. Its mission areas include climate and weather, oceans, coasts and fisheries, satellites and remote sensing, and charting and surveying.

Two conditions shape every proposal. The NOAA funding opportunities page states that all proposals must relate to the NOAA mission and should have commercial applications outside NOAA. A product that only NOAA would ever buy is a weak fit, and so is a good product with no connection to NOAA's topics.

For a Florida founder, that means matching your technology to a NOAA topic area first, then describing the operator, port, fleet or agency customer who would buy it. Ocean data, vessel and port operations, coastal monitoring and water quality tools can fit. Check the current topics rather than assuming your category qualifies.

How the Process Works, Step by Step

Step 1: Confirm the cycle and read the funding notice

All SBIR applications must answer NOAA's Notice of Funding Opportunity, which is published once per year on the NOAA site and on Grants.gov. NOAA's pages say the FY27 notice is expected to open in Fall 2026, and that the FY 2025 Phase I opportunity is closed. Read the full notice, because topic areas, award ceilings and rules are set there.

Step 2: Check eligibility before you write anything

The FY25 Phase I notice, summarized in the Grants.gov opportunity listing, shows how the program is structured, and the GrantExec summary of the same notice lists the practical requirements. Use the checklist below as a prompt, then confirm each item against the current notice.

The applicant must be a U.S.-based small business that can carry out the research and commercialize the result.
The principal investigator's primary employment must be with the small business, meaning at least 51% of that person's time, according to the FY25 notice summary.
The research work must be performed in the United States, with exemptions only in rare and unique circumstances approved in writing.
For Phase I, a minimum of two-thirds of the research effort must be performed by the awardee.
The small business certifies its size and ownership status at the time of award, not at application.
Cost-sharing was not required in the FY25 Phase I notice.

The principal investigator rule matters for university spinouts. If your lead researcher is still employed full time elsewhere, resolve that before you apply.

Step 3: Write to the review criteria

NOAA says it selects Phase I awards on scientific and technical merit, level of innovation and commercial potential, as described in NOAA's announcement of its Phase I awardees. Good work here is specific: a defined technical question that a feasibility test can answer, and a named customer with a stated problem.

Step 4: Run Phase I, Then Decide on Phase II

Phase I tests feasibility. Phase II is open to businesses that completed a Phase I project funded by NOAA's SBIR program in the previous fiscal year competition. Per the NOFO listing, NOAA plans to publish the Phase II notice roughly 30 days before Phase I's performance period ends, so keep your Phase I results documented as you go.

Phase I and Phase II Compared

Stage	What it is for	Amounts reported	Source
Phase I	Technical feasibility, scientific merit and commercial potential	FY25 ceiling of $190,000 in one notice summary; an earlier round offered up to $150,000 over 6 months	GrantExec summary of the FY25 notice; NOAA's Phase I awardee announcement
Phase II	Expanding on Phase I feasibility and proof-of-concept testing	Maximum of $650,000 over 2 years	NOAA's Phase II awards announcement

Amounts change between cycles, and aggregator sites do not always agree: one listing on Granted AI shows up to $175,000 for Phase I and up to $650,000 for Phase II. Treat the current NOAA notice as the only final word. NOAA's Phase II announcement also says awards went to 17 small businesses in that round, which gives a sense of how selective Phase II is.

What Reviewers and Industry Experts Ask

After Phase II, NOAA's two-year Commercialization Assistance Program ends with a workshop. According to NOAA's report on that workshop, 16 awardees gave five-minute pitches, and judges scored them on questions you can use to test a proposal before you submit:

SBIR Compared with Other Ocean Funding

SBIR is a government grant tied to a federal mission. Ocean Exchange is a nonprofit that gives annual monetary awards, including Neptune and Collegiate Awards, and its event takes place in Fort Lauderdale. The two are different processes with different criteria, and a founder can prepare for either. We do not run, judge or fund SBIR or any Ocean Exchange award, and we cannot guarantee any outcome.

Florida also has a state-supported Florida Office of the Ocean Economy, based at Florida Atlantic University, which works on ocean and coastal industries across the state. It is a useful place to learn about the sector around you, though it is not a grant program.

Where SBIR Fits on the Capital Staircase

Our capital staircase puts non-dilutive awards after proof of concept and before accelerators, seed and Series A. An SBIR grant suits that step when you have a defined commercial problem and an early prototype that needs funded testing. Our guide to non-dilutive funding for ocean tech startups covers that placement, and our funding stage guide for marine tech startups in Florida shows which help fits which stage.

When you are ready to talk to investors, a federal award can serve as outside validation of your technical claims. Our guide on how to pitch ocean tech investors in Florida covers what they want to see next. If you want to plan the order of your funding with us, our advisory services for ocean tech founders are the place to start.

FAQ

Is an SBIR grant equity or a loan?

No. It is a grant, so you do not give up ownership and do not repay it. The FY25 Phase I notice summary also says cost-sharing or matching funds were not required.

When can I apply for NOAA's SBIR program?

NOAA publishes one notice per year. Its pages say the FY27 notice will be open in Fall 2026. Phase II applications are invited through a separate notice for Phase I awardees.

Does Founding Blue write or submit SBIR applications?

No. Our application help is for Ocean Exchange's Neptune and Collegiate Awards. For SBIR we can help you plan where a federal grant sits in your funding order and refine how you explain your company, but we do not run, judge or guarantee any grant.

Can a university spinout apply?

Only if the company is a U.S. small business that meets the notice's rules, including the principal investigator's primary employment with that business at the time of award and during the project. A researcher with a full-time post elsewhere should settle that employment question before drafting a single page of the proposal.
