NASA's NIAC Phase I Just Raised Its Ceiling to $225,000 — and the Step A Proposal Is Three Pages, Due October 28

SBIR/STTR small business founders have until October 28 to compete for up to $225,000 per award from NASA's newly posted NIAC Phase I solicitation, NNH26ZTR001N-27NIAC-A1, listed on Grants.gov on September 28 as an appendix to SpaceTech-REDDI-2026.

Two details in that sentence are the whole reason to spend the next two weeks on it. The per-award ceiling went up by $50,000 from last cycle. And the front door is a three-page document.

A Three-Page Step A, Assistance Listing 43.012, and No Prime Contractor in Sight

The Grants.gov listing for NNH26ZTR001N-27NIAC-A1 is unusually legible for a NASA opportunity. Award ceiling: $225,000. Expected awards: up to 16, with the solicitation describing a range of 12 to 16. Assistance listing: 43.012, Space Technology. Funding instrument: grant — not a contract, not a cooperative agreement with a NASA center as the senior partner. Close date for Step A: October 28, 2026, at 5:00 p.m. Eastern.

Eligibility is the line that matters most for anyone who has spent a year trying to get onto a prime's team. The solicitation opens to "all categories of U.S. organizations," and NASA states plainly that NIAC Principal Investigators — the program calls them NIAC Fellows — "may be affiliated with any type of U.S. organization." A two-person LLC and a Jet Propulsion Laboratory group submit into the same pile, on the same three-page form, judged by the same panel. Non-U.S. organizations can participate on a no-exchange-of-funds basis.

The structure is two-step, and the asymmetry is the point. Step A is a short concept pitch open to everyone; NASA plans to issue Step B invitations on December 8, 2026, with invited full proposals due January 13, 2027, at 5:00 p.m. Eastern. Selections are targeted for April 2027 and awards land around July 2027. Only invited proposers write the long document. That means the real cost of entry here is three pages and a NSPIRES registration — not the four-to-six-week proposal sprint that a NASA SBIR Phase I or a research announcement typically demands. NASA held a Proposers' Virtual Forum on October 7, and the slides, FAQ, and compliance templates are posted in the NSPIRES portal.

The Ceiling Moved to $225,000 While the Cohort Got Smaller

The 2026 cycle is the comparison that tells you what changed. NASA selected 18 Phase I studies totaling $3.2 million, with each award capped at $175,000 for a nine-month investigation. The FY2027 appendix raises the cap to $225,000 — a 29% increase per award — while guiding to 12 to 16 selections instead of 18.

Run the arithmetic and the program envelope is roughly flat: 16 awards at $225,000 is $3.6 million, against last year's $3.2 million. NIAC is not getting dramatically richer. It is concentrating the same money into fewer, better-funded studies. For a founder, that cuts both ways. A $225,000 nine-month study can actually carry a loaded senior engineer, a part-time modeler, and some compute or test time, which $175,000 struggled to do. But the odds per submission tighten, and they were never generous.

This is the honest limit on the opportunity. NIAC Phase I is not a revenue event. At $225,000 over nine months it is a funded feasibility study — closer to a well-paid research fellowship for your company than to a development contract. Founders who need to clear payroll in Q1 should read the Phase I calendar carefully: Step A closes this month, but money does not move until roughly July 2027. That is a nine-month gap between the deadline and the first drawdown.

TRL 2 or Lower Is a Gate, Not a Preference

The most common way small companies waste a NIAC submission is pitching something that works. The solicitation targets concepts at Technology Readiness Level 2 or lower, and it is explicit that proposals which merely refine or extend current technology, or which lack a clearly defined mission context, are out of scope.

NASA's own language on the 2026 selections frames the bar. Greg Stover, who directs the Advanced Research and Technology division, said the agency's goals "will require more than incremental technological advancement. It means we need great leaps." Phillip Williams, the NIAC acting program executive, described the program's function as germinating seeds: "The NIAC program allows NASA to germinate those seeds and determine if there's something that could be grown to benefit future space missions."

Read as proposal guidance, that is a two-part test. First, the concept has to be a different approach to a known aerospace problem, not a better version of the current approach. Second — and this is where technically strong submissions die — it has to be anchored to a mission NASA can picture. A novel actuator is not a NIAC concept. A novel actuator that makes a specific Venus surface mission survivable for 60 days is.

If you already have a working prototype, a TRL 4 subsystem, and a customer, you are in SBIR territory, not NIAC territory. That is not a downgrade; it is a different instrument. Plenty of aerospace founders should be reading NASA's SBIR solicitation instead, and the sequencing logic is the same one that governs every Phase I-to-Phase II federal ladder — the kind of same-topic, same-window arithmetic we broke down in our analysis of USDA NIFA's 50% Phase II funding rate. Pick the instrument that matches your actual readiness level, then plan the next rung.

Zeno Power and Orbital Velocity Are the Proof of Concept for Small Firms

The skeptical read on "all categories of U.S. organizations" is that the panel still funds JPL and MIT. The 2026 cohort partly supports that — NASA centers and universities took most of the 18 slots. But two selections last cycle came from exactly the kind of company this solicitation's eligibility language invites.

A.C. Charania at Zeno Power Systems, Inc. in Washington, D.C. won a Phase I for EARENDIL, a concept integrating radioisotope heat sources into astronaut suits for operations in lunar night and deep-space icy terrain. Jeffrey Nosanov at Orbital Velocity, LLC in Decatur, Georgia won one for OBLIVION, observing black hole light via intensity correlation. Zeno is a venture-backed power company; Orbital Velocity is a small firm. Neither needed a prime contractor to sponsor the idea, and neither had to route the proposal through a university's office of sponsored research.

That is the structural fact worth internalizing. NASA runs very few programs where a founder's name can appear as Principal Investigator on an agency award without institutional cover. NIAC is one of them. The downstream value is also real: a NIAC Fellowship on the company's record is credibility that survives contact with program managers, and Phase I awardees compete for Phase II, which extends selected concepts over two years at substantially larger dollars — recent cycles have run in the $600,000 to $750,000 range. Phase III sits above that at up to $2 million for a maximum of one new award per year over two years. The Phase I-to-Phase II transition has historically converted somewhere in the 25% to 30% band, which is a far better conditional probability than the initial Step A round.

What to Do Before 5:00 p.m. Eastern on October 28

The work between now and the deadline is small and sequential, and most of it is not writing.

Register in NSPIRES first if you have not. The portal requires both an individual account and an organizational affiliation, and the organizational side is where small companies lose two or three days they did not budget. NASA's help desk is nspires-help@nasaprs.com or (202) 479-9376, weekdays 8 a.m. to 6 p.m. Eastern. Do this today, not on October 27.

Then pull the October 7 Proposers' Forum materials and the FAQ from the NSPIRES page for NNH26ZTR001N-27NIAC_A1. NIAC's review is unusually sensitive to whether proposers understood the scope boundary, and the forum is where the program office says out loud what it will reject.

Then write the three pages against the two-part test: a fundamentally different approach, tied to a nameable mission. Lead with the mission consequence, not the physics. The reviewer needs to know in the first paragraph what becomes possible that is impossible today.

One more thing worth doing while the Step A window is open: NIAC is a nine-month-to-award instrument, which means it should not be your only live application this quarter. If your technology is further along than TRL 2, or you need capital before July 2027, pair this with a near-term solicitation. Search active SBIR Phase I opportunities across NASA and the other agencies on Granted and build the stack deliberately — one visionary-concept grant with a long fuse, one development award that pays this fiscal year.

Step A closes October 28, 2026, at 5:00 p.m. Eastern. Three pages. No prime required.
