A lot of founders assume NASA money is only for established contractors. Not true — but the entry points are specific, and a couple of them care more about the idea than the org chart.
NASA Innovative Advanced Concepts is the friendliest door for a visionary early team. It funds architecture-level concepts that are years from reality, and individuals as well as companies can win Phase I (~$175K over 9 months). What you need is a genuinely novel, physically credible concept and a clear feasibility question — not a prototype. See NIAC.
Phase I (~$225K) is explicitly for proving feasibility, so a small team with deep technical insight and a plan can compete. The catch: you must be a registered U.S. for-profit small business to receive award, and registration in SAM.gov and NSPIRES takes weeks — start it before the subtopic you want appears.
Idea-stage is exactly when cheap simulation pays off most — kill bad architectures before you build. We can arrange an Ansys evaluation to run those early trade studies.

NASA proposals aren't public marketing, and you can pursue funding while staying quiet commercially. Do incorporate and register early, though — the administrative path is the slow part, not the idea. When you're ready to build, read the full funding map and how to de-risk the physics.
