Technical or domain depth
Founders who know something about their problem that the market hasn't priced yet.
Early-stage AI
We back the software layers of the AI stack.
Supra is an early-stage firm investing at pre-seed and seed in AI infrastructure, tooling, agents, and vertical applications. We write early checks and move at the speed the round demands.
Thesis
Value accrues in layers. We invest where our experience is.
- 06Applications and vertical AI
- 05Agents, orchestration, workflow
- 04Data, retrieval, developer tooling
- 03Models and model tooling
- 02Infrastructure and inference
- 01Compute and hardware — watched, not underwritten
We follow a layered reading of the AI stack. We study the whole value chain, then concentrate in the software layers where we have built, shipped, and hired — layers two through six.
Silicon and hardware we watch rather than underwrite: longer cycles, heavier capital, richer early pricing.
The question we ask
What breaks if a foundation model ships this natively? If nothing does, we keep listening.
Founders
What earns an early check
A defensible wedge
Something hard to copy — data, workflow depth, distribution, or genuine engineering difficulty.
A market that is expanding
Categories being redrawn by AI rather than incrementally improved by it.
How we work
- A first conversation, usually within a week of reaching out.
- A technical read: architecture, model dependency, inference economics.
- References through operators who have worked with you.
- A decision. Typically two weeks from first call, and a clear no if it's a no.
No warm intro required. A short note about what you’re building is enough.

Questions
Common questions
What stage does Supra invest at?
Supra invests at pre-seed and seed. We write early checks and move at the speed the round demands.
What does Supra invest in?
The software layers of the AI stack: infrastructure and inference, models and model tooling, data, retrieval and developer tooling, agents, orchestration and workflow, and applications and vertical AI. We watch compute and hardware rather than underwrite them.
Do you need a warm introduction to reach Supra?
No. A short note about what you are building is enough. Every note sent through the site is read and answered either way.
How long does Supra take to make a decision?
Typically two weeks from the first call, and a clear no if it is a no. The first conversation usually happens within a week of reaching out.
What does Supra look for in a founder?
Technical or domain depth, a defensible wedge that is hard to copy, and a market being redrawn by AI rather than incrementally improved by it.
Where is Supra based?
The San Francisco Bay Area. Supra can be reached at [email protected].
