Raising a seed round in deep tech.
At seed, deep tech investors want a working prototype, an early customer who cares, and a milestone plan that keeps the science on a budget. Here is the bar and who writes the checks.
Deep tech
Deep tech investors judge three things before anything else: a technical breakthrough with a clear path to proof, a plan that turns long R&D timelines into funded milestones, and a market that will pay once the science works.
What seed investors expect in deep tech
Seed in deep tech is judged on three things before anything else. Show each one on a slide of its own.
A prototype that works
- The core technology demonstrated outside the lab bench
- Performance data against the method it replaces
- Known limits and how you plan to fix them
A customer who cares
- Industrial or government partners testing it
- Joint development or paid evaluation agreements
- A first application that can earn revenue soonest
A funded milestone plan
- The technical risks left, in order
- Which milestones this round funds and which grants cover
- A realistic timeline with slack for setbacks

Pre-seed & seed funds
Often leads
Seed funds with technical partners lead most deep tech seed rounds.
Grants & non-dilutive
Often follows
Larger government research grants fund development alongside equity.
Corporate VCs
Sometimes
Industrial and technology companies invest when the work fits their roadmap.
University funds
Sometimes
University funds follow on in their own spinouts.
Family offices
Now and then
Patient family capital can suit long technical timelines.
SAFE or priced round?
Many deep tech seed rounds start on SAFEs, but longer timelines push more of them to priced equity with a board. Check that grant terms and university licenses do not conflict with investor rights.

Questions founders ask
How long a runway do deep tech seed rounds need?
Usually longer than software, because experiments and prototypes take time. Size the round to reach a clear technical milestone with a margin for setbacks, and use the runway calculator to test it.
How do grants and equity fit together at seed?
Grants can fund specific research while equity funds the company. Investors like the leverage, but read grant terms for limits on spending, reporting and ownership of results.
