02 · The Builder Arm

Stealth
Incubator.

12-week cycles · Zero to revenue · Concept to round

We don't accelerate. We don't advise. We build. Founders bring a problem, we bring product, engineering, design, GTM, and operating capital. 12 weeks later there's a company in market with revenue and a pre-committed seed round.

What we build

We build the companies most VCs won't fund yet.

01 · Pre-product

Idea + founder + nothing else. The conversation that starts with "I have this thesis but no demo" — that's where we live. We build the demo. We build the wedge. We get to first revenue.

02 · AI-native by default

Every company we build is AI at the core, not bolted on the side. If it could be built without AI, it doesn't belong here. Our internal stack — models, infra, evals — is shared across every cohort.

03 · Cofounder-grade equity

We take 30–40% in exchange for the build. You walk in with an idea. You walk out with a company, a cofounder team, working product, real revenue, and a pre-committed seed round from Stealth Ventures.

04 · Graduation = funded

Every graduating Incubator company gets a guaranteed seed term sheet from Stealth Ventures on the way out. No second pitch. No re-diligence. The hard work was the 12 weeks — the check is the reward.

The 12 weeks

Concept → Revenue. 90 days.

Week 1–3

Wedge & spec.

We sharpen the founder's thesis into a wedge. Customer interviews, problem definition, MVP spec, pricing experiment. Engineering kickoff at the end of week 3.

Week 4–7

Build.

Our internal team (3-5 engineers, 1 designer, 1 PM) builds alongside the founder. Daily standups. Weekly demos to the partnership. End of week 7: live product, 5 paying customers.

Week 8–10

Distribute.

Sales hand-off, content engine, partner intros from the network of 600+ portfolio companies. ARR target: $10K MRR by end of week 10. Cofounder candidates interviewed in parallel.

Week 11–12

Graduate.

Seed term sheet signed from Stealth Ventures. Cofounder offer extended. Spinout — the company moves out of our office and into its own legal entity. We become first investor and board observer.

Who qualifies

Three kinds of founders.

01 · The domain expert.

You've worked 5–15 years inside an industry. You see the workflow that AI should obliterate. You have customer access. You don't have engineering, design, or AI/ML talent. We bring all three.

02 · The repeat founder.

You've built and exited before. You want to start the next one without the 18-month pre-seed grind. We compress the pre-seed into 12 weeks and write the first check on graduation day.

03 · The 10x technical founder.

You're an AI/ML researcher, a senior engineer at OpenAI/Anthropic/Google DeepMind, or a top-tier ICPC/Putnam-grade builder. You have technical chops. We bring the product, GTM, and operating chassis.
