05 / Product Lab

For founders with an idea worth testing.

By invitation. We scope, build, validate — and tell you when to stop.

What's included

01
Idea evaluation sprint
1–2 week sprint: problem validation, market sizing, go/no-go recommendation.
02
MVP scoping & roadmap
Ruthless v1 scope, milestones, and build-vs-buy calls.
03
Validation plan
Landing test, ad test, customer interviews, and success metrics.
04
Pitch deck
Narrative arc, financial story, and design polish.
05
Investor materials
One-pager, data room outline, and FAQ.
06
Co-build engagement
Limited Labs builds the MVP — optional equity or revenue share component.
07
Founder coaching cadence
Weekly check-ins through the sprint.
08
Explicit go/no-go decision
Clear recommendation at the end of the validation window — including when to stop.

Founders with a specific idea and the discipline to test it — not explore forever.
Early-stage operators who need a partner to say no, not just yes.
Teams invited after a discovery call — we don't take every idea.
Anyone who'd rather kill a bad idea fast than fund a vanity MVP for six months.

Problem, market, and feasibility — we stress-test the idea before writing a single line of code.

Ruthless MVP scope and a validation plan with real success metrics — not vanity signups.

Co-build the MVP, hand off to your team, or recommend a clean sunset. We tell you which.

Selective engagement

Product Lab is considered after qualification when we have conviction in the problem. Request a systems audit to share the operating context.

Start with context, not a sales pitch.
