05 / Product Lab

For founders with an idea worth testing.

  • Idea Evaluation
  • MVP Scope
  • Validation Plan
  • Pitch Deck
  • Roadmap

By invitation. We scope, build, validate — and we'll tell you when to pull the plug. No vanity MVPs. No "let's see what happens."

Product Lab service illustration

What's included

Idea evaluation sprint

1–2 week sprint: problem validation, market sizing, go/no-go recommendation.

MVP scoping & roadmap

Ruthless v1 scope, milestones, and build-vs-buy calls.

Validation plan

Landing test, ad test, customer interviews, and success metrics.

Pitch deck

Narrative arc, financial story, and design polish.

Investor materials

One-pager, data room outline, and FAQ.

Co-build engagement

Limited Labs builds the MVP — optional equity or revenue share component.

Founder coaching cadence

Weekly check-ins through the sprint.

Explicit go/no-go decision

Clear recommendation at the end of the validation window — including when to stop.

Who it's for

  • 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.

Deliverables

  • Idea evaluation report
  • MVP scope + roadmap
  • Validation plan with success metrics
  • Pitch deck (if raising)
  • Go/no-go recommendation
  • Co-build proposal (if proceeding)

How we work

01

Evaluate

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

02

Scope & validate

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

03

Build or stop

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