Interim product manager for seed-stage startups

Full-time product cover for the months between founder-led product and your first real PM hire — from someone who has run that exact stage twice as a founder.

There's a dangerous stretch in every seed-stage company: the founder can no longer do product justice, the first PM hire is months away, and meanwhile the roadmap is being set by whoever spoke last. An interim product manager exists for exactly that stretch — senior enough to run product alone, temporary by design, and motivated to make themselves replaceable.

Why a founder-turned-PM for this role

I've co-founded two companies and run product at both from day zero. At Medzin I took a healthcare discovery platform from idea to 18,000+ users and Rs. 60L ARR, raising $150,000 in seed capital along the way. At WisOwl AI I'm doing it again in agentic hiring — 5,000+ signups, 15+ recruiter partnerships, zero paid marketing. Between the two I spent eight years at CaaStle running growth product at $30–50M ARR scale, so I also know what your product practices need to grow into.

Seed stage is not miniature enterprise product management. Speed is the strategy: shipping early and iterating against real user behavior beats months of planning in a silo every time. An interim PM who imposes heavyweight process on a ten-person company does damage. What you need is somebody who keeps the feedback loop tight while quietly installing just enough structure — a decision log, a weekly priority call, honest metrics — that the next PM inherits a functioning system.

What the engagement covers

  • Owning the roadmap, specs, and sprint priorities end to end, full-time or near-full-time.
  • Talking to users every week and turning it into decisions the same week.
  • Defining the metrics that matter at your stage and wiring up the instrumentation.
  • Running the search for your permanent PM: scorecard, interviews, and a real handover.

Typical duration is three to six months. The explicit goal from day one is to no longer be needed.

Frequently asked questions

How is interim different from fractional?
Interim is full-time cover for a defined gap — usually until a permanent hire starts. Fractional is ongoing part-time leadership. If product is currently unowned or the owner just left, you want interim.
Can you start quickly?
Yes — interim situations are usually urgent, and I can typically start within a week or two of a signed scope. The first week is spent with users, the data, and the backlog, in that order.
Will you help hire our permanent PM?
It's built into the engagement: role definition, scorecard, sourcing input, interviews, and a proper handover period once they sign. Having hired and been a PM, I know what the good ones look like at seed stage.
What does a seed-stage startup actually get in month one?
A ruthlessly short roadmap tied to your runway, instrumentation for the three metrics that matter, a weekly user-call habit, and usually one painful-but-necessary decision the team had been avoiding.
