Product Management Fellow

The Short Version

You're the translator between what a founder dreams, what a user needs, and what can actually be built before the money runs out. That three-way negotiation is the entire job.

What Liminal Is

A Founders Studio. We co-build with repeat founders, many of them unicorn founders, providing build expertise, capital, and unfair access from founding to Series B. We call ourselves a Founders Studio because venture studio undersells what we do and oversells what most of them deliver.

What This Role Actually Is

Product management is the discipline of making the right bets under radical uncertainty and then shipping them. You'll work across our ventures from the earliest moments: when there's no product, no users, no data, and a founder with a conviction about a problem the world doesn't fully understand yet. Your job is to turn that conviction into something people can use, pay for, and rely on.

You need to be fluent in three languages simultaneously: what users actually need versus what they say they need, what's technically feasible versus what the pitch deck promises, and what the business can sustain versus what the founder dreams about at 2 am. Most PMs are passable in one, conversational in two, and fraudulent in the third. We want all three.

The Work

• Research and discovery. Deep market research, user interviews, competitive analysis, and technology landscape mapping. Not the kind that confirms what everyone already believes – the kind that surfaces non-obvious insights and reframes the problem space entirely.
• Product vision and ideation. Work with founders to shape product direction: features, value propositions, roadmaps. You take a founder's sprawling whiteboard session and turn it into a scoped, sequenced plan with clear trade-offs articulated.
• Validation and experimentation. Prototype, test, and iterate. Run experiments with real users. Kill beloved ideas when the evidence says so – with data and surgical diplomacy, not opinion. Saying no to a founder's favorite feature without getting fired is an underrated PM skill.
• MVP build and launch. Coordinate with engineering and design to scope, build, and ship. You own the connective tissue between vision and execution; if something falls through the cracks, it was your crack.
• AI fluency. Actively curious about how AI tools reshape product development: from research synthesis to prototyping to user testing. Not as a resume line. As a practical lens you apply daily.

Who You Are

• Structured thinking under ambiguity. You decompose ill-defined problems into testable hypotheses and clear next steps. Frameworks are tools, not crutches. No existing product. No usage data. No just iterate on the last version. A founder with a world-changing obsession and a blank Figma file. That should thrill you, not paralyze you.
• Real analytical chops. Spreadsheet-brained enough to model trade-offs and interrogate data without fooling yourself. You know the difference between a metric that matters and a vanity number that looks good in a slide.
• User empathy without user worship. What people say, what they do, and what they need are three different data sets. You triangulate across all three.
• Sharp communication. A tight one-pager beats a sprawling PRD every time. You can explain the same trade-off to a founder, an engineer, and an investor in three different ways, each calibrated to what they actually care about.
• Contrarian streak. Independent thinker. Arguments from first principles. Unafraid of unpopular positions: including telling a founder their roadmap is wrong. You believe the best products emerge from open debate. You know how to disagree and commit.

Unicorn Points If

You came to Product through an unusual door. An ER nurse who built a triage app because the hospital's system was broken. A PhD dropout who'd rather ship imperfect solutions to real problems than write perfect papers about theoretical ones. A founder whose first company didn't work out but who learned more about product-market fit from that failure than most PMs learn in a decade. Tell us the story. We'll notice.

Fellowship, Not Internship

Twelve months. Meaningful stipend. Embedded in core projects alongside experienced builders, shipping real products for real ventures, not running hypothetical exercises or writing practice PRDs. If you want to learn product management by actually doing it at the zero-to-one stage where every decision is consequential, this is the door.
