Roster open · Q3 intakeA senior product practice for seed-stage founders

Three senior minds. One product foundation.

Threewise embeds three senior product, UX, and design partners into your earliest stage — defining the architecture, shipping the MVP, and building the product muscle your team will eventually run on its own.

(01)Position

Most startups don't need another design vendor. They need the senior product layer they can't hire yet — and the discipline to outgrow it.

What goes wrong

Founders ship screens before architecture. Hire too early, or hire wrong. Burn the first eighteen months on a product that can't hold a Series A.

What we do instead

We sit beside three founders at a time, define the product foundation alongside them, and stay long enough to leave it standing — then hand the baton to the team they've grown.

(02)Selected work

Three foundations, built with founders.

A short list, on purpose. Each engagement ran long enough to leave a product the team could keep building on — and a senior practice they could keep operating.

(03)About us

Three partners. One practice.

No account layer, no junior production team handed off behind the scenes. You work with the three of us, every week, for as long as the engagement runs. Combined, we've shipped product at every stage from pre-seed to public — and we've built the practice we wish we'd had access to as founders.

(04)Practice

Six disciplines. One embedded team.

We don't sell deliverables in a deck. We bring the practice of a senior product organization to a stage of company that shouldn't have to build one yet.

i.

Product architecture

The bones underneath the screens. Object models, primitives, surface hierarchy, naming. Where founder-led decisions become a system other people can build on.

ii.

UX strategy

User behavior, market frame, and the smallest set of decisions that move you from a story to a defensible product shape. We pressure-test the thesis before anyone draws a screen.

iii.

MVP design & creation

Scope you can actually ship in a quarter — wireframes, core flows, dev-ready handoff. No fidelity theatre, no scope creep, no abandoned half-features.

iv.

Design systems

Tokens, primitives, a component library, and the documentation that makes them durable. Built to grow with the product, not paved over at Series A.

v.

AI-accelerated execution

Wireframes, inside pages, system mapping, spec drafts, content scaffolds — the production layer is AI-assisted. The judgment layer is human, senior, and ours.

vi.

Embedded operating system

Founder discovery, weekly product reviews, roadmap pressure-testing, hiring support. A repeatable cadence that turns the three of us into a senior product team you operate with.

(05)The Glide Process

An exit that feels like a relay, not a farewell.

We stay with one founder for six to twelve months — long enough to define the product, mature the practice, and hand the baton to the team they grew on the way.

Threewise ownershipFounder / internal teamScroll to advance the timeline

  1. 01

    Discovery

    Founder workshops, user behavior, product thesis. We pressure-test before anyone opens Figma.

  2. 02

    Architecture

    Product surface, object model, MVP scope. The bones go in before the skin.

  3. 03

    MVP shipped

    Core flows, design system v1, dev-ready handoff.

  4. 04

    Iteration

    User feedback, scaling the surface. Roadmap pressure-tested weekly.

  5. 05

    First hires

    We help recruit the first product designer, PM, or systems lead.

  6. 06

    Handoff

    Knowledge, documentation, decision-making transfer to your internal team.

(06)Why three

One hire is a single lens. Three is a practice.

Seed-stage founders can't afford to hire one excellent senior — let alone three. So they hire one generalist and call it product. We bring three lenses at the price of one hire, and the discipline of a senior org that doesn't exist yet.

  1. I.

    Architecture

    The product systems lens. Object models, surface, naming, primitives — the bones underneath what users see.

  2. II.

    Behavior

    The user lens. Psychology, motivation, how humans actually move through software — and what makes them stay.

  3. III.

    Execution

    The craft lens. Design systems, AI-accelerated production, the discipline of shipping fast without losing taste.

(07)Services

Bring us a company — or bring us a problem.

Two tracks, one practice. A partnership takes a seat for six to twelve months; a project takes the same seat for a few weeks. Four to five seats at a time — no more — so both get the same three partners, at the same standard.

Track 01

The Partnership

Every partnership starts with the same founder session; what comes after depends on what your product actually needs.

Audit

Two weeks
$18kfixed scope

A senior product audit and strategy memo. Architecture, surface, MVP scope, and a written read on what to build, hire, and abandon.

  • Founder discovery session
  • Architecture & surface review
  • MVP scope memo + handoff
  • Two-week turnaround
Start here →

MVP

10–14 weeks
$55–95kmilestone-based

We define and ship the MVP with you — architecture, flows, design system v1, dev-ready handoff. A product founders can put in front of users and capital.

  • Product architecture & object model
  • Wireframes through final design
  • Design system v1
  • Dev-ready handoff + spec
Start here →
Flagship

Embedded

6–12 months
$15–20k/mo+ 2–3% equity

The Glide Process in full. Three senior product partners embedded, AI-accelerated execution, weekly product reviews, hiring support, and an exit that hands the practice to your internal team.

  • Three senior partners embedded
  • Weekly product cadence & reviews
  • Hiring & onboarding for your team
  • Glide path to internal product org

Track 02

Projects

For funded teams with product and design in-house who need senior firepower on a single surface. Fixed scope, no retainer — you bring the problem, we bring the practice.

  • 01

    Flow rebuild

    One critical journey — onboarding, activation, checkout — torn down and reshipped.

    ~3–4 weeks
  • 02

    Concept sprint

    A new product idea made tangible: pitch-ready prototype, plus the thinking behind it.

    ~2–3 weeks
  • 03

    Design-system intervention

    Tokens, components, and the discipline to keep them. For UIs that have drifted.

    ~3–4 weeks
  • 04

    AI surface sprint

    The AI layer inside your product, designed like a product — not a chatbox bolted on.

    ~3–4 weeks

Book a founder session.

Ninety minutes with the three of us. Bring the product idea, the hires you're weighing, and the open questions. You'll leave with a written read on architecture, scope, and the cleanest path to your MVP — whether or not we end up working together.
