WE BUILD
COMPANIES
before they exist.
Zero to shipped product in weeks. Built with the speed of a founding team, not the drag of a vendor.
Most products die in the gap between the idea and the first user.
We exist to close that gap — with conviction, velocity, and an unreasonable standard for craft.
Posterity is not an agency. We operate like the founding team of each product we touch — making the calls a founder would make, cutting what doesn't matter, and shipping what does.
Founding MVPs
The first shippable version of an ambitious idea — scoped ruthlessly, built to earn its next round.
AI-native products
Products designed around models from day one — not features bolted onto yesterday's software.
Zero-to-one platforms
New markets need new machines. We build the infrastructure your category doesn't have yet.
Brand & launch systems
Identity, story, and site — engineered as one motion so the product arrives like it means it.
Six weeks. One team. No drift.
Days 1–5
01
Shape
One week to strip the idea to its sharpest form. Positioning, scope, and the single bet the MVP must win.
Weeks 2–5
02
Build
A senior product team in full sprint. Design and engineering move as one — no handoffs, no tickets, no drift.
Week 6
03
Launch
Brand, site, and product land together. Your first users arrive at something that feels inevitable.
Ongoing
04
Compound
We stay in the loop as the product meets reality — instrumenting, iterating, and preparing the next raise.
You are not hiring a vendor. You are borrowing a founding team.
Founder judgment
Every decision is made the way an owner would make it — scope, taste, and trade-offs included.
Startup metabolism
Weekly ships, daily decisions. The cadence of a seed-stage team, not a services firm.
Craft as strategy
In a world of generated sameness, taste is the last unfair advantage. We treat it as one.
05 — The invitation
BUILD WHAT
outlives you.
Two builds per quarter. One might be yours.
