// WHY US

Why A Lab, Not An Agency

Traditional agencies sell hours. We ship products — for ourselves and for you.

Traditional Agency

✕ 3-6 months to launch ✕ $50k-$150k+ cost ✕ Offshore teams & handoffs ✕ Scope creep & change orders ✕ No skin in the game

Posterity Labs

✓ 8 weeks to production ✓ Fixed price, no surprises ✓ One team, direct communication ✓ Scope locked before kickoff ✓ We build our own products too
// FAQS

Common Questions

Everything you need to know before starting a project with us.

Most products ship in 56 days — that includes planning, full frontend and backend development, and deploying live. More complex projects with custom AI integrations or marketplace logic may take 9-10 weeks, but we're transparent about timelines from day one during the scoping phase.
We're a venture lab that builds our own products using the same team and process. When you work with us, you get engineers who ship real companies — not just billable hours. Fixed pricing, direct communication with engineers, and daily updates from start to ship.
Our ventures are products we build, own, and operate — like SpawnMail and Saege. Partner builds are products we develop for founders at a fixed price. Same team, same stack, same speed. The difference is ownership.
We build with Next.js, React, TypeScript, Supabase, Tailwind CSS, and deploy to Vercel. For AI features, we integrate OpenAI, Claude, and open-source models. For payments, Stripe. This stack handles SaaS, marketplaces, AI products, and internal tools at production scale.
You get full code ownership with clean documentation and deployment guides. We include 30 days of post-launch support for bug fixes and questions. Need ongoing development? We offer flexible retainer options to keep shipping new features after launch. Many of our partners continue as ongoing ventures in the Posterity Labs portfolio.
No. You bring the vision and market insight. We handle everything technical — from architecture decisions to deployment. You'll get regular updates via Slack and can give feedback at every stage without writing a single line of code.
We'll tell you upfront. During the Discovery Sprint, we scope exactly what fits in 8 weeks and what gets deferred to a V2. Most founders are surprised by how much we can ship when we cut ruthlessly and focus on what matters for validation.
