Solution

Build your MVP

Ship a real product in 8–12 weeks with paying users on it.

An end-to-end MVP build with a senior squad — design, engineering, infra, analytics — focused on getting you to first revenue.

Timeline · 8–12 weeks

Solution

Launch your SaaS

A SaaS platform with billing, RBAC, and an admin console — ready for paying customers.

We turn your tool into a SaaS: tenants modeled correctly, billing wired to Stripe, ops console for your team, audit trail for your customers.

Timeline · 10–20 weeks

Solution

Modernize your system

A modern, typed, observable system the team is fast in again.

We migrate legacy systems incrementally — strangler-fig, not big-bang — so you keep shipping while the foundation rebuilds itself underneath.

Timeline · 12–24 weeks

Solution

Scale your backend

A backend that handles 10x without 10x cost or 10x pain.

We profile, redesign, and re-architect the parts that hurt — caching, queues, sharding, edge — measured against your real workload.

Timeline · 6–14 weeks

Selected work

The projects we'd want you to ask about.

Each engagement is measured by the same thing: did it ship, did it scale, did the team keep building.

How we work

Discover. Build. Scale.

No discovery decks that go nowhere. We pick a scope, ship in two-week sprints, and leave you operating it.

Discover

Two weeks to align on outcome, scope, and timeline. Out: a written brief, a roadmap, and a fixed price.

Build

Senior squads ship in two-week sprints. Working software every Friday. Demos, not status updates.

Scale

We leave you with a codebase your team is proud to inherit, runbooks they'll actually open, and a path to v2.

Why teams pick Primeline

Senior people. Boring tools. Ambitious products.

Primeline is built around a simple bet: the right senior team, with the right scope, ships products that compound. Not throwaway demos. Not consulting decks. Software your customers can pay for.

Tech lead with 8+ years on every engagement
Two-week sprints, working software every Friday
Fixed-price engagements with no hidden hours
Codebase your team is proud to inherit
Stripe billing, RBAC, observability — wired from day one
Documentation written for engineers, not for compliance
