Agentic Replatforming for Software Companies

The rewrite, without the two-year detour.

Merven rebuilds your product on a modern stack, keeping the features that earn revenue, dropping the ones that don't, and delivering in a fraction of the time your team could. Your roadmap doesn't stop. Your customers don't notice. You get the codebase you'd build today if you were starting fresh.

Built by engineers with over 5 exits in Fintech, Healthtech, and Martech.

The Problem

Every software company has a rewrite waiting. Almost none of them survive it.

You know the shape of it. The framework two majors behind. The architecture chosen when you were ten engineers, not ninety. The feature surface that grew faster than the foundation. The competitor that just launched on a stack you can't match.

You also know what happens when you try to fix it. The 18-month plan that becomes 30. The parallel build that drifts from production. The senior engineers pulled off the roadmap. The board meeting where someone asks why velocity is down. Most rewrites don't fail because the team is bad. They fail because rewriting and shipping at the same time is brutally hard.

Merven exists for exactly that gap. We rebuild your product on a modern stack while your team stays on the roadmap, and we ship in months, not years.

What We Do

Selective rebuild. Not lift-and-shift.

A bad rewrite copies everything. A good rewrite copies what works.

Our agents read your existing codebase, talk to your team, and decide, feature by feature, what carries forward, what gets simplified, and what doesn't deserve a second life. The new product is leaner, cleaner, and built on the stack you'd choose today, not the one you inherited.

You stay in control of every call. We just do the work.

How It Works

Four Phases. One Continuous Cycle.

From a free audit to an ongoing managed service. You stay in control at every gate.

01

Audit

Understand what you have

Agents crawl your repos, runtime, and traffic to build a Digital Twin of your product: every feature, who uses it, what it depends on, what it costs to maintain. Delivered in under a week. Free.

02

Blueprint

Decide what's worth rebuilding

A feature-by-feature triage: keep, simplify, drop. Target stack proposed (Node, Python, Go, modern frontend frameworks; your call). Migration plan scoped with real dates. Your team approves before a line of new code is written. Already have a stack in mind? We're framework agnostic.

Rebuild

Ship the new product

Specialized agents handle the work in parallel: service extraction, schema migration, API rebuild, frontend reconstruction, test generation. Customers don't notice. Your team reviews and merges.

Manage

Keep it modern, forever

Optional ongoing service: dependency upgrades, security patches, performance regressions, framework migrations. The codebase you just got never has to age again.

Why Merven

Built for the rebuild your team doesn't have time to do.

Faster than your team can do it

Agents work in parallel across the codebase. What takes a team of ten a year takes us a quarter.

Your roadmap keeps shipping

We carry the rebuild. Your engineers stay on product. No frozen sprints, no morale tax.

Your stack, your call

We rebuild on the modern stack you want, not the one we're locked into. Cloud-agnostic, framework-agnostic.

Proven features only

AI-driven feature triage means you don't pay to rebuild things nobody uses.

Reversible cutover

Old and new run in parallel until you say go. One-click rollback if anything looks wrong.

You own everything

Your code, your IP, your repo. We don't train on it. We don't lock you in.
