About Cosmerg

We help builders get their products into orbit.

AI made it possible for anyone to build an app in a weekend. Getting that app safely in front of real users is still hard. Cosmerg exists to close that gap.

The name

cosmos /ˈkɒz.mɒs/

Every product starts as scattered matter: an idea, a prototype, a pile of AI-generated code, a dozen half-connected services. Full of possibility, not yet stable.

merge /mɜːdʒ/

Bringing it together into one working system, and the developer's merge: the reviewed, tested change that makes it into production. That's our job.

Why we exist

The gap between a demo and a product.

Tools like Lovable, Bolt, Replit, and Cursor changed who gets to build software. Founders who once needed a technical co-founder can now ship a working prototype on their own. That's a good thing, and we're here for it.

But the prototype is only the start. Real users bring real risks: leaked keys, open databases, broken payments, and bills that spike overnight. Traditional agencies are too slow and too expensive for this stage. Doing it alone means learning security and infrastructure the hard way.

Cosmerg sits in that gap. We take what you built, or what you want to build, and make it production-grade, quickly and at a price that makes sense for an early-stage company.

Our vision

Production-grade software for every builder.

Five promises we make to every client, whether they bring code, an idea, or a legacy system.

  • Early

    Production in days, an MVP in weeks. Fixed timelines on every package.

  • Affordable

    A fixed quote agreed before we start. No open-ended hourly billing.

  • Optimised

    Fast pages, lean queries, and hosting and API bills sized to your stage.

  • Low tech debt

    Typed, tested, documented code in your repo. You own all of it.

  • Secure

    Every project passes the Cosmerg Security Standard before it ships.

How we use AI

AI-accelerated. Engineer-owned.

We build with the same AI tools as our clients. The difference is who's accountable for what ships.

  • AI for speed

    We use the same AI tools you'd use, so boilerplate and first drafts take hours, not weeks.

  • Engineers for judgment

    Senior engineers own the architecture, review every change, and say no to shortcuts that cost you later.

  • Standards for safety

    Tests, CI, monitoring, and the Cosmerg Security Standard are in from the first commit, not bolted on.

What we believe

Six things that shape every project.

  1. 01

    Ship early, then improve

    Real users teach you more than another month of building. We get you there sooner.

  2. 02

    Security isn't optional at any size

    A ten-user app can still leak ten users' data. The basics apply from day one.

  3. 03

    You should own everything

    Your code, your accounts, your data. If we disappeared tomorrow, you'd lose nothing.

  4. 04

    Boring technology is a feature

    Proven tools are cheaper to run, easier to hire for, and fail in well-understood ways.

  5. 05

    Honest scoping beats big promises

    We'll tell you when something isn't worth building, or when a fix costs more than a rewrite.

  6. 06

    Vibe coding is a superpower

    We're not here to replace it. We're here to make what it creates safe to ship.
