Eterna

Custom software studio

Custom software for companies that have outgrown off-the-shelf tools.

Eterna is a founder-led studio. We design, build and maintain web platforms, internal tools and AI-assisted systems. A founder leads every project, and the engineers who scope the work are the ones who build it.

(01)Why Eterna

Most software projects go wrong in the handoffs: from sales to engineering, from the agency to your team. We removed the handoffs.

Built to stay standing
  • 01

    A founder on every project

    There is no sales layer and no handoff. A founder scopes your project, leads it through delivery with our own engineers, and answers the phone after launch.

  • 02

    Weekly, visible progress

    Every week you get a working build on a staging environment and a short written update. Nothing waits until the end.

  • 03

    Built to be maintained

    Plain architecture, tests, documentation and your own cloud accounts. You could hand the code to any competent team, including one that is not us.

(02)Services

Seven services. One team across all of them.

Every engagement is led by a founder and staffed from our own team of engineers and designers. No subcontracting, no rotating cast, and the same people from kickoff to launch.

  • The internal tools, platforms and back-office systems your business runs on, built from scratch or on top of what you already have.

    • Requirements workshops and technical scoping
    • Architecture, data modelling and API design
    • Backend and frontend implementation
    • Integrations with CRM, ERP, payments and identity providers
    • Automated tests and a documented handover

(03)Selected work

Teams we have built for.

A founder led each of these projects from the first call to launch, working directly with the client's own team.

  • 01

    Kumo AI

    Now part of NVIDIA

    AI models for relational data

    We designed and built the web workspace where data teams connect their tables, set up predictions and review model results, working alongside Kumo's platform engineers from first prototype to launch.

  • 02

    CoreStack

    Cloud, SaaS and AI governance

    We built customer-facing dashboards that pull cost, security and compliance findings from many cloud accounts into one view, and automated the reports their customers used to put together by hand.

  • 04

    Coach

    Gamified microlearning

    We built the mobile app where employees learn through short, game-style lessons, and the admin panel where managers assign training and follow their team's progress.

(04)How we work

A process you can see from the outside.

Four stages, each with a concrete output. You always know what has been done, what is next and what it costs.

  1. 011 to 2 weeks

    Discovery

    We map the problem, the users and the constraints. You get a written scope, an architecture outline and a fixed quote.

  2. 021 to 3 weeks

    Design

    Flows and interfaces first, as clickable prototypes, so you can react to something real before we write application code.

  3. 03Weekly releases

    Build

    Working software on a staging environment every week. You test as we go, and priorities can change between iterations.

  4. 04Ongoing

    Launch and run

    We deploy to your infrastructure, set up monitoring and hand over documentation. Many clients keep us on a retainer.

(05)About us

Three founders, a senior team, and no layers in between.

We started Eterna after years of watching good projects fail in the gaps between sales, project management and engineering. So we built a studio without the gaps: a founder leads every project, and the team that scopes it is the team that ships it.

(06)Testimonials

What clients say after launch.

“They replaced a process that lived in four spreadsheets with one system our whole team uses daily. Ten weeks from first call to launch, and it has run without incident since.”
