We've never used Elixir. Isn't that risky?

The Erlang VM that powers Elixir has been running telecom infrastructure for 30+ years — systems that require 99.999% uptime. Discord, Pinterest, PepsiCo, and Brex all run on it. The risk isn't Elixir. The risk is staying on a stack that costs you 3x more to maintain and scale.

Can our Ruby/Python developers learn Elixir?

Fresha migrated their entire Ruby team to Elixir with zero attrition. Elixir's creator, José Valim, came from the Ruby community. Most Ruby developers become productive in Elixir within 2–4 weeks. We include team training in every engagement.

What if the migration fails or takes too long?

We use the strangler pattern — migrating service by service while your product stays live. There is no big-bang switchover. If you decide to stop after migrating 3 out of 10 services, those 3 services are already saving you money. Every step delivers standalone value.

Why not just optimize our current Rails/Node app?

You can. And for some companies that's the right call. That's exactly what the paid assessment determines — whether migration makes financial sense for your specific situation. We'll tell you if it doesn't.

How much does it cost?

Assessments are billed per hour — a full codebase audit with migration roadmap. Full engagements are scoped and priced after the assessment. We'll give you a precise estimate once we understand your codebase.

We're a small team. Can you just build the whole thing?

Yes. For funded startups building V1, we provide full-cycle delivery — from architecture to deployment. You get a production-ready Elixir/Phoenix application and the knowledge to maintain it.

Your backend is slowing you down.
We fix that.

We've scaled platforms handling millions of operations and managed €10M+ tech budgets. Now we help growth-stage companies rebuild their backend on Elixir cutting infrastructure costs in half and shipping 3x faster with smaller teams.

What We Do

Two Ways to Win

Build From Scratch

You raised money. You need a product that won't break when you scale.

We've built platforms that handle millions of operations. Now we help funded startups skip the "rebuild everything at Series B" trap by building on Elixir/Phoenix from day one.

What you get: Architecture → Development → Deployment → Handoff to your team.

Let's Talk Architecture

Rewrite & Migration

Your Rails/Node app worked at 1,000 users. At 100,000 it's falling apart.

We've done this migration at scale, in production, with zero downtime. We help companies move from legacy stacks to Elixir, typically cutting server costs 30–50% and reducing backend team size from 8–10 to 3–4 engineers.

What you get: Codebase audit → Migration roadmap → Phased execution → Your team trained on Elixir.

Results

What Elixir Changes For Your Business

These aren't hypothetical. These are documented results from companies that made the switch.

Bleacher Report

Migrated from Ruby on Rails to Elixir.

Server fleet: 150 → 5 Traffic capacity: 8x increase

Discord

Real-time communication at unprecedented scale.

11M concurrent users 5M events/second

Fresha (ex-Shedul)

Migrated from Rails monolith to Elixir microservices.

Ruby devs retrained in weeks Zero attrition

What I Built

Scaled a European logistics platform to millions of shipments across 30+ countries. Managed €10M+ technology budget and 50+ engineer organization. Built the architecture that the company still runs on today.

Millions of shipments 50+ engineers managed

The pattern is the same every time: fewer servers, smaller teams, lower costs, better uptime.

Process

How an Engagement Works

Typically 1–2 Weeks

Assessment

We audit your current codebase, infrastructure costs, and team structure. You get a document with: what to migrate first, expected savings, timeline, and risks.

Billed per hour. No commitment beyond this.

Varies by Scope

Execution

Our team migrates your highest-impact services first using the strangler pattern your product stays live, your users notice nothing. You start seeing infrastructure savings from month 2.

Your product stays live throughout.

Ongoing

Handoff & Training

We train your existing developers on Elixir (especially easy for Ruby/Python devs). You own everything. No vendor lock-in. No retainer trap.

You own 100% of the code and knowledge.

About

I spent 10 years building software products, including scaling a major European logistics platform to millions of shipments managing a €10M+ technology budget and a 50+ engineer organization.

We've seen what happens when companies pick the wrong stack early: endless hiring, exploding AWS bills, and a codebase nobody wants to touch.

I started 1703 Group to fix exactly that. I work with a small, senior team no juniors, no bench, no overhead. You get the same person on the call and in the code.

Based in Luxembourg. Working globally.
