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.
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
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.

Migrated from Ruby on Rails to Elixir.
Real-time communication at unprecedented scale.
Migrated from Rails monolith to Elixir microservices.
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.
The pattern is the same every time: fewer servers, smaller teams, lower costs, better uptime.
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.
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.
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.
Top 20 Elixir Influencer
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.
