The Elixir Development Team That José Valim Trusts

Let's talk

The Uncomfortable Truth About Many Elixir Investments

Most Elixir applications run at a fraction of their potential. They're built by teams who learned Elixir syntax but never mastered Elixir thinking. They use GenServers like objects. They fight the actor model instead of embracing it. They scale by adding servers instead of fixing architecture.

You invested in Elixir or are considering to invest in it for its promises: massive concurrency, fault tolerance, incredible efficiency. But without the right expertise, you got Ruby with weird syntax instead.

We've rescued dozens of these systems. We've seen what happens when Rails developers try to write Elixir. We've inherited the technical debt, the memory leaks, the supervision trees that don't supervise.

The question isn't whether you need better Elixir expertise. It's whether you'll get it before your competitors do.

Two Ways We Elevate Your Elixir Capabilities

Path #1

Greenfield Development

Start fresh with Elixir's full potential from day one. Build your MVP in weeks, not months, with a technology stack that scales from prototype to millions of users without rewrites.

Path #2

Augment Your Team with Senior Expertise

Keep your team, add our experience. Our senior Elixir engineers integrate seamlessly, bringing patterns and practices from systems serving millions. We mentor, we build, and we transfer knowledge that levels up your entire organization. We diagnose bottlenecks, refactor problem areas, and implement patterns that unlock Elixir's true potential—often achieving 10x performance gains.

The result:
Elixir applications that actually deliver on the promise of massive scale with minimal resources—not just Elixir in name only.

Why Companies Switch to Appunite

We Wrote the Playbook Others Follow

  • Direct partnership with José Valim on complex implementations
  • Active contributors to Elixir core and key libraries
  • Conference speakers sharing our learnings with the community
  • Open source maintainers of tools many developers use

Proven at Unprecedented Scale

Other agencies might talk about scale. We've actually built it:
  • 16M unique monthly visits on an e-commerce platform with <10 developers
  • 14M users with 400K+ MAU maintained by a team of 4
  • Zero downtime deployments across hundreds of production releases
  • Sub-millisecond response times under massive concurrent load

Beyond Basic Elixir Implementation

Most teams can write Elixir code. Few understand how to:
  • Architect OTP applications for true fault tolerance
  • Implement LiveView at scale without memory bloat
  • Optimize BEAM VM for your specific use case
  • Design supervision trees that self-heal under pressure
  • Build distributed systems that actually stay synchronized

We Fix What Others Can't

We're often called when other Elixir teams hit walls:
  • Memory leaks in GenServers they can't trace
  • LiveView applications crashing under real load
  • Distributed systems losing consistency
  • Phoenix channels dropping connections at scale
  • OTP designs that looked good on paper but fail in production

How We Transform Your Elixir Operations

Week 1: Deep System Audit
We analyze your codebase, architecture, and deployment patterns. You'll receive a detailed report on bottlenecks, anti-patterns, and exactly why you're not seeing Elixir's promised benefits.
Week 2-4: Critical Fixes
We address the top issues killing your performance. Memory leaks, supervision tree problems, deployment issues—fixed by engineers who've seen it all before.
Week 5-8: Architecture Evolution
We refactor core systems using patterns from our million-user deployments. Your application doesn't just run better—it runs like Elixir was meant to run.
Ongoing: Knowledge Transfer
We don't just fix and leave. We document, train, and embed best practices so your team maintains excellence long after our engagement.

Critical Expertise For

CTOs with Elixir Systems whose current team is good but not great, and scale demands excellence
Engineering Leaders who need senior expertise to mentor their team and establish best practices
Product Teams struggling with slow feature delivery despite using "fast" technology
Companies in Transition moving from agencies that treat Elixir like Ruby with different syntax

Not All Elixir Teams Are Created Equal
We've Been Building at Scale Since Day One

When José Valim, Elixir's creator, needs a development partner, he chooses us. Since 2015, we've not only built production Elixir systems—we've contributed to the language and ecosystem itself. We're the team other Elixir developers turn to when they're stuck.

Other Elixir developers may know the language itself. But do they know how to make it serve 14 million users with just 4 developers? Do they contribute to Elixir core? Do they teach at ElixirConf? We do all three.

Your Elixir application deserves developers who contribute to the language itself. Scale faster with the team that's been mastering Elixir since 2015.
