Apparatus 303 — Custom Development
What you know should be worth more than what you charge for it.
We build custom AI tools for consultancies, law firms, and advisory practices - systems that run the work your firm knows how to do, without needing a senior person to do it manually every time.
The Problem
The firms pulling ahead have built things their competitors don't have.
Large AI consultancies charge $500k and up and are built for enterprises ten times your size. The scope is wrong, the process is wrong, and the output doesn't fit the way your firm actually works.
Freelance developers can write code but don't understand the work your firm does. They build what you describe. They can't tell you what you're missing, and they can't test it against work that looks like yours.
Most engagements produce something that works in a demo and breaks in practice. The real constraint - the moment it needs to handle an edge case from actual client work - is where generic solutions fall apart.
You have the expertise. You have been doing this work for years. You know exactly what good output looks like. You just can't turn that knowledge into a system on your own, and every month you don't, someone in your space gets a little further ahead.
Why Apparatus
We run our own firm on the systems we build.
Apparatus is not a software shop that learned about professional services. We work with consultancies, law firms, and advisory practices because that is the kind of firm we run. The tools we sell started as tools we built because nothing on the market did what we needed.
Codex
Built because our onboarding kept depending on whoever had time to run it. It delivers scenario-based questions about your SOPs to your team via Slack or email, tracks who knows what, and flags where the gaps are. Nobody has to run a training session.
Authentic
Built because every CRM assumed we had thousands of leads and wanted to automate follow-up. We had about 100 relationships that actually mattered. Authentic tracks the details that make outreach feel human and tells you when and why to reach out. It suggests. It never sends.
What to Expect
How a 303 engagement works.
01
Discovery.
We spend time understanding your highest-value workflows and where the real constraint is. We are not looking for the most technically interesting problem. We are looking for the one that pays off fastest.
02
Build.
You are involved throughout - this is not a handoff. We test against real work from your firm. When something does not work the way you need it to, we find out before you deploy it, not after.
03
Hand off.
Your environment, your documentation, your system. You own what we build. No ongoing dependency on us unless you want it.
Get Started
Start a project conversation.
303 engagements are scoped individually. The conversation starts with what you are trying to build and whether we are the right people to build it.
Why Now
What happens if you wait.
Firms that build first will have something to defend. They will offer services competitors cannot match because competitors don't have what's running underneath. Firms that wait end up buying the same tools everyone else bought. The window to build something that matters is open now. It won't stay open.
The Other Side
What your firm looks like when the system is running.
You take on work your current team could not have handled before. Capacity expands without adding headcount.
Clients renew because the tool keeps delivering, not just because they like working with you. The value is structural.
Junior staff produce output that used to require a senior person in the room. Senior staff work on what actually requires them.
You built something. It runs without you. That's the difference.

Power Tools
Individual workflows become firm-level assets. Internal data gets connected. What one person knows becomes infrastructure everyone can use.
