04 · Done-with-you build · 2 to 4 weeks
Stop duct-taping a workflow. Ship a custom GPT that owns it.
A custom GPT that actually solves the workflow you keep duct-taping. Built with you, evaluated on your real cases, and handed over with the prompts and evals so your team can change it without us.

Single focused build. More complex scopes quoted on the call.
2 to 4 weeks to live
You leave with the GPT, the prompts, the evals, and the handover. We are off the build by week four.

How the build runs
Five steps, weeks not quarters
01
Scope the job to be done
We pin down the single workflow this GPT will own. If it cannot be named in one sentence, we cut until it can.
02
Build the GPT
System prompt, knowledge files, output structure. We build the smallest thing that could solve the job.
03
Evals on your real cases
We test against your actual inputs, not invented ones. You see where it wins and where it still gets fooled.
04
Ship where you use it
Custom GPT in ChatGPT, an embed in your tool, an API, or a small UI. Wherever your team will actually open it.
05
Handover and tune
Documentation, prompts, evals. Two weeks of changes after launch as it meets real users.
This is for you if
- YesYou have a repeatable knowledge-work task you keep duct-taping.
- YesYou want something live and useful in weeks, not a proof of concept.
- YesYou want to own the prompts and evals, not rent a black box.
Skip it if
- NoYou want a chatbot that just chats without a job to do.
- NoYou need a full data platform, not a focused GPT.
- NoYou will not put a single person on your side in the room with us.
Straight answers
Use no-code if the job is simple and you have the time to iterate. We get hired when the job has nuance that a generic agent gets wrong, or when the cost of being wrong is high enough that evals matter. We hand over the prompts and evals, so you are not locked in.
Most builds ship in two to four weeks from kickoff. The cap is your team's availability for review, not ours.
Your data stays in your accounts. If your team uses ChatGPT Enterprise, Claude, or Azure OpenAI, we build inside that. If you need on-prem or a specific model, we will tell you upfront whether the price changes.
Yes. Single-GPT starts at $3,500. Multi-GPT systems, retrieval-augmented setups, and integrations are quoted on the call.
Evals make this visible early. If the scores will not clear your bar, you find out in week two, not at the end. We would rather stop and tell you straight than ship a bad one.
