Life at Promise & Proof
Life at Promise & Proof
You work inside the business, not beside it.
Our engineers sit inside client teams, next to the people who own the problem. You see the data, the workflow, and the P&L line your work is meant to move.
The people who scope it build it.
No hand-off between a strategy team and a delivery team. You help shape the brief, you build the system, and you stay through rollout.
Whichever model fits the job.
We build with Anthropic, OpenAI, Google, Meta Llama, Mistral, and open-weight models, and set the orchestration, evaluation, and vector store choices on every build.
Measured in outcomes, not hours.
Success criteria are set before the first line of code: revenue, margin, hours reclaimed, adoption. Every win becomes a reusable playbook, so your work compounds.
What we value
Three things we hold each other to.
Make big promises.
We take on the work that matters most to the business, and we say plainly what it will change.
Keep them.
We set the success criteria before we write code, and we stay until the system is used.
Operators first, engineers always.
We think like the people who run the business, and build like engineers who have to support what they ship.
