What sits behind the guarantee

01
A proven AI system, set up in hours.
We set up a proven AI system on your company data. An engineer stays on your team to run it, and the guarantee covers that engineer.
02
90 days to judge the fit.
You see the fit on the job. If it is wrong, we replace the engineer at no extra cost.
03
No project scope to get stuck in.
We do not scope projects. We work as your ongoing AI partner, and you can cancel anytime.

What the guarantee covers

It covers the engineer we place on your team. If that engineer is not the right fit in the first 90 days, we replace them at no extra cost. The engineer runs a proven AI system on your company data, and we run performance check-ins through the whole window, so a fit problem shows up early.

How a swap works

You tell us the fit is wrong, and we replace the engineer.

WHAT TRIGGERS A SWAP
The fit is wrong.
You get 90 days to confirm the engineer fits your team and your work.
WHAT IT COSTS
No extra cost.
We replace the engineer at no extra cost. The plan stays from $3K a month, cancel anytime.
WHEN THE 90 DAYS RUN
From the start date.
The window runs from the engineer's start date, with performance check-ins through all 90 days.

Five questions to ask any provider about a guarantee

  1. What counts as a reason to swap: skills, fit, or both?
  2. How long does a swap take, and is it in writing?
  3. Does a swap cost anything?
  4. When do the 90 days start?
  5. What happens on day 91?

Bring these to the consultation call. We answer the first, third and fourth above. Ask every other provider the same five.
