Why it matters

A model nobody uses is a model that did not happen.

I started in consulting, so I learned that early. Most of my career has been spent in the gap between "the notebook works" and "the business changed what it does."

  • 9 years
  • 4 companies
  • 5 industries
~29%Search precision

More relevant results for AI agents, inside a sub-millisecond budget. No added latency.

−90%Manual analysis

Weeks of reading customer reviews replaced by a ranked list of what to fix, with evidence attached.

40→23%Customer churn

Segmentation, a 7-day propensity model and timed retargeting, on a base of five million customers.

Lab · built in the open

I built Beane, a deep research harness that ranks #1 globally on DeepResearch Bench II.

And #2 on the original DeepResearch Bench. One question in, a cited report out: it reads a hundred sources and checks every quote against its page in code. Built from scratch, its research runs on small and mid-sized models.

How I work

Three rules I do not bend.

They exist because each one has cost me something to learn. They are also the fastest way to tell whether a project is real.

01

Agree upfront on what proves the idea wrong.

Written down before any modelling starts. It is the cheapest way to kill a bad project early.

02

Never ship without an evaluation.

If there is no way to tell whether the output is good, there is no way to tell whether it got worse.

03

Give stakeholders something they can poke at.

A simulator beats a slide. People trust a number they were allowed to argue with.

Background

Marketing science, then AI product, then infrastructure.

Founders and C-level stakeholders in every role. Solo on the AI work, sole technical lead in the marketing-science years.

Notable brands

The names on the other side of the work.

Some I worked with directly on pricing and marketing science. Others I reached through the AI products I built, where the brand count runs into the hundreds.
