Matthew Juszczyk · Fractional Head of Product & AI Builder

I don't just plan AI & data products. I build them.

Battle-tested in medical devices, insurance, and edge AI. Now I run a multi-product AI company alone: agents do the work, I approve every change.

Experience across

Track record

Results where mistakes were expensive.

Before StreamGist, I led product and delivery in regulated and complex companies.

30% faster to market

DePuy Synthes (Johnson & Johnson), via SEI

Launched two FDA-regulated arthroscopic devices and brought Agile delivery to medical device work.

20+ engineers coordinated

Blaize

Led core modules of a low-code edge AI platform and contributed to proposals behind a multimillion-dollar defense agreement.

5× users, US to global

Liberty Mutual

Took reinsurance software from paper to digital and from about 20 US users to 100+ global, releasing every two weeks.

50+ initiatives in one view

Black & Veatch, via Apex Systems

Set priorities for a retrieval-augmented AI assistant for engineering policy and gave leadership a single portfolio view.

Engagements

Two ways to work together.

Most teams start with the review. Then I build what it designs.

Two weeks, one AI workflow

Pilot-to-Production Review

For an AI pilot that works in a demo but isn't trusted in production.

  • Written operating design: who decides what
  • Failure-mode and fallback plan
  • Success metrics with a baseline
  • Go/no-go readout, then I build it

Start with a review

Two to three days a week, three-month minimum

Fractional AI & Data Product Lead

For a team that needs an AI product owned and built, not just planned.

  • Decide what to build and what to cut
  • Build it: prototypes, product, agent workflows
  • Run it: monitoring, fixes, and controls
  • Lead your engineers, or hand off to them

What I build

Need an AI product built, not just planned?

Write a few sentences about the product or pilot. I reply personally, often within hours.
