About

Matthew Juszczyk

Fractional Head of Product & AI Builder. Founder, StreamGist.

Matthew Juszczyk

I work best owning a product end to end: deciding what to build, building it, and running it after launch. I make the hard trade-offs and keep engineering, design, data, and operations moving together.

That approach comes from 15+ years in product, delivery, and operations at medical device, insurance, edge AI, and enterprise companies, where reliability mattered as much as the technology.

Since 2025 I have run StreamGist alone, from gaming analytics to land screening with LandGist. Agents watch production and draft fixes, a second model reviews every change, and I give final approval.

Operating range

Product leadership across complex and regulated environments.

Different industries, same job: decide what matters, ship it, measure it.

How I lead

Clear authority comes first.

People and AI should each know what they can decide, what they must escalate, and how success is measured.

Engagements

How I work with teams

Available for fractional product leadership and advisory, and open to select full-time roles. Most engagements start with a short call.

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

Building an AI product that has to work in the real world?

If any of this fits your team, write a few sentences. I read every note personally and follow up directly.
