Product Weaver

About us

We did this work by hand for years.

Product Weaver is made by Pancrazio Auteri and Giulio De Luise. One built a career on deciding what to build and taking it to market. The other on turning those decisions into systems that work. The plugin is our method, written down so your AI assistant can run it.

Product Weaver is a free, open-source plugin for Claude, ChatGPT and Codex, and GitHub Copilot that turns customer interview transcripts into a jobs-to-be-done knowledge base, with every quote checked word for word against its transcript.

Code got cheap. Knowing what to build did not.

AI assistants write software in minutes. So the costly mistake has moved: it is building the wrong thing, fast. We arrived at this from two sides.

  • “The new bottleneck isn't how to build. It's figuring out what to build.”
    Pancrazio, on LinkedIn
  • “Code is cheap. Judgment is not.”

Who we are

  • Pancrazio Auteri

    Founder · Berkeley, California

    Pancrazio started a first company in 1996 and co-founded TVBLOB in 2003, a connected TV platform that Minerva Networks acquired in 2011. Then came product leadership at TiVo, Fing and AudienceView, where Pancrazio was Chief Product Officer. Three exits as a founder. Since 2023 Pancrazio runs Product Expanse, helping startups reach product-market fit, traction and their next round, and advises founders at UC Berkeley SkyDeck.

    What goes into the plugin

    The method. How to read an interview for what the customer is trying to get done, and how to turn that into a decision.

  • Giulio De Luise

    Co-founder · London

    Giulio has spent 25 years turning decisions into working systems: enterprise software first, then products, platforms and data for fast-growing companies. Giulio has led engineering and data teams and founded companies. Today, through Weaver37, Giulio is a fractional CTO for teams building with AI agents.

    What goes into the plugin

    The discipline. Every quote checked word for word against its transcript, and no interview content that leaves your machine through the plugin.

What we distilled

The path from the first interviews to the first customers, one part at a time.

  1. 1In the plugin today

    Insights from interviews

    We read transcripts the slow way, one by one. The plugin reads yours and keeps only what customers really said.

  2. 2In the plugin today

    What to build

    A map of the jobs, the outcomes and what people use now, with the gaps to ask about next.

  3. 3Coming next

    Go-to-market and traction

    Positioning, the sales story and the first customers start from the same evidence. This is the part we are building now.
