The craft

Different companies, one problem. The core of most products is data, and it's personal, whether it belongs to a person, a company, or a brand. People hand it over in trust. My craft is building the surfaces where people and data meet, and the systems underneath them.

The arc

  • Customer.io. The right data to the right person at the right moment: the MCP proof-of-concept, an agent chat interface, and mobile SDKs as a surface for collecting and delivering data.Core: customer data → human connection · Surfaces: messaging, chat, agents, API, mobile

  • Moov. Opened up payment infrastructure through a developer platform.Core: payment infrastructure · Surface: API, SDK · Developers

  • Slyce. Mapped a retailer's full catalog so a shopper could snap a photo and find the item, including the scanning hardware that lived on the floor at stores like Home Depot.Core: the catalog · Surface: visual search, scanning hardware · Consumer

  • Ipreo. Made a vast store of corporate knowledge reachable by an executive offline, on an iPad, in the back of an Uber, minutes before trying to land a deal.Core: corporate & market intelligence · Surface: offline mobile · Enterprise

  • Blippar. Building toward a knowledge graph of the physical world.Core: the physical world as data · Surface: the camera, AR

  • Lumi. Built the live feedback loop for events: physical voting keypads in the room, tallied and shown back to the audience as it happened, firmware and all.Core: collective insight · Surface: event keypads, firmware

  • Personal builds. Cleo, an AI meal-planning assistant for families, built across UI, chat, and API.On my own time

Enterprise knowledge → a conference room → the physical world → a retail catalog → payment infrastructure for developers → people and the moments to reach them. The same problem, deeper each time.

Customer.io

I made the case for a multi-channel, mobile-inclusive strategy. I'd noticed that customers who engaged their audiences across more channels drove more value, and our pricing followed the value delivered. Serving that pattern well was good for customers, and not coincidentally for us.

Writing

I write at Head for Product about building products and how I think about the work: product management without the dogma, and what I learn shipping things as a builder. A new essay every few weeks.
