Product builder
I'm Head of Product at an early-stage AI company. Before that, 10 years at Balsamiq, an AI-powered wireframing and prototyping tool built for product teams: joined in 2016 as CRM Product Manager and Sales Support Lead for Olio, their internal licensing and entitlements platform, then took on PM of the core product in late 2023. The path shows up in how I work: close to customers, close to the product, and close to the code.
I do my best work where the person making the product judgment is close enough to the implementation to be accountable for it.
Now
Head of Product at an early-stage AI company in legal technology, working across two live products with a small distributed team. Right now that means defining the ICP, running product discovery, and deciding what is actually worth building next.
Featured case studies
Some of what I've owned end to end: shipping code, moving a room with data, and building the process the company ships inside. Click through for the full write-up.
Per-project to per-user pricing migration
Designed and shipped the Stripe-integrated billing page end-to-end, in production code, with Claude Code as build partner.
AI monetization for Balsamiq Cloud
Designed the per-tier allocations, overage packs, and competitive positioning for Balsamiq AI. Made the pre-launch case to halve what we'd pitched. "Electricity, not a parking meter."
