PM who codes
I go by Liz. I'm a PM at Balsamiq, an AI-powered wireframing and prototyping tool built for product teams. 10 years in product management: joined in 2016 as Sales Support Lead and CRM Product Manager for Olio, our internal licensing and entitlements platform, then took on PM of our 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.
This year I owned the design, front-end implementation, and QA for our per-project to per-user pricing migration, including the Stripe-integrated billing page, shipped with Claude Code as my build partner. I also led the AI credit pack monetization research and set per-editor AI credit limits so they behave like electricity: invisible in normal use, only visible when spiking.
I work best at the crossover of product judgment and implementation. I'm looking for that kind of room: small-to-mid B2B SaaS, AI-forward, teams where PMs can ship.
Currently: shipping our legacy-customer cancellation flow with Claude Code.

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."
Introducing Shape Up at Balsamiq
Introduced and adapted Shape Up for our size and existing cadence. Wrote the operating model, pitch template, and ongoing shaping work.
If you're building AI-forward product where PMs ship, run their own research, and own decisions end to end, I'd love to talk. I'm looking for small-to-mid B2B SaaS teams where product judgment and implementation live in the same person.

Kill the HiPPO — Chapter 3
How our owner and I decide what to build at Balsamiq: choosing a "season" of work (features, chores, or bugs), running a weekly Product Review Board, and shaping the roadmap through a monthly meeting. Interviewed by Steve McLeod and Siew Ann Tan, 2026.
