Experimentation Platform


Catapult, Etsy's internal platform for running and evaluating product experiments, was used constantly but had never had dedicated design investment, and for part of the year it had no PM. I stepped in to set the product vision and hold the team's operating structure together.

Our insight was clear: experiment health drives better product decisions through set up, evaluation, and history. Better documentation produces better learnings, better learnings build a trustworthy record, and that record shapes where we invest next.

 

Role

  • Staff Product Designer, functioning as squad Product Manager

  • Research lead across users, initiative leads, and executive leadership

  • Systems design — site map, service design blueprint

  • Team operations — sprint cadence, check-ins, work tracking

Impact

  • 90% conclusion completion, up from 50%

  • +15% hypothesis quality score

  • 5 improvements shipped to the experiment details page in one quarter

  • 3 levels of the org researched, from daily users to executives

 

Tooling

Utilized Claude to turn raw research notes into testable hypotheses tied to company outcomes, and to define measurable benchmarks like engagement.

Leveraged a Figma-based design system in combination with Cursor to rapid-prototype the platform vision and feature concepts.

 

Challenges & Solutions

Experiment Hygiene

Experiments launched with vague hypotheses and inconsistent metrics, so their intent was unclear. We added AI grading of hypotheses and conclusions against criteria the product team defined, a nudge toward better-formed experiments.

Evaluation

Key data was buried in hover states, and the metrics table couldn't be filtered, sorted, or searched. I rebuilt it in plain language with filter, sort, and search, and reordered the page around what users need first.

 

Historical Context

Poor metadata made past learnings slow to find, with no confidence the search was complete. We linked related experiments into a parent-child chain and added AI summaries of product docs, so teams can see the story behind the current test.

leading through ambiguity

Work went untracked, and decisions leaned on assumptions instead of evidence. I introduced a regular cadence and work tracking with the squad and leadership. Turned research across three levels of the org into the Q3 roadmap that aligned stakeholders.

 

What shipped

Following the Q3 roadmap, the team shipped a redesigned experiment details page — filterable metrics, parent-child experiment linking, an AI-generated summary of product documents, an AI-generated score for the hypothesis and conclusion, and a reworked page hierarchy to surface what actually mattered most.
