Product Manager, Post-Purchase Sep 2024 — present · SeattleAI knowledge workplace, internal
- Shipped "WorkBrain," an AI workplace agent that unifies each person's docs, meetings, and chats into one self-maintaining knowledge base, so AI works from the same grounded context.
- Set the trust bar for launch with a 3-layer eval (offline, ablation, adversarial), gating rollout on zero hallucinations on the launch eval set; ablation showed the self-correction layer was worth +8.3 pp accuracy.
- Added a reflector loop that turns each user edit into a written lesson, so WorkBrain improves how it works over time — keeping a human quality bar on an autonomous system.
Marketplace trust, economics & integrity
- Defined and executed the global Free Return strategy — the platform's global Free Return cost line across 4 markets. Validated ROI through PSM analysis (US GMV +3.78%, UK +7.60% per exposed user, both exceeding Finance targets), securing long-term investment from leadership.
- Made the strategy sustainable with a 0→1 seller–platform cost-sharing model, shifting buyer-fault return costs from 100% platform-subsidized to tiered co-funding — platform spend −42% with zero negative seller impact.
- Drove 4 consecutive quarters of NPS growth to 29.1 by revamping eligibility criteria (coverage 80% → 89%) and expanding pre-purchase awareness from 43% toward 60%+ across discovery and conversion surfaces.
- Built a category-specific trust framework mapping each vertical's dominant barrier (authenticity, size/fit, quality) to modular solutions; first shipped luxury authentication — pre-purchase conversion +1.05%, per-user GMV +9.97%.
- Identified that high-value users (top 5% of users, 35% of GMV) repurchase on differentiated benefits; launched "Premium Protection" (faster refunds, unlimited returns, priority support) — AOV +1.0%, repurchase GMV +2%.
- Saved the platform a seven-figure annual sum by identifying abusive buyers and excluding them from free return, returnless refund, and speedy refund — keeping after-sale benefits for trusted users.
