Mark Barbir — CEO

Product & technology leader building daily-use AI for product teams. I’ve spent 20+ years turning ambiguous problems into shipped products and scalable orgs, most recently as Co-founder & CEO of Earmark, the AI Chief of Staff for product teams. We’re a bot-less, privacy-first, live AI that turns meetings into finished work before they end. Previously: CTO at ProductPlan with a $50M exit in 2023. Before that: Mindbody, scaling engineering from 100 → 250, $50M → $100M, and integrating six acquisitions. I care about velocity, clarity, and trust - shipping that compounds, security that earns enterprise approval, and carefully crafted products people love. If you’re exploring AI-native product workflows, enterprise adoption, or PM/ProdOps excellence, I’m always up for a real conversation. Specializations → AI Product Strategy (applied LLMs, privacy-first, multi-agent) → Product Strategy & Management (0→1, 1→N) → Technical Leadership & Org Design → Team Building & Global Scaling → SaaS Platform Architecture & Reliability → Product Design & User Research → PLG + Enterprise GTM & Pricing → Security, Privacy & Compliance (SOC 2, vendor risk) → M&A Technical & Org Integration → Operating Cadence, Metrics, and PM Ops

Stackforce AI infers this person is a SaaS and HealthTech product leader with extensive experience in AI-driven solutions.
