How Michael Chime built and sold Prepared, an AI for 911 dispatch

Executive overview

America's 911 centers run on technology designed for landlines, and call takers manually transcribe every detail while someone's life hangs on their notes. Michael Chime co-founded Prepared at Yale, dropped out, and built AI tools that sit alongside existing dispatch systems rather than replacing them.

The company grew from a free product used by a handful of schools to a paid platform processing 30 million calls per day, covering 100 million people across 49 states — acquired for $640M.

Giving the product away for free to the first thousand cities was the distribution hack that unlocked a procurement-locked market.

Origin and early pivot

• A school shooting near Chime's hometown when he was 12 shaped his focus on emergency safety
• At Yale, he met co-founders Dylan and Neil — both grew up near Sandy Hook
• Their first product was a school safety app; 911 integration emerged when schools wanted to share images with dispatchers during drills
• Visiting a 911 center for the first time revealed operators manually typing stream-of-consciousness notes that first responders would act on

Distribution strategy: the bottoms-up unlock

• Investors warned against government: hard to sell, small market — Chime treated this as a signal to focus, not retreat
• Procurement in government blocks startups the way corporate IT once blocked SaaS
• The playbook: give the product free to end users, prove a better experience exists, then convert on technology merit — not procurement politics
• First ~1,000 cities paid nothing; they became advocates who made the commercial expansion possible

Product evolution from usage data

• Launch week: a CPR call saved using live-stream coaching — validated the core product immediately
• Month 1: 350 incidents; Month 4: 60,000 monthly messages — rapid adoption exposed new problems
• Language translation emerged from watching centers copy-paste texts into Google Translate; Prepared built it in natively
• Translation expanded from text to real-time audio transcription on live calls
• AI voice agents now handle non-emergency calls (noise complaints, parking tickets), freeing human agents for emergencies

Building in a safety-critical environment

• Ripping out existing 911 systems creates catastrophic risk if a single call is missed
• Prepared's architecture integrates alongside current systems rather than replacing them — no vendor had done this before
• Every new product feature originated from sitting next to a dispatcher and watching them hit a problem

Founder role evolution

• Early stage: Chime was selling directly and visiting centers daily
• Scaling forced a transition from doing to managing people who do — a different and uncomfortable skill set
• The failure mode: founders keep doing their last job when the company needs them in their next one
• Customer obsession is the non-negotiable constant; everything else adapts as headcount grows

On mission as a talent strategy

• Ambitious missions attract better talent willing to work harder
• "If we build things and someone else mass-distributes them and saves millions of lives — that's great too"
• The urgency is less about personal legacy and more about the cost of inaction: lives lost daily to status-quo decay
