Nobody Takes Notes Anymore. 5 Million People Let AI Do It Instead.

This week we sat down with Rob Williams, co-founder and CTO of Read AI, to dig into what 5 million monthly active users actually looks like at the product and infrastructure level. Most people know Read AI as a meeting note taker. Rob winces every time he hears that. What it really does is capture every conversation across your organization and turn it into intelligence — daily briefings, smart routing, and organizational context that moves itself to where it needs to be.We also covered AI companion apps and the unit economics behind them, the AI adoption divide inside enterprise companies, and Opus 5.5 dropping this week.

We cover:

• What Read AI actually is beyond the meeting note taker label
• The daily briefing feature — hot and hydrated context before every meeting
• How smart routing sends meeting data automatically to the right team
• Why some companies set data retention to 7 days and why that makes sense
• Navigating the AI adoption divide inside enterprise organizations
• Rob's vision for information moving itself in three years
• Why meetings are the biggest investment most companies make and nobody measures
• Hot Girl Hotline — an AI relationship advice app and why the unit economics work
• AI as a sounding board vs a solver and why both have value
• Opus 5.5 dropping and what cheaper intelligence means for builders
• Token economics of running 5 million monthly active users

If you are building with AI, managing a team, or want to understand where enterprise AI is actually heading, this episode is for you.
