Episode notes
Poolside Onboarding Sparked The Acquisition
- Rahul met Grammarly CEO Shashir during a Superhuman onboarding and demoed the product by a pool, leading to later acquisition.
- Shashir demoed Coda there too, a meeting that seeded the shared vision for an AI-native productivity suite.
Use Outcome Metrics That Reflect Actual Work Done
- Measure productivity with outcome metrics tied to work done, not vanity stats. For email, track emails sent and percent written with AI.
- Superhuman users now send and respond to 72% more emails per hour and saved ~3.3 hours/week in enterprise case studies.
Survey Users After They Experience Core Value
- Run a 4-question survey after users experience core value: disappointment, who benefits, main benefit, improvement suggestions.
- Wait until users have used the product (e.g., Superhuman waits ~2 weeks and minimum sent emails) before surveying.
