Ask Why It Won't Work and Other Lessons This Founder Relies on While Building from 0 to 1
TL;DR: Rick Song co-founded Persona in 2018 after five years at Square where he worked on fraud prevention and identity verification. He saw that one-size-fits-all identity solutions were falling short and built Persona as a customizable platform using low- and no-code building blocks. Song's distinctive approach centers on pre-mortems: asking 'why would this NOT work?' at every decision point. For hiring, he biases toward no when on the fence, spends 40 minutes of interviews understanding motivations rather than technical skills, and looks for 'glue' people from big companies who plug gaps. He approaches startup hiring as a segmentation exercise, differentiating Persona's humble, day-to-day focused culture from the typical 'rocketship' pitch. On product strategy, Song studies other companies' unusual strategic moves rather than starting from first principles, questioning whether those strategies fit his context. He has engineers sell and sit with customers to build empathy. Persona raised a $50M Series B, grew revenue 10x, and counted Square, Postmates, and Gusto as customers.
Key Insights
- Pre-mortem thinking (asking why something won't work) provides more useful information than confirmation bias about why it will
- Bias toward 'no' in early hiring - a wrong hire at 10 people is a 10% impact on team composition
- Look for 'glue' people from big companies who fill gaps and work across functions rather than hiring only startup veterans
- Study other companies' unusual strategic moves rather than going to first principles - then question whether they fit your context
- Have engineers sell to build customer empathy that improves product decisions
Actionable Takeaways
- Before extending an offer, write down all the ways this person might NOT work out and discuss with your manager
- Spend 40 minutes of a 1-hour interview understanding candidate motivations rather than testing skills
- Differentiate your hiring pitch from the typical startup 'rocketship' narrative - find what's uniquely attractive about your company
- Study comparable companies' strategies to find unusual moves worth experimenting with, then question why they might not fit
- Put engineers on customer calls to build product empathy and improve what gets built
