CTO/COO @ KOHO | When Your Developers 10x, You Hire More — Not Fewer

Jonathan Klein is the CTO and COO at KOHO, a Canadian fintech company, which means shipping AI slop into production is simply not an option. He's also someone who grew an engineering org from 20 to 600 people at Wayfair, then deliberately chose to go smaller again to get back closer to the work. Jonathan has a take on token capping that he's happy to defend.

*What you'll learn:*
- Why KOHO moved to a full-stack model and how Figma Code Connect is changing what front-end development even means
- How AI is shrinking the atomic unit of a team from six devs to four — and where those people are going
- Why judgment and architectural taste are now the scarcest skills on any engineering team, now that code itself is cheap to produce
- The "swarm of code reviewers": specialized AI agents reviewing security, maintainability, and architecture separately before a human ever looks at the PR
- Why he requires candidates to use AI in interviews and designs problems hard enough that they have to
- The hype anxiety problem — why people feel like they need an agent running 24/7, and how to give your team permission to shut it down
- His contrarian take: if your developer goes from 1.5x ROI to 10x ROI, the answer is to hire more, not fewer
- The insight from The Power of Full Engagement he keeps coming back to: the fundamental currency of productivity is energy, not time
