The Signal Layer: What to Build When Anything Can Be Built — Lena Hall, Akamai

Summary

AI has made implementation nearly free—autonomous agents went from solving a fraction of coding tasks to 80%+ success—but this commoditization means your competitive advantage now lies entirely in *what* you choose to build, not *how* you build it. The real job is deciding where to point the machine, not running it.

Key Takeaways

  1. Autonomous coding agents tripled from solving a fraction of tasks to high 80s on benchmarks, yet shipping barely moved a third. The gap reveals that implementation is converging for everyone simultaneously, making differentiation impossible through code alone.
  2. The 'Signal Layer' framework: split product strategy into two halves—(1) Build side: knowing your signal clearly and why it's yours, not average; (2) Ship side: emitting that signal without distortion through content and go-to-market. Most founders optimize only one.
  3. Find what to build by feeling the need yourself, not surveys. Build something you and your friends need before the market forms—your own signal is the only non-crap signal available when data can't yet see the opportunity.
  4. Anything measurable gets automated by AI models. Compilers and test suites are free graders that let models train until they win. Anything visible is immediately replicatable, so visibility itself becomes a liability without authentic differentiation.
  5. AI is a 'convergence machine'—when everyone asks the same question, it gives identical answers from historical data. To break convergence, you need a contrarian point of view on where the market is going, then use automation to execute it faster than competitors.

Transcript Excerpt

[music] >> How is the conference for all of you so far? Great. Awesome. Um well, I think this was the best most productive year for so many of us. I'm Lena. A few days ago, I solved a production incident on a trail near a waterfall. My friend ran 18 agents while riding his bike. We're literally drowning in abundance. We have more output, more speed, more leverage than any of us have ever had. So, why do we have this feeling like the ground underneath is moving too fast? One of the engineers that I met at this conference said yesterday that it feels like the opportunity cost for not working 9:00 a.m. to 9:00 p.m. 6 days a week is too high right now. So, we're all token maxing. We're all working all the time. But the same abundance that made you fast, it also made everyone else fast. So, now…
