- [Introducing Nous: The Chess Engine That Doesn't Search](https://pebblebed.com/blog/introducing-nous.md): Every strong chess engine wins by search. Nous does not: it imagines a whole line of play at once, judges it, and rewrites any part, the way a person does. Building it that way also made it an instrument, because a system that imagines, judges, and revises let us measure something the rest of AI is betting on but cannot usually see, whether a system can trust its own judgment. Here is what it showed.
- [Build: Automating the Built World](https://pebblebed.com/blog/build.md): From a seed conversation about shipping hundreds of thousands of buildings to compressing weeks of technical due diligence into hours—why we backed Build to construct the digital substrate for the built world.
- [On Computers](https://pebblebed.com/blog/computing-is-bigger.md): A walk through the computer-brain industry (CPU, memory, accelerators) from a $15B footnote to a $350B heavy industry in 2025. Its recent, and we speculate, near-future doublings change where value accrues for infra founders and application builders alike.
- [Ulysses: The Ocean Company](https://pebblebed.com/blog/ulysses.md): From a leaky seagrass-planting prototype in Dublin to the autonomous platform for the entire ocean—how Ulysses is building the Ocean Company.

Computational complexity gives us a real notion of hardness — and a sturdier foundation for thinking about what AI can and cannot do.
- [Agentist Manifesto](https://pebblebed.com/blog/agentist-manifesto.md): Work outside our respective zones of genius should go to agents wherever possible — and where it cannot, we should build toward making it delegable.
- [Escape Sequence](https://pebblebed.com/blog/escape-sequence.md): The same bytes can be a harmless string to an RFC 8259 parser and a cognitive exploit to a language model—until the boundary between data and instruction collapses in the systems we trust.
- [The End of Per-seat SaaS](https://pebblebed.com/blog/per-seat-saas.md): Per-seat SaaS assumed humans bound load, attention, and cost. Autonomous agents break those bounds—and force pricing and product to anchor on work, outcomes, or coordinati
