Tarun Sachdeva - Traces Nov 02, 2026

Show notes

This week we're joined by Tarun Sachdeva, founder of Traces and previously head of product at Wattpad. Traces gives coding agent sessions a home: a CLI that collects sessions from Claude Code, Codex and other harnesses, and traces.com, where you can share them like pushing code to GitHub and link them to the commits and pull requests they produced. We talk about why agent sessions are decision data worth keeping, privacy and sharing defaults, rethinking code review as its own agent session, Surfaces for visualizing tokens, skills and security risks, and how teams can use trace data to learn without it feeling like surveillance.

Boris Tane - Polylane Oct 19, 2026

Show notes

This week we're joined by Boris Tane, founder of Polylane and previously founder of Baselime, the observability startup Cloudflare acquired in 2024, where he went on to lead Workers observability. Polylane builds a live topology map across your cloud, observability tools, and repos so an agent can detect, investigate, and fix production issues before anyone gets paged. We talk about why bolted-on AI tools fail for on-call, how Polylane's memory systems work, using trajectory analysis to vet pull requests before they merge, and what happens to the on-call rotation as agents write more of our code.

Bobby Grayson - Deciduous Sep 28, 2026

Show notes

This week we're joined by Bobby Grayson, a longtime Elixir developer and the creator of Deciduous, a decision graph that gives LLMs a living memory.Deciduous stores goals, options, and outcomes in a SQLite-backed graph that agents like Claude Code can query as they work, so they remember why decisions were made instead of repeating past mistakes.We talk about how it slots invisibly into an agent workflow, how teams share decision graphs, the surprising authors using it to organize their books, and where coding is headed in the next five years.

Scott Lanoue - CoMail Sep 14, 2026

Show notes

This week we're joined by Scott Lanoue, the creator of CoMail, a cooperative email service built on the AT Protocol.Getting a self-hosted mail server to actually land in the inbox is a months-long slog of warming IPs and building domain reputation, so CoMail pools that reputation across everyone sending through a shared relay.

We talk about how atproto identity lets CoMail vend out trust instead of spam scores, what it means to store your mail in your own PDS with spaces, and why a co-op might be a better shape than a startup for a protocol with no moats.

Jacob Miller - DiffUI Aug 17, 2026

Show notes

This week we're joined by Jacob Miller, founder of DiffUI, an AI-driven UI design tool. DiffUi uses diffusion models to generate UI designs, and then uses a large language model to convert the designs to code. Jacob is a design systems expert and has a lot of experience with design systems, and that's baked right into the product.
