Y Combinator. A concrete senior-engineering walkthrough rather than a panel: Holtz compares Claude Code and Codex, orchestrates several coding agents in parallel, and marks "slop-free zones" where generated code is not allowed to land unreviewed. The setup embodies the article's rules — repository context, small reviewable patches, and the human staying architect while the agents do the typing.
Holtz builds Conductor, one of the tools shown, so treat the tool choices as one practitioner's stack rather than a ranking. The durable part is the discipline: parallel agents, human architecture ownership and zones where slop cannot land.
Set up a multi-agent coding workflow with explicit review boundaries so generated changes stay small, tested and owned.

HubSpot AcademyBrenna Zenaty, Adriti Gulati
Closes our biggest vertical blind spot: nothing in the catalog spoke directly to support and customer-success teams. HubSpot Academy is free, well-produced, and refreshingly concrete — it walks through AI-assisted ticket triage and a knowledge-base agent rather than staying abstract, and the certificate is free too, not a paywall bait-and-switch.
