Spec-Driven Development for Startups

In spec-driven development the specification, plus the tests or scenarios that define success, is what humans write. Agents write the implementation and keep iterating until the spec is satisfied. A YC partner calls the result an AI software factory, and StrongDM has published how its AI team runs one under two rules: code must not be written by humans, and code must not be reviewed by humans. Here is what that actually takes, what it changes about your team, and where it still breaks.

Forward Deployed Engineer: A Founder's Guide

A forward deployed engineer sits inside your customer's operation and makes your product actually work there: mapping the real workflow, wiring into their systems, and tuning until the numbers move. Palantir made the role famous, and in 2026 nearly every serious enterprise AI company is hiring for it. The founder of a Y Combinator company running AI support agents for DoorDash calls this role the biggest bottleneck in every enterprise AI deployment. Here is what the job actually is, what it costs you per logo, when you need one, and which parts an agent can now absorb.

AI for Field Service: The Founder Playbook

Field service is a phone business. Someone's air conditioning dies, they call three companies, and the first one that picks up and books the visit wins the job. The company that lets the call ring out just lost thousands of dollars. That simple economics is why AI voice agents have become one of the sharpest wedges in vertical AI, and why Avoca, a Y Combinator company building what it calls the AI workforce for the physical economy, is now valued at a billion dollars. Here is what AI for field service actually does, why the phone is the whole game, and the founder playbook you can copy whether you sell to these businesses or run one.

AI ERP: A Startup Founder's Guide

For most of software history the general ledger, the system that records every dollar a company moves, barely changed. The rest of the finance stack modernized around it while the core stayed slow, rigid, and consultant-heavy. AI ERP is the attempt to rebuild that core around a language model, so the software reads documents, drafts entries, and closes the books instead of just storing numbers you key in by hand. Campfire, an AI-native ERP out of Y Combinator, is winning startups off NetSuite by betting the whole company on that idea. Here is what an AI ERP actually is, why the opening exists, and what founders in any category can copy from the playbook.

AI Developer Tools: The 3x Productivity Gap

For decades the software your team ran barely decided who won. The best CRM against the worst one did not 3x anyone's revenue. AI developer tools broke that rule. On Greylock's Change Agents series, Box CEO Aaron Levie argues that the coding tool a team uses is now worth a two to three times difference in what it ships, and that the gap compounds every week the frontier moves. This is a guide to why that is suddenly true, what the real categories of AI developer tools are, and how a founder should choose without betting the company on hype.

Self-Improving AI: A Founder's Guide

Self-improving AI sounds like a research fantasy: a model that rewrites itself into something smarter. There is a nearer version founders can build this quarter. Instead of a model that improves its own weights, you wire parts of your company as AI loops that watch what happens, act, check their own work, and adjust, so the business gets a little better every cycle without anyone filing a ticket. Y Combinator general partner Tom Blomfield laid out the blueprint in a talk on building a self-improving company. Here is how to turn it into something you can actually run.
