Built from the inside out

Before AWS embedded engineers with customers, it ran the experiment on itself.

A year before last month’s Forward Deployed Engineering launch, AWS Professional Services stood up a small pathfinder team — APEX — with one mandate: redesign how ProServe itself delivers, using AI agents end to end.

The result is now public. A multi-agent Delivery Agent that spans requirements, architecture validation, implementation, security review, testing, and deployment — working alongside human consultants on live engagements globally. Engagement timelines compressed from months to days. LexisNexis reported 60% faster code delivery working this way.

Francessca Vasquez called the approach “built from the inside out,” and credited Rachael Wang and the APEX team for proving it. That framing matters more than the tech.

Here’s the principle I keep coming back to from years of working with founders: never sell a transformation you haven’t lived. Customers can tell within one meeting whether you’re describing something you did or something you read.

The reason forward deployed engineers can walk into an enterprise and compress timelines isn’t magic tooling. It’s that the delivery method was pressure-tested on the messiest customer available: yourself, first.

Dogfooding isn’t a slogan. It’s the credibility layer under everything else.
