What is FDE as a service?
FDE as a service definition
FDE as a service means buying forward-deployed engineering from a firm, for a defined engagement, instead of hiring a forward-deployed engineer onto your payroll. The engineer still works inside your team, in your systems, and still owns delivery end to end. What changes is the contract: a scoped engagement with a start, a set of deliverables and a way to stop, rather than a hire that takes months to make and longer to undo.
The engagement follows four moves. Diagnose: two weeks mapping the workflows and systems where the hours go, measured on real data, ending in a prioritized opportunity map and one costed build proposal. Prototype: a working proof on your own data, so the business case rests on evidence. Build: production-grade software, tested and wired into the tools your team already uses. Operate: a monthly retainer that monitors and evaluates what was built, keeps its models and integrations current, and ships the next item on the queue.
Who it suits
Teams that have a real problem and nobody free to own it: an operator whose work is stuck between systems, a founder with an AI prototype that has to become a product, a company whose last build stalled. It suits a team that wants the work done in its own stack and handed back maintainable, and that would rather see a result in weeks than open a requisition.
When it is the wrong choice
When the work will never end and is central to the product, hire. A forward-deployed engineer from a firm should be working towards your team owning the system, and if there is no team to hand it to, the engagement has no end state. It is also the wrong choice when the problem is undecided strategy rather than undone engineering: a Diagnose sprint can settle a scope, but it cannot settle a company's direction.
