The Flech logo, in three pieces The complete Flech logo.

Flech stops the drift.

The complete Flech logo.

Every team knows this one. A feature ships. The team made a trade-off during design, engineering built the revised version, and the decision never made it back to the spec. Everyone involved knew why. Nothing was broken.

Three months later, someone new picks up the next change. The spec says one thing, the product does another: it has drifted from the decision, and nobody noticed.

“Why did we build it this way?”

The designer has moved teams. The engineer has left. The new team has the code and the designs, but not the reasoning behind them. An old debate starts again. A deliberate trade-off looks like a mistake. They make the best call they can, without knowing what they might be undoing.

The work carries on, but the understanding starts over.

As code gets cheaper, speed is no longer the scarce thing. Precision is. The teams that win will not be the ones shipping the most. They will be the ones drifting the least.

AI agents now write more of the code, but they do not carry the reasoning. Given a spec that no longer matches the product, they build confidently on top of the drift, and the gap widens.

Flech is a living roadmap that keeps decisions and their reasoning connected to what gets built. As intent changes, that history stays with the work. The next person can see what was agreed, why it changed, and whether the product still reflects it. They build on what the team learned, rather than piece it back together.

Flech syncs reality to intent. When they drift apart, you are the first to know.

Software doesn’t fail in the code. It fails by drifting.

Three forms of drift.

01 / 03
That’s not what we agreed.

Translation Drift

Everyone left the room with a different version of the same decision. The code shipped one of them.

02 / 03
Nobody remembers why.

Decision Drift

The decision lives on in the code. The reason left with whoever made it. Now nobody can defend it, or safely change it.

03 / 03
On time. On spec. Off target.

Expectation Drift

Every ticket closed, every test green. The spec stopped matching what people needed months ago, and the team (and now its AI agents) built confidently on top of the gap.

In practice

Intent that stays attachedto the build.

Two sides of the same problem: what you meant,

and whether you can still prove it after ship.

AlignmentIntent stays wired to what ships.

  • Lock the decision that started the work before code fans out.
  • Keep the live link between PRD judgment and the release that follows.
  • Catch drift while the team can still change course — not in a post-mortem.

ControlDecisions stay owned and checkable.

  • Named owners on intent — not a pile of tickets with no account.
  • Audit the path from “we decided” to “we shipped” without archaeology.
  • Your cloud, your record of why — not a black box that leaves with the vendor.
FAQ

Frequentlyasked questions

How Flech works, what joining means, and what we will not claim early.

Flech keeps product intent aligned with what is actually built as teams scale. The job is zero-drift between the decision that started the work and what ships — so the judgment does not die in a frozen doc.

Those hold artefacts: docs, tickets, status. Flech is aimed at the live link between intent and build — whether what you meant is still true of what left the door. It is not another place to write specs that go stale.

No. It is for teams who already decide and ship. The point is to keep those decisions checkable against the build, not to automate the people out of the loop.

You are on the early list. We write when there is something real to show or a seat to fill. No countdown clock. No spam. No fake launch date.

Waitlist signup is your email for Flech updates only. Product data handling, residency, and access controls will be spelled out before any paid or production use — we will not invent a privacy story here.

When there is a real build path and a seat worth taking. We will say so then. We will not publish a quarter we cannot defend.
