Use it to accelerate LangGraph checkpoints and state.
When a pilot is late, unreliable or quietly losing its sponsors, we diagnose the actual cause from evidence and stabilise it with measured, reversible changes — or tell you plainly that it should stop.
Usually owned by: The engineering lead or sponsor accountable for a struggling AI initiative.
Troubled AI projects tend to look alike from the outside: a pilot that was “nearly ready” for two quarters, accuracy that seems to get worse as more users arrive, a growing list of special cases handled in prompts, and a team that has started to distrust its own measurements.
The causes are usually less mysterious than they appear. Common ones are an evaluation set that no longer represents real traffic, retrieval returning plausible but wrong context, retries that duplicate side effects, state that is lost between steps, or a cost and latency profile that forced compromises nobody wrote down.
A rescue begins by restoring a trustworthy picture of what is happening. Only then do we change things — in small, reversible steps, each one measured against the baseline, so the team and its sponsors can see confidence returning for evidence-based reasons.
Rebuild or repair the evaluation set from real traffic and known failures, so changes can be judged against something everyone trusts.
Separate retrieval, reasoning, tool, state, data and integration failures, and count them. Most rescues are dominated by two or three categories.
Address the largest failure categories first with targeted, reversible changes, measuring each against the baseline before moving on.
Present the measured trajectory to sponsors with a clear recommendation: continue with a defined scope, change approach or stop.
Immature projects improve when you fix things; failing ones do not, because the fixes are not aimed at the real causes. If changes are not moving a trusted measure, the measurement or the diagnosis is the problem.
Often not. A rescue can run alongside a limited pilot, using its traffic as evidence. Pausing is sensible when the system is causing harm or cost that outweighs what is being learned.
Rarely as a first step. Most rescue findings sit in retrieval, state, tools and evaluation. Replacing the model changes many variables at once and makes the picture harder to read.
Rescues usually start with a fixed-fee readiness review focused on diagnosis, then move to a fixed-scope sprint against the largest failure categories. Indicative ranges are published on the engagement pages.
Client results and public engineering are kept apart; the evidence method explains why.
No client case study is published for this situation yet. See all case studies.
Neul-owned work you can inspect — not client case studies or warranties, and never a requirement.

A scoping call can usually happen within days. The review itself starts once access is arranged; the access route is often the slowest step, so it is worth raising early.
Yes. Rescues go best with the original builders involved. Their context saves time and the improvements need to be theirs to maintain.
Then you receive the evidence for that recommendation and a summary of what was learned. Stopping a project on evidence is a better outcome than continuing one on hope.
Other situations we help with: launch production ai · automate a business workflow · make ai useful for a team · get an ai system approved.
Left alone, a struggling AI project consumes engineering time, erodes internal trust in AI generally and often ends with a decision made on politics rather than evidence.
