Built by people who know the industry.

No Slip started with a straightforward observation: UK contractors routinely lose delay claims not because their claims are wrong, but because they cannot prove what happened, week by week, with evidence that stands up.

The planning tools are mature. The contract frameworks are well understood. The gap is in the recording layer between them. Without a structured, contemporaneous record of programme variance, the claim narrative gets reconstructed after the fact. Retrospective records lose in adjudication.

We built No Slip to be that recording layer. Simple enough that planners actually use it every Friday. Rigorous enough that the record holds up when it matters.

Construction programme slippage is inevitable. Delay claims are not. The difference between a contractor who successfully defends a claim and one who does not is almost never the quality of their legal team. It is the quality of their contemporaneous record.

No Slip bets that a tool which makes weekly programme recording simple, consistent, and immutable is genuinely valuable to every contractor running capital programmes in the UK. The fornesic module is the proof case: a contemporaneous record is worth orders of magnitude more than any amount of retrospective reconstruction.
