Open Questions — Seed Round

Unresolved questions surfaced by the seed-round research. Each is a research target for later rounds.

  1. Evidence quality of the US delay statistics. The headline figures (90-day payment cycle, $280bn annual cost, 70% facing delays) come largely from payment-technology vendors (Rabbet, Built, Billd, PYMNTS). Are these corroborated by independent regulator, census, or peer-reviewed academic data? Does the magnitude survive scrutiny?

  2. Retention beyond the UK. Is retention withholding documented as a problem outside the UK with comparable evidence? How do trust/escrow models (New Zealand’s escrowed retentions) compare in outcome to the UK’s proposed outright ban?

  3. Do prompt payment laws actually work? Where prompt payment legislation exists (UK since 1996, Australia, Canada, US states), is there hard evidence payment behaviour improved — or did delay persist despite the law? The UK 2026 reform implies the 1996 Act under-delivered.

  4. Under-researched markets. The seed round has strong US/UK/Canada coverage but little on the EU, Australia, South Africa, India, Southeast Asia, and African markets. What quantified evidence exists for each?

  5. Public vs private sector. Government and public clients are repeatedly named as slow payers (e.g. Ghana). How does the payment problem split between public-sector and private-sector projects?

  6. Both sides of non-payment. Sources so far are subcontractor-sympathetic. What are the legitimate contractor/client reasons for withholding — defective work, variations, valuation disputes — and how often is withholding justified rather than abusive?
