Saible, a Birmingham-based construction FinTech building software to stop project money from being delayed, withheld or trapped before it reaches suppliers, has raised £2.9m from angel investors.

The funding comprises £2.1m already raised and a further £800,000 angel round, taking Saible’s total funding to £2.9m.

Saible is working with the Environment Agency and BAM Nuttall on public-sector pilots designed to test its payment-control model on live, government-backed construction projects. The first pilot is expected to be a £1.5m–£2m footbridge replacement, due to commence in summer 2026, with a programme duration of 12–16 months.

The pilot followed work by a Cabinet Office-sponsored group examining payment problems in construction and is intended to generate early evidence on payment visibility, supplier payment timing and supply-chain reach that can inform wider public-sector payment reform.

Alongside the angel round, Saible is opening a limited £50,000 Crowdcube-hosted allocation from 15th July to 14th August, intended to allow smaller construction businesses and industry participants to invest alongside Saible’s angel backers.
