Halfsy secures £483k to prevent high-value checkout failures

High-value sales often fail due to rigid bank limits, a challenge London-based Halfsy Ltd addresses through a payment orchestration platform. The company, which operates in the field of information technology service activities, has secured £483k in new funding, resulting in an estimated post-money valuation of £1.2m.

Incorporated in February, the startup targets premium merchants whose customers might spend weeks researching purchases like £2,500 sofas or bespoke jewellery only to face rejection at the final click. The technology intercepts false declines in real time, which are estimated to cause five times more revenue loss in the UK than actual fraud.

To mitigate these issues, the software offers a frictionless multi-card split option that keeps buyers within the checkout flow. This system performs simultaneous authorisation across all cards to remove partial-payment risk, ensuring the transaction rolls back if any single payment method fails. Halfsy does not hold capital itself but passes tokens directly to settlement providers such as Stripe, Adyen, Checkout.com, Braintree, or Worldpay.

Beyond its current division functionality, the team of three employees is building infrastructure for international optimisation and fallback paths via Open Banking and Buy Now, Pay Later (BNPL) services. Services listed in its registration include computer disaster recovery, installation of personal computers, and data archiving. Documentation for the round was filed in July.
