Overview

Tranch was a B2B payments fintech founded in 2021 by Philip Kelvin and Beau Allison, both alumni of UK proptech startup Trussle. Operating out of London and New York, the company built an invoice-to-payments platform targeting enterprise buyers and sellers — initially across SaaS and professional services broadly, then narrowing to law firms specifically. It raised approximately $104M across five rounds, including a $95M debt facility to fund its lending book, and participated in Y Combinator's Summer 2022 cohort.

Tranch did not fail. It executed a deliberate ICP narrowing from broad B2B BNPL into legal-sector invoice payments, built a defensible position with marquee law firm clients, and was acquired by Elite — the dominant financial management software provider for large law firms — on January 3, 2025.

The acquisition price was not disclosed, making it impossible to assess investor returns against the ~$104M raised. But the strategic logic was unambiguous: Tranch had become the payments layer that Elite's existing software stack was missing, and the 3x payment volume growth in 2024 gave Elite a reason to buy rather than build.

Founding Story

Tranch was founded in 2021 by Philip Kelvin and Beau Allison, two operators who had worked together at Trussle, a UK digital mortgage broker.^[1] Kelvin had served as CFO at Trussle; Allison as Head of Engineering.^[1] The pairing was complementary in the way that matters for fintech: one founder who had lived the financial operations problem firsthand, and one who could build the infrastructure to solve it.

Kelvin's background before Trussle included investment banking, management consulting at Bain & Company, and an MPhil from the University of Cambridge.^[3] Allison brought full-stack engineering experience from IBM and Trussle.^[4] The founding insight was not abstract — it came directly from Kelvin's time managing a scaleup's finances.

"Tranch was born out of a frustration and desire to fix a broken model," Kelvin said at the pre-seed launch. "My time as a scaleup CFO made me realise just how inflexible payment options can be for crucial SaaS tools and other business services."^[5]

The specific friction Kelvin had experienced: large invoices — for SaaS subscriptions, legal services, consulting engagements — typically required full upfront payment or rigid net-30/60/90 terms. Buyers with strong creditworthiness but lumpy cash flows had no good option. Sellers, meanwhile, faced delayed cash collection and the administrative burden of chasing receivables. Neither side was well-served by the existing infrastructure, which still relied heavily on checks for settlement.^[33]

The company was incorporated with deliberate transatlantic structure from the outset: Zero Degrees Holding Company Limited in the UK and Tranch, Inc. in Delaware.^[2] This dual structure — with the UK entity registered with the FCA — was not an afterthought expansion but a signal of ambition to operate in both markets simultaneously.

Tranch was selected for Y Combinator's Summer 2022 cohort,^[6] which provided the brand credibility and investor network access that accelerated the US market entry. The YC program also coincided with the company's public launch and pre-seed announcement in May 2022.

The precise moment the founders decided to narrow from "B2B BNPL for all SaaS and services" to "invoice payments for law firms specifically" is not documented in public sources. What is clear is that the Goodwin law firm partnership in November 2022 — just six months after launch — was the first major signal that legal services was a particularly receptive vertical, and the company's subsequent product and sales investments followed that signal.
