Pennylane raises €175m as French accounting platform nears €3.5bn value

Pennylane has raised €175m in a funding round that values the Paris-based accounting and banking platform at roughly €3.5bn. The round, announced in January, was led by two new investors, TCV and Blackstone Growth, with existing backers Sequoia Capital, DST Global, CapitalG and Meritech Capital also putting in money.

The raise marks a sharp jump from Pennylane's last outing. In February 2024 the company took in €40m at a valuation near €1bn. Less than two years later, that figure has more than tripled, a sign of how quickly the French fintech has scaled since reaching unicorn status.

What the money is for

The company plans to spend the capital on three things: expanding its artificial intelligence features, building out electronic invoicing infrastructure, and pushing further into other European markets. The company has been developing an AI "co-pilot" meant to support accountants and financial advisers with client work rather than replace them.

The e-invoicing piece carries particular urgency. France is phasing in mandatory electronic invoicing for businesses starting in 2026, and Pennylane has said it wants to walk its customers through that transition. For a platform built around linking SMEs with their accountants, a regulatory deadline like this is as much an opportunity as a compliance headache, and getting ahead of it could lock in more firms before rivals catch up.

By the company's own count, roughly 6,000 accounting practices and 800,000 smaller European businesses now run on the platform. Pennylane employs about 1,000 people, with close to half of them working in research and development, underlining how much of the business is still being built out on the product side rather than sales.

Founders keep the wheel

Unlike many startups that trade more control for growth capital, Pennylane structured this round to keep founders in charge. The company said governance stays under its existing charter, with the founding team retaining control, and it committed to no price increases and no change in product strategy as part of the deal.

Arthur Waller, Pennylane's co-founder and chief executive, framed the round as opportunistic rather than necessary.

"We had no immediate need for funding, but the opportunity to partner with investors like TCV and Blackstone with low dilution was a strategic advantage," Waller said. "This gives us the resources to stay fully independent while accelerating our lead in AI and expanding across Europe. Our mission remains unchanged: being the reference tool for accountants and their clients."

That low-dilution framing matters for a sector where founders often watch their stakes shrink with each large check. It also suggests Pennylane had the upper hand going into talks with two new institutional investors eager to get into the deal.

A crowded field, a bigger wallet

The company operates in a market where legacy accounting software makers and newer fintech challengers are both racing to bundle invoicing, banking and bookkeeping into single platforms for small businesses. The scale of this round, and the valuation that comes with it, gives Pennylane more room to outspend smaller rivals on both AI development and country-by-country expansion across Europe.

Founded in Paris in 2020 by Arthur Waller and his co-founders, the company built its product around giving business owners and their accountants a shared, real-time view of invoices, bank flows and financial reporting. That approach helped it reach unicorn status in 2024, and this latest round pushes its valuation well past that mark.

What happens next will depend partly on execution around the French e-invoicing rollout, a deadline that will test whether Pennylane's infrastructure can handle a wave of mandatory adoption without disruption for its accounting-firm customers. The company has not detailed specific expansion targets beyond saying it intends to move into additional European markets.
