About Edouard Mascré
Edouard Mascré is a co-founder and Head of Sales (Directeur Commercial) of Pennylane, a Paris-based accounting and financial management software company. Crunchbase and Sequoia list him as a co-founder. Pennylane's investor page names him among its seven founders and says Sequoia has backed the company since 2021.
Before Pennylane he studied at HEC and its HEC Entrepreneurs master's program. According to Pennylane's staff profile and TheOrg, he then worked at Saint-Gobain Distribution Bâtiment France, where he directed the key account business from 2014 to 2018. He did business development at mediarithmics from 2018 to 2020, before moving to Pennylane full time in 2020.
At Pennylane he has run the sales organization since launch. He also talks publicly about selling to accounting firms.
Crunchbase lists him as an individual angel investor based in Paris. It shows one personal investment: a seed round in Dash on March 7, 2022. No check size is disclosed. Public records of his angel activity are thin, so founders should treat this list as incomplete.
His AI investment on the Lounge deals desk is Leadbay, a seed round of $4.3M in May 2026. Leadbay builds AI software for B2B lead discovery and sales prospecting. Maddyness reports that the Paris startup went through Y Combinator (F25 batch) and has opened a San Francisco office.
Maddyness names the round's investors as Y Combinator, Rebel Fund, Progressive VC, Bright Data Ventures, Inovexus, Roosh Ventures and Station F. Business angels in the round include Philippe and Alex Bouaziz of Deel, and Mascré of Pennylane. His check size in the round is not public.
He has no public investment thesis or stated check size. His two known deals are seed-stage rounds in European startups. The Leadbay round targets sales and go-to-market software. His operating background is in B2B software sales, which is where his Leadbay investment sits. He is based in Paris.
