Two Alan Alumni Raise $3M for Outline, Betting Backtested AI Can Finally Kill the Finance Spreadsheet

Outline, a Paris based startup building AI agents for finance teams, has raised 3 million dollars in seed funding to save finance teams the roughly four days per month they typically spend reconstructing forecasts in Excel, replacing that manual process with an AI agent built to carry out the task itself.

Founders Future led the round, with 100in, Newschool, and a group of finance‑industry angel investors also participating, including Bruno Vaffier, chief executive of Cegid, Antoine Lizée, the AI leader at Alan, and Raphaël Nahum, finance director at Pennylane. Speaking with Tech Funding News, co‑founder Antoine de Mereuil said the round closed quickly once early investors committed, noting that what interests venture capitalists most is founder experience and the size of the underlying market. "We had a number of funds to choose from, and our aim was to pick the best partners," de Mereuil said.

The company was founded by de Mereuil and Hubert J, who met while both working at French health insurance company Alan in 2020 and spent several years refining their idea before formally launching Outline. Jaouen, a graduate of École des Ponts and the London School of Economics, worked in data and finance at Spotify across both New York and San Francisco before becoming financial planning manager at Alan. De Mereuil brings a background spanning multiple ventures: he founded and sold several companies, held sales roles at Frichti and Alan, and built Primo into a 40‑person SaaS company before serving as chief financial officer across his various ventures. "We had been thinking about setting up something jointly for some time," de Mereuil said. "But when the shift to AI took place, it was exactly the right moment to go ahead and build it."

Outline has deliberately kept its team small, consisting of de Mereuil, Jaouen, and one product engineer, with plans to hire four additional people using the new capital. The company is targeting a financial planning software market that Technavio projects will exceed 7 billion dollars in 2026, growing at nearly 14 percent annually, even as tens of thousands of medium‑sized companies across Europe and the United States continue running core financial operations on spreadsheets rather than dedicated software. De Mereuil pointed to France's compulsory e‑invoicing reforms and a difficult broader economic environment as additional pressure pushing CFOs to take on a more strategic role rather than remaining focused purely on closing the books.

The obvious question facing any company handing forecasting work to an AI agent is what happens when the agent gets it wrong. De Mereuil's answer centers on a backtesting process built directly into Outline's architecture: the system pulls data from a company's CRM, ERP, and bank accounts, then simulates the forecasts the model would have generated three months earlier and compares those simulated forecasts against what actually happened, before the agent is permitted to generate live, forward‑looking predictions. "All the logic is contained in the code," de Mereuil said. "You don't just ask Claude a question and then hope for a good answer." On the broader question of AI hallucination, he was candid that it remains an issue but said Outline is seeing fewer of them over time, citing a recent comment from Bill Gates suggesting the industry‑wide hallucination problem is fading. De Mereuil's own view is that verticalisation, rather than general‑purpose AI capability alone, is what actually solves the reliability problem, drawing a direct comparison to how narrowly focused AI tools have found more durable traction in legal work than broad, general‑purpose assistants.

Following preliminary conversations with chief financial officers in March and April 2026, Outline secured 10 paying design partners, including restaurant technology company Zelty, cap table platform Shares, and cybersecurity firm HarfangLab, and is aiming to add another 10 customers by the end of September.

De Mereuil argues the competitive landscape is considerably less crowded than it might first appear. Companies with revenue below 5 million euros generally don't yet need dedicated financial planning and analysis tools, he said, while companies above 150 million euros in revenue typically already rely on established enterprise players such as Pigment, Anaplan, and Workday. "We don't actually have any competitors in that sector since most of these companies carry out their financial planning in Excel," de Mereuil said. "The only real competitors today are companies which are just as small and new as we are, not large existing firms that have been in the business for twenty years." Founders Future partner Louis Sautet echoed that framing, describing financial planning as one of the most strategic activities inside a company and one of the last areas AI has not yet meaningfully reinvented, adding that "Hubert and Antoine bring the dual product‑and‑finance culture that this market requires."

Outline's raise arrives as European finance software more broadly leans harder into AI. French accounting unicorn Pennylane raised 200 million dollars in January 2026 specifically to advance its move into AI‑powered bookkeeping, while at Cegid, where angel investor Vaffier now serves as chief executive, generative AI has become a central pillar of company strategy. With its new capital split between product and go‑to‑market hiring, Outline plans to expand its current base of French customers into the broader European market and the United States, betting that its backtesting‑first approach to AI forecasting gives it a credibility edge with finance teams who remain understandably cautious about handing over control of a process as consequential as financial planning to an autonomous system.
