Rivage raises €1.5 million to automate the back office of French rental agencies with AI

Rivage, a Paris proptech founded in 2025, has raised a €1.5 million Seed round led by Kima Ventures, with participation from a group of strategic angels: Nicolas Goyet (founder of Flatlooker, now board member), Gérard Deray, Jean Boucher (Mila), and Quentin de Metz (co-founder of Pennylane). The company was founded by Alex Chauvin (CEO), Antoine Barranco (COO), and Grégory Prève (CTPO) and builds AI-powered rental agency management software — a platform that combines a modern rental accounting engine with an integrated AI agent that automates billing, service charge calls, bank reconciliation, and client communications.

Two weeks after Amsterdam's HousApp closed its Seed round on the same admin-automation premise — taking the overhead out of property transactions — a second proptech built around the same thesis arrives in Paris, this time targeting the back office of rental agencies rather than the transaction process itself.

The administrative overhead embedded in French rental management

French rental agencies face a structural cost problem with a precise metric: one additional employee for every 200 managed units managed. Net margins in the sector run at 10–13%, roughly half those of comparable professional services businesses, and the overhead that compresses them is well understood — billing, service charge reconciliation, bank transaction matching, and client communications each individually manageable but collectively consuming most of the operational capacity of running an agency.

Rivage's AI agent automates them. The company claims up to 95% automation on specific workflows, shifting the human role from doing to checking. The early traction is notable: hundreds of agencies on the platform and €200,000 in ARR reached within a few months of commercial launch, across neo-agencies, franchisee networks, and national chains.

The platform also implements MCP (model-context protocol) connections, enabling agencies to feed their data directly into Claude, ChatGPT, or other AI tools for custom workflows — a technical choice that positions Rivage as an infrastructure layer rather than a closed application.

The angels matter here

The angel line-up is directionally significant, not just decorative. Nicolas Goyet built Flatlooker, which subsequently merged with Hello Syndic to form Manda — one of Rivage's named competitors — and brings first-hand knowledge of the market's dynamics. His stated conviction: their product is already more complete than that of their established competitors. Quentin de Metz co-founded Pennylane, the French accounting SaaS that has scaled rapidly in the SME market; he is a structural reference point for what Rivage is attempting — roughly the same move for rental agencies that Pennylane made for general SME accounting.

Chauvin frames the fundraise as a deliberate acceleration: "We didn't need to have a fundraiser to pursue Rivage, but we wanted to accelerate and nurture the advantage that we have against our competitors in France." The advantage he is referring to is local: French and Eastern European rental accounting standards are specific enough that American SaaS companies find them difficult to replicate without French-native R&D. The Seed goes to doubling the team, deploying the AI agent more broadly, and targeting €5 million ARR by 2027 from the current €200,000 base.
