A few billion euros in unpaid invoices flow through Cleavr’s system each year. The Paris-based startup, founded in 2025, is betting that number will grow as its AI takes over one of finance’s most tedious jobs: chasing down late payments [tech.eu, October 2026].
Cleavr calls its product an “AI coworker.” Its job description is narrow. It identifies who to contact about a late invoice, sends reminders via email, SMS, WhatsApp, or even automated phone calls, tracks commitments, and escalates to legal monitoring if needed [Cleavr, retrieved Unknown]. The platform is designed to handle the entire cycle from the day after an invoice is due to pre-litigation, according to the company [LinkedIn, Thibaut GIMENEZ, retrieved 2026]. For finance teams in logistics, manufacturing, and construction, the promise is a 37% reduction in days sales outstanding and 40% more cash collected, based on company-reported figures [Vestbee, October 2026].
The Wedge in European Receivables
The bet is on automation depth, not breadth. Cleavr is not a general ledger or a broad accounting platform. It is a specialized tool for accounts receivable, integrating with a long list of existing financial and CRM systems like Pennylane, Stripe, SAP, and Xero [Cleavr, retrieved Unknown]. The company claims its AI learns from each interaction, maintaining a memory of each debtor’s payment habits and preferred communication channels to improve future reminders [LinkedIn, Thibaut GIMENEZ, retrieved 2026]. This focus on a single, painful workflow is its wedge into the finance department.
Traction, so far, supports the focus. Cleavr reported having approximately 50 customers by March 2026 [JDN, March 2026]. Seven months later, that count had crossed 100, spread across France, Spain, Germany, Belgium, Italy, and the United Kingdom [Tech Funding News, October 2026]. The company also claims to have recorded 0% customer churn since its launch [The Paypers, October 2026]. While these are company-reported metrics, the geographic spread suggests the platform’s multi-language, cross-border support is finding a market.
The Team and the Capital Stack
The founding trio brings a mix of venture, operational, and professional services experience. CEO Baptiste Nassoy was previously an analyst at Kima Ventures, an early investor. Co-founder Arthur Guérin has a background at mobile gaming studio Voodoo, and Antoine Grenard worked at PwC [Perplexity Sonar Pro Brief, Unknown]. Their network helped assemble a seed round that reads like a who’s who of French fintech angels.
Cleavr’s funding journey moved quickly. A €1 million pre-seed round in March 2026 was led by Kima Ventures and included angels from companies like Pennylane and MyUnisoft [Cleavr, March 2026]. Just six months later, the company closed an €8 million seed round led by Varsity. The syndicate included previous backers and new names like Portfolio Ventures and Financière Saint James [Vestbee, October 2026].
| Round | Date | Amount | Lead Investor |
|---|---|---|---|
| Pre-seed | March 2026 | €1 million | Kima Ventures |
| Seed | October 2026 | €8 million | Varsity |
Where the Model Faces Friction
No automation platform operates in a vacuum. Cleavr’s growth depends on convincing finance leaders to hand over a sensitive, relationship-driven process to software. The risks are not hypothetical.
- Proven scale. The public results show traction in the low hundreds of customers. The real test is whether the AI’s effectiveness and the reduction in manual work, claimed to be 80%, hold true as Cleavr onboards larger, more complex enterprises with thousands of invoices [LinkedIn, Guillaume Duvaux, retrieved 2026].
- Competitive density. The space for AR automation is not empty. Cleavr lists competitors like Upflow and LeanPay. Differentiation will hinge on the sophistication of its AI-driven workflows and the breadth of its European legal and payment integrations.
- Economic proof. The cited metrics on DSO reduction and cash collection are powerful, but they are self-reported by the company. Independent case studies or audited results from named enterprise customers would strengthen the value proposition for larger deals.
The company’s answer is its integrated, end-to-end approach and the reported zero churn. If the product works as advertised, the cost of switching back to a manual process is high.
The Next Twelve Months
The fresh €8 million gives Cleavr runway to scale. The immediate priorities are clear: deepen its footprint in its existing six European markets and likely expand into new ones. Key hires in sales and customer success will be critical to managing growth beyond 100 customers. Another milestone to watch is the launch of partnerships or embedded solutions with larger financial platforms, leveraging its existing integrations.
The seed round from Varsity and the continued backing from Kima Ventures signal investor confidence in the team’s focused execution. For now, the question for European finance teams is straightforward: is an AI coworker dedicated to your unpaid invoices worth the subscription? Cleavr’s growing customer list across the continent suggests a growing number are answering yes.
