Mendel secures $50M Series B to scale expense automation across LATAM
Argentine fintech Mendel has raised approximately $50 million to expand its corporate expense management platform throughout Latin America. Founded by Alan Karpovsky and Alejandro Zecler, the company evolved from a corporate card competitor into a B2B SaaS platform automating expense, travel, and invoice management for enterprises.()
The funding sequence included Y Combinator participation, a $3 million seed round, a $15 million Series A, and a $35 million Series B led by Base10 Partners with participation from PayPal Ventures and other investors.
Mendel operates across Mexico, Argentina, and Chile with roughly 1,500 corporate clients: approximately 1,100 in Mexico, 350 in Argentina, and 50 in Chile. Major customers include Mercado Libre, FEMSA, McDonald's, and Vista Energy, with approximately 250,000 employees using the platform.
The company's strategic pivot came after recognizing that competing with American Express on payment infrastructure was not viable. Instead, Mendel targeted the persistent manual work: Excel spreadsheets, email chains, and cash handling for corporate advances, per diems, invoices, and travel. The platform integrates expense management, payments, and travel tools to give finance teams real-time visibility into spending, compliance, and transaction details.

Why Vaca Muerta and enterprise growth demand specialized finance and operations talent
Argentina's Vaca Muerta energy basin is creating distinct operational demands for corporate expense automation and, by extension, new workforce planning challenges for companies building finance and operations teams in Argentina. The energy sector requires daily mobilization of thousands of workers and administration of lodging, transportation, meals, work clothing, and equipment expenses.
Vista Energy already uses the platform. Mendel reports growing opportunities with foreign companies entering the basin, including a Mexican construction firm that won a Vaca Muerta contract and needs to relocate approximately 3,000 employees to Argentina. Managing expense workflows, compliance, and financial controls for a cross-border workforce of that scale demands both technology infrastructure and specialized finance and operations personnel.
This pattern extends across mining, construction, and logistics. As operations become more geographically dispersed and financially complex, employers increasingly seek finance professionals who understand local compliance requirements and enterprise software implementation, along with operations managers capable of overseeing distributed teams with real-time financial oversight.
Mendel's client base reflects broader enterprise digitization across LATAM. Companies like Mercado Libre and FEMSA operate at significant scale, and their adoption of automated expense management signals a maturation of corporate finance functions. These sectors increasingly need talent with experience in financial controls, ERP integration, policy enforcement, and data analysis.
The fintech's partnership model further illustrates the evolving talent landscape. In Argentina, Mendel works with Banco CMF; in Chile with Banco BICE. Its software integrates with cards issued by multiple institutions, positioning the company as a technology layer rather than a direct banking competitor. This approach requires technical talent capable of API integration, compliance engineering, and multi-jurisdictional financial operations.
Fintech expansion signals emerging hiring needs in Argentina's energy and corporate sectors
Mendel reports achieving profitability after four and a half years of operation and projects closing 2026 with approximately 500 large clients in Argentina. The company notes increased interest from foreign companies and investors in the Argentine market, a trend with implications for cross-border hiring and scaling talent across Mexico's fintech sector and beyond.
B2B fintech platforms in LATAM reflect a structural shift in how enterprises manage financial operations. While consumer-focused fintechs dominated early investment cycles, corporate clients still maintain significant manual processes. Mendel's traction with large enterprises suggests that finance and operations roles will increasingly require familiarity with SaaS platforms, automated workflows, and real-time reporting tools.
For energy sector employers, Vaca Muerta's development creates acute needs for finance and HR professionals who can manage large, mobile workforces under complex regulatory and logistical conditions. Relocating a large workforce involves not only expense management but also payroll, benefits, housing, compliance, and cross-border tax considerations. Companies operating in or entering the basin will need bilingual finance managers, compliance specialists, and HR operations leads with experience in remote and high-turnover environments.
The fintech's revenue composition signals hiring trends. With SaaS subscriptions representing more than half of income, Mendel's business model depends on customer success, implementation, and support teams. As the platform scales, demand will grow for customer success managers, technical account managers, and implementation consultants working directly with CFOs, controllers, and finance operations teams.
Operating across three countries requires navigating distinct tax regimes, labor laws, and banking regulations. Employers in fintech and corporate services sectors will need legal, compliance, and finance professionals with multi-country expertise and the ability to adapt platforms and processes to local requirements.
Mendel's backing by Base10 Partners and PayPal Ventures positions it within a broader LATAM fintech ecosystem.() As more platforms achieve scale and profitability, competition for experienced fintech talent will intensify, particularly for roles in product management, engineering, sales, and finance operations. Employers will need to offer competitive compensation, remote work flexibility, and clear growth paths to attract and retain professionals in this rapidly evolving sector.
