Mazlo didn’t come out of stealth to be another fintech costume party. They built the backbone nonprofits have been waiting decades for. Banking, payments, accounting, integrated in a way that respects how mission-driven organizations actually operate. No shoddy spreadsheets, no endless reconciliations, no pretending that nonprofits can thrive on hand-me-down infrastructure. And now they’ve locked down $4.6 million in seed funding, led by Westbound Equity Partners with support from Andreessen Horowitz, Social Good Fund, Super{set}, and a network of angels who recognize the scale of this opportunity.
This story starts with lived frustration, not theory. Co-founder and CEO Kian Alavi spent fifteen years in nonprofit finance at Good Samaritan Family Resource Center. He didn’t invent a problem so he could pitch a solution, he endured the pain of grant reporting, watched staff drown in compliance chaos, and decided the sector deserved better. He teamed up with co-founder and Chief Product Officer Sean Anderson, a fintech product builder with a decade of experience, and together they spent two years in stealth. The result was Mazlo, a platform designed from the ground up for nonprofits instead of retrofitting corporate finance tools.
Results speak louder than decks. Sixty organizations and fiscal sponsors have already onboarded, with more than 1,600 active users across nearly every state. Gross profit climbed 275 percent over the last year with zero churn. Tens of millions in transaction volume have moved through Mazlo, cutting reconciliation workloads by ninety percent. Clients like Good Samaritan Family Resource Center and Homeless Prenatal Program aren’t test pilots, they’re proof of concept at scale.
The differentiator is discipline. Project-specific subaccounts with unique routing numbers enforce restricted funds. Automated transaction coding slashes audit prep time. Smart cards with spending limits and real-time alerts prevent compliance headaches before they start. Dashboards provide audit-ready reporting that regulators and funders can trust. Compliance isn’t bolted on, it’s baked in.
This fresh capital is fuel for expansion. AI-driven reconciliation and predictive cash flow tools are next. A mobile app for approvals arrives later this year. An open API for third-party extensions lands in early 2026. Regional offices in New York, Chicago, and Washington, D.C. are on the roadmap, with a Canadian pilot planned for the back half of 2026. The team will grow from eleven to thirty, scaling engineering, sales, and customer success to meet the demand already knocking at the door.
The nonprofit sector in the U.S. manages more than a trillion dollars every year, yet the financial plumbing behind it has looked like a relic from the dial-up era. Westbound Equity Partners, Andreessen Horowitz, Social Good Fund, and Super{set} are betting on Mazlo because they see what happens when you replace outdated scaffolding with real infrastructure. This isn’t a side project. It’s a correction.
