Remitian, a Miami-based fintech startup focused on modernizing tax payment infrastructure for accounting firms and financial software platforms, has raised $7 million in a seed funding round aimed at scaling its API-first payments execution system and expanding its integrations across the professional services ecosystem.

The company operates in the tax remittance infrastructure space, targeting what it identifies as a persistent gap in financial workflows: while tax preparation and filing are increasingly digitized through accounting software, the actual payment of taxes to multiple jurisdictions remains fragmented, manual, and error-prone. Remitian’s platform addresses this by enabling users to initiate, validate, execute, and track tax payments directly within existing accounting or enterprise systems, reducing reliance on spreadsheets, bank portals, and manual reconciliation.

The seed round was led by Cambrian Ventures, an early-stage venture firm focused on fintech infrastructure. Additional institutional participants included Garage Capital, N49P Venture Capital, Aprio, HubSync, and Aiwyn. The round also included participation from industry operators and fintech leaders such as Daniel Eberhard, Richard Kopelman, Ryan Lazanis, and Rex Salisbury.

Remitian’s leadership stated that the newly raised capital will be deployed toward accelerating product development, expanding engineering capacity, and strengthening go-to-market initiatives across North America. A key priority is deepening partnerships with accounting firms, enterprise finance teams, and software providers that require embedded tax payment functionality as part of broader compliance workflows. The company’s infrastructure is designed to support real-time payment initiation, jurisdiction-specific routing logic, and audit-ready logging, all accessible via APIs and embedded software modules.

Founded in 2024, Remitian is led by CEO Solon Angel, who previously founded the AI-driven audit analytics company MindBridge. Under his leadership, Remitian has positioned itself as a developer-centric infrastructure layer rather than a standalone tax application, offering APIs that allow software platforms to embed tax payment functionality directly into their existing user experience. This approach reflects a broader fintech trend toward modular financial infrastructure that can be integrated into vertical software systems.

The company reports that its platform is already processing more than $100 million in tax payments, with early adoption from accounting firms including Aprio. Early users have emphasized improvements in operational efficiency, particularly in reducing manual reconciliation steps, minimizing payment errors, and improving visibility into tax obligations across multiple jurisdictions. By centralizing payment execution, Remitian aims to reduce the operational overhead typically associated with compliance-heavy financial workflows.

Investors in the round are betting that tax payment execution remains one of the most underserved layers in financial infrastructure. While significant innovation has occurred in tax preparation software, payroll systems, and accounting automation, the final step of moving funds to tax authorities has remained relatively unchanged for decades. Remitian’s model seeks to bring the same level of automation, traceability, and programmability to tax payments that has already transformed broader payments infrastructure in fintech.

The company also sees opportunities beyond traditional accounting firms, including expansion into wealth management platforms, payroll providers, and enterprise resource planning systems that require embedded compliance capabilities. By positioning itself as an infrastructure provider rather than a point solution, Remitian aims to become a backend layer powering tax payments across multiple financial software categories.

With fresh capital in place, Remitian is expected to accelerate hiring, expand integrations with major accounting ecosystems, and scale its operations across the United States and Canada. As regulatory complexity increases across jurisdictions, demand for automated, audit-compliant payment infrastructure is expected to grow, providing a potential tailwind for the company’s expansion strategy.
