DIESTA

Premium payment operations and reconciliation automation for the intermediated insurance market

Core Administration Startup Seed

Overview

Diesta is a B2B payment operations platform for the intermediated insurance market, serving MGAs, brokers, carriers, and syndicates in the UK and international specialty markets. The platform automates premium payment processing, reconciliation, and sub-ledger management across the insurance distribution chain, replacing manual spreadsheet-based workflows with API-driven automation.

The platform encompasses a reconciliation engine that syncs premium records, bank data, payment service provider transactions, and partner documents; a financial sub-ledger that consolidates data across policy systems and general ledgers; integrated credit control and payment initiation; and Diesta AI for intelligent exception handling. The company holds SOC 1 Type II, SOC 2 Type II, and ISO 27001 certifications and is regulated by the UK Financial Conduct Authority.

Founded in 2022 by Julian Schoemig (CEO) and Christopher Davis (CTO), Diesta has raised approximately USD 5.9M across three rounds, including a USD 3.8M seed round in October 2024 led by FinTech Collective. The company counts INSHUR, Moonrock, and OneAdvent among its customers, and formed partnerships with INSHUR and Concirrus in 2025 for specialty and fleet insurance payment automation.
