What Diesta does
Diesta is a London-based B2B insurtech founded in 2022 that provides a cloud-native payment operations platform for the commercial insurance industry. The company automates premium reconciliation, sub-ledger accounting, and payout processing for MGAs (Managing General Agents), brokers, and insurers, addressing structural inefficiencies such as slow settlement cycles, aged debt, and unallocated cash in intermediated insurance distribution. Its modular platform comprises four components: a Receivables module covering reconciliation, credit control, broker statement generation, instalment management, and multi-currency FX; a Sub-Ledger module providing event-driven trial balance functionality with push integrations to NetSuite, Oracle, and Sage; a Payouts module for scheduling and execution of outgoing payments including commissions, reinsurance premiums, and insurer charges; and Diesta AI, embedded across modules for reconciliation matching, document standardisation, and payout optimisation.
The platform is built on Node.js and TypeScript on AWS with an event-driven architecture, particularly within the sub-ledger, for real-time visibility. Diesta integrates directly with seven major banks (Lloyds, Barclays, Citi, UBS, DNB, DBS, HSBC) for payment initiation and with PAS providers (Verisk, Instanda, Concirrus) for upstream policy data. The company is certified to SOC 1, SOC 2 Type 2, ISO 27001, GDPR, and ISO/IEC 42001 (AI governance) and operates as an FCA-regulated agent via Plaid Financial Ltd.
Diesta monetises through annual tiered subscriptions (Essential, Professional, Enterprise) with quote-based pricing scaled to transaction volumes, users, and partners. Go-to-market is sales-led with direct enterprise sales targeting insurers, brokers, and MGAs, supplemented by technical partnerships with PAS providers that create pull dynamics, and event presence at insurance industry conferences. As of early 2026, Diesta reported 25 staff, 25 clients, approximately 3,000 organisations connected, and revenue in the mid single-digit millions, with planned investment in go-to-market scaling and the 2026 launch of the Diesta Network module.

Diesta competitors and assessment
Company assessmentDirect peers
- OneInc: OneInc is a payment processing and digital communications platform built specifically for the insurance industry, providing premium payment, agent commission, and claims payment solutions — directly comparable to Diesta's premium payment operations focus.
- Modern Treasury: Modern Treasury provides a payment operations platform with reconciliation, ledgering, and embedded payment initiation for businesses. While vertical-agnostic, its core capabilities in reconciliation and money movement mirror Diesta's stack and represent a credible cross-vertical competitor.
Others
- Plaid: Plaid is the financial data connectivity and account information services platform through which Diesta accesses bank data (Diesta operates as an agent of FCA-regulated Plaid Financial Ltd). It is a critical infrastructure partner rather than a direct competitor.
- Verisk: Verisk is a data analytics and insurance industry solutions provider, and a current PAS partner of Diesta. It is relevant as both a partner in Diesta's channel strategy and an incumbent with the data and scale to develop competing capabilities.
Emerging players
- Socotra: Socotra is a cloud-native insurance core platform targeting modern insurers and MGAs with policy administration and billing. It competes in adjacent layers and represents the kind of modern PAS that could either partner with Diesta or build competing payment functionality.
- Finix: Finix is a payment infrastructure platform enabling businesses to orchestrate money movement, ledgering, and reconciliation. Like Diesta, it focuses on operational payment workflows, though Finix is vertical-agnostic and serves platforms rather than insurers specifically.
Broad incumbents
- EIS Group: EIS provides a core insurance platform with policy administration, billing, and claims capabilities for global insurers. Its billing and payment modules overlap with Diesta's scope, particularly in complex commercial insurance distribution chains.
- Majesco: Majesco is a long-standing insurance software provider offering policy, billing, and claims platforms for P&C and L&A insurers. It overlaps with Diesta in the billing and payment operations layer for mid-market and enterprise insurers.
- Duck Creek Technologies: Duck Creek is a major insurance core platform serving P&C insurers with policy administration, billing, and claims. It overlaps with Diesta through billing and payment workflows for insurers and represents the type of incumbent that could build native payment features.
- Guidewire Software: Guidewire is the dominant insurance core platform for P&C carriers, offering policy, billing, and claims management. It overlaps with Diesta in the billing/payment area and serves many of the same insurer customers, making it a relevant incumbent comparison.
