About End Close

GPAgent's own fund-neutral profile, written from public information. Updated Oct 4, 2026.

Summary

End Close builds automated reconciliation software for high-volume payments companies: fintechs, marketplaces, banks, and payroll providers. It replaces manual exception handling and end-of-month close work by continuously matching transactions across exact, fuzzy, and many-to-many patterns, then deploying AI agents to investigate and resolve discrepancies without human intervention. Finance and payment operations teams get an always-current audit trail and real-time position data they can expose directly inside their own products.

Go-to-market

B2B buyers are finance and payment operations leaders at fast-growing payments companies who would otherwise build reconciliation in-house or inherit a legacy system. Sales is demo-led, with developer-friendly APIs designed to reduce integration time from quarters to weeks.

AI powered reconciliation for high-volume payments companies

End Close builds automatic reconciliation for payments companies like fintechs, marketplaces, banks and payroll companies. Reconciliation helps companies track every dollar and resolve every exception, ensuring they have no money loss, can report audit ready financials, and stay compliant. Sean (CEO) spent the last 6 years building the reconciliation org at Modern Treasury (S18), processing a trillion dollars in payments across 40 banks with 99.995% automation. Fast growing companies like Modern Treasury are forced to build a solution in-house or buy a legacy solution. End Close provides a modern reconciliation system that works with a company's existing stack and is managed by AI agents. Exception handling is where 99% of the manual work happens today, payment ops teams spend hours gathering context across various data sources to investigate each ticket. End Close provides an AI ops agent that connects to a company's data warehouse, invoicing platform and payment processors to triage and resolve issues without human intervention. Legacy providers only provide reconciliation for month end close applications. End Close continuously reconciles with developer friendly APIs, allowing teams to integrate real time payments data within their products to create product experiences for customers like faster balance top-ups, instant trading etc. New payment rails and agent-to-agent payments are increasing online transaction volumes, making reconciliation a growing challenge for companies. David (CTO and 2nd time YC founder) most recently built these kinds of high-scale ingestion pipelines when starting and leading error tracking at PostHog (W20), the fastest growing product in the company's history.
