£15.0MSeries A

Sequence provides an AI powered revenue platform designed to automate operations across the contract to cash cycle for modern finance teams. The software handles complex pricing models and custom contracts while eliminating manual tasks through dedicated agents.

Sequence has raised £15m in a Series A funding round led by 645 Ventures. The capital injection also saw participation from a16z, Firstminute Capital, Vor Capital, Passion Capital, and Dig Ventures, alongside several prominent founders and executives.

The new funding follows a period of rapid growth for the company, which has seen its annual recurring revenue multiply tenfold over the past year. Sequence plans to direct the proceeds towards accelerating its agent roadmap and expanding both its engineering and go to market teams to support scaling operations.

From the founder

"I started Sequence afiter a decade watching fiinance teams fiace an impossible choice: drown in manual billing work or rely on systems that break when sales teams close custom deals. Hereʼs whatʼs happening in fiinance teams – brilliant people spend 80% ofi their time on repetitive tasks like calculating invoices by hand, chasing unpaid bills, and reconciling transactions, while revenue slips through the cracks because complex contracts are hard to track. Sales shouldnʼt be constrained by what the billing engine can support. With Sequence, teams can price and sell in the way thatʼs best fior customers and the business, while Finance has peace ofi mind knowing every contract, no matter how custom, is handled accurately."

Investor perspective

"Sequence is transfiorming revenue operations with AI thatʼs fiast, accurate, and filexible enough fior any contract. Their approach fiinally gives fiinance teams the control and efifiiciency theyʼve been waiting fior, while adapting to the most complex deals. Weʼre excited to support Riya and the team as they scale Sequence into the category-defiining platfiorm fior revenue operations."
