Sequence secures $20M Series A to Build AI Agents that Automate Revenue Operations

Sequence today announced a $20M Series A led by 645 Ventures, alongside a16z, Firstminute Capital, Passion Capital, Dig Ventures and Vor Capital. A group of world class founders and execs including the CFOs at Decagon, Klaviyo and Wise also joined the round. The new financing comes after a year of 10x ARR growth, driven by mid-market and enterprise companies like Cognition, Legora, Bridge, 11x, and Incident.io choosing Sequence to automate revenue operations. Sequence has raised $40M to date and will use the new capital to accelerate investment on their agent roadmap to eliminate manual finance work, expanding both the engineering and go to market teams. 

Despite innovation in spend management, payroll and payments in the last decade, revenue workflows (billing, collections, revenue recognition) have lagged behind. Finance teams rely on spreadsheets, manual processes, and fragmented tools that struggle with custom deals and modern pricing models. While traditional platforms lock teams into 12-month implementations and inevitably turn into internal engineering projects, Sequence deploys in days, not quarters, and adapts instantly to any pricing structure. 

“I started Sequence after a decade watching finance teams face an impossible choice: drown in manual billing work or rely on systems that break when sales teams close custom deals,” said Riya Grover, CEO of Sequence. “Here’s what’s happening in finance teams – brilliant people spend 80% of 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 shouldn’t be constrained by what the billing engine can support. With Sequence, teams can price and sell in the way that’s best for customers and the business, while Finance has peace of mind knowing every contract, no matter how custom, is handled accurately.”

Sequence was founded by a team of repeat, exited founders, who saw this problem first hand in previous software companies they built and scaled. Legacy platforms didn’t cut it, which is why we built Sequence differently. We started with a foundational data model to handle any pricing model or bespoke contract structure, such as usage tiers, seat overages, complex ramps, and temporary discounts. Then we deployed AI strategically to automate tedious tasks, like contract intake and invoice review, while keeping billing math fully deterministic and finance teams in control. 

The result is the leading AI-first revenue platform designed to consolidate and automate operations across the entire contract-to-cash cycle. Sequence’s AI agents act as a co-pilot for human operators: 

• Contract agent: Converts signed contracts into automated billing and invoicing schedules, all synced with the CRM and ERP. 
• Dunning agent: Automates follow up communications and reconciles payments., 
• Invoice review agent: Detects anomalies and variances before invoices are sent. 

Sequence has built a “watchtower” command centre to give full oversight of all agent activity, and allows easy handoff between human operators and AI, giving finance teams confidence that automation never sacrifices accuracy or control.

Over the last year Sequence has scaled to 100+ customers, achieved 10x ARR growth, and now automates over $1bn in annual invoice volume for companies like Incident.io, Bridge, Legora, Runway, Cognition, 11x, Raspberry AI, Moonpay and Bill.com. Sequence has eliminated the most manual and painful parts of revenue operations from billing and invoice automation to real-time revenue recognition, turning days of work into an automated workflow. 

“I’ve been pushing to move away from Stripe Billing for a long time. We evaluated other billing and contract-to-cash platforms, but none of them offered the billing flexibility required for our custom contract terms. Since adopting Sequence, we’ve cut our monthly billing time from 3 days to <2 hours, and more importantly, have recovered hundreds of thousands in revenue that was sitting in contracts previously too complex to bill manually.” said Billy Motherway, Arch

This is just the beginning. The Series A raise allows Sequence to invest deeply in advancing agentic automation across financial operations, targeting the $165B+ order-to-cash market—a category overdue for disruption where AI enables workflow consolidation and automation. Our vision remains clear: empower finance teams with AI co-pilots that increase efficiency while maintaining 100% accuracy—no black-box solutions, just deterministic, reliable outcomes.

Sequence’s rapid momentum comes from a relentless focus on building exceptional products in close partnership with customers. Today, Sequence powers some of the world’s fastest-growing companies, giving finance teams control over revenue and time back for high leverage work. Sequence delivers what finance teams actually need: a platform that supports complex, custom pricing without breaking, with AI deployed where it truly adds value—accurate by design, intelligent when helpful, and with humans in control. That’s why Sequence is becoming the default choice for next-generation finance teams, moving away from outdated tools.

“Sequence is transforming revenue operations with AI that’s fast, accurate, and flexible enough for any contract,” said Nnamdi Okike & William Hess of 645 Ventures. “Their approach finally gives finance teams the control and efficiency they’ve been waiting for, while adapting to the most complex deals. We’re excited to support Riya and the team as they scale Sequence into the category-defining platform for revenue operations.”
