Tabs, the pioneering AI-native revenue platform for modern finance teams, has secured $55 million in Series B funding led by Lightspeed Venture Partners, with participation from General Catalyst, Primary Venture Partners, and WiL (World Innovation Lab). This round brings Tabs' total funding to over $91 million, fueling expansion of its agentic AI tools that automate the contract-to-cash cycle amid a $125 trillion global B2B transactions market.
Despite advances in payments and payroll, revenue processes—billing, collections, recognition, and reporting—lag with manual ERPs, spreadsheets, and point solutions, consuming up to 50% of finance time and yielding 20% invoice errors. This delays cash flow and revenue, exacerbated by complex pricing models and a shrinking accounting workforce. Tabs' platform counters these by ingesting contracts to automate invoicing, dunning, reconciliation, and ASC 606 compliance, syncing with CRMs and ERPs for real-time accuracy.
Launching now, Billing Agents analyze contracts, generate/send invoices, and integrate with CRM/ERP systems. Collections Agents track due dates, match payments automatically, and handle reconciliations, reducing errors and accelerating cycles. These agents build on Tabs' foundation, enabling finance teams to focus on strategy amid rising automation demands from CFOs facing headcount constraints.
“Revenue in is the hardest and most valuable workflow in the enterprise, yet finance teams are still stuck with legacy ERPs,” said Ali Hussain, CEO and co-founder of Tabs. “Tabs is bringing modern AI agents to the CFO’s office, starting with billing, complex enterprise contract management, and collections, so companies can collect cash faster and reduce time spent on manual work.”
“Tabs is fundamentally changing how finance teams work, eliminating manual processes that have plagued revenue workflows for decades,” said Justin Overdorff, Partner at Lightspeed Venture Partners. “The team has combined deep finance expertise with purpose-built AI agents for revenue processing and tracking, and the rapid customer adoption we're seeing validates just how ready the market is for this transformation.”
Tabs' rapid traction—5X ARR growth and $500M+ automated volume—signals market readiness for AI in revenue ops. The funding will scale engineering and research in New York, prioritizing agentic innovations to serve high-growth tech and B2B firms navigating fragmented tools and talent gaps.
This Series B validates Tabs' role in fintech evolution, where AI addresses inefficiencies in a trillion-dollar B2B space. By automating overlooked workflows, Tabs empowers finance leaders to unlock cash flow, ensure compliance, and drive strategic value, positioning the platform as essential for scalable growth.
