Why We’re Backing Tabs Again

Revenue collection is the biggest opportunity in the CFO stack, and Tabs is poised to own it. CEO and Co-Founder Ali Hussain is fierce in all the right ways: urgent and thoughtful, yet a true servant leader. Alongside co-founders Deepak Bapat and Rebecca Schwartz, and an extraordinary team of passionate builders, Tabs is creating one of the most promising vertical-AI companies in New York City.

Today, we’re excited to announce our continued support of Tabs, the AI-native revenue platform for modern finance teams, as a part of its $55 million Series B led by Lightspeed Venture Partners. Tabs is automating the revenue engine for the AI-Native CFO, powering fast growing companies like Cursor, Statsig, and Cortex.

Accounts receivable, the all-important task of collecting revenue, is breaking free from the ERP. There are incredible decacorns associated with every layer of the CFO stack—Ramp for spend, Rippling for payroll, Bill.com for AP—but no company owns AR. The ERP is unbundling as enterprises are modernizing, with 50% of CIOs expecting to upgrade their ERP in the next two years. The ERP historically dominated the CFO stack, but lengthy implementations, expensive pricing, brittle architecture, and antiquated product experiences created an opening to build best-in-breed solutions for each category.

We believe revenue is the biggest prize in this unbundling. Revenue collection sees the biggest flow of money. It commands the most time from experienced, senior members of your team. Given the complexity and criticality of revenue, the market opportunity for Tabs swells to over $1 trillion given in senior labor spend required to manage revenue and billing operations at companies of all sizes.

Tabs transforms AR from a manual, ops-heavy burden into an automated revenue engine. By making contracts—not CRMs or spreadsheets—the system of record, Tabs enables CFOs to say “yes” to growth, experimentation, and new monetization models without getting trapped in their legacy ERP.

The Finance Stack Wasn’t Built for the AI Era

Accounts receivable has historically been a burden finance teams haven’t been able to engineer themselves away from. Legacy approaches to AR force companies to map CRM and billing data through tools like NetSuite or Stripe, creating endless edge cases. Contractual deviations—discounts, custom usage, multi-year contracts—becomes a painful manual exercise, ballooning the size of finance ops teams. It could take three days to reconcile contracts in an Excel doc with what’s in your CRM, manually cross-reference materials, feed that data back into your ERP, then automate a billing flow. The painful result is delayed collection of revenue.

AI has created an incredible opportunity to transform AR, improving accuracy on contract parsing, reducing time spent on reconciliation, and making the platform flexible to new pricing models. AI is the unlock that enables Tabs to convert a contract into cash. By treating the contract—the same artifact auditors already rely on—as the source of truth, Tabs eliminates manual reconciliation, using AI to collect unstructured contracts and automatically turn it into revenue.

Pricing innovation makes this shift even more urgent. AI-native companies are experimenting with consumption billing, usage-based pricing, and hybrid models at a pace legacy systems can’t support. Even if you solved the data mapping problem, introducing a new pricing model renders it useless in moments. Traditionally, this made the CFO the brake on sales creativity, prioritizing revenue clarity over pricing innovation. Tabs changes that: finance becomes a team of “yes,” with revenue systems that adapt as quickly as sales. For CFOs navigating the AI era, this flexibility is crucial to keeping up, as every company knows its pricing will evolve, and AR must keep pace.

The result with Tabs is faster closes, leaner teams, and higher confidence for both finance and auditors.

Contract-to-cash and beyond

Tabs is built for this moment. Its wedge is contract-to-cash automation: ingesting messy contracts, extracting commercial terms, generating invoices, chasing payments, and recognizing revenue with minimal human involvement. Tabs’ ingestion engine transforms static PDFs into bill-ready logic, while Slack-native workflows and API-first integrations embed directly into how finance teams already operate. Tabs isn’t just digitizing invoicing—it’s reimagining the entire revenue cycle.

Billing and revenue often require senior team members tackling mundane tasks. Their work also exists across many solutions, referencing the contracts, CRM, ERP, payments processor, and other systems to recognize revenue. This cross-functional workflow that requires domain expertise makes it perfect for agentic automation, freeing up teams to do higher value work. Tabs makes it possible to automate everything from edge cases and revenue rules that used to require armies of finance professionals.

CEO Ali and the Tabs team believe the future of finance looks like this: lean senior teams powered by swarms of AI agents managing revenue at scale. From your first dollar to your billionth, the platform automates billing, collections, revenue recognition, audit, and reporting – with an auditable trail across the CFO stack.

That vision unlocks more than AR. With the launch of Tabs Agent, its Slack-native AR agent, Tabs is taking the first step toward building a true agentic revenue platform.
