Billables AI, a three-year-old company that promises to help lawyers capture more of the hours they work—and actually bill for them—closed a $10.2 million Series A round on June 9. Avenue Growth Partners led the financing, with Wing VC, SignalFire, and Alumni Ventures joining in.
The announcement comes barely three months after the San Francisco startup collected something of a validation prize: "Legal Tech Company of the Year" at the Legalweek Leaders in Tech Law Awards in March 2026. For a company founded in 2023, that's the kind of early momentum that tends to get the attention of growth investors—particularly in a sector where the gap between hours worked and hours billed remains a stubborn, expensive problem for law firms.
The pitch is simple, if not exactly poetic. Billables AI automates time capture. The platform connects to Microsoft 365, Google Workspace, Zoom, Adobe, and a handful of other productivity tools via API, quietly tracking work activity in the background and matching it to clients and matters. Then it generates narrative time entries—no screenshots, no invasive monitoring, just a running log of what lawyers are doing and for whom.
It's the sort of thing that sounds almost too mundane to attract venture capital, until you consider the economics. Law firms, especially midmarket practices where Billables has focused much of its effort, routinely lose revenue to what the industry euphemistically calls "leakage"—unbilled hours that slip through the cracks because someone forgot to log them, or couldn't quite remember what they were doing at 3 p.m. on a Thursday two weeks ago.
The company says it now works with hundreds of law firms. It integrates with major practice management systems: Clio Manage, MyCase, Centerbase, SurePoint, LeanLaw. In May, Litify went a step further, embedding Billables' technology as "LitifyAI Time Capture" directly into its own platform.
Client testimonials posted on the company's website claim gains ranging from 10% to 30% more billable time captured. Blair Zigler, CEO of Zigler Law Group, said the firm "captured 30% more billable time." Brian Belt, founding partner at Acevedo Belt, stated his firm "recouped annual investment in 2 days." Whether those results hold across the broader customer base—or represent outliers—remains unclear.
Following the Money
The Series A brings Billables AI's total disclosed funding to roughly $14.1 million. Wing VC, which led the company's $3.9 million seed round in October 2024, returned for this round. F7 Ventures, Darkmode Ventures, and a handful of angel investors also participated in the earlier financing.
Avenue Growth Partners, an early-stage growth equity firm that concentrates on vertical software, most recently led Boom's $12.7 million Series A in November 2025. Partner Brian Goldsmith noted the investment in the June 9 announcement, though the firm declined to disclose valuation—a common practice in a market where startups have grown cautious about publicizing numbers that might not age well.
The company plans to deploy the proceeds in predictable ways: product R&D, expanded go-to-market efforts, deeper ecosystem partnerships. More interestingly, perhaps, Billables is pushing beyond simple time capture into what it calls "operational intelligence"—productivity insights, revenue forecasting, and tracking AI application usage for risk and governance purposes. That last piece reflects a growing concern among law firms as generative AI tools proliferate: how do you know what your lawyers are actually using, and whether it's creating liability?
The Team and the Competition
Co-founder and CEO Arvind Sujeeth holds a Stanford PhD and previously worked at SambaNova Systems and as co-founder and CTO of mines.io. Nancy Jeng, who led product marketing at Pinterest before co-founding Billables, rounds out the founding team. Last July, the company added John Ing, previously at Clio, and Alexis Hayman, formerly of Consilio and Everlaw, to lead sales and customer success.
The legal timekeeping automation space has drawn steady, if not exactly frenzied, investor interest. Competitor PointOne raised $16 million in a Series A in March 2026—the same month Billables won its award. Laurel (formerly Time by Ping) closed a $100 million Series C in June 2025, a far larger round that signaled investor appetite for the category. Established players like BigHand and WiseTime continue to invest in AI-powered time capture features, while newer entrants including LawGro, Inlet, and TimeSentry keep arriving.
It's a crowded field, which raises the usual questions. Can Billables AI differentiate itself beyond integrations and ease of use? Will law firms, notoriously slow adopters of new technology, actually change their behavior at scale? And perhaps more pressingly: how much of this market can sustain venture-backed growth expectations?
For now, at least, the bet is that there's enough inefficiency left in legal billing to support a handful of well-funded competitors. Whether that proves true may depend less on the technology itself than on whether law firms decide that capturing every billable hour is worth the cultural shift required to get there.
