About
Tabs is a New York City-based legal AI company that builds contract intelligence and billing management tools specifically for law firms, enabling practices to automatically extract and track financial obligations, billing milestones, rate escalations, and payment terms from engagement letters and client contracts. Founded in 2022 and having raised more than $7 million, Tabs addresses a specific operational pain point: the difficulty law firms face in manually tracking contract terms across hundreds of client agreements and ensuring that billing aligns with negotiated engagement terms.\n\nTabs's AI platform ingests engagement letters, fee agreements, and client contracts and extracts structured data including billing rates, rate escalation schedules, matter-specific billing guidelines, advance payment terms, and milestone payments. This extracted data flows into the firm's billing workflow, where it serves as an automated check on invoices and a proactive reminder for billing triggers that would otherwise be missed. The platform integrates with practice management systems to connect contract intelligence directly to matter billing operations.\n\nThe company targets a specific and underserved problem in law firm operations — the gap between what was agreed to in engagement letters and what gets billed — that costs law firms revenue and creates compliance risk with clients. Tabs competes with general-purpose contract management tools and CLM platforms but differentiates through its focus on the billing and financial terms extraction use case specific to law firm-client relationships. The company's early traction among AmLaw 200 firms and boutique practices reflects genuine demand for its focused AI application.
