Singlefile

SingleFile is a cloud-native compliance filing automation platform that handles annual reports, state filings, entity formations, foreign qualifications, registered agent services, and Corporate Transparency Act (CTA) beneficial ownership reporting. Founded 2019 in Seattle (now fully remote), $24M+ total funding including a $9M Series A (Feb 2025) led by Foundry Group with Pioneer Square Labs and The LegalTech Fund. Strategic investors include Wilson Sonsini, Cooley, DLA Piper, Fenwick & West, Perkins Coie, and individual attorneys from K&L Gates. 60+ law firm clients including 33 Am Law 200 firms. 4,000+ total customers. ~49 employees. CEO Aaron Finn positions SingleFile as ‘the Stripe of corporate compliance’ — automating the manual, paper-intensive filing processes that CT Corporation (Wolters Kluwer) and CSC Global have dominated for decades. Key differentiator: service-based pricing (pay per filing) with no platform fees, no per-entity fees, and no seat fees — roughly 50-60% cheaper than traditional providers per vendor claims. SingleFile explicitly distinguishes itself from entity management/governance platforms like Athennian or Diligent — it’s filing automation, not a full entity register. Half of revenue comes from law firms (corporate paralegals filing for clients), half from corporate legal departments directly. PE/VC, private wealth, and real estate firms are additional user segments. CTA compliance module launched 2024 and drove strongest growth (Nov-Dec 2024 saw 3x YoY law firm usage). Listed in Stanford CodeX TechIndex (compliance, risk management). No G2 or Capterra reviews found. No Reddit discussion found. No SOC 2, SSO/SAML, or security architecture documentation publicly available — a notable gap for a platform handling sensitive BOI data (SSNs, passport numbers). Keyword ‘singlefile’ is conflated with the SingleFile browser extension (Firefox/Chrome) and SingleFile Wines (Australian winery) — actual SingleFile Technologies search volume is near zero.
