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’ (2,400/mo) is conflated with SingleFile browser extension (Firefox/Chrome) and SingleFile Wines (Australian winery) — actual SingleFile Technologies search volume is near zero.

Workflows
Based on practitioner evidence, Singlefile is used in these workflows:
What practitioners struggle with
Real frustrations from legal professionals — the problems Singlefile addresses (or should address). Sourced from practitioner reviews, Reddit threads, and case studies.
Company gets a letter saying beneficial ownership reports are due under the Corporate Transparency Act — they have 40 LLCs across 8 states, each with different beneficial owners, and nobody has a centralized record of who owns what percentage or their current addresses, so the compliance officer is scrambling to collect SSNs and passport copies from dozens of individuals before the deadline
Law firm handles entity formations and foreign qualifications for clients expanding into new states — each state has different forms, fees, name availability rules, and processing times, and one missed foreign qualification means the client can't legally operate in that state and the deal stalls
Where it fits in your workflow
Before Singlefile
Client forms a new entity or expands to new states → needs annual report filings, foreign qualifications, registered agent services, and CTA/BOI reporting. Traditionally handled by CT Corporation or CSC Global (paper-intensive, per-entity pricing) or manually tracked in spreadsheets by corporate paralegals.
After Singlefile
After SingleFile handles filing → entity is in good standing → deal can close, business can operate in new jurisdiction. CTA/BOI reports filed with FinCEN. Law firm bills client for compliance services. Entity data feeds into broader entity management systems (Athennian, Diligent) or internal registers.
Integrations & hand-offs
SingleFile (filing automation) → Secretary of State offices (actual filings) → FinCEN (CTA/BOI reports). No documented API or integration with practice management systems, DMS (iManage/NetDocuments), or entity governance platforms. Client-facing data collection for BOI (beneficial owners enter own info).
