Corto

What Corto does

Corto Pty Ltd is an Australian-headquartered, privately held software company that builds an AI-powered legal technology platform for law firms. The company operates from Sydney with a development team in San Francisco and product/sales presence on the US East Coast, and serves customers across Australia, the United States, Canada, the United Kingdom, and New Zealand. Founded in 2023 with a team described as having 25 years of combined legal-tech experience, Corto positions itself as a purpose-built AI workflow layer for lawyers rather than a general-purpose AI tool.

The core product, branded CORTO, is a cloud-based SaaS platform hosted on Amazon Web Services infrastructure (us-west-2) that uses OpenAI's generative models for AI capabilities. The platform is composed of multiple modules: CORTO Chat for matter-scoped conversational AI and document Q&A, CORTO Prompt Library for templated legal document generation filtered by jurisdiction and matter type, CORTO AI Form Filler for automated completion of fillable PDF and Word forms, a Facts management system with relevancy scoring, Canvas Control for section-level editing of AI outputs, a Contacts Management module, and a CORTO AI for Word add-in distributed via Microsoft AppSource. It also integrates with LawY for advanced legal research and with OneDrive, Dropbox, Google Drive, and Outlook for document storage, matter management, and email automation. The platform holds SOC 2 Type II, CASA Tier 3, and EU-US Data Privacy Framework certifications, and Corto states that client data is never used to train AI models.

Corto monetizes through enterprise SaaS subscriptions billed annually, with pricing disclosed only via consultation rather than published rate cards. Go-to-market is enterprise field sales targeting law firms through a "Book a consultation" funnel on its website, supplemented by content marketing (help center, blog) and organic social. The customer base is concentrated in a single vertical (law firms) with the company claiming adoption across "thousands of law firms worldwide," though no individual customer logos, revenue figures, or funding rounds are publicly disclosed. Leadership includes founder and CEO Mark Burgess, CTO Robert Segner, and Head of Product Leslie Moczulski.

Direct peers

• iManage: iManage is a leading document and email management platform purpose-built for legal, overlapping directly with CORTO's matter-centric document workflow and integration footprint.
• NetDocuments: NetDocuments is the dominant cloud document-management system for law firms and competes directly with CORTO's document/matter storage layer and integrations with OneDrive, Dropbox, and Google Drive.
• Harvey AI: Harvey AI is a venture-backed generative-AI platform purpose-built for elite law firms, offering domain-specialised legal chat, drafting, and research — the closest direct analogue to CORTO's product and target customer.
• Spellbook: Spellbook uses AI to draft and review contracts directly inside Microsoft Word for lawyers — overlapping strongly with CORTO AI for Word and the Prompt Library's contract-generation use case.

Emerging players

• Latch: Latch is an early-stage AI legal assistant focused on document and contract workflows for law firms — a smaller, emerging direct competitor in the same AI-for-lawyers niche as CORTO.
• EvenUp: EvenUp applies generative AI to personal-injury law firm workflows (demand letters, case valuation), representing a vertical-AI legal peer targeting a specific practice area with a similar technology stack.

Others

• Ironclad: Ironclad is a contract lifecycle management platform with embedded AI for drafting and review — adjacent rather than direct competition, since it serves in-house legal teams rather than law firms, but it overlaps with CORTO's document-drafting use cases.

Broad incumbents

• Wolters Kluwer: Wolters Kluwer embeds AI features across its legal and compliance software suites (e.g., Kleos, TyMetrix), giving it a broad-installed-base distribution channel that overlaps with CORTO's matter-management and drafting surface.
• Thomson Reuters CoCounsel: Thomson Reuters bundles CoCounsel AI into Westlaw and Practical Law, giving incumbent law-firm customers an embedded AI option backed by proprietary legal content — the broadest competitive threat to standalone legal-AI vendors like CORTO.
• LexisNexis (Lexis+ AI / Protégé): LexisNexis integrates generative AI (Protégé, Lexis+ AI) directly into its case-law and research platform used by most large law firms, competing head-on with CORTO's chat, research, and drafting workflows.
