What Simular does

Simular builds autonomous AI agents that operate computers—browsers, desktops, and smartphones—the way humans do, by clicking, typing, and interacting with graphical user interfaces. The company's core product, Sai, is an always-on AI co-worker that runs on a private, isolated cloud-based virtual desktop and executes multi-step tasks end-to-end across applications, APIs, terminals, and code. Sai is delivered via the sai.work web product, the Simular Pro desktop application for macOS (v1.0 released December 2025, with a Windows version in development), and Simular Cloud for isolated execution. Underlying technology combines accessibility tree parsing with vision grounding to deliver reliable, deterministic UI automation that does not rely on brittle CSS selectors—a technique that has driven the company's open-source Agent S research series to #1 rankings on the WebVoyager (90.1%), OSWorld (72.6% super-human), and AndroidWorld (71.6%) benchmarks. The team is led by founders Li Ang (CEO), Jiachen Yang, and Xin Eric Wang, all with Google DeepMind backgrounds, and has been researching AI agents since 2017.

The commercial product lineup spans Simular Pro (individual subscription), Simular for Business (team/enterprise SKU), Simular Cloud (execution infrastructure), and Simulang, a TypeScript-based open-source scripting language distributed via npm and designed to be written with AI coding agents like Claude Code and Cursor. Simular employs a hybrid go-to-market motion combining product-led growth (direct downloads, invite-code-gated free tier, Product Hunt #1 Product of the Day launch, 9.9k GitHub stars, 1.9k Discord members) with enterprise distribution through the Microsoft Windows 365 for Agents pilot and Google Cloud AI Accelerator membership. Revenue is generated via recurring subscriptions, with the company actively exploring flat-fee billing alternatives to token-based pricing for cost predictability.

The company is privately held and venture-backed. It has raised approximately $27M in total disclosed funding across a September 2023 seed ($500K), a June 2024 round (~$5M), and a December 2025 Series A of $21.5M led by Felicis with participation from NVentures (NVIDIA's venture arm), South Park Commons, Basis Set Ventures, and Flying Fish Partners. Customers to date are predominantly individual professionals and SMBs (a named case study is Trevino's Auto Mart, plus a dedicated dental practice vertical solution), with the Microsoft partnership positioning the company for enterprise expansion. No revenue or ARR figures have been publicly disclosed.

Scale indicators8 records

Recent moves6 records

Expansion highlights7 records

Broad incumbents

• OpenAI: OpenAI ships Operator, a native computer-use agent integrated into ChatGPT, and is the dominant frontier-model lab whose models Simular may integrate with. Directly competes in the computer-use agent category and controls its own distribution.
• Anthropic: Anthropic developed Claude Computer Use, one of the first widely-available computer-use agent APIs. It is both a direct competitor in the agent capability space and an LLM backend provider for Simular — creating an unusual supplier-and-rival dynamic.
• UiPath: UiPath is the established enterprise RPA incumbent. As Simular moves upmarket into Simular for Business, it competes for the same budget pools — though UiPath's deterministic-script model is fundamentally different from Simular's autonomous-agent approach.
• Automation Anywhere: Automation Anywhere is a major enterprise RPA platform competing for the same process-automation budgets Simular targets with its business tier. Provides established enterprise distribution and trust.
• Google DeepMind: Google DeepMind develops Gemini's computer-use capabilities and is the alma mater of Simular's founders. Both push the frontier of computer-use agents, with Google having the distribution advantage via Workspace and Android.

Direct peers

• Manus AI: Manus is a high-profile autonomous AI agent startup explicitly cited by Simular in its blog as a comparable player ('the rise of Manus and the flood of agentic tools that followed'). Both target general-purpose autonomous computer use for end users.
• Adept AI: Adept builds foundation-model-powered agents that operate software on behalf of users across browsers and enterprise tools — a direct competitor to Simular's value proposition with comparable benchmark-driven positioning.
• MultiOn: MultiOn develops an AI agent that browses the web and executes multi-step tasks autonomously. Comparable target market (productivity-focused end users and SMBs) and similar agentic architecture.

Emerging players

• Reworkd AI: Reworkd builds open-source web-scraping and task-automation agents. Overlaps with Simular on open-source browser-automation agents, though with a narrower web-scrape focus.
• Robocorp: Robocorp offers a Python-based open-source RPA framework targeting developers building automation workflows. Overlaps with Simular's Simulang scripting approach and developer-led automation motion.
