Launch YC: Dari - The easiest way to build reliable browser use agents

"Easily and reliably automate any web workflow, even when it's blocked by 2FA."

TL;DR: They have built the first browser automation platform reliable enough for production. While other agents fail on repetitive tasks, Dari caches successful workflows and handles 2FA automatically, making browser automation actually work for real businesses.

Founded by Avyay Varadarajan & Benjamin Hong

Two Caltech CS grads who have previously worked on software at Amazon and Uber.

They have been building with browser use agents since the initial model releases and were constantly frustrated by how unreliable they were for production use-cases. They built Dari to fix the problems they have noticed since the start.

The Problem / ✅ Their Value

Running regular browser use agents as-is has limited viability for repetitive tasks. They're too slow, too expensive, and too unreliable. And forget about authenticated sites: most agents can't handle 2FA at all.

Dari is different. They are purpose-built for production use, combining intelligent caching with automatic 2FA handling so your automations actually run reliably, day after day.

💪 Their 3 Core Strengths

1. 🔒 2FA That Actually Works: Automate Authenticated Workflows

  • Universal 2FA support: Automatically handles text message codes, TOTP authenticators, and email verification.

2. ⚡ Intelligent Caching: Fast and Reliable

  • Run once, cache forever: After running a workflow with an LLM once, Dari can replay the workflow using deterministic DOM steps
  • Fallback intelligence: If a site changes, Dari automatically detects it, adapts, then caches the new path
  • Why other agents fail: Regular browser-use agents call LLMs on every single run. Dari only uses AI when needed.

3. 🧩 Built for Developers: Real Integration, Not Toys

  • Chat-to-automation: Describe your workflow in plain English and get a working automation in seconds.
  • API-first triggers: Start workflows via POST request, integrate directly into your stack.
  • Webhook & Wait: Call your backend mid-workflow, run custom code, and continue the automation seamlessly.

💥 Real Impact

  • A voice AI company automated data entry and form filling tasks, saving 10+ hours per week.
