Daytona Platforms Series B Funding Raises $60 Million at $1 Billion Valuation

Daytona Platforms completed a $60 million Series B funding round around October 20, 2026, at a $1 billion post-money valuation. FirstMark Growth led the round, which brought total capital raised to roughly $91 million since the San Francisco-based company's founding in 2023.

Funding Details and Investors

The round included approximately $50 million from existing backers. FirstMark Growth had previously led the company's $24 million Series A in February 2026. Other participants included angel investors Patrick Collison of Stripe, Tobi Lütke of Shopify, Aravind Srinivas of Perplexity, Eric Yuan of Zoom, Olivier Pomel of Datadog, Adam D’Angelo of Quora and OpenAI's board, and Brendan Foody of Mercor. Strategic investors Qualcomm Ventures, Samsung Next, Okta Ventures, Alumni Ventures, Evergreen Fund, and Torch Capital joined the round along with prior supporters Upfront Ventures, Pace Capital, and E2VC.

Proceeds will support expansion of the platform beyond core sandboxes, addition of browsers and storage features, scaling of compute infrastructure, and hiring across offices in San Francisco, Croatia, and Singapore. The company reported a revenue run rate that increased roughly 25 times between January and September 2026, with average monthly net revenue retention near 135 percent after its pivot to agent-focused infrastructure.

Platform Capabilities and Customer Base

Daytona operates an agentic cloud that supplies secure, isolated sandboxes for AI agents. The infrastructure supports Linux, Windows, macOS, and GPU environments with startup times of 60 to 90 milliseconds through pre-loaded snapshots. Features include persistent state, forking and cloning of instances, pausing and resuming workloads, and safe execution of tools such as Git and browsers. The system functions as an execution layer separate from model inference or observability platforms.

Customers include Anthropic, OpenAI, Nvidia, Meta, Cohere, Cursor, Cognition, Snorkel, Writer, Clay, and n8n. More than one million sandboxes have been provisioned to date for model development, data training, and production agent deployments. CEO Ivan Burazin and co-founders Goran Draganić and Vedran Jukić noted that agents require different primitives than traditional long-lived cloud services, prompting the company's shift from human developer environments to this agent-native focus after a relaunch around April 2025.

Growth Trajectory and Expansion Plans

The three-year-old startup has positioned its offering for rapid agent adoption across model labs and enterprise teams. Growth metrics reflect strong demand following the pivot, with continued platform development planned to meet production-scale requirements. No additional funding rounds or exact timelines for new features were disclosed in the announcement materials.

Existing customers already use the sandboxes for both research workloads and live agent operations. The company intends to broaden its compute footprint and engineering resources while maintaining security isolation standards that differentiate the service in the emerging agent infrastructure market.
