Sim.ai has raised a $7 million Series A round led by Standard Capital, marking a significant step forward for the Y Combinator–backed startup as it scales its agentic AI platform. The latest financing round underscores growing investor confidence in the agentic-AI category. Alongside Standard Capital, the round drew participation from a group of influential backers, including Paul Graham, Perplexity, SV Angel, Ali Rowghani, Liquid 2 Ventures, Kulveer Taggar, Twenty Two Ventures, Kaz Nejatian, Chris Howard, Y Combinator, and additional supporters from the startup and AI ecosystem.
The company, a graduate of YC’s X25 batch, is building a foundation for competent autonomous AI agents designed to execute complex, multi-step tasks with minimal human guidance.
Founded to push AI systems beyond conversational interfaces, Sim.ai focuses on enabling agents that can reason, plan, take actions, and integrate deeply with business workflows. The platform is being developed to help organizations deploy AI agents that can operate software tools, manage processes, and complete end-to-end work across various domains, including research, operations, sales, and customer support.
Sim.ai has been gaining early traction among teams that want to automate knowledge work without relying on rigid rule-based automation. The company’s approach centers on building “simulation-driven intelligence,” allowing agents to learn through iterative trial, correction, and interaction with the environment, rather than relying solely on static training.
The new funding will enable Sim.ai to expand its engineering team, accelerate platform development, and support the company’s move into broader enterprise adoption as demand for autonomous AI agents continues to rise across industries.
