Sim Raises $7 Million Series A to Power Visual, Open-Source AI Agent Workflows
Sim, a San Francisco–based artificial intelligence infrastructure startup, has raised $7 million in a Series A funding round, marking a significant milestone in the company’s growth as demand accelerates for tools that simplify the creation and deployment of AI-powered workflows. The funding underscores growing investor confidence in Sim’s visual, open-source approach to building agent-based systems that bridge the gap between no-code tools and complex engineering frameworks.
The Series A round was led by Standard Capital, an early-stage venture firm that backs companies building foundational technology platforms. Additional participation came from Perplexity Fund, which focuses on frontier AI investments, SV Angel, a long-standing supporter of early-stage technology startups, and Y Combinator, the startup accelerator that included Sim in its Spring 2025 cohort. The round also included backing from well-known angel investors from the technology ecosystem, reflecting broad confidence in the company’s long-term vision.
Founded in 2025 by Emir Karabeg and Waleed Latif, Sim was built around the idea that developing AI systems should not require choosing between rigid visual tools and highly technical code-first solutions. The company’s platform offers a visual canvas that allows users to design, connect, and deploy AI agents and workflows through a drag-and-drop interface. This design enables developers and teams to move more quickly from experimentation to production while maintaining flexibility and control over system behavior.
Sim’s platform is centered on agentic workflows, which allow multiple AI components to reason, retrieve data, and act together to complete complex tasks. These workflows can integrate with a wide range of tools and services, making the platform adaptable across use cases such as automation, research, internal operations, and customer-facing applications. By offering both an open-source core and a managed cloud version, Sim caters to individual developers as well as organizations seeking scalable infrastructure.
The company has seen rapid adoption since launch, driven in large part by its open-source strategy. Sim has attracted a large and active developer community, earning tens of thousands of stars on GitHub and engagement from tens of thousands of developers worldwide. More than 100 companies are already using the platform in live environments, according to the company, highlighting its traction beyond experimentation and into real-world production use cases.
Sim’s popularity is also fueled by its growing ecosystem of integrations. The platform supports connections to popular productivity and collaboration tools such as Google Drive, Slack, and Gmail, as well as local and cloud-based model execution options. This flexibility allows users to design workflows that fit seamlessly into existing technology stacks, reducing friction for adoption and deployment.
With the new funding, Sim plans to accelerate product development and expand its engineering team. The company intends to enhance its core platform capabilities, improve performance and reliability, and introduce additional tools aimed at enterprise users exploring agent-based automation. A portion of the capital will also be allocated to supporting and expanding the developer community through improved documentation, educational resources, and community-driven initiatives.
Investors backing the round see Sim as well positioned within a rapidly evolving AI tooling landscape. As organizations increasingly rely on autonomous agents to handle tasks such as data analysis, customer support, and internal operations, the need for intuitive yet powerful workflow-building platforms continues to grow. Sim’s visual-first approach aims to lower the barrier to building complex AI systems without sacrificing extensibility or control.
Looking ahead, Sim’s leadership envisions a future in which software is increasingly composed of interconnected intelligent agents. By providing a flexible, visual foundation for designing and deploying these systems, Sim aims to become a core layer in the emerging agentic AI ecosystem. With fresh capital and strong early traction, the company is positioned to deepen its footprint in the AI infrastructure market and scale alongside the growing adoption of autonomous AI workflows.
