San Francisco startup Sim is scaling an open-source visual platform designed to build, deploy, and monitor autonomous AI agents across enterprise systems. Founded in 2025 out of Y Combinator, the five-person team raised a Series A led by Standard Capital, with backing from Perplexity, SV Angel, Liquid 2 Ventures, and TwentyTwo VC.
The company has paired its open-source repository—which gathered 26,000 stars over its first eight months—with a cloud service that has registered more than 60,000 developers. To manage growing production workloads across enterprise clients and public sector deployments, Sim is hiring for six onsite roles in San Francisco across engineering, product design, and go-to-market teams.
Visual Orchestration for Enterprise Workflows
Sim builds a visual orchestration canvas that combines drag-and-drop components with natural language workflow generation. Instead of configuring agents through deep code abstractions or rigid rule engines, users arrange modular blocks connected to model providers, external functions, and integrations such as Supabase and Slack.
The platform integrates with enterprise environments by generating a knowledge graph across company databases and processes. Teams deploy these agentic workflows into production as streaming APIs that feature native guardrails, memory layers, and local model execution options.
In a video interview on YC Root Access, the founders explained that traditional workflow software missed the needs of AI-native execution, such as orchestrating an agent to repeat a subtask dozens of times or modifying system prompts in natural language. In an interview with Standard Capital, the team noted that enterprise users range from Y Combinator startups to the Department of Defense. One legal services company with $5 billion to $6 billion in revenue used the platform on premises to automate roughly half of the hours its employees spent triaging ambiguity in thousands of daily client emails.
The Founders
Sim was founded by UC Berkeley classmates Emir Karabeg and Waleed Latif.
Chief Executive Officer Emir Karabeg studied Data Science and Cognitive Science at UC Berkeley, where he conducted natural language processing research for machine translation. Before founding Sim, Karabeg launched WorkNinja, an early chain-of-thought writing application that reached more than 300,000 monthly active users.
Chief Technology Officer Waleed Latif studied Computer Science and Cognitive Science at UC Berkeley, leading engineering and publications for Neurotechnology at Berkeley. Before Sim, Latif was an engineer at Amazon, where he built backend infrastructure for Ring that handled more than 1 million transactions per second.
The founders initially tested ideas in CRM software and dynamic websites under a project called Scale Mount. Managing an internal codebase with hundreds of isolated agents prompted them to scrap the product and build a shared visual canvas for orchestrating models, memory, and tool calls.
Engineering the Core Harness and Interface
Sim ships code on a strict cadence, committing to public updates every two weeks. With enterprise adoption growing, the engineering team is expanding to solve reliability, context management, and interface performance.
The company is hiring a Software Engineer, Agent Harness ($200,000 to $250,000) in San Francisco. The role owns the underlying harness supporting context retrieval, multi-step planning, task execution, and memory. The work involves building evaluation frameworks and studying production execution traces to improve agent reliability against company knowledge bases.
To bridge technical depth with workflow usability, the team is bringing on a Founding Design Engineer ($200,000 to $250,000). This engineer will define interaction models for the canvas and co-pilot, structuring component architecture and application state so non-technical and technical operators can design complex multi-agent systems intuitively.
Sim is also hiring a Forward Deployed Engineer ($140,000 to $160,000). This hire works directly with customer teams on site, integrating company systems, constructing production agents, and creating continuous deployment pipelines.
Establishing Enterprise Sales Operations
While developer acquisition has relied on GitHub trending visibility and open-source contributions, commercial enterprise demand requires establishing formal sales processes. Sim is staffing three complementary commercial roles at its San Francisco headquarters.
The team is seeking a Founding Sales lead ($100,000 to $110,000) to build out a repeatable pipeline. The role covers the full sales cycle for enterprise accounts, from initial use-case discovery and technical demonstrations through contract negotiations.
To target large enterprise accounts, Sim is hiring a Founding Account Executive ($150,000 to $175,000). Working directly with Karabeg and Latif, this hire will convert inbound interest from Fortune 500 prospects into structured pilot programs, technical evaluations, and enterprise licensing contracts.
Sim is also hiring for Founding GTM ($120,000 to $160,000). Operating across marketing and customer implementation, this role involves interviewing users, building product demonstrations, authoring launch materials, and conducting outbound adoption campaigns.
