Top Artificial Intelligence Startups in San Francisco, CA

Idler builds reinforcement learning environments that teach AI models to code like 0.01% engineers. Our training environments are based on real-world coding scenarios that frontier models will actually encounter.

DeepSigns is revolutionizing document processing in the construction industry through advanced AI. We're currently in stealth working with a design partner in solving a critical industry pain point: the time-consuming, error-prone process of extracting meaningful data from contracts, bonds, and financial statements. Our AI-powered platform offers: - Intelligent document processing: Converting complex construction documents into structured, actionable data - Automated data extraction: Transforming unstructured documents into organized, searchable information - Smart document analysis: Quickly processing and standardizing varied document types across construction workflows Initial results: - 95% reduction in document processing time - Potential for millions in cost savings for construction firms - An estimated 1.5 million labor hours saved if our technology was applied across our design partner's industry We're creating a new standard for document processing in construction, moving outside of our current design partner's niche sector to the entire construction ecosystem. Our market is massive and underserved. The U.S. construction industry alone is worth over $1.3 trillion, with billions spent annually on document processing and management. We're well positioned to go after this market. DeepSigns isn't just another AI-wrapper startup. We're tackling real-world problems with solutions that can reshape an entire industry, and our solutions only get better with better frontier models. No worries of being 'steamrolled' here as the models improve. Our goal: become the obvious choice for construction document processing, saving clients time, money, and headaches. Join us in bringing clarity to construction's complex documentation.

We partner with healthcare institutions to build AI-powered workflows on a unified data foundation. Our mission is to make the best healthcare possible available to every human on the planet.

Callab AI builds AI voice and text agents for enterprise contact centers. We help companies automate customer conversations while keeping the telephony, CRM systems, and workflows they already rely on. Many contact centers run on established on-premises phone systems. Bringing AI to those environments is an infrastructure challenge as much as a modeling challenge. Our SIP-native telephony stack connects directly to systems such as Cisco CUCM, Avaya, and Mitel, so customers can deploy AI agents without replacing their phone infrastructure. Our platform lets teams build agents around their knowledge and business rules, connect them to tools that complete customer tasks, and supervise conversations in real time. When a conversation needs human judgment, a team member can take over with the context preserved. Use cases include customer support, call routing, appointment scheduling, lead qualification, and outbound campaigns. Backed by Y Combinator, We serve customers across three continents and are expanding in the US. Our work spans enterprise software, AI, and the telecom infrastructure that makes reliable customer service possible. We're building the next generation of contact-center automation. Explore our open roles to help bring it to more businesses.
