Activeloop, a Y Combinator (YC18) company founded in 2018, builds Deep Lake, an open-source database for AI. Deep Lake lets teams index, search, organise and reason over large multimodal datasets - documents, images, video, LiDAR and telemetry - using natural language and LLM-powered workflows. A Postgres-compatible layer unifies multimodal streams and makes them streamable to GPU training pipelines. The technical domains behind the product span multimodal AI, vector search, Retrieval Augmented Generation, high-dimensional and time-series data, computer vision and natural-language search.
The project has attracted 9k GitHub stars and 5m downloads, with a Slack community of more than 3,200 members. Enterprise deployments include Fortune 500 organisations such as Bayer Radiology; published case studies report an 18% improvement in retrieval accuracy at Flagship Pioneering and an 18.5% productivity gain for lawyers at Hercules.ai and Ropers Majeski. Verticals served include healthcare and radiology, biotech, legal, and AI/ML research. The company has raised just shy of $20m in total, including an $11m Series A, and works with Intel (Intel Disruptor Program) and AWS (AWS Partner Network, AWS Marketplace) as go-to-market partners.
Activeloop works onsite from hubs in California and Yerevan, Armenia, alongside global enterprise deployments. The team describes itself as fast-moving, shipping quickly and taking ownership, and builds in the open with its community. Hiring runs through structured interviews assessed on objective criteria, with salary ranges published on every role and feedback provided to candidates on request.
Benefits include medical, vision, dental and life/AD&D insurance, a 401(k) plan, meaningful equity for all employees, and annual compensation reviews. Growth is supported through mentorship, learning resources and ownership of real work. The company is an Equal Opportunity Employer.
