LA battery AI using reinforcement learning for grid-scale BESS optimization with CAISO certification; YC $3M seed from Rivian battery data science team competing with Stem for intelligent energy storage dispatch.
Keeling Labs is a Los Angeles-based battery AI company — backed by Y Combinator with $3 million in seed funding from YC, GMO Venture Partners, FoundersX Ventures, and Climate Capital — developing reinforcement learning platforms for grid-scale battery energy storage system (BESS) optimization, enabling operators of large battery installations to maximize revenue from energy arbitrage, frequency regulation, and capacity markets through AI that continuously learns optimal dispatch strategies. Founded in 2022 by Jack O'Grady with a team from Rivian's battery data science group, Keeling Labs achieved California CAISO regulatory certification in fall 2023 and deployed its ML model to actively trade energy in California markets in 2024.
Digital construction safety management platform for contractors enabling mobile safety inspections, incident reporting, and compliance documentation; replaces paper forms to create auditable records and reduce regulatory and legal exposure.
BuildSafe is a Stockholm-based construction safety management platform that digitizes safety inspections, incident reporting, risk assessments, and compliance documentation for construction contractors and project owners. The company was founded on the observation that construction remains one of the most injury-prone industries globally, yet safety management processes at many construction firms still rely on paper forms, spreadsheets, and email—creating documentation gaps that expose workers to risk and companies to regulatory and legal liability. BuildSafe provides a mobile-first platform that enables foremen and safety managers to conduct digital safety rounds, log near-misses and incidents, manage action items, and generate audit-ready safety reports from the job site.\n\nBuildSafe's inspection and observation workflows are configurable to the specific risk profiles of different construction activities—scaffolding, heavy lifting, excavation, electrical work, and confined space entry each carry distinct hazard profiles requiring tailored checklists. The platform allows safety managers to create custom inspection templates aligned with national safety regulations and company-specific standards, and tracks completion rates and outstanding corrective actions across multiple job sites simultaneously. When a hazardous condition is observed or an incident occurs, BuildSafe routes the report to the appropriate responsible party with automated follow-up reminders until the corrective action is documented as resolved.\n\nBuildSafe operates primarily in the European market, where construction safety regulation is increasingly stringent under EU directives and national frameworks, and has particular strength in the Nordic countries where construction digitalization has advanced rapidly. The company targets mid-market and large general contractors, infrastructure developers, and public sector project owners. BuildSafe competes with Assignar, Salus Technologies, and Procore's safety module in the construction safety management software segment, differentiating on its European regulatory alignment and its mobile-first design for field-based safety teams.
