Lazarus AI has raised $43 million to expand AI that enterprises and governments can control. Investors include QBE, Mucker Capital, Motivate Ventures, State Farm Ventures, Techstars, and Plug and Play. The Boston company lets customers keep control of their data, models, deployment, and costs. Its platform runs on-premises, in sovereign environments, or in a customer's cloud, with no per-token charges. Its products cover document analysis, cybersecurity, and legacy code modernisation. In a modelled high-volume scenario, the platform cut annual operating costs 78% versus pay-per-use frontier models. Lazarus will use the funds to expand partnerships, invest in R&D, and launch new products.
