Modular raises $380M from top VCs to challenge Nvidia's AI dominance with new software stack

Modular, a startup co-founded by Apple and Google software veterans Chris Lattner and Tim Davis, has raised $380 million from investors including Greylock, General Catalyst and GV, reaching a valuation of $1.6 billion in its latest September funding round. The company is challenging Nvidia's CUDA software platform, which has dominated AI development for nearly 20 years by binding workloads to Nvidia GPUs. Lattner, known for creating Apple's Swift programming language, and Davis previously built software for Google's TPU AI chips. Modular has developed a new AI software stack including Mojo, a programming language designed to work across different chip manufacturers whilst maintaining Python-like usability. The company recently announced achieving top-level performance on both Nvidia's Blackwell B200 and AMD's MI355X GPUs using the same software platform, with AMD chips showing approximately 50% better performance than when using AMD's own software.

And it says something about how branding, trust, and long-term ambition play a bigger role in how startups choose to present themselves.Why Startups Went With .AI DomainsIn the early days, .ai domains were easy to get and made a lot of sense.
