AI Startups Command High Valuations

The top 10 companies in this ranking are all linked to artificial intelligence in some shape or form.

Thinking Machines Lab is a San Francisco-based AI startup founded by Mira Murati (former CTO of OpenAI) that aims to build more understandable, customizable AI systems. Its first product is called Tinker, a Python-based API for fine-tuning large language models (LLMs).

Tinker brings frontier tools to researchers, offering clean abstractions for writing experiments and training pipelines while handling distributed training complexity. It enables novel research, custom models, and solid baselines. Mira Murati, CEO of Thinking Machines Lab

Further down the list is Decart, which is developing real-time generative AI capabilities which can be used for gaming, media, and streaming. The company also offers an infrastructure platform that reduces compute costs for training AI models.

Rounding out the top 10 list is Lovable, a Swedish AI startup worth nearly $2 billion. The firm is one of Sweden’s fastest growing startups, offering a “vibe-coding” platform that allows users to build full-stack apps from simple, natural-language prompts.
