Founded in 2022, Fractile develops chips and systems aimed at dramatically speeding up inference for frontier AI models. The company’s thesis is that time-to-output and inference unit economics—particularly memory bandwidth limits—are the next major bottlenecks as models generate increasingly long outputs. Fractile is working across AI research, chip microarchitecture, and foundry process innovation to reduce inference latency and cost. Its technology targets workloads that can require tens of millions of tokens and seeks to enable new, longer-running AI tasks by making faster inference economically viable. The company is expanding its team and hiring across London, Bristol, San Francisco, and Taipei as it scales development. Financial metrics, customers, and prior funding amounts were not disclosed in the articles.

Vsim is building a physics simulation framework designed to enable high-performance, real-time simulation for robots operating in dynamic, unpredictable environments. The company has been largely stealthy to date and maintains a sparse public presence. Its initial go-to-market focus is robotics training, though Vsim’s founders and investors see potential applications across research, entertainment, manufacturing, and pharma. Vsim emphasizes simulation that can act with speed and accuracy while taking real-world variability (rooms and environments) into account. The company was founded by Michelle Lu and Kier Storey, who spent over a decade building simulation technology at Nvidia after earlier work in games and physics. Vsim has raised significant seed capital and is reported to be valued at around $100 million.

Founded in 2022, Perplexity provides an artificial-intelligence search and answering platform that pulls content from verified sources to give concise, citation-backed responses. The product is positioned as a next-generation alternative to traditional search engines, allowing users to ask open-ended questions and receive conversational, source-linked answers. To deepen user engagement, the company releases curated experiences such as the newly launched Cristiano Ronaldo hub, which lets fans explore never-before-seen images, interactive pitch visualizations of goals, and detailed career statistics. This strategy highlights Perplexity’s aim to blend authoritative data retrieval with immersive, vertical-specific content. Ronaldo’s endorsement is expected to boost the platform’s global visibility, particularly among sports enthusiasts. While no revenue or user figures were disclosed in the article, the partnership signals Perplexity’s plan to attract high-profile collaborators and embed its AI tools in mainstream culture.
