Sinai.ai
Sinai.ai is an AI-native reading platform turning books into interactive, multimodal experiences through its trademarked aiBook format. Readers can converse with the text, generate study guides and quizzes, translate into dozens of languages, and switch between reading and listening - all on fully licensed publisher content. Founded in 2024 and headquartered in San Francisco, the company closed a $1.45M pre-seed round in April 2026.
Transit
Transit is a Montreal-based mobile app that turns the chaos of public transportation into a single, legible screen. It aggregates real-time schedules, GPS vehicle locations, and crowdsourced rider data across more than 1,100 cities in dozens of countries, layering in bikeshare, carshare, ridehail, microtransit, and mobile ticketing so people can navigate a city without owning a car. Founded by Sam Vermette and Guillaume Campagna, Transit partners directly with transit agencies who endorse and increasingly sponsor the app for their riders.
Luma AI
Luma AI is a Palo Alto-based generative AI lab building multimodal foundation models that turn text, images, and ideas into video, 3D, and interactive scenes. Its flagship product, Dream Machine, has crossed 30 million users; its Ray3 model was the first reasoning-driven video model to generate native 16-bit HDR. Backed by HUMAIN, NVIDIA, Andreessen Horowitz, AMD, and Amplify, the company is racing toward what its founders call 'unified general intelligence' for the physical world.
DatologyAI
DatologyAI builds an automated data curation platform that helps companies train better AI models faster, smaller, and cheaper. Founded in 2023 by former Meta AI, DeepMind and MosaicML researchers, the Redwood City startup has raised $57.6M to industrialize the messy art of preparing petabyte-scale training data.
