Top Tech Startups in California, US in 2027

River is the first social app that works for you, not the algorithms. Search, post, chat, call and shop exactly like you do on Facebook, Whatsapp, TikTok, or ChatGPT—only every data point you share is permissioned, bank-grade encrypted, and pays you a cut when brands want access. One tap to consent, one tap to cash in. Same fun scroll, none of the silent surveillance.

We’re building Reflow, a workforce and workflow intelligence platform that helps teams understand and improve how work gets done.

Titan operates 5 companies and has over 300 employees globally. We're changing the way we work, and think about some of the biggest industries. Come be part of the change with us!

AutoScreen is a Software as a Service (SaaS) application that helps hiring teams automate the process of conducting screening interviews. It enables recruiters to set up job descriptions and interview questions, and candidates can respond to these questions at their convenience by recording their video responses. It then transcribes the video responses into text, evaluates and scores the responses.

We are a US-based technology company who creates applications for our customers. Our customers, 97% of them, belong to the Fortune 500 companies which are the largest companies in the world. We personally talk to our customers and demonstrate what value we give them. Our goal is to provide our customers applications to make their job easier.

Construction is one of the largest industries in the world, but it is also one of the least technologically innovative spaces. Conducting fast and accurate cost estimates is a massive pain point because of the tedious nature of takeoffs (measuring & counting materials needed from the drawings). Bobyard automates the construction takeoff process with CV and NLP models to make cost estimates 10x faster while eliminating mistakes. We are a lean startup backed by some of the best VCs in the world: 8VC, Primary, and Pear. Almost all of the work lies ahead of us. We are excited to create next-gen software for the built world!
