Top Tech Startups in California, US in 2026

There’s a massive transition happening in the video games industry right now. Gaming has become a full-blown cultural movement, and many fail to appreciate how it has already become the dominant form of leisure and entertainment for an entire generation. But as culture has evolved, technology has advanced, and more people have gravitated toward games, the industry incumbents that run the show haven’t kept up. Our big bet is that by empowering game creators with better technology, we'll make the entire ecosystem more welcoming, connected, efficient, creative, and fun for all. We’re an early stage startup backed by Thrive Capital, Griffin Gaming Partners, Ribbit Capital and a16z's inaugural SPEEDRUN class. Our mission is to help game creators achieve independence by building the tools they need to start, run, and scale their businesses.

High growth investor backed startups needing a finance team

Firecrawl is the easiest way to turn the web into data AI agents can use. One API call converts any URL into clean, LLM-ready markdown or structured data - the boring-hard problem everyone building with LLMs eventually hits, solved. We hit 8 figures in ARR in year one and more than doubled it in year two. We have 150k+ GitHub stars, and developers, agents, and category-defining AI companies build on us every day. Growth like this is rare, and we're just getting started. We're a small team punching far above our weight. Everyone here owns a real piece of the product and company, end to end, and runs it themselves - no hiding behind process or headcount. This is a place for people who want to work at the frontier: an AI company building the infrastructure other AI companies run on, not one bolting AI onto an existing product. We move fast, go deep, and are building the tools superintelligence will rely on to gather data from the web.

Our mission is to empower individuals and families to plan for a financially stable future through personalized retirement planning and life insurance solutions. We are committed to providing guidance and clarity in navigating life’s financial milestones, protecting loved ones, and achieving long-term peace of mind. By prioritizing transparency, trust, and tailored strategies, we help our clients build confidence in their financial well-being and security.

Alhena AI (formerly known as Gleen AI) is an all-in-one conversational e-commerce AI concierge designed to turn customer experience into revenue.
