Top Tech Startups in California, US in 2026

There is a $2T backlog of legacy enterprise systems blocking AI adoption. It's humanly impossible to clear manually. At Gallop Intelligence, we are building AI agents to modernize these systems for Fortune 500 companies. We are founded by veterans from Lovable, Google, and Amazon, and we are moving fast.

Alhena AI (formerly known as Gleen AI) is an all-in-one conversational e-commerce AI concierge designed to turn customer experience into revenue. Founded by ex-LinkedIn engineers, it orchestrates multiple specialized, vertical models rather than relying on a single generic LLM to ensure 100% hallucination-free, brand-aligned interactions across the entire buyer journey

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.

Lunar is a stealth hospital technology company building a new type of software platform for hospitals. Built on a foundation of two years of research and development, the Lunar cloud platform brings state-of-the-art technology to solve some of the most frustrating challenges faced by hospitals today. The company focuses on using smarter automation, better data, and sensible machine learning to empower hospitals with the tools to provide more precise and effective care, doing things they can't today. This next-generation platform is a fundamental rebuild of the information infrastructure that runs health systems. All of it – from doctors, nurses, pharmacists, lab technicians, coders, billers, supply chain, and even patients – Lunar’s software powers everything, soup-to-nuts. We believe that this mission is the moon landing of healthcare – something so consequential and ambitious that most people believe it to be impossible. Backed by Silicon Valley’s preeminent venture capital firms, we believe in the power of a small, high performance team of seasoned professionals operating at the peak of their abilities. We value people who are driven, curious, have sound judgement, and care about doing the best work of their careers.
