Top Tech Startups in California, US in 2027

“The smartest purchase starts before you click ‘Buy.’” That simple idea is why we’re building Cheaper.com. We’re creating a smarter way to shop online—one place where people can discover products, compare prices, ratings, and reviews, and buy with confidence. Today, finding the right product often means opening multiple websites, comparing prices manually, checking reviews separately, and still wondering whether you found the right deal. We believe shopping shouldn’t feel like detective work. We bring discovery, comparison, and purchasing together. On Cheaper, shoppers can explore products across categories, compare their options, evaluate sellers and product information, and purchase directly through our marketplace. But we’re not building only for shoppers. “A great marketplace works for both sides.” We’re giving sellers a place to list their products, showcase what they offer, reach potential customers, and grow their online presence. Whether they are already selling online or looking for another digital channel, we want to make reaching customers simpler. And for us, “cheaper” isn’t just about finding the lowest price. It’s about finding better value. Price matters—but so do ratings, reviews, product details, sellers, and the overall buying experience. We want to give people the information they need to make choices that make sense for them. We’re starting across Electronics, Fashion, Home & Living, Kitchen, Sports, and Books, and we’re building toward a marketplace that can grow far beyond these categories. Technology is at the core of our journey. We’re continuously working toward smarter search, better product discovery, personalized recommendations, powerful seller tools, and a smoother buying experience. Our mission is simple: help people shop smarter and help sellers sell more. We’re not trying to add another complicated step to online shopping. We’re trying to remove them. Discover. Compare. Buy. That’s Cheaper.com.

Who we are We are quant traders and engineers from high-frequency derivatives markets, where every small detail matters for getting the best price and outcome. We researched, built, traded, and risk-managed complex trading systems at scale, which shaped our obsession with efficiency. Today, the same AI model can be served by different providers with different prices, latencies, cache behaviors, model quality, and reliability profiles. We know how small differences compound, and we built Auriko to optimize across them. Our mission We're building the market infrastructure for the AI inference economy. Our goal is to make compute a liquid, efficiently utilized, transparently priced, and risk-manageable resource.

StarSpark.AI is building a personal AI teacher for every student—starting with math. We’re creating a learning-first platform that combines strong pedagogy, thoughtful product design, and AI to help students build durable understanding (not just “get answers”). Our goal is simple: make learning feel clearer, more confident, and more effective—for students, with the trust and visibility parents and educators need.
