Top Tech Startups in California, US in 2027

About our tech: With over 50 patents, ANELLO uses Silicon Photonics to dramatically reduce the size, weight, and power (+cost) of the fiber-optic gyroscope (FOG) typically required in submarines and large aircraft for measuring the most precise system balance for navigation. We call this new version of a FOG, a SiPhOG. We're building self-contained navigation systems (IMU&INS) with our SiPhOGs at a fraction of the size, weight, cost, and power of FOGs. We're bringing the navigation precision in GPS-denied environments that submarines have to autonomous devices for any use case (air, land, sea). Our products are dual use for commercial and defense customers. We are a profitable Series-B start-up shipping product for just the past 2.5 years, just 40 ppl. Our company culture is very collaborative and allows for the ability to own and contribute on multiple NPI products, while leaning more into other areas of technical interest. We have multiple products heading into high-volume production, with additional products at earlier stages of the lifecycle (including concept mode). We're backed by powerhouse companies like In-Q-Tel, Lockheed, and MESH. There is great interest in our technology and in a short time have strong revenue and designed into into many autonomous platforms in dynamic segments like Autonomous Maritime and Aerial, Construction/Mining, AgTech, Robotics. We have a very collaborative culture that promotes learning and innovation + we believe there is significant financial equity upside here given our revenue trajectory.

Parker is the AI creative director built to produce the highest-performing ads on the internet. Every company needs to grow. That's not new. What is new is that AI is about to create more companies than the world has ever seen, and every single one of them will eventually need to find customers. That problem isn't going anywhere. If anything, it's getting bigger. There are thousands of ad agencies built to solve it. A handful are great. Most are honestly pretty bad. And none of them scale past the people who work there. The idea behind Parker is simple: what if there's one agency that's as good as the best in the world, except it runs in software instead of people? We launched. We went viral. We've grown 10x since January. Top brands like LiquidIV, Gruns, and Legends now rely on Parker to create ads that actually win. We're not building just another AI tool. We're building the default answer to the question every company eventually asks: who's going to help us grow? We're a small team of people who deeply love their craft. Engineers who love to build, creative strategists who live for a great ad, and marketers obsessed with growth. We don't just work on this. We love what we're working on. If that sounds like you, we'd like to meet you.
