Top Tech Startups in California, US in 2027

We're a stealth team building space hardware at the edge of what's currently possible — high-stakes, flight-grade systems where the engineering bar is unforgiving and the upside is enormous. While we can’t share full details yet, our founding and early engineering team includes talent from SpaceX, Northrop Grumman, and Impulse Space, the group includes people who've pulled off feats almost no one else on Earth has.

The all-in-one liquidity platform for private companies and their shareholders. Buy and sell unicorns and pre-IPO companies.

We’re building the next generation of tactile sensors to help physical AI perceive and interact with the real world. Join us to turn ambitious ideas into hardware that gives intelligent machines a more capable sense of touch.

Axamy is like Muse for whole organizations. We're enabling whole teams and organizations to work together through a shared understanding of their people, goals, decisions, and commitments. Axamy learns through working with people, coordinates across them, and follows through on the work that needs to happen. Our ambition is to eliminate bureaucracy as a method of organizing people that treats them like meatware, discouraging our best qualities like creativity, initiative, and daring. Our technology will make workplaces more human, helping people collaborate while being free to contribute the best of what they have to offer. We’re looking for people who want to help build that company with us.

Footprint is the agentic platform that learns your compliance program, and runs it end-to-end. Our technology helps compliance teams clear their alert backlog faster, with deeper context and better judgment. Financial crime is growing faster than any risk team can hire against it, and most investigations still happen the old way: one analyst, one case, a pile of PDFs and a dozen disconnected tools. We built Percy to change that. Percy doesn't impose a workflow. It learns yours, converts your policies and procedures into agents line by line, and runs them the same way every time, with a full audit trail. When a regulator asks how a decision was made, the answer is already written. Every investigation is grounded in the vendors and data sources our customers already trust, like LexisNexis, ComplyAdvantage and government registries. Each one is committed to an organizational memory that compounds and adapts as procedures change. Our customers include FDIC- and OCC-regulated banks and fintechs such as Bilt, Nuvei and MoonPay. In September we announced a $25M Series B led by QED, with Index, Commerce Ventures and others. We're using it to double our engineering and sales teams in New York and San Francisco.

Infi's mission is to build a general-purpose fully autonomous factory to unlock physical abundance and reindustrialize America. We are a robotics-native contract manufacturer helping hardware companies take their products from prototype to production at our factory in the San Francisco Bay Area. Our initial focus is automated assembly for robots, drones, and other intelligent hardware.

Altimate AI builds DataPilot platform to automate work of data teams using AI agents. DataPilot can generate data pipelines, write data documentation / tests, and optimize data infrastructure autonomously. 100s of companies that use DataPilot have seen 2x accelerated data development and 30% reduction in data infra. costs.

Our core product is a robust and customizable media monitoring tool that produces and delivers daily curated media reports for our customers

Orchard Robotics is a Series A startup backed by top VCs like Quiet Capital, Shine Capital, and General Catalyst. We're securing America’s food supply by building the AI farmer that automates our nation’s farms. We start by collecting the most valuable data for farmers, telling them everything about what is growing on their millions of trees, across thousands of acres of farmland. We do this using advanced camera systems we build, that take pictures of every one of the billions of fruit in a farm. This data lives in our cloud data platform, FruitScope, that we've developed from the ground up to help farmers manage their crops with precision. Farmers across the nation use our industry-leading software to look at their data, make critical decisions, and command farming operations on a daily basis. Our technology is used today across some of the largest farms in the nation.
