Apollo Atomics focuses on shrinking and mass-manufacturing the steam generator—the largest component in many nuclear plants—by using a compact metal block with needle-thin channels to transfer heat more efficiently. Its design, based on MIT research, enabled the company to build a reactor it says is roughly 40-times smaller than ones using conventional steam generators and to assemble systems in a factory rather than on site. Apollo has built a 40-kilowatt demonstration reactor at MIT and plans to offer reactor sizes from about 10 megawatts-electric up to 300 megawatts. The company projects it can build a 300 MW plant in under 24 months and estimates the reactor will cost four to five times less to produce than existing designs. Apollo targets a levelized cost of electricity near 3 cents per kilowatt-hour and aims for commercial deployment in 2028. It participated in Y Combinator’s Spring 2026 batch.

CodeRabbit offers an automated platform that uses AI agents to review freshly generated code in real time, catching syntax errors, logic bugs and security vulnerabilities as code is created. The company has expanded its offering with Agentic Change Management, which includes CodeRabbit Triage for scoring and routing pull requests, Change Stack for visualizing a change's impact on system behavior and dependencies, and CodeRabbit Security for full-repository scanning and continuous monitoring after code ships. Its tools validate incoming pull requests using repository-wide context and sandboxed test environments, and can generate recommended fixes that re-enter the pull request workflow. CodeRabbit has positioned the product to help teams prioritize and govern a rising volume of code changes originating from developers, nontechnical staff and automated agents. The company announced a $143 million Series C to accelerate these product capabilities and scale adoption. Prior investors such as CRV, Scale Venture Partners, Flex Capital and Pelion Venture Partners participated in the latest round.
