Top Tech Startups in California, US in 2026

Reunion is the leading platform for clean energy tax credits and compliance. Since 2024, we have worked with major corporations to invest over $7 billion in clean energy projects, including some of the industry's largest tax credit transactions. We are a fast-growing and profitable company, and our expert 25-person team knows how to get things done and loves to move fast! Our founders, Billy Lee and Andy Moon, are second-time entrepreneurs and were early pioneers in solar tax equity and project finance. We have recruited an experienced team of early executives from SunEdison, SolarCity, Tesla, GoodLeap, and other leading clean energy companies. We have built a strong company culture which values collaboration and speed… while still having fun. In 2025, we launched Reunion PWA, a software solution that helps developers comply with prevailing wage and apprenticeship (PWA) requirements to unlock the full value of clean energy tax credits. Reunion PWA is rapidly gaining traction in the market, and we’re growing our team to accelerate adoption and expand to additional compliance offerings. Join us in the fight against climate change by helping renewable energy developers build faster!

The Problem: For 30 years, the industry has relied on dedicated hardware acceleration (like Intel AES-NI) to mask the inefficiency of legacy algorithms. As computing moves off traditional servers and onto diverse ARM and RISC-V edge devices, that hardware crutch is disappearing. Legacy cryptography (AES/SHA) is now too heavy for resource-constrained devices and acts as a massive bottleneck for real-time AI data ingestion. Our Solution: We have engineered the TRV Monolith—a paradigm-shifting, post-quantum cryptographic engine built entirely on our proprietary Boolean Transformation Gate System (BTGS). Built completely in native Rust, the engine operates with deterministic execution behavior, zero dynamic heap allocation, and is 100% dependency-free (no reliance on external libraries). It relies exclusively on symmetric state-transformation and non-linear Boolean Circuit Satisfiability, . This breakthrough allows us to solve three massive market mandates: The IoT & Edge Explosion: Running natively on edge hardware without dangerous compromises or heavy runtimes. The Sovereign Tech Mandate: Providing independent, verifiable cryptographic architectures to escape legacy vendor lock-in. The AI Data Pipeline: Securing massive real-time AI data harnesses without slowing down large language models (LLMs).
