What a16z partners are excited to fund
Andreessen Horowitz's "Big Ideas" series captures what their partners are most excited to fund. The 2026 edition reveals a clear shift: AI is moving from experimentation to production. It's no longer a separate project—it's the foundation of everything.
Two major themes emerge: renewed interest in the physical world after two decades of digital product dominance, and the transition from interfaces designed for humans to systems optimized for AI agents.
a16z raised a record-breaking $15 billion across five funds in January 2026, with $3.5 billion dedicated to AI applications. They're betting big on this thesis.
a16z believes the physical world is coming back into focus. Nuclear energy is resurging driven by AI data center demand. Space technology is enabling data centers and biomedical labs in microgravity. Defense systems are becoming decentralized with edge-based autonomous drones.
Key opportunities include nuclear power infrastructure, hardware-software integration for autonomous systems, and earth observation commercialization.
The success of GLP-1 drugs shows what's possible when breakthrough therapies reach big markets. a16z is looking for startups targeting common diseases—cardiometabolic, autoimmune, neurological—using engineered cell therapies and novel modalities.
Consumer health tech is democratizing access through AI-powered analysis, wearables, and accessible full-body screening. Healthcare AI can serve as "super staffing" to address workforce shortages.
Real-time AI applications are emerging: live video-to-video generation, AI bandmates, interactive educational tools. Specialized video generation is being optimized for specific use cases—product marketing, cinematic film, hyperrealistic avatars.
The "personal AI brain" concept is gaining traction: apps that convert digital exhaust (messages, emails, tweets) into personalized decision-making and memory tools.
AI agents need economic infrastructure. a16z sees opportunities in enabling autonomous AI entities to custody wallets and transact across decentralized networks independently.
Sybil resistance and identity verification are critical as deepfakes proliferate. Stablecoin payment infrastructure is ready for enterprise adoption. DAOs are getting proper legal frameworks through DUNA structures.
AI won't truly transform financial services until we rebuild the infrastructure. a16z is looking for regulation-as-code systems that automate compliance, AI-powered systems that replace legacy CRM and ERP, and defensible AI products with real moats.
The winning companies build "data-to-action" platforms—AI that not only captures data but suggests and executes actions.
