Sequoia helps daring founders build legendary companies from idea to IPO and beyond. We aim to be the first true believers in tomorrow’s most consequential companies. We partner with a few outliers each year and go all-in, providing them with the hands-on help required at every stage of the company building journey. Our expertise comes from nearly 50 years of working with legendary founders like Steve Jobs, Elon Musk, Larry Page, Jan Koum, Brian Chesky, Tony Xu, Lin Qiao, Eric Yuan, Christina Cacioppo, and Patrick Collison. In aggregate, Sequoia-backed companies account for more than 30% of NASDAQ's total value. The vast majority of the money we invest has been on behalf of nonprofits and schools like the Ford Foundation, Mayo Clinic and MIT, which means most of the returns we generate benefit these great causes.
The current AI infrastructure build-out represents a historic capital expenditure shift, necessitating a move toward purpose-built data centers that co-optimize hardware, software, and networking. Unlike traditional general-purpose facilities, modern AI data centers require specialized designs to handle massive power d...
Databricks CEO Ali Ghodsi details the transition from academic researcher to corporate leader, emphasizing the necessity of identifying and obsessively focusing on a company's single greatest bottleneck. Scaling a business requires moving beyond initial product-led growth to building a robust enterprise sales engine, w...
Web search is undergoing a fundamental transformation as AI agents replace humans as the primary users of the internet. Parallel Web Systems, founded by former Twitter CEO Parag Agrawal, addresses this shift by building infrastructure specifically for agentic search. Unlike traditional search engines that rely on human...
Reinforcement learning pioneer Rich Sutton and co-founder Khurram Javed argue that the future of artificial intelligence lies in continual, experiential learning rather than static, human-knowledge-dependent models. While large language models represent a significant breakthrough, they remain limited by their inability...
Closing the "experience gap" in AI agents requires a shift toward continual learning, where systems compound in capability through real-world usage. Rather than treating models as static, developers should implement a four-pillar framework: capturing full interaction trees for traceability, utilizing production traffic...
Agentic AI systems rely on a three-part architecture consisting of the model, context, and the harness. The harness serves as the critical orchestration layer, managing the interaction loop between the model and external tools. While general-purpose harnesses suffice for basic tasks, specialized domains require custom ...
Reinforcement Learning (RL) environments represent a critical shift in AI development, moving from simple behavior cloning to complex, expert-driven simulations. These environments integrate realistic digital worlds, high-fidelity application clones, and rigorous task verifiers to train agents on real-world workflows. ...
Post-training serves as a critical strategy for businesses to move beyond generic, off-the-shelf APIs and establish a sustainable competitive moat. By encoding unique domain expertise and product-specific judgment into models, companies achieve superior performance while significantly reducing operational costs. This d...
Building a competitive AI research lab as an application-layer company requires leveraging the existing Frontier ecosystem rather than attempting to out-spend major labs. Success hinges on creating domain-specific benchmarks and utilizing synthetic data generation guided by experts, such as lawyers, to navigate sensiti...
Sovereign AI represents a strategic shift toward companies owning their own intelligence rather than relying solely on external, closed-model APIs. This transition is driven by the need for cost efficiency, reduced latency, superior performance in domain-specific tasks, and greater control over proprietary data. By mov...
Drug discovery is shifting from a serendipitous, trial-and-error process toward a rigorous, engineering-based discipline powered by AI. By applying scaling laws—scaling data, models, and compute—Chai Discovery aims to create a computer-aided design suite for molecules that enables researchers to specify therapeutic pro...
Current AI progress relies heavily on scaling transformer architectures and reinforcement learning, yet these models remain limited by their inability to learn continuously from real-world data after deployment. Transformers suffer from catastrophic forgetting during fine-tuning and lack the computational depth require...
Kareem Amin, CEO of Clay, details his unconventional approach to building a high-growth startup by prioritizing existential clarity, long-term commitment, and a "monk-like" leadership philosophy over traditional, high-anxiety growth tactics. He explains the evolution of "go-to-market engineering" as a category, emphasi...
Anthropic’s developer platform architecture organizes AI capabilities into three distinct layers: knowledge, execution, and coordination. The knowledge layer focuses on model design and parameter standardization, while the execution layer provides managed infrastructure for agentic tasks. The emerging coordination laye...
Zipline has evolved from a niche drone manufacturer into a global autonomous logistics infrastructure provider, treating the physical aircraft as only 15% of the total solution. By vertically integrating the design of over 700 unique components, the company achieves superior reliability and cost-efficiency, enabling it...
Semiconductor research and AI infrastructure development hinge on the critical integration of hardware, software, and model architecture. Dylan Patel, founder of Semi-Analysis, highlights how the industry has shifted from static benchmarking to living performance metrics that account for the rapid evolution of AI model...
AI models currently rely on RAG and context engineering, which are computationally expensive and fail to capture the deep, intuitive understanding required for complex, evolving knowledge work. Engram addresses this by developing "always training" models that utilize adapter fine-tuning to internalize team-specific dat...
