Klavis AI is a Y Combinator (X25) backed startup providing open-source infrastructure for integrating Model Context Protocols (MCPs) into AI applications at scale. Founded by Xiangkai Zeng (ex-Google DeepMind, Gemini function calling) and Zihao Lin (ex-Lyft), we solve the critical challenges of tool connectivity, security, and scalability for AI agents. Our platform addresses key industry problems: the lack of built-in, user-based authentication in existing MCP servers and the instability of underdeveloped personal projects. Our flagship product, Strata, enables AI agents to handle thousands of tools through progressive discovery, preventing context overload. This approach is proven to improve agent accuracy on complex tasks by over 13%, achieving 83%+ accuracy on multi-app workflows. Klavis AI provides 100+ production-ready MCP servers with enterprise OAuth support for major services like GitHub, Slack, and Salesforce, with flexible deployment options including a hosted service, self-hosted Docker, SDKs (Python/TypeScript), and a direct REST API.

Fystack features and specs

  • Modern Tech Stack
    Fystack appears to offer a modern, integrated technology stack designed to help developers build full-stack applications efficiently, leveraging contemporary frameworks and tools.
  • Full-Stack Solution
    Fystack aims to provide a comprehensive full-stack development platform, reducing the need to piece together multiple disparate technologies for frontend, backend, and infrastructure.
  • Developer Productivity
    By bundling commonly needed tools and configurations together, Fystack can potentially accelerate development workflows and reduce boilerplate setup time for new projects.
  • Streamlined Development Experience
    Fystack seeks to offer a cohesive developer experience where components are designed to work together seamlessly, reducing integration headaches common with assembling custom stacks.
  • Opinionated Architecture
    Having an opinionated stack can be a benefit for teams that want clear conventions and best practices baked in, reducing decision fatigue and ensuring consistency across projects.

Possible disadvantages of Fystack

  • Limited Community and Ecosystem
    As a relatively niche or lesser-known platform, Fystack likely has a smaller community compared to mainstream frameworks, meaning fewer tutorials, plugins, third-party integrations, and community support resources.
  • Vendor Lock-in Risk
    Adopting a bundled stack like Fystack may create dependency on its specific tooling and conventions, making it harder to migrate away or swap out individual components if needs change.
  • Limited Track Record
    Fystack does not have the extensive production track record of more established technologies, which may raise concerns about long-term stability, maintenance, and enterprise readiness.
  • Reduced Flexibility
    An opinionated, integrated stack can limit flexibility when developers need to customize or deviate from the prescribed architecture, potentially making edge cases or unique requirements harder to implement.
  • Learning Curve for Proprietary Patterns
    Developers may need to learn Fystack-specific patterns and conventions that don't directly transfer to other technologies, which could be a concern for team hiring and skill portability.

Businesses choose Fystack to eliminate vendor lock-in and cut engineering costs by $30k–$50k annually. Our unified platform replaces the need for multiple fragmented vendors (custody, compliance, and policy), allowing you to launch on-chain products 10x faster than building in-house.

How would you describe the primary audience of your product?

Fystack's answer:

Our primary audience consists of Web3 Neobanks, Payment Gateways, and B2B Fintechs that need to manage user funds or high-volume corporate treasuries. We specifically serve technical teams and CTOs who demand full control and audibility over their security infrastructure.

What's the story behind your product?

Fystack's answer:

Fystack began as the very first startup idea of our founder, Thi, and evolved from a side project into a singular obsession to fix the broken custody model.

Which are the primary technologies used for building your product?

Fystack's answer:

Fystack is built on advanced Multi-Party Computation (MPC) cryptography, ensuring that private keys are split across nodes and never assembled in one place.
