Company Overview

About Wasp

Wasp is a Zagreb, Croatia-based full-stack web development framework — backed by Y Combinator (W21) with $5.2 million in total funding including a $3.7 million round in late 2024 led by HV Capital with Fifth Quarter Ventures, Big Bets, and Metis Ventures, plus a $1.5 million seed in 2021 — providing web developers with a declarative domain-specific language and full-stack scaffolding that generates React, Node.js, and Prisma boilerplate from high-level configuration, enabling developers to build full-stack web applications significantly faster by eliminating the repetitive setup code that every web project requires. Founded in 2020 by twin brothers Martin and Matija Šošić, Wasp serves developers who want the flexibility of React/Node without the boilerplate overhead of setting up authentication, routing, database ORM integration, and API wiring from scratch.

Business Model & Competitive Advantage

Wasp's full-stack framework addresses the configuration overhead that slows web application development: a developer starting a new full-stack web app with React and Node.js must configure a build system (Webpack or Vite), set up TypeScript, wire up a database ORM (Prisma or Sequelize), implement authentication (session management, JWT tokens, OAuth flows), configure routing on both client and server, set up a form validation system, and establish the API contract between frontend and backend — before writing a single line of business logic. This 2-3 day setup cost is repeated for every new project. Wasp's declarative configuration file (specifying the application's entities, pages, routes, authentication method, and actions in a high-level DSL) generates all this boilerplate automatically, producing a working full-stack skeleton that developers then fill with their application-specific logic. The compiler approach (Wasp compiles to standard React/Node/Prisma code) means developers aren't locked into a Wasp-specific runtime.

Competitive Landscape 2025–2026

In 2025, Wasp competes in the full-stack framework, web development tooling, and developer productivity market with Next.js (Vercel's React framework, dominant full-stack React), Remix (React framework, acquired by Shopify), and RedwoodJS (full-stack JavaScript, $12M raised) for web developer full-stack framework and rapid web application development platform adoption. HV Capital's investment (HV Capital is a leading European VC with portfolio including Zalando and SumUp) reflects developer tooling conviction in the European startup ecosystem. Y Combinator W21 backing connects Wasp with the developer tools investment community. The 2025 strategy focuses on growing the indie hacker and solopreneur segment (where boilerplate elimination has the highest time-to-value impact), building the AI-assisted component generation for accelerated feature development, and expanding the deployment integration with Railway, Fly.io, and Vercel for one-command full-stack deployment.
