Builders Tech Stack

Venture studio backing founders building enterprise software and AI companies

Venture Capital and Private Equity Principals Rotterdam 11–50 employees Founded 2021 Privately Held

Builders is a venture studio (not a traditional VC fund) investing in early-stage founders building enterprise software and AI products. The tech stack reveals heavy LLM integration (LangChain, LangGraph, OpenAI, Anthropic, Claude) paired with modern full-stack tooling (Next.js, Node.js, PostgreSQL, Neo4j), suggesting the studio itself is actively building prototypes and validation tools. Leadership gaps around technical execution—evident in hiring for senior engineers and an explicit pain point around lack of strong technical leadership—indicate the studio is scaling its internal build capability to support portfolio founders.

About Builders

Builders operates as a venture studio based in Rotterdam, partnering with founders from day zero to build enterprise software and AI companies. The model combines early-stage capital with hands-on execution support: the studio provides rapid validation playbooks, brings in experienced technical leadership (CTOs), and supplies capital for the first 12 months. A 7-person engineering team and 4 executive roles (including c-level hires) reflect the studio's emphasis on active product building and governance. Current pain points—fragmented workflows, manual operations, and reliance on spreadsheets for workforce data—suggest internal scaling challenges typical of a young studio managing multiple concurrent portfolio companies.
