Vainu Tech Stack

Nordic company data platform for sales and marketing intelligence

Technology, Information and Internet Helsinki 51–200 employees Founded 2014 Privately Held

Vainu packages Nordic company data for sales, marketing, and operations teams via APIs and integrations into CRM/marketing stacks (HubSpot, Salesforce, Pipedrive). The tech stack reveals a shift toward AI-first workflows: they're adopting n8n for workflow automation and Claude for reasoning, building agentic systems for GTM tasks and state-machine-based LLM orchestration. The hiring mix—sales-heavy with one engineer—signals a sales-led GTM rather than a platform-first motion, consistent with projects around prospecting product sales and event marketing in Sweden.
