Captain Data
Fresh B2B data, piped anywhere
What is Captain Data
Captain Data fetches, enriches, and extracts B2B data in real time by automating scraping across LinkedIn and other web sources, exposing the results through a structured API. It's built for GTM Engineers, RevOps teams, and GTM Leads at mid-market and enterprise companies who need to move large volumes of contact and firmographic data without manual intervention. The standout capability is pulling full employee lists for any company on demand — useful for building account-level coverage maps or feeding headcount signals into scoring models. Pricing starts at €600/month for 20,000 credits, which makes it a mid-budget commitment; teams running low-volume pilots or one-off enrichment jobs will find the credit model adds up quickly before they see meaningful scale.

Vanderbuild take
Captain Data sits at the infrastructure layer of data enrichment and prospecting — it's the tool you reach for when you need to automate LinkedIn scraping, enrich at volume, and pipe the output into your CRM or AI workflow without stitching together brittle workarounds. If you're serious about agentic outbound, this is non-negotiable: the MCP server makes it especially usable as an orchestration layer for AI agents, and the native API means you can wire it into any stack without UI dependency. Budget for an experienced operator — vanilla setup leaves value on the table, and the credit-based pricing at €600/month entry means you'll want someone who can optimize query patterns before the bill scales. The integration surface is thin outside HubSpot and Google Sheets, so if your stack runs on Salesforce or a custom CRM, expect to do that plumbing yourself via API.
