Vanderbuild

Vanderbuild is a B2B growth agency founded in 2022 in Poland, specializing in outbound infrastructure, GTM execution, and CRM data automation. We help B2B companies generate leads and convert them into pipeline - fast, before intent goes cold.

We build end-to-end outbound systems: from data enrichment and ICP targeting to personalized multichannel sequences and CRM automation. Our work combines strategic GTM thinking with hands-on execution across Clay, Instantly, HeyReach, Prospeo, and Pipedrive. Every campaign is backed by clean data, tight segmentation, and messaging built around buying signals - not spray-and-pray volume.

What we deliver. We run the full spectrum of outbound and pipeline operations: TAM-based outbound campaigns - systematic market coverage built from total addressable market mapping; Buying signals campaigns - sequences triggered by intent data and real-time account activity; Product-market fit validation - rapid outbound testing to pressure-check positioning and ICP assumptions; LinkedIn network nurturing - structured relationship-building programs at scale; Lost opportunities nurturing - re-engagement of churned or stalled pipeline; Accounts intelligence monitoring - ongoing signal tracking across target accounts; Automated lead qualification - CRM workflows that score and route leads without manual effort.

Track record. 258 campaigns delivered in 2025. 8.2% average conversion rate. 158 GTM workflows implemented across client stacks.

Who we work with. We serve SaaS companies, software houses, and agencies - from SMB to Enterprise - across CEE, DACH, Nordics, Benelux, Baltics, UK, and North America.
