Vanderbuild is a GTM engineering and outbound agency from Poland. We build sales systems that turn data into a steady flow of B2B meetings.
Most outbound fails because it fires at the whole market once and stops. Only 5 to 10% of your ICP is ready to buy at any moment, so we build systems that keep coming back at the right time.
How we work, in four stages:
- PMF validation: we test up to 10 sales theses in live cold email and LinkedIn campaigns and tell you what to keep, change or drop.
- TAM mapping: we count, qualify and reach your whole addressable market.
- Signal-based campaigns: outreach triggered by buying signals such as hiring, funding, leadership changes, tenders and events.
- CRM data activation: the data you already own starts producing pipeline.
We work with B2B SaaS companies, service based businesses, outsourcing firms and industrial B2B companies selling across Europe and North America.
We don’t sell hours. We build systems, and you keep everything we build: the market database, sequences, prompts and workflows.
Our stack is Claude and Clay-first. Our founder, Mateusz Sekta, is the Clay Cup 2025 Vice Champion, 2nd in the world and 1st in Europe.
