KLAPPR

KLAPPR is an Amsterdam-based accelerator and B2B go-to-market partner for early-stage technology founders. It works hands-on on founder-led sales, positioning, websites, marketing, sales systems, CRM and automation to help B2B startups build repeatable commercial engines. The firm is most relevant for early-stage B2B, SaaS and technology-services companies seeking operational go-to-market support rather than a traditional venture capital investor.
