The challenge

Chupenga sells B2B catering to offices and restaurants across DACH. The product had buyers, the team had bandwidth, but the constraint was repeatable demand: how do you keep finding the next 100 high-fit office managers, department heads, or restaurant openings without burning out the team on manual list-building?

What Scalantec built and operates

The engagement is execution-focused. Scalantec runs outbound as a continuous service, not a one-shot campaign. Across 18 months, the team has designed, launched, and iterated on 20 separate campaign plays, organized around two core audiences (Office Managers and Department Heads) and a seasonal calendar. The audience definition was refined across multiple iterations until message-market fit stabilized; the standout audience plays now run at four to seven times the industry midpoint reply rate.

Deliverability discipline holds the system together. Across 19,765 messages sent, the bounce rate sits at 2.86%: well inside the threshold that separates outbound systems that scale from outbound systems that get the sender domain blacklisted by month three. Achieved through tight inbox-warming, multi-domain rotation, and ongoing list hygiene.

The result is a continuously running pipeline channel that produces high-value, recurring clients on its own.
