About
S&P Consulting is a senior-only growth partner for B2B service businesses across the DACH region. The team, 18 senior consultants under founder Jonas Strambach, runs the full S&P Marktführer System: from premium positioning and Meta, Google and LinkedIn campaigns through to structured sales processes, CRM automation and recruiting.
The agency works with coaches, consultants, agencies, tax firms and similar service businesses that want predictable lead generation instead of relying on referrals.
Engagements are done-for-you, not advisory. The team owns ads, funnels, sales process and recruiting end-to-end so founders can focus on delivery.
What they do
Done-for-you growth across the entire system, not just ad management.
Senior media buyers on each platform with full transparency on cost per lead and cost per deal.
Funnels, landing pages and lead qualification built so cold traffic turns into pre-qualified sales calls.
Structured sales sprints, follow-up automation and CRM stages so no lead falls through the cracks.
Hire the team you need to scale: A-players sourced and qualified through a proven recruiting funnel.
