Why we exist
Built inside an agency that could not see its own results
Before LeadJourney there was S&P Consulting, a performance marketing agency in Mannheim that Jonas Strambach built to 16 employees and more than 2 million euros in annual recurring revenue. It ran Meta, Google, LinkedIn and Bing campaigns for B2B service businesses, coaches and consultants, and set up the CRMs and sales processes behind them.
The agency could see which campaigns produced form fills. It could not see which ones produced customers. Every ad platform claimed the same lead, the CRM told a different story weeks later, and the tools on the market either tracked e-commerce carts or stopped at the lead.
LeadJourney is the tool the agency needed and could not buy: server-side tracking of individual clicks, attribution through the CRM pipeline to closed revenue, and a feedback loop that sends the outcome back to the ad platforms so bidding learns from buyers rather than from leads.
The mission has not changed since the first line of code: give lead generation businesses one truth about where their leads come from and what they are really worth.
