The Challenge
A Series B Munich B2B SaaS was spending €94k per year on HubSpot Enterprise but using roughly 15% of it. GDPR compliance was a constant battle with US-hosted tools — DPOs pushing back, enterprise customers demanding EU-only data residency, and legal blocking campaigns. The marketing team wanted a purpose-built platform owned in-house.
Our Solution
We built a custom marketing automation platform hosted entirely on EU infrastructure (Frankfurt AWS region + Resend EU). Visual drag-and-drop funnel builder, behavioral lead scoring, multi-channel drip sequences (email + SMS), full contact timelines synced to their CRM, and a GDPR consent engine with field-level encryption, right-to-be-forgotten automation, and proof-of-consent audit trails.
What we delivered
MQLs grew 3.2× in 6 months thanks to sharper sequencing and scoring
€54k saved per year by replacing HubSpot Enterprise licensing
99.1% email deliverability after custom IP warm-up strategy
Passed full GDPR audit — customer data never leaves the EU
“HubSpot was slowly strangling us with price hikes. The custom platform pays for itself every quarter — and we actually use every feature we built.”
