Finally, a HubSpot partner who actually builds things

We came to Black Box Digital with a HubSpot setup that looked fine on the surface but wasn't doing anything useful. Marcel and the team didn't just tidy it up — they rebuilt it with AI workflows that actually run the commercial side of the business. Lead enrichment, follow-up sequences, pipeline automation — it all just works now without someone babysitting it. What sets them apart is that they've done this for their own businesses first. You're not getting theory; you're getting a system that's already been proven at scale. The free AI Playbook alone was worth the conversation — genuinely useful, no pitch attached. If you want your CRM to generate revenue instead of just storing contacts, these are the people to call.

Built and manages Mummu Cycling's HubSpot instance across Sales Hub Pro and Marketing Hub Pro

Black Box Digital built and manages Mummu Cycling's HubSpot instance across Sales Hub Pro and Marketing Hub Pro. Marcel delivered a custom Airwallex payment integration that handles our multi-currency tour bookings cleanly, built out the pipeline workflows and automation we use to manage enquiries through to confirmed tours, and set up the sales templates our team uses every day. The Airwallex work in particular was something no other HubSpot partner we spoke to could deliver. Marcel built it, it works, and it has saved us significant manual reconciliation across multiple currencies. What I value most is that Marcel is an operator who runs these systems himself. When something needs to change, the turnaround is hours, not weeks. Highly recommended for founders who need a senior pair of hands on HubSpot.
