HubSpot Architecture Pros

Three Ventures helped us build a Multi-Brand GTM machine from the ground up. When we decided to run our entire venture portfolio out of a single HubSpot Enterprise account, we knew what we wanted, but we lacked a playbook for how to get there. Three Ventures built our multi-brand GTM infrastructure inside a single HubSpot Enterprise account, implementing a custom data model with automated brand-to-contact associations and separate pipelines so each founder had their own GTM environment without needing separate accounts. They created a repeatable onboarding process including checklists, Loom walkthroughs, templates, and permission sets, so that launching a new brand became a defined, repeatable process. They integrated Apollo, AISDR, Maxio, Google and Meta Ads, then layered in tracking and a custom lead scoring model that gave venture leaders real pipeline visibility without disrupting lifecycle stages across the portfolio. Global dashboards with venture-specific filters and executive-level views meant leadership could monitor everything at a glance while each founder stayed focused on their own numbers. They were responsive when issues came up and transparent throughout. If you're running an accelerator, holding company, or multi-brand portfolio and need HubSpot to actually scale across all of it, this is the team that's solved that problem.

HubSpot Overhaul That Actually Moved the Needle

We had been on HubSpot for about eight years by the time we engaged with 3 Ventures. That meant they weren’t working with a blank slate, they had to navigate an environment with existing data, structures, and legacy processes already in place. That can make things more complex, but they didn’t skip a beat. We brought them in as part of a larger shift. We had recently moved off Dynamics and made HubSpot our primary CRM. Since we use Acumatica as our ERP, that move surfaced a whole set of integration and workflow challenges. There’s no native HubSpot integration for Acumatica unless you’re using Acumatica CRM, which we weren’t. 3 Ventures solved that with a custom application that takes data exported from Acumatica and plugs it into HubSpot cleanly and reliably. They also built custom properties and workflows that mirrored how we actually store and use data, and they trained our sales team to use it effectively. The transition felt seamless. They went further than just setup. They helped us unlock value from the data we already had by building custom segmented lists using the ERP data, allowing us to market additional services to existing clients in a way we hadn’t been able to before. They also gave us a full framework to nurture new leads who come through gated content on our site via sales sequences in HubSpot. What stood out most was their approach. They didn’t just dive into the tool. They took time to understand our business and then built solutions from the ground up based on that understanding. It wasn’t about forcing HubSpot to work in a certain way. It was about aligning the tool to our business in the smartest way possible. Because of their work, we’re now in a much stronger position to attract new clients and drive revenue. We’re also finally able to capture and use data from our ERP in ways that influence and support existing client relationships. Personally, I couldn’t be happier with our experience. The team was sharp, communicative, and deeply knowledgeable, not just about HubSpot, but also the business side of what we were trying to achieve. I’d recommend them fully. And if anyone’s on the fence, I’m happy to take a call and walk through what they did for us.
