Marketing systems, websites, and HubSpot campaigns for B2B companies selling to experts

Three Seven works with established B2B companies whose buyers are subject-matter experts — scientists, engineers, and technical specialists across life sciences and biotech, industrial manufacturing, engineering software, cybersecurity, healthcare technology, scientific research, engineering services, medical consulting, and architecture and construction. Based in Ann Arbor, Michigan, the agency works with clients nationally, framing its work as marketing for experts that sell to experts.

The scope covers full marketing systems rather than single deliverables: digital strategy, content strategy, strategy-led custom website design, landing page design, and conversion-focused design work alongside SEO audits and HubSpot implementation. HubSpot work spans setup, strategy, and campaign execution, built to generate traffic, leads, and brand awareness for companies whose sales cycles depend on technical credibility with expert buyers.
