Act 1
The Threshold
In 2019, JB Warranties had built a thriving business in a niche most people don't think about: extended service contracts and warranty programs for plumbing and HVAC systems, sold through contractors. They'd grown through outbound selling, word-of-mouth, and industry awards. By every internal measure, the business was working. (They've since been named to Inc.'s Best Workplaces list six times, most recently in 2025.)
What they didn't have was a marketing function. No marketing staff. No marketing automation. No social presence. No blog. No SEO strategy. No way to warm up a lead before sales reached out.
They were considering ActiveCampaign. A referral from a former colleague at another client pointed them to us, and the conversation shifted from "what tool do we buy?" to "how do we build the marketing function and support it with HubSpot Marketing Hub?"
By 2019, JB Warranties had become a leader in our industry, but our growth had been driven by outbound, referrals, and reputation. To keep scaling, we knew we needed to show up where our customers were actually looking. Bringing in The B2B Mix wasn't about buying a marketing tool — it was about building a marketing function we'd never had.
The takeaway. Family-built B2B companies don't fail to modernize because they're stuck. Many fail to modernize because they're successful enough that the gap doesn't feel urgent. The threshold moment is rarely a crisis. It's usually a quiet realization that the next chapter requires capabilities the current company doesn't have, and at JB Warranties, that realization came from operational leadership recognizing the gap, not from a marketing-led pitch.
Act 2
Marketing by committee and why we channeled it instead of suppressing it
The first step for JB Warranties was the implementation of HubSpot Marketing Pro Hub. That was the easy part.
There was no marketing department. There was no Marketing Director. What there was, however, was a tight-knit team of people who genuinely loved the company—the kind of culture that puts you on Inc.'s Best Workplaces list six times—and wanted to be involved in shaping how it presented itself to the world.
Every blog post, every social post, every email touched five opinions. Everyone had ideas. Everyone meant well. And every decision took longer than it should have because the company hadn't yet developed marketing decision-making muscles.
Three principles that worked:
Principle 1: Channel enthusiasm; don't suppress it.
The agency instinct is to push back: "Just let us do our work." That's a mistake. The enthusiasm is the company's culture. It's exactly what built JB Warranties into a six-time best-workplace and a category leader. The work is to create structures that channel input productively instead of treating it as noise: content review processes, defined approval roles, editorial cadences.
Principle 2: The "voice vs. veto" distinction.
Not every opinion is equal weight. People with stake get a voice. People with accountability get a veto. Most marketing-by-committee dysfunction comes from confusing the two. Getting this distinction explicit early saves projects.
Principle 3: Build the muscle, then hire the leader.
This is the moment most agency-client relationships blow up. A marketing leader joins, the agency feels threatened, the leader feels constrained, the work becomes adversarial. That didn't happen here.
Two years in, JB Warranties hired Matt Cosby as Marketing Director. Matt's arrival unlocked what was possible. JB Warranties upgraded from Marketing Hub Pro to Enterprise, added Sales Hub, Service Hub, Operations Hub, and HubSpot CMS, and migrated their website from WordPress to HubSpot.
The takeaway. The agency's job at a company without internal marketing leadership isn't to be the marketing leader forever. It's to build the operational muscle that makes a future leader's job possible. When that leader arrives, the relationship has to evolve, and the agencies that handle this transition well are the ones that built for it from day one.
Act 3
What's possible now
The early wins (first 12–24 months):
- 63% increase in LinkedIn followers, 110% in comments, 53% in shares
- 7,500% increase in Facebook engagement
- 106% increase in Instagram followers, 95% in X/Twitter
- 14 keywords moved from page 10+ rankings into Google Top 10 within the first three months of working together
- Year 2 actuals beat goal by 14% on organic search sessions and 52% on social-driven website sessions
When Matt joined in 2021, the partnership shifted gears. With internal marketing leadership in place, we could go deeper into the systems and infrastructure that the early phase had set the stage for:
- Centralized marketing, sales, service, and operations data on HubSpot
- A new HubSpot CMS website replacing WordPress
- End-to-end reporting that connects the customer journey from first touch to renewal
- Custom Event Request and Event Feedback objects in HubSpot — sales reps submit upcoming events, internal teams trigger booth signage and materials, post-event surveys capture cost-per-lead and qualitative feedback, and dashboards show event ROI in real time. The kind of build most agencies don't take on.
Imagine having an independent marketing department outside your office door. Now, imagine getting top-tier service and results without the exhausted itemized and bloated pricing you get from big marketing shops located in high rises and big cities. Having led marketing for a 5,000 employee multi-billion-dollar company, and now working at a smaller company as a Marketing Leader, I couldn't ask for better results and responsiveness on our projects.
Since partnering with The B2B Mix, we've seen a significant increase in brand visibility, lead generation, and overall engagement. They consistently deliver high-quality work, communicate clearly, and adapt quickly to our evolving needs. It's rare to find a partner who is not only highly skilled but also genuinely invested in your success.
If your business is in this place
Family-built. Successful. Considering modernization but cautious about losing what made the company special. The work doesn't have to start with a tool decision or a hire. It can start with a conversation.
