Where the name comes from
In hockey, the fourth line is the group that outworks everyone, wins the battles along the boards, and rarely gets the spotlight. We named the company after that mindset.
It shows up in how we work: fewer vanity metrics and award submissions, more qualified leads, calls, sales, and visibility in AI search.

You work directly with the people who plan, build, and run your marketing.
Kevin Entmaa
Founder
Kevin leads strategy for every client. He started in tech consulting, rolling out CRM, project management, marketing automation, and digital asset management platforms for major global brands.
Off the clock, he's a music nerd who plays drums and guitar, a former pro hockey goalie, an F1 fan, and a mediocre golfer at best. He loves to travel and is outnumbered at home by his Mini Aussie, Lilo, and Schnoodle, Chester.
Brian Bachnak
Head of Business Development
Brian is a people person through and through. He's the first point of contact for new clients and makes sure every company lands on the right plan for its goals.
Before 4th Line, Brian played professional hockey, and these days he gives back by coaching young players just starting out in the game. He's a die-hard Detroit sports fan who never misses a Lions game, usually with his Mini Aussie, Maple, close by.
How We Work
Principles that don't change per client.
01
One team, one set of numbers
SEO, AI search, ads, lead follow-up, and your website all report into one clear set of numbers: leads, calls, cost per lead, and sales.
02
Straight talk over pretty decks
If a channel isn't producing, we say so and shift the plan — before the invoice, not after.
03
Built for where search is going
We design content, tracking, and systems around AI Overviews and answer engines now, not as an afterthought later.
04
Small enough to actually know your business
We work with a limited number of clients at a time so every account gets real strategic attention, not a rotating junior account manager.
