You started your business to build things you're proud of. Not patch revenue leaks.

AI can expand what your business handles without adding headcount. We look at how you actually run, find where it's leaking, and build the fix around you.

Good businesses lose good money to solvable problems.

Where growth leaks

  • Leads go cold fast
  • Follow-ups get messy
  • The sales process is clunky

Where operations leak

  • Potential revenue is leaking
  • Workflow lives in five tools
  • Scattered data means slow decisions

How we work

We are not here to sell you SaaS.

We look at the whole business. Not just marketing. Not just your logistics or your project management. All of it, as one system, so we can see what is lacking, what can improve, and what just needs a little grease on the wheels.

Then we build that fix custom to you, and we stick around to keep it earning its keep.

Most builds run in one of two lanes

Which lane is yours depends on where it hurts.

AI add-ons that compound

Front desk, after-hours, and lead qualification: trained on your business and integrated with your pipeline.

We're local. We show up in person, build in front of you, and pick up the phone when you call. That's not how most AI companies work. It's how we do.

Our work

3 steps to a system that runs itself.

  1. Discover: We learn your business and map the right stack (Go Mammoth, MammothIQ, add-ons).
  2. Build: Your system is configured, tested, and fully set up. You don't touch a thing.
  3. Launch: We hand you the keys and stick around. The system compounds. You get back to building.

About · the human behind the mammoth

Jack Fentress, founder of Jolly Mammoth

I watched AI take the gigs I used to win. So I learned to build with it.

Jack Fentress Founder & AIBMM Executive Coach

I started out as a freelance marketer and copywriter. Brand guides, landing pages, lead magnets, campaigns, etc. Mostly for sustainability and ESG companies, back in 2021. Then one day I opened ChatGPT for the first time, typed a prompt, and watched it do a version of my job in about four seconds. I'm not going to lie to you: that was a weird afternoon.

I could've dug in, fought it, and resisted the AI movement. Instead I got curious. And the deeper I went, the more familiar it felt. Reverse-engineering, workflows, big-picture vision, and efficiency applications. All skills I had already developed. The difference? Better tools. Same thinking.

So while everyone was bracing for AI to end the world, I started learning to drive it. And I found the gap: businesses need someone who gets how their operations actually run, then builds the systems that help their growth compound.

That's Jolly Mammoth. We advise and build, starting with your business, not the tech. HQ'd in Eau Claire, working with contractors and service businesses across Wisconsin. If you're nervous about what AI means for your company, I get it. I was on the wrong end of it years ago. Today, my goal is to help business owners feel confident to take on the shifting business landscape.
