About Social Mulli

Started by a former owner who got tired of being lied to.

Social Mulli is the marketing agency built for gym owners, fitness studios, and local wellness businesses that are done being promised the world and handed a slide deck.

The founder story

She lived through it before she built the fix.

Social Mulli was started by Danelle, a former Anytime Fitness owner who spent years getting pitched by marketing agencies promising to fill her gym in 30 days or her money back.

What she actually got was silence after the contract signed. No results. No updates. Just the same frustration every gym owner knows too well.

Here is the thing that drove the whole idea for Social Mulli:

Gym owners would never believe “lose 50 pounds in 30 days.” But they will fall for “fill your gym in 30 days” every time.

Same lie. Different industry.

Social Mulli exists to be the marketing partner that treats gym and wellness owners the way a good trainer treats their clients. Honestly. Consistently. In your corner for the long haul.

The core belief

Marketing is not a magic pill. Neither is weight loss.

Both work the same way. Trial. Error. Consistency. Someone in your corner telling you to keep going when it feels like nothing is happening.

That is what the REPS Method is. That is what Social Mulli is.

Who you actually work with

Two people. Both answer their phones.

No account managers, no offshored strategy, no handoff after the sale. When you work with Social Mulli, you work with us.
