Josh's story
Josh started his career in marketing in 2018, building ad campaigns from the ground up and shaping every step of the customer journey. He watched leads turn from curious visitors into five-star reviews, and learned what moves people along the way.
That work pulled him into product development: product launches, custom brand strategies, company vision, and AI chatbots that hold conversations over SMS, email, Messenger, Instagram DM, and Google Maps chat.
He went on to run companies himself, as President of Noteable Music Academy and as Chief Operations Officer of Big Little Gyms, which made the Inc. 5000 list of fastest-growing private companies in 2024 and 2025. Along the way he found that his favorite thing to build is a team. Today he brings all of it to LetLois, where he is founder, COO, and CMO alongside Noah.
What Josh brings to the table
It's easier to teach a skill to someone who's easy to work with than to teach a skilled person to be easy to work with. Josh brings both.
Campaigns built from the ground up, a customer journey designed step by step, and frequent reporting, so everyone can see what is working. Not every campaign wins on day one; sometimes the late bloomers are the best.

Josh is an absolute treasure to have on any team. Not only did he make work exciting and dynamic with his charisma and attitude but he inspired us all to grow and be better versions of ourselves every day.
Noah RanceIt was nice to work with Josh. He's a good communicator and always took ownership for his actions. He'll talk your ear off about music but you'll have fun with him on your team.
