Ryan and Gillian Carson founded Treehouse in 2011, a project that emerged from Carson's previous company, Carsonified, and its video-tutorial service Think Vitamin Membership.^[5] Carson redesigned and rebranded the service as Treehouse because the name "reflects the wonder of learning as a child."^[6][7] In 2011, Treehouse opened their first office in Orlando, Florida, In 2012 they opened their second office and moved Treehouse HQ to Portland, Oregon.^[8]

Carson has faced criticism in the past from employees and community members accusing him, a white man, of profiting off DEI efforts and of blocking individuals on social media who have questioned his motives, including prominent diversity advocate Stephen Green.^[16]

In September 2021, Carson drew the ire of Treehouse students and community partners by laying off 90% of Treehouse's staff without severance pay via a five-sentence message to Slack, despite expanding the company over the first half of 2021 and launching new initiatives such as the Ubora scholarship program. Employees who remained were told Treehouse would no longer cover their health insurance.^[17][18]

In December, 2021 Treehouse was acquired by Xenon Partners, an owner/operator of enterprise SaaS businesses. Founder Ryan Carson departed the company in conjunction with the acquisition, with Jason Gilmore assuming the role of CEO.
