Tiide’s founder-led team joins Simplistic following an existing cross-sell partnership between the two companies
DENVER, CO, UNITED STATES, September 24, 2026 /EINPresswire.com/ — Simplistic, LLC, an Agentic Commerce Consultancy, Shopify Plus Platinum Partner, and Rallyday Partners portfolio company, today announced it has acquired Tiide Commerce, a fast-growing Amazon and TikTok Shop growth agency founded and led by Mark Lathrum. The deal closed September 21, 2026, adding dedicated marketplace management expertise to Simplistic’s service lines.
Simplistic and Tiide already know each other well: Tiide has served brands cross-sold from Simplistic’s Flash Site engagements, and its boutique, founder-led, hands-on approach reflects the same entrepreneurial culture Simplistic was built on.
“Joining Simplistic means our clients keep the hands-on service they know, while gaining the scale and resources of a larger team,” said Mark Lathrum, founder of Tiide Commerce.
“Amazon and TikTok Shop are a natural extension of where we’ve been investing, and Tiide gets us there with a team we already know and trust from successful work together,” said Scott Webb, CEO of Simplistic.
Tiide marks Simplistic’s first acquisition since Rallyday Partners’ investment in the company, building on the same growth strategy that produced last year’s acquisition of Sidekick Agency and its expanded lifecycle marketing capabilities.
“Part of why we invested in Simplistic was the roadmap Scott and his team had already mapped out for building a broader marketplace platform”, said Rallyday Co-Founder & Managing Partner Nancy Phillips. “Partnering with Tiide is a natural first step of that strategy and we’re excited to have Mark and his people join the team.”
Financial terms of the transaction were not disclosed.
