Simplistic has acquired Tiide Commerce, an Amazon and TikTok Shop growth agency. The transaction closed on September 21, 2026. The amount was not disclosed in the sources.
Simplistic is a Denver-based agentic commerce consultancy and Shopify Plus Platinum Partner. The company said the acquisition expands its capabilities in marketplace management and digital commerce, adding specialized marketplace expertise to services that include Shopify development, lifecycle marketing, conversion rate optimization, and AI-enabled managed services.
Tiide Commerce was founded and led by Mark Lathrum and helps brands grow across Amazon and TikTok Shop through marketplace strategy, management, and hands-on client support. The source states Tiide brings more than 20 years of combined team experience across over 15 product categories, with a founder-led operating model emphasizing direct client relationships and customized marketplace growth strategies. Following the transaction, Tiide's team will join Simplistic.
The transaction builds on an established relationship between the two companies. Before the acquisition, Tiide provided services to brands referred through Simplistic's Flash Site engagements, creating an existing commercial partnership.
Simplistic said it intends to use the combination to provide brands with a more integrated approach to digital commerce, connecting direct-to-consumer websites with major third-party marketplaces. The company said the acquisition is particularly relevant to brands seeking to develop their presence on Amazon and TikTok Shop while maintaining and optimizing existing Shopify storefronts.
The acquisition is Simplistic's first since receiving an investment from private equity firm Rallyday Partners, and the first completed under that partnership. It follows Simplistic's 2025 acquisition of Sidekick Agency, which expanded its lifecycle marketing capabilities.
"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.
"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.
"Part of why we invested in Simplistic was the roadmap Scott and his team had already mapped out for building a broader marketplace platform. Partnering with Tiide is a natural first step of that strategy and we're excited to have Mark and his people join the team," said Nancy Phillips, co-founder and managing partner of Rallyday Partners.
Simplistic was founded in 2014 and employs more than 100 professionals across the United States and Argentina, according to the source.
