Simplistic, a Denver-based agentic commerce consultancy and Shopify Plus Platinum Partner, has acquired Tiide Commerce, an Amazon and TikTok Shop growth agency, expanding its capabilities in marketplace management and digital commerce. The transaction closed on September 21, 2026, and represents Simplistic’s first acquisition since receiving an investment from private equity firm Rallyday Partners.
Founded and led by Mark Lathrum, Tiide Commerce helps brands grow their businesses across Amazon and TikTok Shop through marketplace strategy, management, and hands-on client support. The acquisition adds specialized marketplace expertise to Simplistic’s existing services, which include Shopify development, lifecycle marketing, conversion rate optimization, and AI-enabled managed services.
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 and giving the companies experience working together.
Simplistic intends to use the combination to provide brands with a more integrated approach to digital commerce, connecting their direct-to-consumer websites with major third-party marketplaces.
For businesses selling across multiple digital channels, maintaining consistent branding, coordinating marketing campaigns, and managing customer relationships can require different technology platforms and specialized teams. By adding Tiide’s expertise, Simplistic is expanding its ability to support those activities within a broader digital commerce services offering.
The acquisition is particularly relevant to brands seeking to develop their presence on Amazon and TikTok Shop while maintaining and optimizing their existing Shopify storefronts.
Tiide brings more than 20 years of combined team experience across over 15 product categories. Its founder-led operating model emphasizes direct client relationships and customized marketplace growth strategies.
Following the transaction, Tiide’s team will join Simplistic, giving its existing clients access to additional technology, marketing, and operational resources.
The combination also provides Simplistic with an opportunity to offer marketplace management services to its established customer base, including brands that have previously engaged the company for website development and other commerce-related projects.
Simplistic’s broader strategy involves building a platform that combines technology development, marketing, marketplace operations, and AI-enabled services to support mid-market and enterprise brands.
The company describes itself as an agentic commerce consultancy, reflecting its focus on integrating artificial intelligence and automation into digital commerce operations.
As brands expand across direct-to-consumer websites, online marketplaces, and social commerce platforms, Simplistic is developing a broader range of services intended to support those channels.
The transaction follows Simplistic’s 2025 acquisition of Sidekick Agency, which expanded its lifecycle marketing capabilities. Together, the acquisitions extend the company’s services into additional areas of digital commerce, including customer engagement and third-party marketplace growth.
Tiide is the first acquisition completed under Simplistic’s partnership with Rallyday Partners. The investment firm is supporting a growth strategy focused on expanding Simplistic’s service offerings and capabilities through a combination of organic development and strategic acquisitions.
For Rallyday, the addition of Tiide represents an initial step in executing the broader acquisition strategy Simplistic’s management team had developed before the private equity investment.
Simplistic was founded in 2014 and currently employs more than 100 professionals across the United States and Argentina.
The company is one of 10 partners in Shopify’s Large Accounts program, providing services to mid-market and enterprise businesses seeking to develop and optimize their digital commerce operations.
Its Shopify Plus Platinum Partner status and existing marketing capabilities provide a foundation for extending services into additional marketplace channels.
The Tiide acquisition adds dedicated Amazon and TikTok Shop expertise while preserving the client-focused operating approach that the two companies had established through their previous collaboration.
The combined organization plans to build on those relationships as Simplistic continues expanding its commerce platform and services for brands operating across multiple digital channels.
