Dimension Announces Profitable Growth and $1.65M Strategic Seed to Scale Seller OS, Its Agentic Operating System for Social Commerce
LOS ANGELES--(BUSINESS WIRE)--Jul 29, 2026--
Dimension, the social commerce tech company building Seller OS, an agentic AI operating system that replaces TikTok Shop’s native Seller Center, announced today that it has raised $1.65 million in seed funding. The round includes participation from Science Inc., UpscaleX, OpenSky, Long Run Capital, 1864 Fund, Lawrence Hsu and creator-investor Austin Sprinz. The funding accelerates Seller OS’s move from private beta to general availability for the agencies and brands that run social commerce.
Dimension operated profitably in 2024 and 2025, building Seller OS out of its own margins before this funding round. The company has managed and scaled TikTok Shop operations for more than 40 brands and agencies, including Final Boss Sour, Bones Coffee and Leilo, optimizing storefront operations, affiliate programs, paid advertising and customer acquisition. That operating work produced the workflows Seller OS now automates.
“Raising more money was never the goal,” said Ali Mirzaei, Founder and CEO of Dimension. “We were profitable within our first months and have generated more revenue than we’ve raised. We chose investors based on the relationships, expertise and strategic value they can bring to the table as we build the infrastructure layer for social commerce.”
Mirzaei was among the earliest sellers on TikTok Shop following its U.S. launch in 2023 and within six months built the #1 shop on the platform. That experience informed the creation of Dimension’s Seller OS, an agentic AI operating system designed to replace TikTok Shop’s native Seller Center with a comprehensive command center for social commerce operators. The platform automates shop operations, affiliate and creator management, advertising and customer support in a single system. For agencies and operators, Seller OS can reduce workload by up to 90 percent. Since entering private beta this spring, weekly active usage has more than tripled, agencies have begun onboarding their client shops onto the platform, recent signup cohorts are holding 92 percent retention into week three, and shops running on Seller OS transact more than $3.2 million per month in gross merchandise value.
“Dimension has become a secret weapon within the Science portfolio ecosystem,” said Michael Jones, Co-Founder and CEO of Science Inc., Former CEO of MySpace. “Ali and his team have repeatedly proven their ability to quickly scale brands on TikTok Shop, combining strong execution with a deep understanding of how social commerce works. They’ve become a trusted operating partner for our portfolio companies, and we’re excited to support them as they build the leading infrastructure platform for social commerce.”
Dimension’s operating expertise has translated into measurable results across its portfolio.
- To date, Dimension has helped four brands reach the #1 position in their categories on TikTok Shop, including Science portfolio company Final Boss Sour, which Dimension helped to scale more than 20x on TikTok Shop to become one of the platform’s leading brands.
- Dimension estimates it has driven more than $100 million in gross merchandise value, helped brands secure tens of millions of dollars in funding and supported expansion into thousands of retail locations.
- For every dollar generated on TikTok Shop, Dimension estimates its brands see an additional two to three dollars in revenue across Amazon and direct-to-consumer channels, underscoring the platform’s growing influence on broader retail performance.
“The opportunity in front of Dimension is significant because the social commerce market is being defined right now,” said Alan Zong, Co-founder and Partner of UpscaleX and former Head of Innovation Investment at Alibaba International. “We’re at a point where consumer adoption is accelerating rapidly, but the infrastructure supporting brands and agencies is still being built. The companies that establish themselves as foundational platforms during this phase have the potential to shape the ecosystem for years to come.”
Dimension will use the funding to expand its engineering team, accelerate product development, grow its go-to-market efforts and bring Seller OS to general availability for agencies and brands.
