From Startup to a Global Market Leader

Executive Summary 

The e-commerce advertising industry generates $800 billion a year, and winning share of it depends on how fast and precisely a brand can compete on Amazon, Walmart and alike. Flywheel Digital grew from a two-person startup founded in 2014 into a company of more than 2,000 people operating inside that market, managing over 100,000 advertising campaigns and millions of bid operations a day for consumer brands selling on Amazon and other major digital retailers. Flywheel’s founders had a strong go-to-market idea but no technology to run it at scale: onboarding was manual, and there was no platform to absorb the volume a fast-growing client base would generate. SSI became Flywheel’s technology partner from the earliest stage, building the custom platform, data infrastructure, and algorithmic advertising engine that let Flywheel onboard clients quickly and scale without rebuilding its foundation. That platform became the infrastructure both of Flywheel’s acquirers bought into. Ascential acquired Flywheel for up to $400 million in 2018, and five years later Omnicom acquired it for $835 million, a combined $1.235 billion across two exits. SSI has remained Flywheel’s technology partner throughout, including after both acquisitions.

 

Client Background 

A Two-Person Startup Built into a Global Digital Commerce Company 

Flywheel Digital was founded in 2014 to help consumer brands succeed on Amazon. What began as a five-person operation grew into a company of more than 2,000 people, operating inside the $800 billion e-commerce advertising industry. Flywheel’s business spanned every layer of digital commerce a brand needs to compete on Amazon and other marketplaces: media, retail operations, and finance. 

Quite soon Flywheel became one of the largest managed-services providers to consumer product companies selling on Amazon. By the time of its first acquisition in 2018, Flywheel served more than 70 customers with a team of more than 90 staff based in Baltimore and Seattle, according to Ascential’s own acquisition announcement. 

The Business Needs 

A Strong Business Idea Outgrowing Its Own Infrastructure 

Flywheel’s founders identified a real opportunity: brands needed help competing on Amazon, and few providers combined media, retail, and finance expertise the way Flywheel could. What Flywheel did not have was the technology to run that business at scale. Client onboarding was manual, and there was no platform to manage the volume of advertising campaigns, bid operations, and marketplace data a fast-growing client base would generate. Every campaign insight required a manual download and spreadsheet sort, so data arrived hours after it was current, an unworkable lag in a market where competitive position changes by the hour. No formal advertising API existed yet for Flywheel’s primary retail channel, so building any platform at all meant engineering the entire data collection layer from scratch. 

Every new client added work instead of building on a repeatable system, and the business risked being outrun by its own growth. Flywheel needed a technology partner to build the enablement layer under a business model that had already worked. 

Solution Blueprint & Implementation 

Building the Platform Underneath the Business 

SSI joined Flywheel at the earliest stage and built a custom platform that automated client onboarding and let the business scale without re-architecting each time it grew. As Flywheel’s client base and data volume expanded, SSI built out: 

• A cloud-native, AWS-based architecture, with load-balanced, auto-scaling microservices behind a CloudFront-served frontend, capable of absorbing exponential growth in clients and data without manual intervention. 

• An algorithmic propagation platform that manages more than 100,000 campaigns and executes millions of bid operations daily across Flywheel’s retail media business. 

• Built enterprise business intelligence into the platform, arming executives with the data behind every million-dollar decision. 

• Data infrastructure that pulls and processes terabytes of marketplace data every day, feeding the reporting and insight layer Flywheel’s clients rely on. 

• A High Performing team model designed to accelerate delivery velocity, which Flywheel continues to use today. 

SSI’s team grew alongside Flywheel’s, from five engineers to more than 70 at its peak, eventually serving as Flywheel’s core technology team of more than 60 dedicated engineers across product, platform, and data. That team built early integrations with top retailers, establishing Flywheel as a preferred partner, and, later, the platform onto which Ascential consolidated its other digital commerce brands. 

The Impact 

What Changed for Flywheel 

• Business Scale. Flywheel absorbed 2,000% growth in its client base in its first four years without rebuilding its platform, scaling from a five-person operation to a company of more than 2,000 people on the technology foundation SSI built at the outset. 

• Platform Modernization. A manual, spreadsheet-run operation became a cloud-native advertising platform that automates client onboarding and manages more than 100,000 campaigns and millions of bid operations a day, evolving from a startup tool into infrastructure built to acquisition-grade standards. 

• Engineering Capability. SSI’s dedicated team grew from five engineers to more than 70 at its peak, giving Flywheel a 60-plus person technology organization with deep product, platform, and data expertise in place of a project-based vendor relationship. SSI also trained Flywheel’s engineers, embedding platform knowledge directly into the client’s own team. 

• Precision and Cost Efficiency. The algorithmic propagation platform prices and routes decisions no manual team could match at that volume, and the same infrastructure scaled with client growth instead of requiring proportional increases in headcount or spend.  

• Competitive Differentiation. Early integrations with top retailers made Flywheel a preferred partner, and SSI made Flywheel the technology leader within Ascential, driving the growth that led Ascential to consolidate all its other digital commerce brands under the Flywheel platform. 

• M&A Value Creation. The platform SSI built became the infrastructure serious enough for two acquirers to buy. Ascential acquired Flywheel for up to $400 million in 2018, and five years later Omnicom acquired it for $835 million, a combined $1.235 billion across two exits. 

• Continuity and Trust. SSI has remained Flywheel’s technology partner for 11 years, through its growth, its acquisition by Ascential, and its acquisition by Omnicom, with the High Performing team model SSI introduced still active today. 

• Capital Efficiency. The platform investment reduced ongoing operating costs, extending platform longevity, and lowering total cost of ownership over time. 

• Platform Longevity. The platform has operated for 11 years without a full rebuild, preserving speed to market new capabilities. 

• Cost Avoidance. The platform’s invoice tracking eliminated $100 million in revenue leakage, recovering funds that would otherwise have been absorbed as an operating loss.
