ShareASale

In 2000, 25-year-old developer Brian Littleton identified a gap in the affiliate marketing space and built ShareASale as a side project. He saw the business model was inherently cash-positive and, crucially, he had the technical skills to build the platform himself. This combination of a profitable business model and technical capability meant he didn't need to raise external capital—ShareASale was bootstrapped from day one.

Littleton built the entire platform solo initially, though he acknowledges "that was a mess." His developer background gave him a significant advantage: he could code the infrastructure that tracked clicks, sales, and commissions between publishers and merchants. The core value proposition was simple but powerful—sit in the middle between content creators (bloggers, podcasters, website owners) and retailers, track affiliate commissions, and take a 20% cut of the commission paid out.

By the end of year one to year and a half, ShareASale had recruited about 500 retailers—mostly small businesses. This growth surprised even Littleton. The marketplace succeeded because of its two-sided liquidity strategy: about 20% of publishers found programs directly from retailers (like visiting The RealReal's website), another 20% came through ShareASale's network marketplace, and retailers brought in their own partners. This natural network effect snowballed growth organically.

The company found its niche in fashion and retail goods early on, building deep expertise and relationships in that vertical. By focusing on physical products rather than digital ones (unlike competitor Clickbank), ShareASale carved out a defensible position against competitors like Commission Junction and Rakuten. The bootstrapped, cash-positive model meant Littleton could grow methodically without pressure from investors. He held 100% equity through the entire 17-year journey, though he did use bonuses to incentivize and retain talent.

By 2017, ShareASale had grown to over 5,200 retailers on the platform and over a million publisher accounts, of which approximately 20,000 had earned commissions in the past 12 months. The company reported $14M in annual revenue with anticipated EBITDA of around $5.8M in 2016. In January 2017, Littleton sold ShareASale to Awin (the merged entity of Affiliate Window and Zanox), a global affiliate marketing network dominator. Littleton stayed on as the team grew, driven by the opportunity to expand internationally and provide growth opportunities for his 30-person Chicago team, many of whom had been with the company for over a decade.
