Early career
In 1985, Kaufer co-founded CenterLine Software, a company that developed programming and testing tools for software developers.

The remaining assets became CenterLine Development Systems, which was headed by his wife, Caroline Kaufer.TripAdvisor
In 1998, while planning a vacation, Kaufer struggled to find unbiased information and candid opinions about specific hotels. Caroline suggested that he build a website to help other travelers, but he did not act on the idea for over a year.He launched the site a few years later. Initially, the company followed a business-to-business model, partnering with other travel-related websites rather than engaging directly with travelers. Kaufer later adopted a consumer-focused model, making TripAdvisor publicly accessible, aggregating information on hotels and attractions, encouraging user reviews, and structuring contracts that generated revenue through referral fees from travel companies.
As the company expanded, Kaufer remained in leadership roles, declining a proposed sale to Yahoo and later overseeing TripAdvisor through a $210 million sale to IAC/InterActiveCorp in 2011. As of 2022, the site attracted more than 400 million visitors per month. In 2022, Kaufer stepped down after 22 years as TripAdvisor's CEO.

Kaufer's wife died from pancreatic neuroendocrine cancer in 2005 at age 42, leaving Kaufer with four children, then aged 13, 12, 7, and 5. In 2012, he remarried a woman with four kids of her own.Through the Stephen and Caroline Kaufer Fund for Neuroendocrine Research, and through contributions to the Caring for Carcinoid Foundation, Kaufer has supported medical research related to his wife's illness.
Kaufer has been a longtime critic of Google for what he has described as its "dominance in Internet gatekeeping".
