Tom Evslin played a pivotal role in the early days of the internet, bridging the gap between legacy corporate networks and the connected world we know today. During his time at Microsoft in the early 1990s, Evslin functioned as an internal advocate for internet integration at a time when leadership focused heavily on proprietary competition like Lotus Notes. While Bill Gates initially prioritized established product roadmaps for Exchange and Office over internet protocols, internal pressure and rising demand eventually shifted the trajectory. Evslin managed gateways that connected early mail systems to the internet, proving that users and engineers were already bypassing corporate restrictions to communicate via SMTP.
After his stint at Microsoft, Evslin moved to AT&T to help shape their internet strategy. At that point, the company lacked a clear path forward. He advocated for AT&T to act as an internet service provider and pushed for flat-rate, all-you-can-eat pricing models. Despite significant internal skepticism regarding development timelines, he successfully helped launch WorldNet. This service provided internet access to a mass audience, though it quickly faced massive demand that tested infrastructure limits.
Evslin eventually turned his attention to voice over IP. When the concept proved too difficult to implement within the structure of AT&T, he left to found his own wholesale carrier, ITXC, in 1997. His career highlights the friction that existed when traditional telecommunications giants encountered the rapid expansion of the internet. By prioritizing speed and connectivity, Evslin helped bring essential communication tools to both enterprise users and the general public during a decade of rapid technological shift.
