Life After the CEO Chair: Joel Spolsky's Sabbatical and New Ventures

A New Chapter: From CEO to Chairman

Joel Spolsky, the co-founder and former CEO of Stack Overflow, has stepped into a new phase of his career—one he describes as a sabbatical rather than retirement. With Prashanth Chandrasekar now at the helm as CEO, Joel has handed over the day-to-day leadership but remains active as chairman. He still joins customer calls and holds weekly meetings with Prashanth, but the reduced responsibilities have given him a fresh perspective. Watching Prashanth reorganize the company has been enlightening; Joel admits that realizing how much he didn’t know about running a medium-sized business is oddly satisfying. In fact, he considers it the best possible outcome if Prashanth proves to be a more effective CEO by driving the company to new heights.

Living in Manhattan’s “Naturally Occurring Retirement Community” (NORC), Joel is keen to emphasize that this period is not full retirement. Far from winding down, he is busier than ever. To answer the frequent question “What are you doing now?” he offers an update on his activities and the ventures he chairs.

The Companies Under My Chairmanship

Joel serves as chairman of three distinct companies, each addressing different niches in technology. Here’s a closer look at each, with internal links to jump between sections: Stack Overflow, Glitch, and HASH.

Stack Overflow: A Trusted Handover

Stack Overflow remains a central part of Joel’s professional life, albeit from the sidelines. As chairman, he provides guidance while Prashanth leads the operational strategy. This transition has been smooth, and Joel takes pride in seeing the company evolve under new management.

Glitch: Empowering the Web Builder

Fog Creek Software, which Joel co-founded, has been rebranded as Glitch, a platform described as “the friendly community for building the web.” Under CEO Anil Dash, Glitch has grown to host millions of apps and secured substantial funding to accelerate expansion. Joel believes that every era needs a simplified programming environment for the majority of developers who don’t require complex features like Git branches or multi-step deployment. These developers simply want to write code and see it run, and Glitch caters precisely to that need.

HASH: Simulating Complex Systems

The third company, HASH, operates a bit under the radar but recently published extensive details on its website. HASH is building an open-source platform for agent-based simulations—a powerful tool for modeling problems where individual behaviors are known but aggregate outcomes are not. For instance, a city planner could simulate traffic to justify a new bus line. Instead of assuming each bus removes 50 cars, the model simulates each commuter’s decision-making process based on time and cost savings. By running thousands or millions of potential bus routes, planners can identify which ones actually reduce congestion. This approach works even when closed-form formulas are unavailable, making it applicable to various domains.

Life in the City and Beyond

Between board meetings and advisory roles, Joel finds time for personal pursuits. He lives with his family in Manhattan’s NORC and shares his home with Cooper, his two-year-old dog. If any web app is in need of a mascot, Cooper is available (apply within).

Joel’s schedule is packed, but he relishes the flexibility his new role affords. By stepping back from day-to-day operations, he can focus on big-picture strategy for the companies he chairs while exploring new interests. This sabbatical, as he calls it, is proving to be a productive and fulfilling chapter—one that allows him to support others in leading while enjoying the fruits of his past labors.
