Today, I have the pleasure of once again speaking with Prashanth Chandrasekar, the Chief Executive Officer of Stack Overflow—a name that resonates with nearly every professional or aspiring software developer around the world. The last time Prashanth joined this show was back in 2022, an almost prophetic moment, occurring just a month before OpenAI’s ChatGPT propelled artificial intelligence into a new cultural and technological epoch. The arrival of generative AI profoundly disrupted not only how people interact with technology, but also the very foundation of companies like Stack Overflow. Practically overnight, the site was forced to reconsider its identity and future relevance.
For anyone unfamiliar, Stack Overflow is far more than a simple forum; it is the canonical question‑and‑answer platform where programmers, engineers, and technologists collaborate to solve intricate problems in software development. Before the advent of advanced language models, it functioned as a self‑sustaining ecosystem—developers posed challenging technical questions, other members of the community responded, and together they refined solutions that often became industry references. However, the introduction of tools such as ChatGPT drastically altered that equilibrium. Artificial intelligence demonstrated an uncanny ability to generate code, to refactor programming logic, and even to construct entire functional applications from mere prompts. Meanwhile, Stack Overflow’s once‑trusted forums became inundated with automatically generated answers—many inaccurate, many repetitive—which eroded the overall credibility of the site’s knowledge base and threatened its cultural stature.
As you will hear from Prashanth himself, the transformative potential of ChatGPT was readily apparent to him almost from the moment of its release. In a decisive response, he convened what could only be described as a company‑wide emergency session. Roughly ten percent of Stack Overflow’s workforce—about forty employees—was reassigned to focus exclusively on crafting an adaptive strategy that might safeguard the company’s relevance. That urgent pivot would shape not only internal structures but also Stack Overflow’s business model for the years to follow.
Now, three years later, the organization finds itself redefined and refocused. It has evolved primarily into an enterprise‑oriented software‑as‑a‑service company, offering bespoke knowledge‑management and AI‑enhanced tools for some of the world’s largest corporations. Stack Overflow has also developed a significant data‑licensing operation, providing vetted and richly contextualized developer data to major AI research laboratories and technology firms seeking to train or fine‑tune their language models.
This shift marks a radical transformation from Stack Overflow’s original identity as the open community where anyone could freely seek coding assistance. That naturally raises a pressing question: in a world where generative AI can instantly answer programming queries, does Stack Overflow still attract new developers in 2025? According to Prashanth, the answer is an emphatic yes. While automated systems are proficient at resolving simple and routine tasks, the genuinely complex, nuanced programming challenges still demand expert human interpretation and dialogue—precisely the environment Stack Overflow continues to cultivate.
Throughout the conversation, one statistic stands out for its significance. Prashanth notes that more than eighty percent of Stack Overflow users either regularly employ or intend to employ AI tools in their development work. Yet, of that same population, barely twenty‑nine percent express genuine trust in AI’s competence. This sharp divergence speaks volumes about our present moment: artificial intelligence is ubiquitous and widely utilized, yet skepticism about its reliability and implications remains extraordinarily high. That paradox echoes across countless domains, from social media commentary to corporate technology adoption. On one hand, individuals vocally criticize AI systems for inaccuracies, biases, or ethical risks; on the other, they continue to depend on them as integral parts of their workflows.
Prashanth, however, does not shy away from engaging with this contradiction. He offers thoughtful reflections on the uneasy coexistence of human judgment and machine generation, as well as the delicate balance required to sustain a community predicated upon human expertise while embracing automation. Listeners will likely find his insights both candid and intellectually stimulating.
In the interview portion that follows, Prashanth recounts in detail how the company confronted its so‑called ‘code red’ moment. He describes the internal deliberations, the strategic reorganization, and the decision to dedicate a specialized cross‑functional team to developing an immediate response. The initiative drew heavily on his prior experience in navigating market disruption—particularly his earlier tenure at Rackspace, where he had helped steer the company through the early turbulence of the cloud‑computing revolution. He also cites the influence of the late business theorist Clayton Christensen, whose seminal concept of ‘The Innovator’s Dilemma’ informed his approach: when faced with an existential technological shift, the most effective response often requires establishing a semi‑autonomous team insulated from legacy assumptions and empowered to experiment freely.
Under his leadership, Stack Overflow implemented such a model, dividing its efforts between the preservation of its cornerstone public forum and the expansion of its enterprise solutions. The company’s thriving private‑instance platform—used internally by organizations to manage proprietary knowledge—has become an increasingly vital resource in the age of AI, supplying the contextual data that large language models require to operate intelligently within corporate environments.
Prashanth elaborates that communication with employees during that turbulent period was constant and transparent. Instead of issuing a single dramatic proclamation, he conveyed the gravity of the situation through a series of weekly memos detailing his thinking, the company’s goals, and praise for exemplary work. Over the course of several months, these incremental communications culminated in a unified mission for adaptation and reinvention.
From there, the conversation turns toward the ongoing challenges of moderating AI‑generated content. Shortly after ChatGPT’s debut, Stack Overflow witnessed an unprecedented influx of automatically produced answers. Community moderators rapidly identified the pattern, recognizing that many of these submissions were superficial, misleading, or outright incorrect. Acting swiftly, Stack Overflow instituted a formal ban on AI‑generated answers, reaffirming its commitment to being a ‘trusted and vital source for technologists.’ Maintaining that trust, Prashanth explains, became a central pillar of the company’s vision.
Even as it restricted AI content from public postings, Stack Overflow’s engineering teams began to integrate AI capabilities more thoughtfully behind the scenes. The recently introduced ‘AI Assist’ feature—an interactive conversational tool grounded in the company’s vast store of verified questions and solutions—embodies this integration. Users can engage with AI Assist using natural language, receiving context‑aware guidance drawn from human‑curated material before any external language model is consulted. In this way, the system blends automation with human‑safeguarded reliability.
Prashanth goes on to delineate Stack Overflow’s contemporary revenue streams. The largest portion derives from its enterprise SaaS product, now adopted by over twenty‑five thousand corporations worldwide. These clients deploy private Stack Overflow networks to enhance knowledge sharing and technical collaboration within their internal teams. The second major source of income comes from data licensing agreements with major technology entities—OpenAI, Google, Databricks, and others—who lawfully access Stack Overflow’s dataset for large‑model training and related tasks. A smaller but still notable share of revenue continues to stem from advertising directed toward the platform’s valuable developer demographic.
When pressed on whether new users still join Stack Overflow in the current, AI‑saturated environment, Prashanth points out that the site remains highly active, albeit with a shift in the complexity of questions. The simpler requests that language models can easily address have noticeably declined, while more advanced, intricate discussions persist and even grow. To attract and retain participants, Stack Overflow has diversified its community experience—introducing interactive chatrooms, technical challenges akin to digital hackathons, and partnerships such as its collaboration with Indeed to better connect developers with employment opportunities. These initiatives reflect the platform’s broader mission to ‘cultivate community, power learning, and unlock growth.’
Yet, this evolution has not been without friction. Moderators and long‑time contributors have expressed discomfort with AI partnerships and licensing arrangements, fearing that their volunteer labor may be exploited for corporate profit without sufficient reciprocity. Prashanth acknowledges this tension candidly, noting that Stack Overflow’s roots lie in altruism and knowledge sharing rather than monetary reward. Nonetheless, he argues that adapting to the new internet economy—where traditional ad revenue and web traffic patterns have been destabilized by AI search paradigms—is imperative for survival. Licensing agreements, he maintains, enable continued investment in the very community features that users cherish.
He also describes how Stack Overflow quickly implemented anti‑scraping technologies to prevent unauthorized data extraction by AI companies. While some firms approached negotiations cooperatively—OpenAI and Google, for example—others remained evasive, prompting ongoing dialogue across the industry about ethical data usage and the boundaries between public information and proprietary value.
Structurally, Stack Overflow has streamlined into two major divisions: one dedicated to serving the enterprise market and another to managing the global developer community, which also houses the data‑licensing operation. Currently, the company employs roughly three hundred people worldwide and, despite past contractions, operates profitably. Its resources are now directed toward what Prashanth calls the ‘knowledge intelligence layer’—an infrastructure that supports both internal corporate insight and trustworthy integration with AI agents.
As the conversation approaches its conclusion, Prashanth identifies 2026 as what he calls ‘the year of rationalization’ for artificial intelligence. After the exuberance of the initial adoption phase, he predicts that businesses will increasingly demand measurable return on investment, compelling a wave of consolidation among vendors and prompting companies to reassess which AI tools genuinely enhance productivity. In this landscape, Stack Overflow positions itself not as a competitor to generative models but as the indispensable trust and data layer underpinning them.
When asked about his personal approach to leadership and decision‑making, Prashanth emphasizes proximity to the front lines. He believes executive directives lose clarity when filtered through too many intermediaries; thus, he frequently interacts directly with both customers and community participants. That practice, he says, guided the decision to implement AI Assist—an initiative that might have seemed counterintuitive given public skepticism but which accurately reflected the overwhelming preference among users for conversational, natural‑language interfaces.
Ultimately, Prashanth closes the discussion by reiterating his optimism. Despite the turbulence, Stack Overflow’s twin mission—supporting developers as a public community and empowering enterprises through intelligent knowledge systems—remains firmly intact. The company’s core asset has always been human expertise, and its continued relevance depends on its ability to integrate that expertise with the evolving capabilities of artificial intelligence. As new tools emerge and the industry matures, Stack Overflow aims to stand not merely as a relic of the pre‑AI internet, but as the connective, trustworthy fabric linking developers, information, and intelligent systems across the digital world.
