Stewart Butterfield - We Don’t Sell Saddles Here - [Founder’s Field Guide, EP. 43]

My guest today is Stewart Butterfield, founder and CEO of Slack. Stewart’s 2014 essay “Why We Don’t Sell Saddles Here” had a massive impact on my own business journey, which made this discussion extra special.

Episode Summary

Executive Summary: Patrick O'Shaughnessy interviews Stuart Butterfield about Slack's origin, product philosophy, and leadership. The conversation centers on owner's delusion, selling behavioral change rather than features, the power of constraints, and why communication quality determines organizational performance.

Main Topics: Owner's Delusion and Marketing (Priority: 10/5): Founders overestimate how much outsiders care or understand their product. Innovation as Behavior Change (Priority: 10/5): Real innovation is changing how people work, not just shipping software. Constraints and Creativity (Priority: 8/5): Limits sharpen design and help teams find the steep part of the value curve. Slack's Origin Story (Priority: 9/5): Slack emerged from IRC-based collaboration tools built while game projects failed. Communication as Core Work (Priority: 9/5): Executives spend most of their time on coordination, yet little training exists. Digital-First Work and Leadership (Priority: 8/5): Remote and hybrid work can improve productivity if communication norms evolve. Open Platforms and APIs (Priority: 7/5): Flickr and Slack gained value by letting users build integrations and ecosystems.

Key Arguments: Innovation = behavior change; Slack succeeds when teams communicate differently. Most users arrive with low intent, so products must translate into their terms. Marketing and product meet at the human attention boundary, not feature lists. Constraints help identify the steep utility curve and avoid wasteful feature bloat. Slack's channel model creates shared context email cannot match. Executives do mostly communication/coordination; improving it could unlock huge gains. Open APIs create long-term ecosystem value even if they reduce near-term control. Leaders often self-deceive by blaming people instead of redesigning incentives/system.

Data Points: Slack visibility vs email: 10% - Stuart says Slack can give a user about 10% organizational access versus a tiny slice via email. Email access in large orgs: one basis point - He contrasts email's fragmented visibility with Slack's broader shared context. Historical message scale: tens of millions or hundreds of millions or even billions - Used to describe the amount of prior organizational communication inaccessible to new hires in email. 5K contest limit: five kilobytes or less - The website competition Stuart launched in 1999 emphasized extreme design constraints. Internet access in 1999: 35% and 40% - Approximate share of U.S. households with internet access during the 5K contest era. Dial-up share: 95% plus - Most U.S. household internet access was still dial-up when the 5K contest began. Flickr API ecosystem: 2,000 apps - Stuart cites the number of apps in Flickr's app directory. Flickr customer integrations: 900,000 custom integrations - Customers built integrations themselves, showing the power of openness. Slack vendor base: 450 different vendors - Slack itself reportedly buys software from a large stack of vendors. Netsco enterprise cloud services average: 1,000 different cloud services - Used to illustrate software's continued expansion across enterprises. Company payroll example: $1 billion in payroll costs - Illustrates the scale of communication/coordination spend in a 10,000-employee firm. Communication effort share: 50%+ - Stuart estimates over half of knowledge-work effort is basic communication and coordination.

Pivotal Quotes: "sell the innovation, not the product" — Stuart Butterfield: Describing why people must understand the behavior change before they can value the tool. "the change in human behavior" — Stuart Butterfield: His definition of innovation as something that causes people to act differently. "the buck stops here" — Stuart Butterfield: On leadership accountability and avoiding blame through self-deception.

Implications: The open question is how organizations will redesign communication norms and work structures so digital tools produce measurable behavior change, not just more software.
