What Would an Independent Slack Look Like If It Hadn’t Sold to Salesforce? And Would It Still Be Worth $27 Billion?

Julian Lehr's question on X hit a nerve that every founder knows too well: what if Slack had never been acquired by Salesforce, staying in the hands of its creators and pivoting hard into the AI era? It is a counter-factual that forces us to strip away the corporate baggage of the enterprise cloud and see what pure product obsession could look like in 2024. We are currently living in a world where Slack is often viewed through the lens of a Salesforce sub-feature, a utility that must play nice with complex ERP systems rather than leading the charge on conversational intelligence. Imagining an independent Slack means imagining a company with the singular, unadulterated mandate to make teams work better, free from the quarterly revenue pressures of a massive conglomerate that needs to cross-sell insurance and CRM modules.

The trajectory of an independent Slack would likely have been defined by a different kind of risk profile. Instead of the cautious, feature-bloat-heavy rollout we see today, an autonomous Slack might have embraced the chaotic, rapid iteration that early AI companies are known for. They would have been able to burn cash on experimental features like persistent memory for threads, proactive agent suggestions, or deep context-aware summarization without needing to justify them to a board of directors worried about integration compatibility with legacy Salesforce objects. The product would likely feel less like a communication tool and more like a cognitive layer over your entire digital workspace, anticipating needs before a human even articulates them.

Valuing this hypothetical entity requires looking past the $27 billion acquisition price tag, which was a premium paid for the synergy of connecting chat with customer data. Without that synergy, the valuation logic shifts entirely to growth rates and product stickiness. If an independent Slack had grown its Annual Recurring Revenue (ARR) to $2.5 billion while maintaining a healthy 25% growth rate, the market might have valued it differently based on pure software multiples rather than enterprise integration potential. The absence of Salesforce's massive infrastructure means the margins would be tighter due to the cost of building everything from scratch, but the gross margins on core messaging could be healthier because there are no legacy code taxes to maintain.

The real tragedy of the "what if" scenario is not just about missed features or different stock prices, but the loss of the founder's soul in the enterprise machine. The early Slack team operated with a scrappy, almost reckless creativity that prioritized user delight over enterprise governance. An independent Slack today might not be the most secure or compliant platform for a Fortune 500 bank, but it could be the most innovative engine for human collaboration in the world. The current iteration of Slack, while robust, often feels like a product designed to survive a merger rather than one designed to dominate a paradigm shift. The AI revolution demands a platform that can think with you, not just host conversations about your work.

Ultimately, this thought experiment highlights the harsh reality of the modern SaaS landscape: independence is a luxury that most companies can no longer afford, and acquisition is often the only path to scale. However, for the sake of the industry, we must acknowledge that the alternative—a purely founder-led Slack—might have offered a glimpse of what true AI-native collaboration looks like. It serves as a reminder that while scale brings stability, it can also dilute the very instincts that made a product great in the first place. As we watch the current iteration of Slack navigate the AI wave, we are left wondering if the version we have is the best possible world, or just the one that survived the merger.
