Kate Piselli Promoted to VP of Product at Slack

Slack has promoted Kate Piselli to Vice President of Product, where she will lead the company’s product-led growth strategy.

Piselli’s expanded role comes as collaboration software companies increasingly focus on product experiences as a key part of customer acquisition, adoption, and retention. Rather than relying solely on traditional sales and marketing channels, product-led growth places the product itself at the center of how users discover, evaluate, adopt, and expand their use of a platform.

In her new position, Piselli will focus on the product strategies that support this approach, connecting user experience, product adoption, and business growth.

The shift toward product-led growth reflects broader changes in the B2B software market. Buyers increasingly research and evaluate technology independently before engaging with sales teams. Free trials, self-service experiences, product demonstrations, integrations, and in-product guidance can therefore play an important role in influencing purchasing decisions.

For marketing and product teams, this creates a closer relationship between product development and customer engagement. Product usage data can provide insights into user behavior, while marketing teams can use those signals to develop more relevant communications and engagement strategies.

Artificial intelligence is also changing collaboration software and product experiences. AI-powered assistants, automated workflows, search, summarization, and personalization are becoming increasingly common across workplace platforms. These developments are raising expectations around how quickly users can find information, complete tasks, and collaborate.

Piselli’s promotion highlights the growing importance of product leadership in shaping these experiences. Product organizations are increasingly working alongside marketing, sales, customer success, and data teams to understand customer needs and translate those insights into product decisions.

For Slack, a stronger focus on product-led growth comes as workplace communication continues to evolve across distributed teams, digital workflows, and increasingly AI-enabled work environments.

The appointment reflects a wider industry trend in which product leadership is becoming more closely connected to go-to-market strategy. As software companies seek to improve adoption and long-term engagement, the product experience itself is increasingly becoming an important part of the customer journey.
