Episode 135: Sales Confidence, Open Source GTM, and Winning Developer Trust

In this episode of #TheGTMPack podcast, we sit down with Aleksandra Mitroshkina, a product marketing leader based in Istanbul, who helps SaaS companies grow their share in saturated markets.

Aleksandra brings a unique lens to product marketing, shaped by her early career in sales and product development. She’s especially passionate about Sales Enablement, go-to-market strategy for Open Source products, and applying agile methodologies to the PMM discipline.

In this conversation, we dive into what it takes to market to skeptical developer audiences, how to turn open source users into paying customers, and why measuring sales confidence might be one of the most underrated tools in your go-to-market toolkit.

Key takeaways:

💡 From Sales to PMM: How a Cross-Functional Background Builds Better Marketers
Aleksandra shares how her experience in both sales and product development has made her a more well-rounded product marketer. Understanding how deals are won and how products get built gives her a clear edge when it comes to positioning, enablement, and cross-functional collaboration.

💡 Marketing Open Source Products Requires a Different Playbook
Selling to developers isn’t about splashy campaigns or hard sells. Aleksandra explains why trust, community, and education are crucial when marketing open source, and how product marketers can meet developers on their terms.

💡 Sales Confidence as a PMM KPI
Measuring sales confidence helps PMMs understand how well sales teams are enabled and where the gaps are. Aleksandra walks through how to run these surveys effectively, what questions to ask, and how to use the results to improve alignment, training, and ultimately—revenue.
