Sarah Mouton

I help start-ups and scale-ups turn their product vision into scalable growth. With over a decade of experience in building and executing go-to-market strategies, driving product-led growth, and scaling partnerships, I specialize in guiding founders and leadership teams through critical inflection points.
As a former key player in PieSync’s growth (leading to its acquisition by HubSpot) and having relaunched Developer Partnerships at HubSpot, I bring hands-on expertise in scaling B2B SaaS businesses, ecosystem strategy, and operational execution. My experience bridges the gap between product, growth, and partnerships, helping companies navigate the challenges of early traction, product-market fit, and sustainable expansion.
Companies that would benefit most from my expertise:
• B2B SaaS companies looking to refine their product strategy and accelerate growth.
• Start-ups and scale-ups navigating the transition from founder-led sales to scalable, repeatable revenue.
• VC-backed companies needing advisory support in growth strategy, go-to-market, and partnerships.
• Companies building an integration ecosystem or leveraging product-led partnerships to drive distribution.

As an advisor or board member, I provide strategic insight while staying execution-minded—ensuring that vision turns into action and measurable impact.
