Growth playbook for underdog SaaS founders | Vaios Gkitsas - Upset Partners

In this engaging episode of the Tekpon SaaS Podcast, hosted by Cristian Dina, the spotlight is on Vaios Gkitsas, Founder of Upset Partners. Upset Partners is a go-to-market studio designed explicitly for B2B SaaS startups in the real estate sector, focusing on companies from the pre-seed stage up to Series A. They leverage a tested framework with their resources to help founders with outbound sales strategies and handle the entire sales funnel, from lead generation to closing deals.

Vaios delves into the core of its operations, describing how it works alongside founders to craft a go-to-market strategy tailored to a business’s specific needs. Assessing market dynamics, key business strengths, and initial traction helps founders refine their approach. Notably, Upset Partners doesn’t just offer strategic advice but also implements the agreed-upon strategies using its own resources. This end-to-end service ranges from lead generation to demo participation and closing sales.

Discussing common mistakes founders make, Vaios identifies three significant pitfalls: an unclear understanding of the problem they aim to solve, targeting too many verticals and personas instead of narrowing down to a niche, and hastily chasing revenue instead of focusing on the ideal customer profile (ICP). He emphasizes the importance of founders transitioning from relying on personal networks to creating systemized, scalable sales processes.

Vaios also shares his involvement in the B2B SaaS community through initiatives like Sastock, where he serves as the city leader for Athens. He expresses a passion for fostering local ecosystems, highlighting his efforts to build a strong community in Greece.

Overall, this episode offers valuable insights into the challenges and strategies involved in scaling B2B SaaS startups, emphasizing the critical role of a well-defined go-to-market strategy and the support ecosystem provided by Upset Partners.
