Category Visionaries Darko Vukovic, CEO & Founder of PolyAPI: $5 Million Raised to Transform Enterprise Middleware Through Native Code Development
In this episode of Category Visionaries, we explore PolyAPI's journey to revolutionize enterprise middleware. As a category maker in the integration space, PolyAPI is challenging traditional low-code/no-code approaches by enabling developers to build robust enterprise integrations using native programming languages. Through conversations with Darko Vukovic, we learn how his deep industry experience and strategic focus on developer-first principles are reshaping how enterprises approach connectivity and integration challenges.
Topics Discussed:
- The evolution from enterprise integration platforms to native code development
- Building credibility in enterprise sales through transparency and documentation
- Creating a new market category between iPaaS and application development
- Strategic fundraising approaches for deep tech startups
- Future vision for AI-powered enterprise connectivity
GTM Lessons For B2B Founders:
- Build credibility through transparency: Rather than hiding their product behind NDAs, PolyAPI published detailed demos and documentation early. Darko explained, "We think that our domain and our product set is just so hard to copy and replicate... so we were never worried about competitors catching wind of what we're doing." This transparency helped enterprise buyers see that PolyAPI wasn't vaporware.
- Target technical decision makers with depth: PolyAPI succeeded by focusing on enterprises that had already rejected low-code platforms and were building in-house solutions. This created a clear target market of sophisticated buyers who understood the limitations of existing solutions and were willing to adopt a new approach.
- Start marketing through 1:1 engagement: Instead of broad marketing campaigns, PolyAPI began with individual conversations to gather feedback, find alpha testers, and evolve into beta testing. This grassroots approach helped them refine their product and messaging before scaling up marketing efforts.
- Find investors who deeply understand your space: Out of 20 initial VC conversations, 19 passed, but Ross Mason (Mulesoft founder) immediately invested. Darko noted, "That kind of signal is really important because the one person who deeply understands the space was super excited to invest." This validated their approach and provided valuable strategic guidance.
- Build relationships with VCs continuously: Even six months after their latest round, PolyAPI is already preparing for Series A by maintaining relationships with 20+ VCs and working toward clear metrics. This ongoing engagement creates leverage for future fundraising by demonstrating consistent progress.
