Kaustubh Wadhwa — Co-Founder
Founding team member at Zapmail.ai, building the cold email infrastructure that powers growth for thousands of teams. Alongside an incredible team, we’re solving the hard problems of deliverability—helping revenue teams focus on relationships instead of servers. Since joining in early 2024, we've scaled to $10M ARR in just 13 months. I previously helped launch ReachInbox.ai, an AI‑powered outreach tool that automates personalized sales sequences for small and midsize businesses. My journey from product marketing to startup builder has been a continuous cycle of experimenting, learning, and scaling. Each role taught me to focus on customer value and sustainable growth. What I bring: • A builder’s mindset: turning ideas into products and processes that scale. • Data‑driven growth: experimenting, measuring, iterating to find repeatable growth levers. • Learning and sharing: I openly share wins and lessons to help other founders and teams. If you're building B2B SaaS, facing deliverability challenges, or curious about AI‑driven outbound, let's connect. I'm always learning, building, and eager to collaborate with fellow builders and learners.
