Fractional Marketing Head at Leadstack
Hi, I’m Venkatesa Madhan (Venky) — a marketing leader with 19+ years of experience driving demand generation, digital strategy, and growth for global B2B tech and SaaS companies.
I've led high-impact marketing teams, scaled inbound and outbound programs, built GTM strategies from scratch, and helped organizations break through revenue plateaus. My experience spans Fortune 500s, high-growth startups, and everything in between — with a focus on product marketing, martech architecture, and data-driven growth.
Today, I work closely with CXOs and founders to shape marketing functions that align with business outcomes — from pipeline to brand.
If you're a marketer looking to break into B2B SaaS, a founder shaping your first GTM motion, or a professional pivoting into demand gen or product marketing — let’s connect. I’d be happy to share what I’ve learned, mistakes I’ve made, and help you move forward with clarity.
