About Mark Colgan

Let’s be real.your outbound isn’t working. SDRs are blasting emails and making dials, but meeting rates are flat. Discovery calls start strong, then ghost town. Pipeline is unpredictable, and scaling feels like chaos. Every week you lose hours chasing prospects that never reply. Every quarter you miss revenue targets by 10–20% because pipeline isn’t full. Meanwhile, competitors are running structured outbound systems that win the deals you should be closing. I help B2B SaaS GTM leaders fix broken outbound and turn it into a repeatable revenue machine- Consistent reply rates (from <1% to 7%+)- SDRs who book more meetings with confidence- AE's who close deals 30% faster- A repeatable system that grows with your team. No more excuses. No more “spray and pray” outbound. No more wasted effort. Instead, a clear playbook and pipeline you can rely on. 295% increase in Net New MRR for a SaaS team. 64% increase in closed won deals in under 6 months. Trusted by GTM Leaders, VPs of Sales, SDR Managers, and Founders across Series A–D B2B SaaS. Known as the “go-to guy for outbound sales” by clients who were in your exact spot. I’ve trained, audited, and advised hundreds of sales teams, bringing both strategy and hands-on execution. Tired of burning cash (and energy) on broken outbound?

I spend a lot of time trying not to get too sun burnt (even in winter). I’m an average golfer, getting into cycling and love travelling. You’ll often hear me saying “por que no?” (why not?) to anything that sounds fun or gets the heart racing like wingwalking, skydiving and paramotoring- Fun fact time: 1⃣ I once fooled London into thinking a 🦊 cafe was opening 2⃣ Prior to my Sales and Marketing career I was a model 3⃣ I spent 10 days on a deserted island in Panama
