About me…

I have over 14 years of experience in B2B SaaS Sales and Marketing having worked at FTSE 50 companies, bootstrapped startups, agencies to venture-backed scale-ups.

I started off as a recruitment consultant, then moved into Marketing before transitioning into quota carrying leadership roles.

In Dec 2022, my Podcast PR agency was acquired after we grew a team to 22 remote workers, secured 2,200 podcast interviews for over 120 companies, including well known B2B SaaS brands like Gong, Paddle, Hopin and many more.

After taking off 6 months in 2024, I settled on the idea of helping frustrated Agency Owners with their revenue challenges via a new company Agency Sales Design.

I’m also Techstars 18′ Alumni and a regular speaker within the B2B SaaS industry, having been published by SaaStock, Mailshake, Pipedrive, LeadSift, Lemlist, SugarCRM and Baremetrics to name a few.

I currently live and work from Lisbon, Portugal and I’m addicted to travelling and exploring new cultures and places.

You’ll often hear me say “por que no?” (why not?) to anything that sounds fun or gets the heart racing like wingwalking, skydiving and paramotoring.

Speak With Me

Each week, I allocate a few hours a week to give back to founders growth professionals by offering 1:1 mentoring to those who are starting and growing their businesses via GrowthMentor.
