About our Founder and Director
At the heart of Certitude & Co., is founder and CEO Kirby Mamo, a marketer with an innate creative instinct and a deep understanding of the digital space. Kirby's marketing career began with her own personal success growing an audience of over 40,000 Instagram followers alongside 250,000 followers on TikTok and cultivating 13.5 million likes, a true testament to our natural ability to connect and engage with an audience authentically and genuinely.
Despite this success Kirby‘s true passion was never being in the spotlight… it was creating it for others. She shifted her focus to building a business from the ground up that combines creative flair with a rigorous results-driven mindset. Today she leads Certitude & Co., with heart and a fierce dedication to helping brands stand out from the rest.
Currently completing a double degree in Psychology and Marketing and Media at Macquarie University, Australia’s number one ranked marketing program, Kirby brings a depth of insight to her work. Her unique combination of consumer psychology, digital marketing and strategy knowledge, and lived experience as a content creator gives her clients a rare competitive edge allowing her to build strategies that resonate not just algorithmically but emotionally.
Driven by excellence and grounded in intention, Kirby is aiming to redefine what it means to lead a modern digital marketing agency. Her mission is simple: helping brands rise with purpose, grow with certainty, and make their mark in a crowded digital landscape.

This unique combination of academic alongside real-world experience within the social media landscape, gives Certitude & Co., a unique lens to craft strategies that not only reach but also resonate with audiences. We don’t chase trends; we build enduring, holistic strategies that prioritise organic growth and meaningful engagement. Throughout our process, we ensure we equip you with the knowledge and tools to understand the why behind our work. Whether you’re scaling with us long-term or taking strategy in-house we want you to feel more than competent, capable and creatively empowered.

We are proud to say that we have helped businesses grow to be fully booked and implementing client waitlists and exceeded the benchmark set by our competitors who have been in the game for years before us. .
