B2B Marketing Consulting Agency Passionate over Business Marketing Since 2001

Measuring everything that matters and aligning Sales & Marketing to optimise revenue outcomes.

Who We Are

Our digital marketing consulting agency is a diverse blend of B2B marketing professionals – from seasoned consultants to rising stars, with a wide range of skills, perspectives and backgrounds.

We don’t limit our thinking and contributions to our titles and we encourage diversity of thinking and approach. We know we are measured by our clients’ success, so we keep that top of mind.

Our mantra is ‘Good to Great. Innovate’. To get from good to great (thanks to Jim Collins and his book of that name), we know we need to continually find smarter ways for our clients to engage with their target audience. Each team member is tasked to be the expert in a nominated digital area, to challenge the way we do things today and set new standards.

We’re Helping Kiva Help Others

Kiva is a non-profit organisation with a mission to connect people through micro-finance lending to alleviate poverty.

We like what they do. We support Kiva borrowers in the developing world by lending directly from Green Hat, and on behalf of our clients.

Kiva enables individuals to lend as little as $25 to help create opportunity around the world. Kiva envisions a world where all people – even in the most remote areas of the globe – hold the power to create opportunity for themselves and others.

100% of every dollar we lend on Kiva goes directly towards funding loans. We like that too. Kiva is primarily funded through the support of lenders making optional donations and also raises funds through grants, corporate sponsors and other philanthropic foundations.
