We are the specialist B2B go-to-market agency that understands today’s changing challenges, equipping you with smarter solutions that align every element of strategy, execution, marketing and sales enablement.

Our story
Our team
Work for us

OneGTM was established in 2011 with the aim of creating a new type of agency – one that combines the best bits of a B2B marketing agency with the insights and expertise of a strategic go-to-market consultancy.

We (that’s founders Tim Hallac and Phil Brown) identified the opportunity to deliver better results for clients by bringing together consulting expertise, industry experience, creative marketing talent and robust project management in a single team.

We created OneGTM because we believe that to succeed in today’s technology market requires a smarter go-to-market approach, where each element of the go-to-market mix is fully aligned, where channels are properly engaged and enabled, and where insight is combined with creativity to produce compelling propositions and campaigns.

With OneGTM we’ve built a team capable of delivering fully joined-up go-to-market programmes that are based on real-world market insight and a proper appreciation of what it takes to succeed with today’s well-informed B2B buyer.

Our consulting team have all held senior sales, marketing or channel roles in the technology and telecoms industries. Our marketing team offer the creative thinking and delivery expertise to bring strategies to life and ensure effective execution.

We began as The Channel Partnership but rebranded as OneGTM in January 2015 to better reflect the value we offer to clients – end-to-end support to deliver fully aligned go-to-market programmes. In January 2017 we merged with B2B marketing specialists, Mabox, to strengthen the team.

We’re proud of the fact that in 6 years we’ve built an impressive list of clients, including some of the leading brands in the technology and communications sectors. We’re even prouder that nearly all of the clients we’ve worked with have engaged us on multiple projects. So we like to think we must be doing something right.

In recognition of our recent work, in recent years we've also received a B2B Marketing award and won the CRN Best Channel Agency award.

So that’s the story so far. If you’re interested in being part of the next chapter please don’t hesitate to get in touch – phil@onegtm.com or tim@onegtm.com

Phil Brown

Managing Director

As OneGTM’s strategy and planning expert, Phil works closely with OneGTM’s clients to ensure they have the strategies, propositions and plans that underpin their go-to-market success.

Phil brings to the role a breadth of experience in the technology and communications sectors. As OneGTM’s MD he’s consulted with many of the industry’s leading brands. Prior to founding OneGTM, Phil had a successful career ‘client side’, which included managing new business and enterprise account sales teams, heading up a marketing function, leading a large-scale digital transformation programme, and running a cloud software business. This diverse experience gives Phil an in-depth understanding of the different facets of the go-to-market mix, and an appreciation what it really takes to build pipeline and close sales.

When not working, Phil’s something of a music nut – so if you've got a few hours/days/weeks to spare, ask him about his current favourite artists and tunes. He's also a keen skier, an enthusiastic (if limited) tennis player, and a long-suffering West Ham fan.
