I build the systems that turn marketing into pipeline you can measure.

GTM engineering for B2B SaaS teams. Attribution, enrichment and CRM workflows across HubSpot, Salesforce and Clay, built so your team can run them after I'm gone.

Growth strategy and GTM engineering overlap in measurable pipelineTwo overlapping circles. Left: growth strategy, covering demand and funnel. Right: GTM engineering, covering CRM and attribution. The shared area is labelled pipeline.GrowthstrategyDemandFunnelGTMengineeringCRMAttributionPipeline
Growth strategy decides where pipeline should come from. GTM engineering builds the systems that capture, route and measure it. I work where the two meet.

Three problems I fix

You can't say which campaigns create pipeline.

I connect forms, CRM and opportunity data so every deal has a source you can defend in a board meeting.

Your CRM is full of half-records.

Enrichment and cleanup that give sales complete accounts, not a list of email addresses.

Good leads wait too long.

Scoring and routing that get the right lead to the right rep while they still remember filling in the form.

How it works

  1. Audit, two weeks

    A ranked list of what to fix, what to build and what to kill, with effort and cost for each.

  2. Build, fixed scope

    One system at a time, priced up front.

  3. Hand over

    Documentation and a recorded walkthrough, so it keeps working after the project ends.

What people say

“Rónán's efforts saw dramatic results - with lead volume increasing by 44% y/y during the latter 9 months of the year. This was one of our critical goals and we could not have done it without him. Rónán has a wide knowledge of SEO, SEM, and strategy - he is our digital backbone and keeps our online presence thriving. He is data-driven, and encourages the team to ask 'what was the result of that' when we evaluate campaigns and channels.”

Christina Martinez
CMO, Foothold Technology

“Sometimes you have to take a step back before you realize some of the great work that is being performed before your very eyes. I think about this with Ronan. We can look at a key marketing metric like MQLs (marketing qualified leads) in which we are almost at 700 this year [for context last year we were at about 560] and think - oh that is great. But when you think about the tremendous amount of work behind that increase it blows my mind. Ronan has lead the charge. His position is often in the shadows, but he really has pushed our digital efforts to the light!”
