Our Mission -
Make GTM Simple

The problem with most AI isn’t potential — it’s complexity. Sales leaders are promised transformation, but instead face disconnected systems, unpredictable revenue, and teams stuck reacting instead of executing.

We help you cut through noise and recommend the right strategy, tools and solutions
Our focus is on adoption and impact — not just aspiration
We turn AI from hype into measurable results


25+Years GTM Sales Experience

We’ve been sellers, sales leaders, product managers, product marketing managers and founders — and we’ve exited. At OneSales, we turn that experience into AI-driven solutions that simplify sales and accelerate growth.

2000+
GTM Leaders

We’ve worked with over 2,000 go-to-market leaders — from CROs and RevOps to frontline managers and enablement teams.
We know the state of sales because we’ve lived it, not made it up as we go.

Tools, Technology, and People

We understand technology, tools, and people.  At OneSales, we design and implement solutions that are elegant, easy, fast, and cost-effective — built for adoption, not just aspiration.

A Message From Our Founder

At OneSales, we know how tough today’s sales environment has become. 
Go-to-market teams are asked to adopt AI, move faster, cut costs, and still grow revenue. Yet most projects stall. Too many tools, too many claims, too little impact.

We built OneSales because we’ve lived this ourselves. Between us, we’ve worn every hat — sales reps, CROs, founders, product marketing, product builders. We’ve implemented systems teams actually used, led hundreds of enablement projects, and seen firsthand what works (and what doesn’t). Our DNA isn’t just technology — it’s selling. We understand the people who rely on it every day.

With gratitude,

Seamus Devine
