Seán Livingstone | Chief Sales Engineer

I help C-level and GTM leaders design and deliver high-value solutions that win the technical decision, accelerate revenue, and strengthen trust. My focus is simple: Sales Engineering that sells, solves, and scales.

Over two decades, I’ve built and led Sales Engineering teams and scaled presales functions in enterprise environments. My approach is fact-based, disciplined, and artefact-driven, so teams can execute consistently under pressure.

Revenue up 15%. Productivity up 20%. $40M+ contributed through SE leadership and process transformation.

Baseline, scope, and timeframe vary by team.

• Operating model design and rollout (roles, stages, handoffs, standards)

• Deal craft and proof motions (demo, validation, PoC gates, success criteria)

• Commercial fluency for technical teams (value narrative, qualification, decision support)

• Performance loops (what to measure, how to review, how to improve)

Apex Edge Sales Engineering is where I publish the frameworks and field lessons behind this work.
