About

Commercial judgment, made operational.

Accelerate Atelier works with leadership teams that have outgrown informal sales management but do not want heavyweight transformation theater.

Experience that starts with the commercial reality.

Mark Southgate brings more than a decade of B2B sales experience across software companies and consulting firms.

He has worked with the pressure that comes with complex sales cycles, ambitious growth plans, uneven pipeline quality, and executive scrutiny of the forecast. In consulting, Mark has advised on digital transformation projects for some of the largest brands in the technology sector, connecting commercial priorities with the practical work of changing how teams operate.

Since 2023, Mark has focused on building Accelerate Atelier, a go-to-market and sales consulting firm. His experience on both the sales and advisory sides of the table means he can relate to the constraints leaders and their teams face: decisions still need to be made, customers still need to be won, and operating change has to work in the real world—not just on a slide.

Point of view

Revenue problems are usually management system problems.

Missed forecasts, slipping deals, slow pipeline conversion, and confused GTM priorities often trace back to unclear definitions, weak inspection cadence, and forums that do not force the right decisions.

The advisory model is practical: diagnose the current operating rhythm, redesign the few mechanisms that matter, and coach leaders through adoption until the system becomes normal.
