Seth Marrs | 2026: The Year of Sales Effectiveness

Most revenue teams have more tools, more data, and now more AI than ever before.So why does execution still break down under pressure?That is one of the core tensions behind 'The Era of Precision Growth in B2B: A GTM Motion Powered by Data', part of the 2026 Growth Imperatives created with leaders across Trilliad, Sercante, and Sandler.Because the problem is no longer access to information.The problem is turning that information into execution that actually sticks.Training happens.Enablement gets rolled out.AI gets added.But too often, sellers still fall back into old behaviors.Managers detect it late.And leaders still struggle to prove whether all this investment is improving performance or just increasing activity.That is why this conversation matters.In this episode of The Sales Strategist, I sit down with Seth Marrs, Chief Strategy Officer at Sandler, to unpack that exact shift: from efficiency to effectiveness, from one-off training to sustained execution, from enablement participation to financial proof... and way more.
