When marketing becomes the constraint.

Growth has slowed.

Pipeline is weaker than the plan and nobody agrees on the real constraint.

The company has changed.

New funding, an acquisition or a restructure now needs a credible marketing plan and budget.

The model no longer scales

Referrals, founder-led selling or a single acquisition channel can no longer carry the target.

Marketing needs leadership now.

A launch, repositioning or leadership gap needs experienced ownership before momentum is lost.

RECOMMENDATIONS

What it’s like to work with me.

“Tomas joined Saville when we needed a genuine marketing reset, not another layer of advice. He built the strategy and budget behind our growth plan, secured the backing to execute it and repositioned the business. He then led the Wave Connect launch, rebuilt demand generation and RevOps, and reshaped the marketing team around qualified pipeline and growth.


Throughout the transformation, he was equally comfortable making board-level decisions and getting into the detail with the team. He brought the judgement, pace and hands-on leadership needed to turn the plan into a working marketing system.”

MORE RECOMMENDATIONS

“I’ve worked with Tomas across several companies. He looks at the business first, not whichever marketing tactic is fashionable that month. He finds the real problem, explains it simply and works with the team to fix it. We’ve seen stronger revenue numbers because of that. He is smart, practical and easy to work with, even when he tells you something you don’t want to hear. When growth gets stuck, he is one of the first people I call.”

“Tomas and I worked together on the zero-click research we jointly published. That research was among the most impactful, widely read and influential in the field.

It was cited by the Department of Justice, the US Congress and the FTC chair. Tomas’ data, project management and comms skills were invaluable in making that work a reality.”

“Tomas is unusually good with people. Customers listen to him, teams trust him and colleagues want him involved.

He can represent the company in any room, then move directly from strategy into practical execution.

He is one of the most complete marketers I’ve worked with.”

YOUR DASHBOARD SEES 3%. AI IS INSIDE 9 IN 10 SOFTWARE DECISIONS.

2026 REPORT

TOMAS SELIOKAS / B2B SAAS CMO

FEATURED RESEARCH

Your dashboard sees 3%. AI is inside 9 in 10 software decisions.

I reviewed 221 AI visibility research publications and reports to understand how AI is changing B2B software discovery, comparison and shortlist survival before conventional attribution begins, and what high-value B2B SaaS CMOs should fund, measure and test now.

Different studies. Different denominators. This exposes a measurement gap, not AI-caused pipeline or revenue.
