RightSize Marketing

Go to Market for first-time Founders and CEOs

RightSize Marketing is a boutique consulting firm specializing in go-to-market (GTM) strategy, positioning, and product-market fit validation for SaaS and AI startups. Founded by Mark Cowtan, a marketing strategist with 25 years in Silicon Valley rising through the ranks to CMO, and over a decade helping startups get to market and avoid common launch mistakes with actionable GTM strategies that turn ideas into thriving businesses.

Consultants love to give advice. But Advice alone, doesn’t move the needle.

Founders need partners that take action. That’s where we come in.

My team and I roll-up our sleeves, and do it with you, or for you.

What We Do Best

Go-to-Market Strategy & Execution – A clear, actionable roadmap to launch and scale.

Product-Market Fit Validation – Test demand before building to ensure market traction.

Positioning & Messaging – We craft competitive positioning that make you hard to ignore.

Lead Gen & Demand Creation – Proven strategies to turn cold leads into loyal customers.

Funnel Troubleshooting – Pinpointing what’s holding you back and fixing it fast.

Why Work With Us?

Most startups don’t fail because of bad products—they fail because their GTM strategy is weak. We take a no-fluff, execution-focused approach to help founders refine their market positioning, validate demand, and create scalable growth. If your startup needs a smart, actionable GTM plan, let’s talk.
