Founding Account Executive | Build Revenue Engine, Become Head of Sales

Most B2B companies are operating blind.

They cannot see:

• when competitors are winning deals
• when customers are about to churn
• when key accounts are entering renewal

So they default to guesswork and weak intent data.

We call this Signal Blindness. MarketSizer fixes it.

We give SaaS GTM teams real visibility into:

• competitor trials
• active subscriptions
• churn risk
• renewal timing

Built on real subscription behaviour, not noise. We focus on revenue outcomes, not busy work. You spend less time on activity and more time closing the right deals.

We are early. The product works. Now we’re looking for someone to turn that into repeatable revenue, backed by a team that moves fast and supports deals in real time.

We move fast and ship even faster. If something blocks a deal, we fix it.

• Flat organisation. Best idea wins.
• Ownership is real. So is accountability.
• Constructive challenge is expected.

The Role

You will operate at the intersection of sales, product, and GTM.

• build pipeline
• close deals
• shape how we sell

If you get it right, you become Head of Sales.

What we're looking for

• 5 to 10 years B2B SaaS sales
• Strong outbound experience
• Proven ability to close from early traction
• Comfortable in an early stage environment

Comp

• €65K base
• €130K OTE
• 0.5 to 1.5 percent equity

Location

• Dublin, Ireland
• Hybrid setup with a mix of office and remote
• Must have an existing valid work permit

If you can turn early traction into a real revenue engine, with a team fully behind you, this is for you.
