Who is Steli Efti?

Steli Efti is the co-founder and CEO of Close, the CRM built for startups and small sales teams that want to make more calls, send more emails, and close more deals from a single tool. He is one of the most recognizable voices in SaaS sales, known for a blunt, high-energy style and a conviction that selling is a learnable skill rather than an innate talent.

Before Close, Efti spent years on the front lines of startup sales, including running an outsourced sales operation that placed his team on the phones for dozens of early-stage companies. That experience — thousands of real sales calls across wildly different products — became the raw material for the frameworks, scripts, and playbooks he is now known for teaching.

He took the stage as a keynote speaker at SaaStock Europe 2017 in Dublin, where he walked founders through the anatomy of a strong SaaS sales call. This page collects his recorded SaaStock appearance, with transcript.

About Close

Close is an inside-sales CRM designed for startups and SMB sales teams. Rather than acting as a passive system of record, it puts calling, emailing, and follow-up directly into the workflow so reps spend their time selling instead of doing data entry — a reflection of Efti's belief that the best sales tool is the one that gets out of the way.

The product grew out of Efti's own hands-on sales work, and its design philosophy mirrors the advice he gives from the stage: focus on activity that actually moves deals forward, qualify hard, and build a repeatable process you can coach a team through.

Originally launched as Close.io, the company is now known simply as Close and remains focused on helping founders and small teams build an effective, high-velocity sales motion.

Key lessons from Steli Efti's talks

Treat the sales call as something you can design. In his 2017 SaaStock keynote, Efti's core premise is that a great call isn't luck or charisma — it has a structure you can deliberately build, rehearse, and improve, the same way you would any other part of the product or funnel.

Bring energy and presence to every interaction. Efti models the exact posture he argues founders need on a sales call. Conviction and engagement are part of the method, not a personality quirk — and they're contagious to the person on the other end of the line.

Don't assume the prospect knows or cares who you are. A running thread in Efti's approach is humility about your own importance: most prospects have no idea who you or your company are, so the call has to earn attention and establish relevance fast rather than coasting on assumed authority.

Make selling a teachable, repeatable skill. Efti's whole body of work — from his on-stage frameworks to the tooling philosophy behind Close — rests on the idea that sales can be broken down, scripted, practiced, and handed to a team, instead of living only in the head of a gifted founder.
