We did not read about selling. We do it.
Clario comes out of a working agency, not a business school. Every week we are on calls with people who have never heard of us, in markets that owe us nothing, trying to earn a meeting. The method we teach is the one we use on Tuesday morning.
We run Viral, a digital marketing agency. Performance campaigns, outbound, account-based marketing, analytics — the whole unglamorous middle of a business trying to grow. That work means two things that matter here.
The first is that we sell for a living. Not as a case study — as the thing that pays the salaries. We have opened markets from a standing start, written the cold email that got the reply, taken the call where the buyer already had a supplier, and lost plenty of them before we learned why.
The second is that we have watched the same failure from the inside of dozens of companies. A business spends everything getting a lead to raise a hand, and then hands that lead to someone who was never taught what to do with it. Marketing is measured to death. The sales call — the most expensive minute in the business — is measured by nobody.
Clario exists to close that gap, and to do it in every market we can reach. Selling in Milan is not selling in Dubai and is not selling in Tel Aviv — the discipline is the same, the manners are not, and a coach that cannot tell the difference is not much of a coach.
The methodology is bigger than the AI
Marketing changes every other day. Selling does not — what worked in 1700 works in 2026, because it was never about the channel. If the model is the whole product, anyone can copy it by Friday. The method is the part that cannot be copied.
Most people walk into a sales call like it is an exam
Something to survive, rather than something to lead. The single best piece of advice either of us ever got was to walk in as if there were a hundred million dollars already in the bank — because the person who does not need this deal is the person who can hear the buyer.
Nobody is a lost cause
The quietest person in the room is not bad at selling. They are being asked to perform someone else's personality. A coach that only asks questions can train anyone — and that is exactly what we built.
A seller should own their number
Not a review once a year. A level, earned, that travels with them, that they can be proud of, and that a company can hire against.
One sells. One teaches. Both do both.
Rafi Atias
Chief Executive OfficerA trained coach who has spent years running projects, and the people inside them. Mindful Sales is his — the discipline of walking into a conversation knowing where it is going, asking rather than declaring, and hearing your own state before it costs you the room. He is teaching that method to the coach, one session at a time.
Yossef Zilberberg
Chief Technology OfficerFounder of Viral. He built the agency by selling it, market by market, and then built the teams that sell for it. Inside Clario he builds the thing itself — the coach, the scoring, the systems that carry the method to a floor we are not standing on. When he says a call was lost in the first ninety seconds, it is because he has lost calls in the first ninety seconds.
Built in Israel, taught anywhere someone has to pick up the phone.
The method is portable; the manners are not. Clario is being trained on real calls, in real markets, so that it knows the difference between a buyer who needs three questions and a buyer who needs silence.
