For years I misunderstood how trust actually works and naively imagined it's about doing good, being serious, and delivering what was promised. While this is important, it was not enough. So what's enough ? We are engineers we need a number !
📚 The Zero Moment of TruthI discovered this concept first from Daniel Priestly (Key Person of Influence) which referred to a research Google made "The Zero Moment of Truth", marketers started to call it "The 7-11-4 Rule" (which typically states that potential buyers spend 7 hours researching , use 11 sources , and visit 4 different locations ). The scholars here can read this / Credits to Sophie Lüttish​ I want to call for our context "The Earned Trust Formula "Regardless of whether we are employees, self-employed or business owners : we are selling. Selling our time/energy (employees), our expertise (self-employed), our products and services (business owners). So when I mention "Selling/Buying" think "Hiring" for employed and self-employed members.
Why it matters?As an engineer I have to train my communication 💪🏼 muscle, so that when I share my ideas, my projects, my offer, my expertise ... people who want it trust me enough to "act" by buying. What took me ages to realize, is that there is an emotional journey buyers go into beyond making a purchase, and if I think about it, it's the same I go through when I am buying something for myself :
The mistake as I do as an engineers, is being too rational in the early stages of the sale. It's a no brainer ! it makes sense, you buy for $500, and you get 10x in ROI. I learned this could kill an opportunity in the egg. Especially when I think of myself as humble, serious and trustworthy. Because I know that about myself, so I don't understand when other people don't trust me....... And it's just because :
How could the 7-11-4 work for us?Humans can only process and remember a finite number of people. It's around 150, the Dunbar's number. People we can maintain relationship with. So when we are a nobody to someone, we have to realize we are in competition with 150 pre-existing relationship already getting their attention. So, for someone new, we need to earn their attention and trust, by building up the relationship account. So, a one-shot campaign won't make it, a big deal ad won't cut it, hiring a sales director won't solve it. What the study shows is that it takes any human who doesn't know you, your expertise, your product/service (on average) at least 7hours (time) of exposure to it, seeing it 11 times (frequency) and in 4 different locations (or touchpoints). Think about how you become friends with someone : you see each other over a long periods of time, often and in different contexts (school, cinema, online game, Facebook) for example. It works the same in business, before someone can actually develop trust, which is not something you can accelerate there is an incompressible amount of time, frequency and context needed to build trust. That's why companies create content, politicians go on long form podcasts, and experts organize webinars. Some of it is 1 to 1 (private coaching, phone call, lunch, coffee break) , some of it can be leveraged 1 to many and in asymmetric ways. That's the power of : books, community, social media, workshops, podcasts ... Trust requires consistency :
So, what can you do about it ?Once you know your WHO, your avatar, your ideal customer profile, your buyer, your ideal employer. Ask yourself how can we create actions and content that increase that 3-part counter to get to 7-11-4 with each one in the most effective way. And it may be your Earned Trust Formula. Hours (H) | Frequency (F) | Touchpoints (T) Here's mine :
So, it looks like that even without the YouTube Masterclass, I have the environment to get beyond [7h | 11x | 4 places] So what are you doing to help people get exposed to your message, your expertise, your product ? |

Pick one. Anyone, but pick one. I learned from our cousins the “creatives” that my biggest obstacle to build a profitable service business lays in “my creativity” what ?? Entrepreneurial engineers are a form of creative entrepreneurs. We are so “curious” we can’t help but when facing several doors, we want to open every single one of them. It’s almost compulsive. Which curious mind can live with themselves leaving one stone unturned ? We proud ourselves into being “solution-oriented”,...
Unlike Professor X, we can't get into people's head and tell them what to do. But there's something else we can do. My first job as an avionics engineer was to update the embedded software of an Fighter's Electronic Warfare Equipment so it would store and manage data in FlashPROM instead of EEPROM. Sounds easy, just replace an electronic component with another, and boom it's done. Well, that system was an existing and robust one, built more than a few decades back, and I could not use all the...
We've created this amazing solution, how do we sell it ? As AI takes center stage, I’m seeing a flood of firms churning out “amazing solutions” for problems that might not even exist. 🤨 This made me think of Eric Ries's "The Lean Startup", when I read that book in my early years of avionics software development, and up to that point I lived under the impression that we were at the top technological advancement ... that's when it hit me. "No Othmane, you are working on a known solution, for a...
