How did we built Elveo?

Elveo is born to help startup founders understand how they can drive success with their teams. To do this, we’ve tested many solutions: big data, IA, personality test and so on.
After 3 years of study, we’ve discovered that a behaviour analysis was the best option.

Why using a behaviour analysis?

We strongly believe that each individual is unique and evolutive. This is something that personality theories doesn’t understand since they try to put people in boxes. Furthermore, personality is like a picture : it doesn’t evolve but people does.
Without an evolutive analysis, you can’t tell if two people will match on the long term. That’s why we decided to seek for behaviours which is more profound and less superficial than personality.

Behaviours evolves and that’s the reason why founding teams may have issues on the long run. Working in a startup is a lot of stress and stress change us. Partnering is similar to a couple and the evolution of behaviours are key to any relationship.

We’ve chosen behaviours over everything else since they’re at the heart of who we are. Behaviours drive our motivation, dedication, passions, values… Understanding them is essential to know which kind of startup a founder will make.
Apple weren’t so obsessed with details if it wasn’t Steve Jobs which was personally passionated about details. Same thing with Mc Donald’s, if the company weren’t handled by Ray Kroc, the company weren’t that’s efficient and efficiency is part of Ray Kroc entrepreneurial style…

Everything starts with people, understand them and you will build outstanding companies.

How did we built the questionnaire? 

Founding psychological theory: Carl Jung 

The initial theory behind our tools comes from Carl Jung, a psychologist from the 50’s which was the first to draw the lines of psychological types. He’s theory works around 8 cognitive functions which are used in a different order by each of us. This difference explains why we all act in a different manner: we don’t have the same priorities and talents.

In the late 60’s, Myers Briggs added the extraverted and introverted aspect into Jung theory, creating the MBTI, still known today. Since then, Carl Jung theory is at the heart of many common HR models: DiSC, interaction styles, MBTI etc.

Latest evolutions of the theory: neuroscience

Since then, a lot of progress has been made in psychological typing. Thanks to John Beebe and Linda Berens research, we’re now able to understand the evolution for each of the 8 cognitive functions from Jung. The way you are today will evolve and we can understand which path you will take, which difficulties you may have and what can stress you along the way.
This evolutive understanding is made possible thanks to neuroscience. Dario Nardi, researcher at UCLA in neurology, have proven the link between Carl Jung 8 cognitive functions and the different area in the brain (study available here). For each of the 8 cognitive functions, some “zones” in the brain are more or less interconnected.

According to your envrionnement, age and life experience, some zone will develop progressively. By using ECG to map the brain activity, researchers has been able to theorise in which way and at which pace, each psychological types may develop their 8 cognitive functions.

Asking the unconscious: the questionnaire

Using verified models is key, but the difficulty remains in the way you assess these behaviours.

The Elveo questionnaire isn’t about opinion. We don’t ask what you think about something because your opinion is likely to change after a few months.

Instead, following Dario Nardi theory, we’ve built questions that are appealing for the unconscious. Accordingly to your type, your unconscious will recognise patterns that he like and choose them.
For example, people with strong vision will like words like : imagining, knowing or divining. Naturally, people with strong vision will recognise these patterns and choose them.
Because of this, some sentences will look like incomprehensible since it’s not a pattern we use and recognise. The words aren’t appealing for the unconscious and the person doesn’t understand what it is about.
Of course, this process is unconscious and your brain respond almost naturally since it’s pleasing for him. It’s like an icecream for the mind, if the mind like these kind of words, he will choose them naturally.

The evolutive analysis identified in 15 minutes what we’ve identified after 2 years working together. Nicolas, founder

To be sure our questions aren’t biased, we’ve evaluated the effect of each question on people’s brain “zones”. To do this, we’ve used ECG and heart rate monitor to understand how the brain react for each words and patterns according to people psychological functions. By iterations we’ve created the questionnaire. This concept was first introduced by Dario Nardi in 2007.

Validating our model

Validation is key to use psychological tools. During this research phase, we’ve worked with psychologists and HR specialists to test our model on different typology of populations : students, workers and startup founders.

We’ve then observed how successful people works together to build our matching tool and tested it with more than 500 entrepreneurs, successful and less successful, to train our model. Some of these teams worked for more than 20 years together and helped us understand which behaviours where essentials to their success.

Finally, we’ve used our model with early stage funds and their startups to create meaningful and easy to use reports. We’re now working with certified coach to help founders and investors with our model.

founders tested to build Elveo


of our clients recommend using Elveo

To summarize, our model is based on the following elements

  1. Carl Jung verified models which are used in many recruitements tools
  2. Understanding people evolution, since startup founders will evolve a lot
  3. Using an unbiased assessment, to get real insights about people and not only how they perceive themselves
