The Leaders Who Understand Their Own Psychology Operate Differently Than Everyone Else.
After 20 years coaching Fortune 500 executives, Dr. Dave Popple built a methodology that transforms how leaders make decisions, handle conflict, and show up under pressure. Now we’re making it accessible to everyone — starting with 500 founding members.

The pattern is always the same: intelligent, capable people get stuck because they cannot see their own patterns.
You’re Smart Enough.You’re Working Hard Enough.You’re Still Stuck.
The same frustration keeps surfacing in meetings. The same conversations keep going sideways. The same patterns keep repeating, and you can’t figure out why.
It’s not about effort or intelligence. There are patterns running beneath your decisions and reactions that you cannot see from the inside, no matter how reflective you are. Professional coaching reveals them. That’s why it works.
But high-quality coaching costs $500 – $1,500 per hour.
Most professionals will never receive it.
The methodology that produces results isn’t secret. It’s been expensive. We’re changing that.How does Telleus differ from what you’ve tried?
Understand Your Patterns.Change Your Outcomes.
ChatGPT gave you leverage over information. Telleus gives you leverage over yourself.
You prepare differently.
Before a high-stakes conversation, you know which of your patterns will activate and why. Instead of rehearsing what to say, you understand what’s going to happen inside your head when the pressure hits.
You stop having the same conflict twice.
Your conflict style interacts with other people’s in predictable ways. Once you see the mechanics, you change your approach instead of just trying harder with the same one.
The compound effect kicks in.
Every pattern you recognize makes the next one easier to spot. Your self-awareness compounds over time, and each situation becomes an opportunity to operate deliberately instead of reactively.
This isn’t a feature list. It’s a fundamentally different way of operating.
Most professionals won’t have access to it for years. The Founding Circle gets it first.
See how we compareHow Telleus Gets You There.
Telleus starts where effective coaching starts: with validated psychological measurement.
Not a personality quiz. Not a chatbot asking how you feel.
A comprehensive assessment of how you actually think, decide, and respond under pressure — the same depth of evaluation Dr. Popple developed through 20+ years of Fortune 500 executive coaching and 14,000 hours of collecting data.
Persistent Profile
From that foundation, we build a persistent psychological profile — a comprehensive model of how you actually function that informs every coaching interaction.
It Learns
The system doesn’t reset. It doesn’t forget. It learns and evolves as you grow.
Truly Personalized
Two people with the same concern often require fundamentally different guidance because their underlying psychology differs.
Treating people as unique is what makes executive coaching effective. Until now, the only way to access it was one hour at a time, at executive rates.

"Assessment makes the invisible visible."
“I’ve spent nearly two decades in rooms with Fortune 500 executives, Wall Street traders, and high-performing leaders who hit invisible walls.
The pattern is always the same: intelligent, capable people get stuck because they cannot see their own patterns.
They repeat the same dynamics in every role. They sabotage themselves at critical moments without understanding why. The patterns are often apparent to outside observers — completely invisible to the people living them.
I created an assessment to make the invisible visible. That’s when change becomes possible.
Telleus Assessments measure factors that predict professional effectiveness and effectiveness in life. It’s a tool that goes beyond personality “types”, to the specific elements that determine how you handle conflict, make decisions, relate to authority, and explain outcomes to yourself.
I’ve been the executive coach in the room. I know what produces results.
Now we’re building the technology because you deserve to be in that room.”

On the assessments powering Telleus
I have no idea how it knew me that well just from moving a few cards around.
I was nervous about meeting Dr. Dave, but the perspective he offered turned my career around.
It was not until I quizzed Dr. Dave for 2 hours on how the assessment was built that I truly understood how deep it goes and how accurate it can be.
It’s like it peered into my soul.
Questions & Answers
Generic AI has no model of your psychology. It gives everyone similar advice. Telleus begins with a validated assessment — then calibrates all coaching to your specific patterns.
90-120 minutes total, with pause/resume capability. This is comprehensive by design — the same depth Fortune 500 executives receive.
No. Telleus provides professional development coaching and life guidance, not clinical treatment. We'll always recommend appropriate professional support when needed.
Founding Circle members receive access in waves as we launch. Earlier waitlist position = earlier access.
Founding Circle members will secure pricing at a fraction of traditional executive coaching rates. We'll share specific tiers with the waitlist before public launch.
The Advantage
Shouldn’t Depend on Title or Budget
The patterns that limit professional effectiveness show up everywhere — in how you handle conflict, make decisions, relate to authority, and explain outcomes to yourself.
Until now, understanding those patterns required years of clinical work or an executive coaching budget most people don’t have. Professional development works. The methodology is proven. Before now, the only question was access.
Now there’s another option.
