Year 1: SDR at an L&D SaaS.
Year 2: SDR in cybersecurity.

Different logo, same disease -> activity worship.
Spam more. Call more. Measure motion, not outcome.

I watched teams confuse chaos with growth.
Marketing blamed Sales. Sales blamed “bad leads.”
Everyone built walls, then wondered why nothing scaled.

So in Year 3, I did what any sane person would do...I left the asylum.
Joined five builders I met on LinkedIn and started over.
No templates. No outreach quotas. Just systems.
Systems that turn attention → conversations → revenue.

That became Allbound: one GTM engine where inbound, outbound, content, ads and automation operate to achieve the same goal.

At Earleads, that operating model has generated 1,500+ qualified calls and $15M+ in pipeline for early-stage and scaling B2B teams.

Always happy to chat.

I’m the founder/CEO of Lebesgue — a group of data science experts specialized in the online growth field. We’re focused on building mathematical models that make your growth scalable and profitable.

We help start-ups analyze and improve their user churn, lower retention, increase product lifetime values (LTV) and a website’s average-order-value (AOV). We also scale advertising performance to improve low return-on-ad spends and return-on-investment (ROAS/ROI). The main questions we tackle are: Can your growth curve improve? Is your growth scalable? What do you need to do to achieve exponential growth?

Presently we work with successful startups like Dropps, Plume, OptimoRoute, RaeWellness.

Results we’ve achieved so far:
— 2 apps hitting #1 in the US app store
— Growing website traffic from 50k visitors to over 1M visitors monthly with paid advertising (profitable with the overall return on ads spent around 200%)
— Growing and managing the biggest European Facebook and Pinterest ad accounts
— Building a mathematical model that improved user LTV by over 30%
— Reducing churn and improving retention on apps with over 1M users

Check us out on www.lebesgue.io.

Besides Lebesgue, I have a Master of Science in Applied Mathematics, and I’ve been working on applying mathematical models in physics and computer science. Currently I’m trying to fit that knowledge in the online advertising/e-commerce field.

My interests span from game theory and its application in online auction systems to machine learning, statistics, and behavioral economics.

eTail™ Palm Springs was a special one.

Extremely thoughtful conversations, not just about marketing, AI, and agentic commerce, but also about life, travel, family, and building companies.

What stood out to me most?
In the age of AI hype, people crave something simple: concrete, human, actionable thinking.

On stage, what resonated wasn’t “AI is changing everything.”
It was showing where AI can go wrong.
How it can quietly bring performance down.
How high ROAS can hide weak growth.
How creative can start looking the same.

My main takeaway – and something we repeated on stage:
Use AI to challenge your ideas, not amplify them.

Really enjoyed sharing the stage with Davide Mattucci and Olivia Hnatyshin, and big credit to Renee Skower for thoughtful questions that sparked a great discussion. 

We’ll be sharing some of the more actionable insights next week.

More on that soon.

The Lebesgue team will be at eTail Palm Springs next week (Feb 23–26).

I’ll be joining the panel, “When Nerds Meet Creatives: Achieving Excellence Through Data and Marketing Team Collaboration.”

Modern marketing requires both creative instinct and mathematical rigor. But those teams often operate in parallel – optimizing for different signals and speaking different languages.

We’ll explore how to build shared frameworks where data informs creativity early, attribution supports better decisions, and collaboration becomes structural rather than accidental.

Looking forward to sharing the stage with Davide Mattucci, Melissa Feeney, Olivia Hnatyshin, Kristie Bidlake and James Kim.

If you’re attending, let’s connect.
