Bottleneck Marketing?
Bottleneck Marketing is a paid media and marketing analytics agency for startups.
We focus on identifying bottlenecks in paid channels and acquisition funnels that are holding back results and work to solve them.
It is run by Plínio Siqueira.
“We had strong momentum but lacked the structure to scale paid media effectively. Tracking was not reliable, results were inconsistent.
Working with Bottleneck Marketing helped us change that fast.
They brought clarity, focus, and a solid framework. We executed together. In just 55 days, revenue grew by 371% and ROAS improved by 29.5%. Now we are scaling with confidence.”
David Wiprächtiger, Co-Founder at oiwhite
Bottleneck Marketing is specially designed for startups that want to scale quickly and profitably.
We are not for founders who are just starting out or testing the waters.
You need to already have product-market fit.
In other words, you need a group of engaged customers who love your brand.
If you have that, we will help you find and bring in many more clients.
I, Plínio Siqueira, am a Production Engineer who graduated from the best university in Latin America.
There, I studied the Theory of Constraints, a method for identifying the point that most limits a system’s performance in factories (the bottlenecks).
I adapted this method to marketing and created Bottleneck Marketing.
There are hidden bottlenecks in your paid channels and acquisition funnel.
I identify and optimize these constraints to unlock exponential growth.
“Plinio was a great asset to our team – he helped us scale our signups via performance marketing by 4x in only 10 months. He is independent, thoughtful, and responsible. He’s versatile and can help get any team hit their objectives and grow their business.”
Christian Wicks, Co-Founder at Teero

“I met Plínio when we worked together at Dotz for the Vivo squad. It was an intense experience! Together, we conducted research using Tawk.to, shared references, and discussed every detail of the campaigns. Because that’s how Plínio is. He’s always striving to do more and better, with innovation and a sharp focus on results. He’s always learning, staying updated, and looking for ways we can improve.

“Since his first day at Favo, Plinio has been playing a key role for the company in several matters, such as a significant (and constant) improvement of business analytics and most important, bringing very good points to all discussions within the leadership squad. Always backed up by solid data and making recommendations for the next steps. I strongly recommend this guy to anyone looking for a top-performer, very data-oriented, and with rare technical skills regarding performance marketing. His learning skills are as well above-average and I do expect to work with him in another opportunity. He’s a rockstar.”
Felipe Macario, Head of Growth at Favo
“I had the pleasure of working with Plínio during my time in the partnership between Dotz and Pmweb. Plínio was a great leader, always assigning tasks in a very thoughtful way, keeping in mind how relevant the return of each activity would be. The requests were communicated clearly, and the inputs brought by the BI team were always heard and considered. We had full freedom to discuss and contribute to the planning. One of the most valuable deliveries we developed together was an end-to-end view for attributing results based on Google Analytics data. There were many exchanges and alignments, always ensuring expectations were met. But that is just one example. The number of valuable deliveries that came from this partnership was significant. It was a pleasure to be part of the Martech squad!”

“I’m very grateful to have worked with Plínio on the Growth team at Favo. In an early-stage startup, expansion is essential for success, and within a few months, the team achieved 1,000% growth in our main metric. Grateful because Plínio is a professional in every sense of the word. He played a crucial role in our expansion, multiplying our lead volume through his marketing campaigns, and in a short period of time, helped us reach new heights. In addition to being a specialist in his field, he cares about the team’s goals, contributes to key discussions, and consistently seeks to improve his skills. Plínio is a well-rounded professional. I highly recommend him.”
Franco Rocha, Operation Strategist at Favo
My name is Plínio Siqueira and I’m a digital marketer with over 5 years of experience. I’ve managed more than $1,000,000 in ad budget.
I doubled monthly ad conversions for 6 businesses, each over a 90-day period, while reducing customer acquisition cost.
How did I achieve that?
By applying the Bottleneck Marketing framework, a method I discovered by accident.
I graduated in engineering. I didn’t plan to be a marketer, but I had bills to pay.
So I took the first job I could find at a newly created digital marketing agency.
In my first week, my boss told me:
“If we don’t improve this client’s results this week, they’ll leave.”
It was our biggest client.
“If they leave, I’ll lose my job,” I thought.
I was desperate.
I knew nothing about digital marketing.
What was I supposed to do?
That is when I asked myself:
“What if digital marketing had bottlenecks?”
While studying Production Engineering, I read a terrific book called The Goal, which explains the Theory of Constraints.
It teaches how to find and optimize bottlenecks in a factory.
So I adapted the Theory of Constraints to digital marketing.
And it worked.
In one week, that client’s weekly ad revenue grew by 20%, and return on ad spend improved too.
The results only got better.
I started doubling conversions in 90 days while gaining efficiency.
My best result? I helped a startup more than 10x its main metric in 180 days while reducing customer acquisition cost.
I’ve applied the Bottleneck Marketing framework throughout my career, and it keeps producing amazing results.
That’s why I’m confident it can be a game-changer for your business too.
“As founders, we need to move fast, but moving fast without clarity was holding us back.
What made the difference was having a clear system. Once we had reliable data and a structured way to test, we stopped guessing and started growing.
It was not just about better numbers. It gave us confidence in every decision we made.”
