A fresh approach to teeth whitening, made in Brazil.
oiwhite is an oral care brand focused on at-home teeth whitening, founded in 2023.
When we met, the company was at the pre-seed stage, focused on early growth.
They were full of potential.
But like many fast-moving startups in brand building phase, they faced two common challenges:
- Tracking was not clear
- Paid media efforts were not scaling consistently
Wanting to speed up acquisition, every day counted, but without clear attribution and structure, it was hard to know the path to scale with confidence.
They had the right team, energy, and product.
They just needed the right framework to turn that momentum into sustainable performance.
After working together, oiwhite had a solid foundation to grow profitably:
- Tracking was optimized, giving a more accurate visibility of performance
- Bottlenecks were identified, allowing us to prioritize our tasks effectively
- A consistent testing routine was in place, helping us make smarter decisions, faster
- Benchmarks were used to guide smarter tests, aligning efforts with proven patterns
As a result, in just 55 days:
- Revenue increased by 371%
- ROAS improved by 29.5%
With the right structure in place, oiwhite could now scale paid media with confidence.
graph information
ROAS means Return on Ad Spend.
Formula is below:
ROAS = Revenue/(Ad Cost)
Before: the average Revenue and ROAS of the 3 months prior to any engagement with Bottleneck Marketing (Jan/25 to Mar/25).
Tracking project: before starting our paid media partnership, we did a tracking project and some performance meetings, which already improved results.
Paid media partnership: the partnership started on May 1, 2025, and lasted 55 days.
Important note 1:
oiwhite decided not to share absolute numbers, but they were happy to share the evolution.
That’s why we’re using the “Before” period as 100%. This means that 100% is the average of the three months in the Before period, both for Revenue and ROAS.
Important note 2:
The month Jun/25 compares the last 31 days of the partnership (May 25, 2025 to Jun 24, 2025) with Before (the average of the 3 months prior to any engagement with Bottleneck Marketing).”
“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
“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.”
