In summer 2025, the buying team behind a casino + sportsbook brand running on Phoenix365 in Argentina scaled its Facebook acquisition volume 55x in just two months.
Normally, growth at this pace puts serious pressure on the economics: auction costs rise, audiences become broader and less targeted, and repeat deposit rates decline. That didn’t happen here.
We break down why, using all four monthly cohorts from the scaling sprint.
When acquisition volume increases by tens of times, the cheapest high-intent audiences are the first to run out. Facebook auction costs rise, campaigns expand into broader and increasingly colder segments, traffic quality declines, repeat deposits fall, and payback periods get longer.
That’s why aggressive scaling usually comes at the expense of unit economics: you pay more to acquire a player who generates less value.
The goal of this sprint was the exact opposite: increase FTD volume by tens of times within a single quarter without sacrificing cohort quality.
Here’s what the numbers looked like:
| Monthly cohort metric | June 2025 | July 2025 | August 2025 | September 2025 |
|---|---|---|---|---|
| FTDs per month | 828 | 12 173 | 25 364 | 48 820 |
| Acquisition spend | $18 455 | $327 532 | $633 766 | $678 598 |
| Cost per FTD (CAC) | $22,3 | $24,9 | $23,0 | $13,9 |
| Deposits as % of spend, first 14 days | 104% | 77% | 79% | 82% |
| Repeat deposits per player, first 14 days | 2,01 | 1,97 | 1,83 | 1,70 |
| Payback period, months | 4 | 7 | 6 | 4 |
Methodology: monthly FTD cohorts. Primary acquisition channel: Facebook. Platform: Phoenix365. CAC is calculated as monthly spend divided by monthly FTDs.
Rapid Growth Didn’t Trigger a Cost Spike
Throughout the scaling period, acquisition costs stayed within the $22–27 range, including July, when monthly volume jumped 15x in a single month.
In other words, the sharp volume increase did not lead to a corresponding spike in acquisition costs.
By September, after three months of accumulating conversion data and iterating on creatives, CAC had fallen to $13.9 – 38% below the starting point – while monthly volume was at its highest.
The most counterintuitive part of the case is that scaling didn’t make players more expensive to acquire. It made them cheaper.
During the main scaling period, the average number of repeat deposits per player within the first 14 days declined by just 9%, from 2.01 to 1.83, despite the audience expanding several times over.
With September’s much broader audience, the figure predictably declined further to 1.70.
But acquisition costs fell faster than audience quality was diluted. As a result, even at peak scale, deposits generated during the first 14 days covered 82% of advertising spend.
The initial cohort generated deposits, or cash-in, equal to 104% of acquisition spend within the first two weeks and fully paid back on NGR within four months.
The peak September cohort also paid back within four months – the same timeframe as the much smaller starting cohort.
The intermediate cohorts from the scaling period paid back within six to seven months.
So by the end of the sprint, the highest-volume month was also one of the fastest to pay back.
Volume remained above 20,000 FTDs per month through the end of 2025, while September became the most efficient acquisition month of the year.
The scaling push didn’t exhaust the audience. Instead, it moved the project into a sustainable operating mode.
By the summer of 2026, the project was generating deposits equal to 100-107% of acquisition spend within the first 14 days, with CAC starting at $11.7.
The acquisition results are the team’s achievement.
The role of Phoenix365 was to ensure that everything after the click continued to work as volume increased:
Unlike most iGaming platforms that primarily provide access to software, Phoenix365 is built around a different principle: the operator remains in control of the business, the product, and the pace of development.
It is a B2B platform for casino and sports betting, developed entirely in-house. Casino, betting, and CRM are combined within a single ecosystem, alongside risk management, gamification, AI tools for player management, BI, and a flexible frontend.
Today, Phoenix365 has 62 brands live in production across most Latin American markets, including Brazil, as well as in Africa, Tier-1 markets, the CIS, and Asia.
Operators can launch within one week and turn unstable traffic into recurring depositors using solutions built by a CEO with 20 years of industry experience and C-level executives from major international B2C brands.
This case isn’t about cheap traffic, and it isn’t about a magic platform.
It’s the result of a strong buying team whose post-click funnel didn’t break under 55x growth: payments continued to go through, repeat deposits continued to come in, and fraud continued to be filtered out.
That’s what makes scaling manageable rather than a lottery.
