Lumos Apps

The Challenge

One of the current challenges and goals for Lumos Apps is to expand their publishing model even further, attracting more apps from more verticals — they’re currently aiming to add 30-50 more apps to their suite. At the same time, the scale of the operation has already grown rapidly. Lumos Apps run hundreds of campaigns per app in more than 50 different countries, leverage influencer marketing, and work SANs as well as gaming networks, meaning a lot of resources are needed to remain agile and to optimize effectively. When scaling an app, it’s crucial to be extremely reactive when it comes to UA. Accurate forecasting of app LTV is another key challenge when scaling, and is a north star metric for all apps in the Lumos Apps family. This has also become more relevant than ever in light of Apple’s changes to user privacy and working with SKAdNetwork.

In short, the Lumos Apps team were seeking assistance in multiple focus areas:

  • Scaling their operations and scaling apps internationally
  • Working with SKAdNetwork data and predict the future value of users
  • Matching data between different sources and finding out which data is accurate

This is why the team needed a very reliable and accurate MMP and data provider.

“I have been in the industry for 10 years now, so I know the different MMPs on the market. Lumos is extremely data-driven, every decision we make is based on data. Our ability to use data to forecast the future LTV of users and quickly change marketing campaigns based on this forecast is our strength. We can’t work without reliable data. In this context, the choice of the MMP is a very strategic one. We tested different platforms and it appears Adjust is the most reliable in terms of data.”

The Solution

Lumos Apps have built technologies that, with the help of Adjust, allow for complete automation of all campaigns. They’re now able to forecast LTV, calculate ROAS for each campaign (including SKadNetwork campaigns), and can automatically change the bids and budgets as quickly as needed. This has made a crucial difference to their international scaling efforts.

The team also realized the need for a single source of truth, as when you’re working with a multitude of tools, it doesn’t take long to realize that the numbers often don’t add up. With Adjust, they’re easily able to match the data between different sources and determine the numbers that are accurate. This reliability and data accuracy for LTV forecasting and strategic marketing decision making is one of the key benefits the team has found from working with Adjust.

Adjust’s iOS 14.5+ solutions were another differentiator when choosing an MMP. By working with the Adjust team to integrate their tools for optimal performance and compatibility with SKAdNetwork, Lumos Apps have been able to continue successfully working on the iOS platform thanks to the side-by-side data and reporting provided by Adjust.

The most challenging part of working with SKAdNetwork for the team so far has been finding the ideal conversion value schema that can be used across different apps in their portfolio to deliver a precise LTV forecast based on first usage of the given app. The team is still improving this forecasting, but has seen highly promising results so far. They work continuously with their data team to identify the key events that take place in a user’s first session, isolating those that have an impact on revenue, and ultimately including them in their conversion value schema.

"I am satisfied with Adjust’s iOS solutions because there is also really good communication between the Adjust team and our tech team. We quickly reached good solutions together. Yesterday it was iOS 14 and tomorrow there will be something else, but we can work together to face the next challenges.”

The Results

In a matter of months, Lumos Apps reached the top positions on the App Store charts. Weburn made it to the top 10 in the U.S., Bend to the top 50, and Plaw to the top 10. Using the Lumos publishing platform and Adjust, hundreds of bids and budget changes are done on a daily basis, which has led to a profitability increase of 5x. Lumos is now working on more than 10 new apps and is growing rapidly.

Lumos Apps efforts with Adjust have resulted in:

  • Lumos Apps reached the top positions on the App Store charts
  • Profitability increase of 5x

"The data architecture of Adjust is very convenient for a company like ours. Everything goes into our BI system and the data is refreshed on an hourly basis. We believe it reacts extremely quickly. Both the tools and the ability to react within an hour is very convenient and appreciated.”
