The Partner

Bloomreach’s data engine unifies real-time customer and product data so businesses understand what customers really want. By connecting that understanding to every channel, the e-commerce experience becomes limitless — reflecting a changing customer as they shop. Amplified by the speed and scale of Loomi, Bloomreach’s AI for e-commerce, this creates endless new paths to purchase, greater profitability, and fast business growth.

Bloomreach products include: Engagement, a marketing automation platform; Discovery, an e-commerce search solution; Content, a headless CMS; and Clarity, AI-powered conversational shopping. The company has multiple AI patents and serves 1,400+ global brands including: Williams-Sonoma, Bosch, Puma, and Marks & Spencer.

Our partnership started in 2019 with Exponea, a growing scale-up that was acquired by Bloomreach in 2021. Exponea’s leading CDXP platform has since become the core Bloomreach product and is the no. 1 choice for 1000+ data-driven marketers, powering 250 million searches daily.

The Mission

Bloomreach customers get intelligent and actionable insights through their cutting-edge analytical platform. Much of this wouldn’t be possible without reliable data collection mechanisms Panaxeo implements into Bloomreach’s mobile SDKs. These are integrated into customers’ Android and iOS applications to collect real-time data and enable campaign features such as dynamic in-app messages.

Having started our partnership in mid-2019, Panaxeo engineers assess, redesign and rebuild the data collection SDKs to enable simple, fail-proof and performant integration into any iOS or Android mobile application on the market. We started with 3 mobile SDKs, growing into 5 SDKs in 2024 (Android, iOS, React Native, Flutter and MAUI).

During our cooperation, functional features like the app inbox and in-app messages have joined data collection, turning Bloomreach SDKs into all-in-one packages.

Bloomreach’s userbase grew to
96 million monthly active users
over the course of our partnership.

We’re maintaining a growing number of technologies and platforms for more SDKs while pumping out new features.

Key Improvements.

Selection of improvements we have introduced so far.

Advanced SDK monitoring that integrators can’t see

As the SDKs are processing tons of data, it’s crucial to know if something fails so we can act on it. This is achieved through advanced monitoring capabilities we baked into the SDKs.

The real challenge lies in providing these capabilities without interfering with any of the host application’s monitoring tools. As we believe SDK monitoring should be fully “invisible” to the integrators, we had to pull off some advanced techniques to achieve this, like building our own monitoring engine.

App Inbox introduced in 2023

Why should push notifications and in-app messages disappear once dismissed? Why not store them in an inbox for a defined period of time?

That’s precisely what the App Inbox feature we helped Bloomreach build in 2023 does. It makes mobile marketing that much stronger and a more vital part of the overall marketing strategy for Bloomreach’s customers.

It’s all very simple too. The users only need to add a button to their app’s screen. That button then displays all the messages. It’s all tracked, of course, and can be customized to your heart’s content.

Taking stability to the next level

We believe that the SDKs should run flawlessly in any environment, device and host application imaginable. With every new version of the SDKs we are introducing new ways to further act on that goal.

Most are beyond the usual, like careful thread isolation, future code testing or advanced error interception. All of this is done with a single goal – to further our mission to make the Bloomreach SDKs the most loved analytical integration on the market.

In-App Personalisation
is a must

In-app content blocks

Another feature we’re proud to have worked on is these sleek content blocks. They provide a seamless and unobtrusive way of displaying content. One more way for Bloomreach’s customers to display their campaigns!

The user can strategically place them where needed. Once set up, there is no further need for development involvement.

In-app messages

Should the SDK users need something more in-your-face that demands immediate attention, In-App Messages are their friend. They are fully customizable and assembled from native and HTML components. So they not only work great, but also look and feel beautiful to the user.

We took special care to make the integration as simple as ABC; saving integrators valuable time and development costs.
