“8 Years of partnering with Insider One to drive double- digit uplift in flight search and ancillaries through large scale A/B testing and personalization at our org”

5.0

May 15, 2026

Our overall experience with Insider One over the past 8 years has been very positive, and the platform has evolved alongside our digital ambitions. What has worked particularly well is the combinations and real-time segmentation, which allows us to continously optimize booking and ancillary journeys and clearly meansure impact on KPIs like flights search and incremental revenue. The main challenge is the breadth of functionality - new users can be overwelmed at first but long-tearm, the depth of capbilities has been a key reason we've continued the partnership for 8 years.

Performance of Insider One Across Market Features

Insider One Likes & Dislikes

- Mature A/B and multivariate testing that we have relied on for 8 years to validate changes and automatically send more traffic to the winning variant for faster conversion uplift. - Powerful segmentation and targeting including location-based rules, enabling our org to dynamically highlight the most revevant departure airports and offers for each traveler. - Robust analytics and reporting that clearly attribute uplift from each experiment and campaign, so our teams can quantify incremental flight searches ancillary revenue and ROI from our long-term testing program.

The best about Insider is technical and customer success support

The platform's user-friendly interface and no-code templates are what I like most. It empowers our marketing team to launch sophisticated campaigns independently without being a burden on our IT department. This agility is crucial in the fast-paced banking sector, allowing us to react to market trends almost instantly. Also, the dedicated support team is exceptionally proactive in helping us reach our KPIs.

- The wide feature set can make the interface feel complex for new users who only need basic testing at first. - Frequent product updates mean we need regular enablement to stay on top of new features and make the most of them. - Some of the most advanced journey and experimentation setups still require close collaboration with Insider's experts initially, which adds a dependency before our internal teams are fully up to speed.

The instability of the platform and non flexibility of the platform

The platform is so feature-rich that the initial learning curve can be a bit steep for new users. While the interface is intuitive, mastering the more advanced predictive tools and complex journey logic requires dedicated time and training to fully unlock the platform's potential.

Feature-Rich Platform Enables Fast Campaign Deployment Despite Steep Learning Curve

May 7, 2026

Insider One has significantly improved our marketing agility. We can now deploy hyper-personalized campaigns in a fraction of the time it used to take. For a participation bank like ours, the ability to segment users accurately and provide relevant financial offers has directly translated into higher conversion rates and better customer retention.

Delivering Scalable Personalization with Unified Data and AI-Driven Insights

Apr 21, 2026

Our overall experience was very positive. Insider One team behaves like a partner rather than a supplier. They share category benchmarks, plan campaigns and respond quickly. For a brand like ours, where every touchpoint needs to feel considered, having one platform that handles data unification, AI personalization, and cross-channel orchestration has been the right call.

They're solving the personalization problem. We've never had marketing where we could target the right user at the right time; Insider One allows us to do that. We're also very invested in omni-channel and integrating with our current in-house architecture. That has proved to be a challenge Insider One is up for and, despite challenges and setbacks on both sides, we've always been able to come through with a workable solution. Many of the issues have been caused by our internal set up so we're barely coming out of the implementation phase, but we have a clear path forward and anticipate getting more defined results soon.
