David Phillipson

CEO & Co-Founder, Dataseat

We were looking for an experienced vendor to develop a performance-based media buying solution from scratch. One of the main reasons why we chose Xenoss was their extensive domain knowledge. It allowed us to save time and effort at the initial stages and dive right in product development. The team’s been very professional and responsive to our needs and was able to deliver the MVP under just several months. Later on, they’ve transformed it into a fully featured platform for in-game advertising, which already proved highly scalable and able to manage high load. I’ve been truly happy with their work, high quality standards, and communication.

VP of Product, Powerlinks

Before turning to Xenoss, we had a demand-side platform that was costly and not scalable. Having access to a wealth of experience on the Xenoss team related to our domain of real-time bidding, we’ve cut costs and now have a much more efficient, reliable DSP for our customers. I’d gladly recommend Xenoss as a technology partner. I’ve found the team to be very professional and diligent, ensuring that our needs and expectations are met through every step of the development process.

At some point of our business journey, we had a frustrating experience with our product, from barely managing its instability to fixing errors on the fly. Xenoss team helped us build a well-balanced tech organization and deliver the MVP within a very short timeline. It let us timely onboard huge clients such as Adidas, Tesco, Uber and keep up our growing pace. I’m glad we’ve been working with such highly-productive team. I particularly appreciate their ability to hire extremely fast and to generate great product ideas and improvements.

OUR
WORK

Fast Delivery of Complex AI-based MarTech Solution

MarTech | Ad creative management platform

The client looked to create a huge and complex AI-based system for top global brands. It would help advertisers to automate the process of ad creative development and management. Despite the enormous initial scope, we delivered the expected MVP in only 4 months. This allowed the client to start aggressive sales activities and acquire customers so early in the product development cycle. By keeping on with frequent releases, our team ensured a successful product evolution. Ad-Lib is now being used by such giants as Tesco, Adidas, Nestle, and others.

3.7x Bid Rate Increase through Building Pretargeting Functionality

AdTech | Video ad network and SSP

Viewster SSP came to us when their connected DSPs had the bid rate lower than the industry average, which led to an unbalanced revenue-to-cost ratio for the client. After a careful audit, we determined the root cause in buyers receiving irrelevant traffic they never bid on. To solve the problem, we designed and developed sophisticated dynamic pretargeting functionality that filtered out irrelevant traffic for DSPs in advance, and subsequently raised the bid by 3.7 times.

4x Reduction in Traffic Costs for Video Intelligence SSP

AdTech | SSP

The client turned to us when traffic costs skyrocketed to make 50% of infrastructure costs. We conducted a thorough statistics analysis to find out the issues causing this problem. After getting results, we implemented traffic compression algorithm of the RTB requests over HTTP protocol and created a smart auction subsystem, aimed to select optimal DSP list for each ad opportunity. As a result, traffic costs decreased by 4 times, hardware costs plummeted by 68%, and the average number of bidders dropped from 19 to 4.
