As the leading provider of online trading services in the US, Gain Capital came to us with a rich legacy of success already in place. Counting innovation and digitization among their core values, the organization needed to modernize their IT system to maximize flexibility and keep up with customer demand. The project was a massive and exciting undertaking, and they knew having a reliable engineering partner on board would be paramount.

 Backed by strong trading expertise, our mobile engineers joined Gain Capital’s in-house team to build native iOS and Android applications for the brand, entrusted to make all crucial architecture and tool choices as well as execute them.

Impressed by their now-faultless mobile performance, Gain Capital then re-engaged us to revamp their flagging web solution, which was rapidly falling behind the times. Adhering to an ambitious timeline, we delivered a product that operated at the highest speed and functional trading standard, easily sustaining up to twenty million inquiries every day. 

Along the way, we implemented test automation and Salesforce best practices. Our bespoke QA framework not only enabled agile testing at scale, but saved an average of 64 days of testing per release; meanwhile, we 100% automated the process of assigning accounts and marketing consultants using Salesforce.


Thanks to our highly scalable approach, Gain Capital was able to expand their product offering and global reach, now serving 140,000+ retail and institutional investors across 180 countries and 12,500 OTC and exchange-traded markets. 

Today, iTechArt continues to fine-tune existing software solutions for Gain Capital as well as one of its acquisitions, spread betting platform City Index.
