US startups, agencies and enterprises come to GTS Infosoft to ship mobile apps, web platforms and AI products without carrying a domestic-only team. We have an office in Kirkland, Washington and a senior delivery studio in India — real US-hours coverage on one side, the offshore cost efficiency American buyers want on the other.
In 16 years we've delivered 250+ apps for 100+ clients across SaaS, on-demand, fintech, healthcare and IoT. We're also ISO 9001:2015 certified, which means US companies get documented processes, accountable project management and predictable delivery from day one.

Frequently Asked Questions
Can you work in US time zones?
Yes. Our Kirkland, Washington office gives us a real US presence, and the India team works overlapping hours, so you get live time across Pacific, Central and Eastern zones for standups, calls and reviews.
How will we communicate during the project?
You work with a fluent, English-speaking team and get direct access to your engineers and project lead over Slack, email, Zoom and shared boards. Regular written updates mean nothing gets lost in translation.
How does your pricing compare to US agencies?
Our blended offshore rates typically run at a fraction of US in-house or agency costs, and your project still gets senior talent. Estimates are clear and itemized, with no hidden fees.
How do you protect our IP and confidential data?
NDAs get signed before anything is shared. You receive full IP and source ownership, and we follow ISO 9001:2015 controls — secure repositories, access management — for the whole engagement.
