We design simplest solutions to your complex problems


Theta One in the language of Computer Science means Theta of Order 1 which in turn means Lowest Order Time Complexity. That is exactly what our mission is – To create fastest solutions which are robust, scalable as well as customizable.
In short – we love playing around with the newest technologies and play it really well!

Good People

Your baby is in safe hands. You take care of the business, handling the complexity of technology is on us.

Refreshing Design

We believe in simplicity in design. As they say - "True genius lies in simplicity"

Robust Backend

We deploy the core business logic in really robust and scalable backend so that it never fails.

Crafted Carefully

The technology stacks are woven with care so that they work in harmony.


Here are the things we offer.

Web Application

We craft websites with refreshing and fluid front end along with a scalable backend.

Mobile Application (native and hybrid)

We also develop mobile applications across varied complexities. Our team is equally proficient with both Hybrid and Native apps. Hybrid apps are faster to develop but offer limited interaction with the device whereas native apps provides better touch and feel performance but takes bit higher time to develop than hybrid ones.

Artificial Intelligence

We develop AI powered applications to make your business process smarter. We use tools like Google Tensorflow to train and model the system according to your business domain.

Internet of Things

Our In-house tool Live Buzz is capable of interchanging IoT messages between machines in realtime. We develop IoT solutions for the problems having minimal hardware requirement based on the Live Buzz backend.


We work on cutting edge tech so that your business always stays ahead of your competitors.
