Sigmastocks was founded in 2014 by mathematicians and engineers as a reaction to high fees in mutual funds. The fintech company provides a tool based on mathematical algorithms and big data that makes it possible for individuals to invest in stocks without prior knowledge. Sigmastocks vision is to provide a long term, transparent, mathematical and fair tool for investment. The challenge was to develop a web application that makes investment in stocks easy and user friendly.

What we did

The project started with a workshop where users, technical framework, and challenges were identified. A roadmap with needed functionality and flow was produced from which Varvet crafted the initial prototype. Varvets developers and designers works in team to create user friendly web application with high technical standards.

Varvet are industry leaders within Ruby on Rails in Scandinavia, which was the chosen framework to develop the web application. The framework allows for customized web application development with iterative improvement. Together with Sigmastocks, we developed a system for handling customer data and for calculating the users monthly savings. The web application was integrated with Nordnet to make the buying process of stocks easier for the user. User tests were carried out to ensure the quality of the platform.


The product makes it possible for users to create their own portfolio by using Sigmastocks’ mathematical models. Sigmastocks were pleased with the collaboration with Varvet and we are proud to contribute to a change in the financial industry. The launch of the new platform increased the user base from 300 to 2500 paying customers (march 2017) and is growing with 20% per month. Varvets collaboration with Sigmastocks continues and we look forward to working with them on their continued journey.
