Our Story

Years of successful software development


Beginnings as the "Self Made" agency

The year 2020 marked the inception of our small yet ambitious software development company, which started out as "Self Made".

The company was founded by two friends who shared a passion for technology and a dream of creating meaningful solutions.
Despite the lack of resources and fundings, we set out to bring our vision to life. Starting from scratch, we had to be resourceful and adaptive in order to overcome the obstacles that came our way.

We leveraged innovation to bring our projects to life, and soon gained a reputation for delivering high-quality software solutions.

Rebranding to Deltologic and building a team

The following year, our company underwent a major changes, both in terms of its name and its team.

We changed the company's name from Self Made to Deltologic, signifying its evolution. Along with the rebranding, the company made its first hires and started building its team. This allowed us to expand our services and start cooperating with a wider range of clients, including many startups and Fortune 500 companies.

The team's combined expertise and drive allowed our company to quickly establish itself in the software development industry.

Niching down to marketplace solutions

The year 2022 was a time of growth and further specialization for our company. After successfully establishing ourselves as a software agency we began collaborating with universities and institutes to research the Amazon's algorithms.

Through these partnerships, our team was able to gain unique insights and know-how and decided decided to focus its efforts on a new niche: software and automations for Marketplace Sellers.

In addition to our new focus, we also continued to grow the team and expand our market reach, growing by over 200%.

Rapid growth and products development

As of 2023, we are already experiencing rapid growth and new beginnings. We have firmly established ourselves as leaders in the marketplace software industry and continue to build on our success by developing even more innovative custom solutions.

One of the key developments of 2023 is our push into developing our own Amazon software products. We design them to be affordable and accessible to everyone, while also offering advanced customization options. Our goal is to level the playing field and make top-notch software available to every Amazon seller, even if they can't afford to go with our fully custom solutions.

Global expansion and new technologies

As we look towards 2024 and beyond, we have set our sights on becoming the global go-to experts in the marketplace software industry and making our presence known in new global markets.

We want to expand our reach by further opening ourselves up to South America and Asia and developing even more solutions for Sellers on platforms such as Mercado Libre, Rakuten, and Tmall.

As we already see that AI has the potential to revolutionize the way businesses sell on marketplaces, we also aim to further develop our know-how in this field and implement it in our solutions.
