Want to build a unique marketplace business?

When building your next unicorn, OQTACORE recommends building a marketplace from scratch instead of using eCommerce content management systems (CMS). Why?


Most conventional eCommerce platforms have restrictions with respect to integrations and content. If you have an inspiring vision of your future unique product, we can help you unleash the full potential of your business.


Based on your business needs, you’re completely free to select what features to be implemented and how.

Total Control

Having your own solution built from scratch gives you the freedom and flexibility that come with full ownership of your business. This ensures you’re the final decision-maker on how your platform runs.


Each CMS has its internal mechanics that can become a problem in the later stages of the project. Fixing them will break compatibility with future CMS updates. Having your own code gives you a full understanding of what will and won’t work instead of having to scout numerous community forums.

Why choose
OQTACORE for your
development needs

Your project needs to have maximum traction right before the start of the investment round to get the maximum valuation and interest of investors. The count of active customers values startups at the time of the deal.

We see the best results when founders spend equal amounts on development and advertising (50/50).

If you do not have free ‘unfair’ advertising channels like friend celebrities, your own TV show, etc. OQTACORE does not take projects where development consumes more than 70% of the total investment.

Every IT company is 30-50% about its software, and 50-70% of the business success is about execution.

OQTACORE’s company culture has a concept of “Execution culture”:

  • 1. Never overpromise;
  • 2. Everything that is said to be done - must be done.

All our employees are constantly reminded not to overpromise to their managers. And we as a company do not overpromise to our customers. Since we always do what we promise, you can trust every word we commit. That is why OQTACORE is such a reliable partner, even though we might promise less than many of the dev shops.

Being trusted is extremely important for OQTACORE’s business model, as we only benefit from long-lasting relationships.

Before starting development, OQTACORE always conducts in-depth analysis and competitive intelligence: target audience interviews, legal research, and competitor analysis by 60 parameters.

This allows us to come up with our vision of business model (transaction fees, tech spending, royalty model, CPA, LTv, etc), development roadmap, and offer the best tech decisions: choose the right cloud platform, tech stack, etc.

We are different from other dev shops. The OQTACORE team will not come back to you with an echo of your words when asked to improvise. We know how to fill in blank spaces in the global vision of a startup founder.

You can focus on achieving the right vision for your business development while we take care of billing, payment systems, account management, support systems, and other routine subsystems that exist in any software product.

It is up to you to decide whether you want to control the implementation of standard features or completely trust it to OQTACORE.

If you are a visionary startup founder, you may have a $20m idea that cannot be built with a $500k investment.

If you do not have a technical co-founder, it might be hard for you to understand what can or cannot be implemented in the short term and with a tight budget.

OQTACORE will do the heavy lifting for you. We at OQTACORE have experience working with such cases. Together as a team, we come up with a bootstrapped version of your idea. In the beginning, it might look small compared to your vision, but it will get traction and move forward into the investment rounds until you reach the full potential of the product.

Steps of developing an
online marketplace with

Either before the first consultation or immediately after it, we will sign an NDA so that we can ask and find out details that are important for the project, which may constitute a trade secret.
At the initial consultation, you can get to know the leaders of our team, and we, in turn, will get to know your product, its current needs, and goals.
We conduct market research and competitor analysis, focus on customers' experiences, and analyze trends and best practices. Then we come up with solutions and decisions that will empower your product for success. You can choose to accept or not accept each individual proposition.
Based on your vision and decisions taken, we estimate the scope of work, the timing, and the cost, and come up with a commercial offer.
​​If you are satisfied with our offer, we will ask for a 33% prepayment and get down to work.
We usually break product development work into two-week sprints that minimize the amount of up-front planning. We always prioritize items in the backlog at the beginning of each sprint. Thereafter, our development team starts building the required functionality, which is then tested against bugs by our QA engineers before release.

OQTACORE was recommended by one of our partner companies. We worked with many development companies for comparison. The best part of a partnership with the OQTACORE team is that in addition to exceptional quality specialists, the founders Dmitriy and Saveliy, take care of all the details and let me focus on strategic thinking. I give them the main direction and they tackle how the product should look and feel. The quality of their specialists and the price that we are paying for that quality is fair.

The OQTACORE team built for me a web phycological freelance platform that brings together psychologists and clients. On this platform, they can call each other, chat, schedule appointments, and so on. This is a huge project that we are working on right now. OQTACORE shows a very high level of quality. I really like the management - we are always on the same page. We often have phone calls on weekends if I need them. We started small, and it is important that OQTACORE has used a scalable architecture for future growth since we expect hundreds of thousands of users in the coming years. I am also planning to create an application with them for iOS and Android.
