Databook
With Databook we worked on completely rewriting their customer-facing platform from AngularJS to the new modern React architecture.
Databook Enterprise Customer Intelligence Platform (ECIP) is a secure, cloud-based application that continuously curates data for the world's largest companies to deliver real-time insights and personalized recommendations about customers and prospects.

dobartek.hr
We have developed, scaled, and maintained this online food delivery platform. It has grown into a profitable company, with sales, customer support, and marketing departments, serving 70.000+ users and 130+ restaurants, growing in revenue every month.
What started as a simple web app has grown into a leading food ordering platform in Croatia with a focus on the best UX available on the web, Android and iOS platforms.

Bitcoin Store
An online Crypto to Crypto and Crypto to FIAT exchange and a back office system for physical exchange stores in Croatia.
We built the product from scratch and worked on all development lifecycle steps from product design, UX design, software development, QA and maintenance.
The system is delicate because of its integrations with other Crypto exchanges (Bitstamp, Binance, Bitfinex) where it performs live trades every second. We worked a lot on the system optimization and security. The main goal was to make the system stable, efficient and bug proof in order to generate maximum profit out of each trade.

Bitkonan
First Croatian cryptocurrency trading platform for Bitcoin, Litecoin and Ethereum.
We upgraded the first basic version of the exchange to more robust infrastructure and much better UI and UX. A lot of back office improvements were made including automated deposits and withdrawals of FIAT (USD) where we had to make an integration with our bank system.
Trading engine which matches user orders is fully custom made. We also maintain exchange’s hot and cold storage wallets which require high security standards.

Custom Software Dev for Custom Intelligence Platform
"Blank was willing to take on anything. The communication was very easy and friendly."
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m the VP of engineering at Databook, a SaaS company located in California. We offer a custom intelligence platform that provides insights for enterprise sales organizations.
What challenge were you trying to address with Blank?
As a small company, we needed the support of either having more engineers in-house or contracting someone external. We had to be very careful with customer data because many of our contracts were with big enterprise companies. These companies asked us not to have contractors working on the backend or have access to the data. That was why we decided to have an in-house team working on the backend and brought in an external company to take care of the frontend, where they didn’t need access to the customer data.
Our web application was based on AngularJS version 1.6. It was an old version, and it had a lot of vulnerabilities. The version wasn’t maintained by the community anymore, so we needed to migrate it into React.
What was the scope of their involvement?
We brought Blank in to take care of the project. They started moving features one by one into the new React app. We had to keep those two apps customer-facing and make it seamless for them while we were moving everything from one to the other.
Blank was reimplementing, improving, and adding new features to the new web app. We only engaged with them for the custom software development because we’d already given them the UI/UX design.
What is the team composition?
We worked with Blank’s CEO and with two full-time engineers.
How did you come to work with Blank?
One of our engineers recommended Blank to us because of the quality of their code. This person had worked with them in the past.
How much have you invested with them?
We invested $90,000.
What is the status of this engagement?
The project lasted from September 2020–March 2021.
What evidence can you share that demonstrates the impact of the engagement?
Our main metric was the performance of the web app. There wasn’t a quantitative metric because we were only migrating the existing functionality to a new framework that offered the same. It was completed successfully without any detriment.
The second metric we measured was the visual impact on the ease of use. We had the same functionality but with a different design. It was very acceptable to the internal team and customers.
How did Blank perform from a project management standpoint?
The project management was great, and the communication was constant. I was in contact with Blank’s CEO through Zoom on a weekly basis to supervise the project and discuss specifics. In addition, we brought Blank into the 15-minute daily standups with our internal team.
We also had one of our engineers be the point of contact with them to review the code and help their team out.
What did you find most impressive about them?
Blank was willing to take on anything. The communication was very easy and friendly.
Are there any areas they could improve?
One thing Blank could improve is to have a bigger overlap between their teams. Having a project manager on their side to take care of everything from the beginning would have been good because of the time difference we had. We gave that feedback, and Blank fixed it right away. They performed amazingly.
Any advice for potential customers?
Do a similar setup as we did and have daily quick catch-ups. It really helps to get quick feedback on how things are going. Let Blank do the work.
