Spot 9 is a Berlin based start up company with a vision to create a new experience in the Banking/Crypto sector for its customers. They are striving to create a Mobile Application which will bring together all of a customer’s bank accounts as well as their Crypto Currency holdings in one system, and allow them to effortlessly undertake all standard banking transactions, as well as trade in their desired Crypto Currencies in one place.



The client needed to create a Mobile Application that it could show to its investors, that would allow customers to Register within the system, conduct “Know Your Customer” (KYC), allow them to add other Bank Accounts, as well as see their Crypto Currencies.

In addition, management needed to understand the forecast cost of delivering the main mobile application, as well as having a MS Project Plan, list of deliverables, Project Management Plan and detailed Risk, Issues, Constraints to agree with its Investors to move forward with the Delivery Phase.


The client already had done a detailed UI Design Phase and had a clickable prototype in InVision, however, the solution needed to be enhanced based on additional stakeholder input, and was progressed into Figma, where we also created Zeplin Templates to be used by the iOS Front End.

The Front End was built using iOS Native, and key features for the client, including Registration, Login, Reset Password, Home Page (Retail Banking), Add Bank Account, Home Page (Crypto Currency), Crypto Portfolio and Crypto Market data were all built and integrated with the back end Micro Services “End Points” for Integrations and Database.

The Back End was built using a mixture of Go Lang and Java based on the individual needs of the Micro Service Integrations with the third-party Service Providers (see the full presentation).


The PoC Mobile Application allows the client and its investors to visually see a subset of the end product, so it could help them understand how it would look and feel for their customers.

The Project Management documentation provided all the detailed information for the client, to understand, cost, effort, resource needs, timeline as well as risks, to make an educated decision on whether it is right for their business to proceed into the Delivery Phase of the product.

This enabled the client and its respective investors to have all the information they needed to decide to proceed with the delivery of the project, using Knubisoft as a key Software Delivery Partner.
