ML-driven mobile app for debt collection
An app that uses machine learning to help companies collect outstanding debt successfully. The mobile app is suitable for both companies and customers.
Instead of cold calling or sending debt collectors, the app sends texts and push notifications. Users with outstanding debts can personalize the time, channel, and payment arrangements that are comfortable for them through the app.

The machine learning algorithm personalizes the collection experience, boosting higher engagement by individually tailoring a unique journey for each consumer. To increase the overall financial performance, the app keeps optimizing every step such as the right type of message, outreach time, and communication cadence.
The crypto wallet to scale your business and make your accountant happy.
The app allows businesses to automate payments, bookkeeping, track wallets, create an approval workflow, save time by eliminating human error, and start scaling the business. The wallet is built on the Gnosis Safe wallet (over $1B of ETH is stored there). It doesn't have any access to your funds, doesn't store your private keys, and requires a predefined number of signatures to confirm transactions.

Platform that automates insurance distribution for enterprises
Our client offers insurance solutions to various other platform operators such as marketplaces and booking websites. We created a web platform that enables our client to automate his omni-channel insurance distribution business by offering its customers a seamless and simple integration into existing web environments. Hereby was important that the insurance solutions can be bought within a maximum of three clicks.
App for getting whatever insurance & whenever you need it
We have built a mobile application that provides customers with the ability to buy insurance coverage whenever they need it and for exactly how long they need it - may that be a day, a week or a year. The mobile-first, user centric application offers a streamlined, automated and AI-enhanced experience which enriches both the user and the staff experience.

Moreover, users can buy a monthly insurance subscription, purchase temporary premium "top ups" (ex.: during the time the car is being driven or the customer is flying the plane and etc.) or additional services at any time. The app has been developed with flexibility in mind regarding future service offerings.
CRM for a digital insurance platform
We have created a unique platform that helps to quickly and easily calculate the estimated cost of an insurance quote.

And it's not just "empty" numbers which ultimately will be drastically altered on the final quote. It does this accurate estimate by using logical computing and input data, as well as numerous correlations and dependencies, to make the quote. Insurance calculation is based on the insured person's information: his home address, date of insurance, insurance period, invested amount, demographical data.
