Every investment decision must be based on an examination of an exhaustive set of information provided by the entrepreneur on his online profile. Spreds only proceeds to a limited verification of this information and does not control the investment opportunity within this company. Spreds did not verify the extent to which the business plan is deemed realistic and does not intervene in determining the final terms of the investment, including the retained maximum valuation. Spreds will align itself with the financial terms negotiated with the co-investor(s).


TwinnTax is an app that fills and optimizes Tax Returns. It asks only simple questions, gives advices to reduce taxes from one year to another and helps its clients to take better decisions. TwinnTax's vision is to become the tax assistant for European citizens.


Many people think that tax returns are difficult and stressful to fill in.

As a result, people have 2 bad options :
- they choose to fill it in themselves and search for help on random websites. For complicated situations, it takes up to 20 hours, they can still make mistakes or miss possible deductions.
- they pay an accountant €50 to €200. They make an appointment, they gather their papers, go there by car, and use old technology.

EUROPEAN CITIZENS BELIEVE TAXES ARE TOO HIGH, SO they are usually very keen on receiving tips to lower taxes. Many workers would rather buy deductible goods they do not need, instead of collecting cash after being taxed.

The next few months :

The next TwinnTax objective is to start paying customers in October 2019, for Belgium. The application will then cover more than 95% of the actual possible cases. TwinnTax targets 200 declarations.
This service allows late arrivals to submit their declaration via a proxy and thus avoid paying a fine (from 50 to 1250€). The asking price will be 29,99€.
The second objective is to boost the diagnostic function of previous declarations. The advertising campaign will take place in mid-November so that users can still subscribe to deductible products.
The third objective is to complete and optimize 20,000 IPP returns by June/October 2020.
The fourth objective is to launch the French application in February 2020.
