Frequently asked questions (FAQ)

Frequently asked questions (FAQ)

The Foundation for Market Information Research (SOMI) is a non-profit organization set up to identify and influence issues of social importance. Among other things, SOMI is committed to protecting the fundamental rights of consumers and minors who use online services. SOMI investigates abuses, informs the public, and helps disadvantaged people. SOMI does this, among other things, by conducting collective proceedings and claiming compensation.

The full statutory purpose of SOMI is included in our statutes. You can find it here.
SOMI is a non-profit foundation. We have an independent board of three members. The members are listed above. The board is responsible for the day-to-day running of the foundation. SOMI also has an independent supervisory board. The members of the Supervisory Board are also listed above. The supervisory board supervises and controls the board.

SOMI aims to be financed as much as possible with contributions from the participants in our campaigns and activities. We then do not have to pay large amounts to external financiers but can pass on such benefits directly to the people we represent. SOMI meanwhile has sufficient equity to carry out its activities, including the case against TikTok. Most of that capital was donated to SOMI by Reunion Ventures B.V. based on an agreement last updated as of December 2022. Reunion donated the money without asking for anything in return, with the aim of bringing about the social changes for which SOMI was founded. In order to be able to immediately absorb external costs for the storage and control of data of an acute large influx of new participants, SOMI has charged an advance payment for services from some point in time, in the form of a general registration fee of € 17.50 for new participants in its activities.

As of February 29th, 2024, SOMI will issue profit rights in legal proceedings to finance legal cases and represent victims throughout Europe. We are the first to do this with our Garantieprocescertificaten and Procescertificaten Serie 2024.

SOMI offers its certificates to consumers and investors interested in financing social causes and collective lawsuits. SOMI wants our society to be the first to benefit from these actions. Therefore, SOMI chooses to remain as independent as possible from commercial motives that could undermine the victims' right to compensation. We prefer to share the results with the participants in our actions. Click here for more information.
The members of the Board of Directors and the Supervisory Board receive an hourly rate of € 75 for their work for the collective actions, such as for TikTok claim.
With the SOMI app, you can instruct us to manage your personal data and to enforce your rights on your behalf against companies and organizations that process your personal data. For example, we can make a request for access on your behalf or request that your personal data be deleted. You can also register for collective procedures of SOMI via the SOMI app.
You can participate in the collective action by completing the online registration form. It is also possible to complete the form for a minor of whom you are the legal representative.
You can withdraw from the collective action free of charge without giving reasons within 14 days after registration by sending an email to welcome@somi.nl. You can then cancel your participation without giving reasons, subject to a notice period of 30 days.
We work on a “no cure, no pay” basis. All (process) costs are therefore initially borne by SOMI itself. This means you run no risk. If the claim is unsuccessful, you will not have to pay anything. If the claim is successful, SOMI will attempt to have its costs reimbursed. We also assume that this will work. If the judge does not grant this, SOMI will withhold 2% of the compensation to be paid to you on the basis of the participant conditions with you to cover (part of) our costs. This is in line with the Claim Code 2019. The final percentage is determined reasonably by the judge and depends on the amount of the (process) costs and the amount of the total compensation.
SOMI does more than just organize collective claims. SOMI considers it useful to involve its participants as much as possible in the decision-making process. For example, during the TikTok claim, SOMI asked its participants to think along with SOMI by completing a questionnaire about the possible next step.
