# Introduction

## Intro

Here at [Thetta.io](https://web.thetta.io) our goal is to protect all parties: our investors, core team, community and clients. We spent many days discussing and analyzing options and we came up with a list of different ICO approaches and models.

**Disclaimer: Please note that the goal of this document is not to provide an orthogonal classification of different ICO options. In fact, certain properties of these approaches can be combined. Accordingly, this document (at least, in its current state) should be considered as an unsorted list of different ICO approaches.**
