Our verdict
Companisto concentrates entirely on startup and growth company equity, so choice stays narrow next to wider brokers. It is a German digital business angel network active since 2012 that lets you hold shares online and join investor events for people who want early stage exposure.

How participation contracts work
The company operates its online platform and sets the framework for every relationship with members. When a member buys a stake, the contract is usually concluded with the young business itself, with another member or with an affiliated investment vehicle, rather than with the operator. Participation can take the form of equity, mezzanine capital or borrowed capital, depending on the project. Members can keep the terms for later reference, which helps them understand exactly what they have agreed to before any money moves.
Who can join
Membership is limited to people with full legal capacity to enter contracts, so minors cannot register. Anyone signing up must provide complete and accurate details, since the information supplied forms the basis of the relationship. Registration creates a personal membership profile that is tied to the terms, and buying a stake can open that profile at the same time. Because the network is built around private investors, the process is designed for adults who are comfortable managing their holdings online.
Understanding startup risk
Early stage and growth company equity is illiquid, meaning a stake cannot always be sold when a member wants, or at a value they expect. Many young firms do not reach the stage where investors see returns, and some lose their entire value. Progress depends on factors such as product development, funding rounds and market demand, all of which can change. A secondary market can offer a way to sell existing holdings, but there is no assurance that a willing purchaser will be ready when a member wants to exit.
