Invest in appointment booking, together

Uback aggregates investment intentions from business angels, family offices, corporates and sector specialists worldwide. Every ranked company already has professional investors on its cap table, who have negotiated a shareholders’ agreement: you don’t start from a blank page.

Strength in numbers

Alone, a small ticket opens no doors. Together, Backers carry weight.

Declare an intention

On a company or a sector, with a ticket range. Paid, to show you are serious; transferable as long as it has not been converted.

Critical mass is reached

When the number of Backers and the total of their intentions cross a threshold, the licensed partner contacts the company and presents this demand.

The licensed partner structures

If the company’s expectations and the Backers’ converge, the partner builds a transaction and presents it directly to the Backers concerned.

Closing

Capital raise or sale of existing shares: small tickets are pooled in a common vehicle set up by the licensed partner. Each Backer decides whether to take part.

Uback does not advise, does not negotiate, collects nothing. Each transaction is run by the licensed partner of the company’s country, under the law that governs its shares.
