Invest

Back SkyDrive whether or not it has agreed: your intention joins the pool on SkyDrive, passed to the Fundraising Desk of its country once it reaches critical mass. Backing on Uback (pronounced “you back”) means declaring an Interest (free) or an Intention (coming soon). Backing does not mean that this company is raising funds or that a shareholder is selling shares, and it is not a commitment to invest. Any deal, through a funding round or a sale by an existing shareholder, is handled by a partner desk: the Fundraising Desk of the country for a round, the Secondary Sales Desk assigned to the company for a sale.

Pool on SkyDriveBelow threshold

BackersBelow threshold

Paid intention · valid for life · movable until you sign with a partner desk. If the company does not follow up, Uback invites its Backers to move their intentions to a competitor or a similar company. Investing in non-listed companies carries a risk of losing all the capital invested.
