Invest

Back AssemblyAI whether or not it has agreed: your intention joins the pool on AssemblyAI, 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.
