Invest

Upstage is not open to Backers. A company opens only when a shareholder plans to sell or the company plans to raise.

Back the market instead: your intention joins a pool, passed to the local partner once it reaches critical mass.

South Korea poolBelow threshold

BackersBelow threshold

Paid intention · valid for life · movable until its pool is passed on. Investing in non-listed companies carries a risk of losing all the capital invested.
