From their official website:

Who are the investors?
To support Orchid Labs and its mission, the company has raised $4.7M seed SAFT (Simple Agreement for Future Tokens) from investors including Sequoia, Andreessen Horowitz, DFJ, PolyChain Capital, Metastable, Blockchain Capital, Crunchfund, Struck Capital, Compound VC, and several other funds and angel investors.

Seems this project raised enough and has not any intention to do public sale.
