Who is Moss and how do I know they are reliable?

Moss has gone through the most rigorous due diligence processes one can imagine: we have as clients NYSE listed Gol and B3 (Brazilian exchange) listed Hering, Arezzo, Bionexo, Prosus's Ifood (largest food delivery company in Latam).
We have as investors GP Investments (via its VC fund the Craftory) and its chairman Fersen Lambranho, B3 listed and the oldest and one of most reputable private equity firms in Brazil (http://www.gp-investments.com/ created by the ABI / Heinz shareholders). Other investors include many C-level or board level Brazilians, such as Nizan Guanaes, Fabio Barbosa (on Itau, largest Brazilian bank, board), Fabio Alperowitch.
In the US, we count with Celo as a shareholder, the MCO2 is on the Celo reserve (the only carbon credit that is part of a stable coin reserve globally = https://celoreserve.org/ , and the NYSE listing of One River BTC ETF has gone through SEC due dilligence and investigation. As one can imagine, listing at Gemini and Coinbase and Mercado Bitcoin (Latam's largest exchange) also requires extreme due diligence.
Furthermore, we have hired Perkins Coie to emit a legal opinion on our tokens, we have gone through audits by CertiK for the security of the code, Armanino for our ledger and double spending risk, EY for company flows and governance and our carbon calculator, and Deloitte for global taxation issues. Oh, and we are finishing audited financials. We have also just finished a Series A round with Acre.vc, Jive (a large Brazilian multibillion dollar special sit fund), and Latam's reputable agtech VC fund SP ventures.
