Ever since the DUAL_EC_DBRG backdoor[1], trust in cryptographic algorithms set by NIST has been reduced.
In the case of ECC curves, the NIST curves rely on a number of highly specific but unexplained constants. More info about the safety and security of curves can be found at https://safecurves.cr.yp.to/

When that becomes the case, starting your own company offers much more freedom.
