[I work for 1Password]
1Password is not competing with Vault. In fact we have very good relationships and mutual respect with HashiCorp on many levels.
Also Secret automation integrates (acts as a provider) with HC Vault[1]

They're not competing with Vault,they see this as an alternative for simpler use cases where Vault is overkill, or a complimentary product otherwise.
It's good to have independent competition in this space.
