What white label means here, exactly
We are your supplier, not your competitor. Your client stays your client: we don't contact them, don't appear in their inbox, and don't pitch them anything. If you'd rather we join a call, we'll join as part of your team and follow your lead on how we're introduced.
We'll put that in writing, including a non-solicitation clause, so it isn't a matter of trust in a first meeting. The work is yours to present as yours.
