Request an Introduction

Claim a Directory Listing

claim-listing

Record a firm's intent to claim its directory listing in any TESSA-operated registry. Pre-OAuth this is a stub: TESSA logs the claim and a representative reaches out to the supplied email within one business day to verify the claimant. Self-service OAuth-2.1 claim flow lands in a follow-up plan.

Request a Quote from a Directory Firm

request-quote

Request a quote from any firm in a TESSA-operated registry. Lighter-weight than request-introduction — explicitly framed as a budget + scope inquiry. Records the request to directory_leads and forwards a structured email to the firm with the prospect's reply-to address.
