Louisville desk

Office photo: pending a real photo

We will publish one current photo of the Louisville desk when the founder approves it. We do not use stock photography as if it were our office.

Address: 815 W Market St Ste 303, Louisville, KY 40202 · visits by appointment.

What we do not publish yet

Founder headshots (current, approved) — photos are marked available on request until then.
One real office/desk photo for the facility slot — no stock image is used as our office.
LinkedIn profile URLs for the founders — not published until each URL is confirmed.
Customer or partner references/photos with written permission — none are shown.
A real scheduling URL for book-a-call — the link opens the desk email with a two-times template until one exists.

Ask the desk if you need any of these for a procurement file. We confirm what exists in writing rather than publishing a placeholder as fact.
