The contact page renders four tabs that are invisible to a plain fetcher, so it was opened in a browser. The Submit a Pitch tab states they lead with 500K to 15M investments in Seed, Series A and Series B for Business Software or Healthcare Technology, and links to a live Typeform. The form was verified open and asks for company name, website, location, sector, capital being raised, annualised revenue run rate and a pitch deck link. A separate tab holds a general enquiry form and a marketing address for press only.

marketing619752.typeform.com/to/fUMfKjSector gated. The form's own options are Business Technology, Digital Experience and Healthcare Technology. Stated check is 500K to 15M leading Seed, Series A or Series B.

Worth knowing. The Texas branding and the revenue question are both softer gates than they look. The location list explicitly includes USA outside Texas, Canada, Mexico, International and Remote, and the revenue question offers pre-product and pre-revenue as valid answers. One hard constraint: the form asks for a deck as a link and says no attachments, so host the deck before you start.
