Open to the offer

Open to the offer, branded OTTO, operates a web platform for buying and selling residential property online. Homeowners can register a property in a few minutes and be listed as "open to the offer" without committing to a sale, then collect offers from qualified buyers. Buyers search an inventory that combines these owner-registered homes with listings aggregated from elsewhere on the web, and can submit offers directly through the platform rather than through paperwork-heavy negotiation.

The platform is designed to work with or without a real estate agent, and includes collaboration features: users can invite partners, family, or friends to save, rate, and comment on homes, and can share a board of saved homes publicly. Sellers control privacy and process settings, including whether the property address is shown, whether buyers may message them before making an offer, and whether in-person showings, virtual-only showings, or no showings are permitted; inspections remain mandatory. Listing contact information is kept private. The company also markets to realtors and lenders as a channel for their businesses.
