Propstack – your real estate CRM that thinks ahead. On the go, too. A real estate agent’s day doesn’t wait. Neither do you. With Propstack, your real estate CRM is always with you—where decisions are made: at the owner’s property, during a viewing, and between appointments. Get important work done faster in the moment instead of putting it off until later. Your personal cockpit shows you what matters today at a glance: key deals, upcoming appointments, and open tasks. Start your day focused and be ready for every next step. Create properties quickly, capture relevant information on site, and update it without detours. Propstack connects properties, contacts, and deals so you don’t have to search for or enter the same information twice. Publish properties directly to marketing portals and keep every detail up to date. Communication is faster, too: open an email, link the contact and property, choose the right template—and the property brochure and attachments are added automatically. Delegate tasks directly to your team. Save time and order floor area calculations directly in the app. We’ll notify you as soon as the documents are ready. With the AI features of Propstack AI, you can dictate property details, analyse photos, capture a property on video, or scan documents such as energy performance certificates—instead of typing everything out manually. Propstack extracts suitable images and recognises relevant property data from speech, video, and documents. Relevant fields are pre-filled for you. You review every result before it is saved to your CRM—quickly, transparently, and always under your control. With Proppi, your day picks up speed.
