Open is a video calling and messaging platform. What makes Open unique is how you share your subjects of expertise. Rather than writing a biography or list of your skills, your experience discussing subjects with other users is what builds your reputation. Users on a call must agree to discuss a particular subject. Once each user agrees, a timer starts and the amount of time spent discussing that subject is added to each person's profile and the public "subjects" page. This ultimately results in the ability for users to go to the subjects page, search for a subject, and find the most experienced person in that subject. Since we all have limited time and time is very valuable, Open allows users the ability to pay users for their time to discuss subjects. The amount of money you've received to discuss a subject also adds to your credibility. For example, I would be happy to pay Tom Hanks $100 per hour to discuss "How to become an actor." Realistically, I will probably end up paying Joe Schmo $30 per hour to discuss "Best online acting courses." These simple features enable users to build a robust network of knowledgeable contacts and enables more efficient learning.

With over 30 years of combined experience in the hospitality and technology sectors, we have developed the first and only solution that allows customers to access and book hotel meeting rooms online through a seamless and intuitive hotel sales and catering system called greatEvent. Hours and days of event planning and booking can now be reduced to minutes for your hotelier staff. Your staff will no longer need to spend significant time on the phone with customers, working out the details of an event because now the customer can complete the whole booking online, either by website or app. Unlike all other lead generation platforms, greatEvent gives customers real-time visibility into meeting space inventory in member hotels and venue locations. This same inventory access solution has been a dynamic success in airline, hotel room, and car rental booking for years, and we have now brought this same solution to the event booking industry. How it works for the consumer: The customer uses the greatEvent website or app to search for all available meeting spaces (inventory) at hotels and venues within a desired location and timeframe. When the customer is ready to proceed with booking, the customer can register by providing essential contact information and begin the booking process. Once the customer books the inventory, the customer will seamlessly move to the event planning process. The customer can then make every possible decision for the event based on all options available by the hotel or venue (i.e. catering, seating, entertainment, etc.). All billing and processing are handled online, and a confirmation email is sent upon completion. The customer also has the option to finalize all details by phone if necessary. How it works for the hotelier : The hotelier has its own sales and catering platform that mirrors the customer platform but also allows for complete customization related to all details of room booking, sales, catering, and entertainment. Through the platform, the hotelier is also provided with an intuitive dashboard that displays all customer leads with the ability to assign these leads to staff. The dashboard is easy to use and requires minimal training, allowing other staff to operate when a salesperson is unavailable. The hotelier has the capability to review, edit, approve and close any venue booking transactions. Overall, greatEvent is designed to help you increase revenue through low-cost lead generation, while at the same time reducing your overall cost of sales. Most importantly, sales teams will now have more time to spend on sales calls, building relationships, and capturing business!
