How is the project properly valued?

This is a long time of confusion. Because there is no reference, I do not know how the life code should be valued. Some say, what you sell, what you estimate. Make a financial data according to your expectations. F said, you now have nothing, VC will give you a fair price. I used it when I saw the Jinsha River last year. VC will think I even own value do not know, talk about what? This financing move is too important for us, so it is necessary to make a correct valuation of yourself. The value of life password embodies in two aspects, on the one hand is the technical value, it solves the threat from Trojan to account, enhances the user account security. On the one hand is the value of the business model, mainly the spread of advertising mode, and the user's adhesion is more robust. Because the life password is intended to be controlled by the fingerprint device, this will improve the safety of the first mate, while the fingerprint is limited by the Life password license, however, users in the short term may be limited in terms of multi-purpose, we need to rapidly expand the relevant network applications to meet the needs of users. Today, the way to determine the value of evaluation, another day and the team to discuss. One is the size of the ad. The revenue that may be generated when starting a profit channel in the future. One is the market share of the total size and life password expected. One is the future expansion of the proliferation of services, including fingerprint music, fingerprint booking and other follow-up products brought about by revenue. Life Code cross-station ads without reference, we mainly use the Internet fingerprint verification platform as a Web site landing tools to the Internet site, through the Fingerprint Display dialog box ads, it is necessary and the site layered. Advantages: Compared with the traditional site, the rapid expansion of advertising, the same time on multiple sites to advertise. The total size of the market, currently in the global scope is difficult to find the landing service as a core product to develop the company. And we have the software/Internet fingerprint verification platform as a core product to the site owners in exchange for the value of the user login. How big is the market? Advertising, multiplication services. In fact, through fingerprint technology can expand the proliferation of services, such as the user's fingerprint characteristics and digital music integration, the formation of a specific fingerprint music, and finally the song sold to users. For example, at the moment you need to buy a train ticket to the railway Authority's authorized point of sale, buy a ticket to pay 5 yuan handling fee. The main function of setting up a sales point is that passengers can take the ticket immediately. Fingerprint can help passengers to confirm the purchase of the ticket identity and price control of 2 yuan or so, save the Railway Bureau ticket management costs at the same time to save passengers to buy tickets and fees. The only drawback is that users can not immediately take the ticket, the risk is here. Of course, there are some fingerprint fortune-telling and so on more gossip fingerprint products. In short, all the services that can be done via the Internet, which involve authentication, can be considered, and what we have to do is that those services are most helpful to the user. What are the most important services for users? and the products or services that are preferred or may be purchased by the user. How to correct reasonable valuations?
