Need benchmark for a business valuation of start-up company in ed-tech.

I need benchmark from investments in different early stage (seed stage) start-ups. Criteria: 1. The investment should have been in an ed-tech company (focusing on corporate education/learning, not for public education) or in a data-analytics company. Both types of companies should offer SaaS. 2. The investment must have taken place after after 2010. 3. It should be an early investment in the company (seed stage), preferably the first public investment. The information you should include in your presentation: - Name of the company - Description of the service - Time of the investment - What sequence of investment (i.e. is it the first, second, or a later one) - Age of the company at the time of the investment - Revenue at the time of the investment - How much was paid and for how much of ownership of the company. - Weblink for more information online (e.g. press release or other)
