Is 400k valuation to much for my startup? I will not promote

I’ve recently started my second start-up. After failing to successfully pivot the first one. It’s going a lot smoother and I improved by changing my approach. Instead of 1 year building an MVP. I did it in 1 month etc. Now I have some good early traction and it’s time to build the full product. But I need funding for that. I’m having trouble with the value of the company. Concept in short: It’s a health-game. Where you can compete against friends using your health stats. Here is what I have: MVP: 1400 users testers sign-ups (users aren’t our revenue model) 45% of testers log-in daily. Without notifications. In the feedback forms, users give the app a 4.2/5 We already have 4 payed advertising clients who committed 2000€, 500€ each with a 80% launching customer discount. Including 3 of the biggest Zoo’s in my country. And a massive charity. I also have a content creator who is ambassador for the company with 1 mil followers. And two other 1 mil+ creators lined up. I have a development team on standby who I have experience with building these apps. And now I need 150k for development and the go-to-market campaign. But how much equity do I give away at this early stage. The company is only 2 months old. Is 400k valuation realistic? Do I ask more? Or less?
