I'm trying to figure out the value of my company for our seed round. I'm currently building the product with a very large company that wants to be a customer and probable investor.
We are a SasS company in the senior care market sector. There are two similar companies which had seed rounds in the past year, Filament Labs and Medocity.
From my experience I would not advise you to go with Venture Capital when you're a start-up as in the end they will most likely end up screwing you. A much better source for funding would be angel investors or friends/family.
The question of how much equity should I give away differs for every start-up. I remember with my first company I gave away 30% because I wanted to get it off the ground. This was the best decision I ever made. Don't over valuate your company as having 70% of something is big is a whole lot better than having 100% of something small. You have to decide your companies value based on Assets/I.P(Intellectual Property)/Projections.
I assume you have some follow up questions and I would love to help you so if you need any help feel free to call me.
If you get into techstars they take 7-10% for $118k which is about a ~$1M valuation. If you're pre money, Seed investors usually cap their valuation at $4-6M, so depending on how much you need is how much they are going to get. That said VC's tend to have a much better run rate then angels. They tend to help you more with further rounds. Really good incubators (only a handful of them exist) can also help further your secondary raises, startups tend to raise on average $2m after graduating.
But the real question is why do you need funding? Are you ready for funding? What is the use of funds directed into?
Very tactically, at the early stage valuations are mostly arbitrary.
Typically it goes by the market rate, geography, relative strengths of the investors vs founders, growth rates, ARR, etc.
For a $1M seed round (similar to filament):
A VC firm will look to get 10%-20%
A group of angels/seed will look to get 15-25%.
This is assuming you have some traction with good growth.
Your negotiating position and skill will determine which end of the scale it will be. The funding scene is also quite variable based on who you are, and hence YMMV.
