Assume, based on comparables, that they sold a 20% equity stake in their company in return for this investment.
Then Polarsteps did this deal at an estimated €3.0 million / 20% = €15 million post-money valuation.
Post-money valuation = investment / equity stake sold
Pre-money valuation = post-money valuation – investment
Do you have a different estimate for the stake that Polarsteps sold?
Then leave a comment about what you think it is, and why!
