I really appreciate these suggestions. We're a fully bootstrapped ~20 person, $5M+ ARR company in the DevOps space. We're growing quickly and often wonder what an extra $1.5 - $3M could mean for us, but don't want the overhead associated with a traditional investor, nor to invest the time in raising. We get emails from 3 - 4 VCs per week, but never any alternative funding options like the ones you listed. CalmFund in particular could be worth exploring. I wish this space ("Tech Mittelstands"?) were better established.
