Question
As an example, the startup can offer:
1) 5% equity ownership.
2) Discount in the next round.
What could be some other examples?
The responsibility of the advisor is to help raise $100k.
Answer
The answer provided here that suggests an advisor should earn a fee and a "percentage pie" is simply ludicrous. But it's also unrealistic to expect an advisor to be responsible for raising angel money. While 3rd party fundraisers and financial advisors do appear in some transactions at much later-stage companies, it would not be a good sign for an advisor to be actually fundraising at the Angel stage.
The advisor can (and should be able to) make introductions but an introduction is just the beginning. An angel is making the decision based on their interaction with the founder.
Happy to talk through more details in a call.
