Consulting business ideas
Advisory services built on demonstrated experience and a defined engagement.
How to choose a starting point
Choose a problem you have solved before and a buyer who pays to avoid it. A fixed-scope audit or roadmap is easier to sell than open hours.
Advice carries responsibility. Stay within your experience and credentials, and avoid legal, tax or medical advice unless licensed.
