Success comes for a reason and rarely out of nowhere. You may be congratulated for it but then also asked the question "what will you do next?"
Don't think you can tell investors that you believe it's the best way... You'll need a real justification.
What was done to achieve success? How was it done? Measure everything that happened and base your actions on real facts.
With a good rationale, you'll be able to convince people and bring forward the next success.
