Changing a name is certainly a tricky topic. There is no right or wrong answer.
The brand has to resonate for you, and for your vision of the business. Like Debra said, it can be very expensive and can also negatively impact your business. There have been some spectacular failures on rebrands but also some amazing changes too.
Depends on how much money you have, how much brand recognition you have, the trade off of how many customers you may lose in the change vs how many you may gain.
From personal experience, I had a company where we thought of changing the name. We decided not too as it already had a lot of brand equity, but the topic kept coming up for years and it always got harder and harder to change as brand equity built and the costs to change grew. Part of me wishes we jumped off the cliff in the early days and did the re-brand back when the company was small.
Sometimes, the emotion of how you feel about your brand for your company also needs to be taken in to account along with the rational and economic reasons!
Food for thought, best wishes on quite a tough decision and inflection point. Happy to chat further.
