Many websites feature a photo of the owner or directors of the company, but a photo can only do so much. Having a short film of you can really bring your passion to the website visitor. Through this they can see what you went through to start your business, or what drives you.
The reason that your customers come to your door and buy from you, (even if its online) is because they share your passion. If you run a vegan restaurant then they will want to eat your food and be looked after by fellow vegans. If you run a vegan company then you can assure them that you only supply them with animal friendly products. Imagine your business captured in a short film that really brings your customers inside your business.
Nothing speaks better about your business than your customers and if they are filmed making their comments it makes others really believe and live your story.
