The first place to start is with yourself. Ask yourself and reflect on these questions:
- Why do you want to start this company?
- Is there anyone specifically you think would most benefit from having this product over what they have now?
- What is it specifically that led you to want the product to be 'health and environmentally conscious'?
- What do you want to bring to the market that you haven't found available before?
- Why would anyone care to buy this product over what's easily available online or on store shelves?
Having a clear answer to these questions and the reflection and discipline it takes to answer them are the foundation of branding. It is very common to make founding vision/desire a pillar of new brands. Secondly it starts to get you to think about the consumer need state and specifically the "Jobs to be done" framework (look it up).
Another thing I will say about branding is you will find quickly that if you just want to find a name and look and feel, most names are taken. And you need legal help to do a copyright audit of names and territories. You want to submit your top 2-3 names for review (as it costs money per review). But you want to brainstorm hundreds of names.
Though it is important for names to be unique or be obvious what the product is / does, just know that once you land on a name you still have to invest in building equity in the name through sales, good customer experience, word of mouth and later brand and product exposure. So don't fret too much about the name but rather have it come as the result of the work of getting focused on what the brand should be, in consumers eyes -- starting with the questions above.
Also design student friends can help you put together the branding package once you have a sense of what the brand is.
