I'll support the contrary viewpoint that you should limit your audience.

You can't have a new product targeting both professionals and consumers. These are very widely different markets, that buy differently, that you'll reach differently, for which you need different messaging, features etc.

For a new product, the more targeted and focused your audience, the better.

"for professionals" for example is far from targeted enough.

"for growing startups" is a more focused audience: they tend to hang out at the same place (online on forums or offline in conferences for example) they exhibit some of the same buying behaviors, they have similar needs, etc.

Not saying "growing startups" is a good target for OP's product but just using it as an illustration.
