Consider what typically exists by month three. A domain, registered somewhere, possibly under a contractor account. Accounts created in whichever name was convenient at the time. A description of the business that has been said aloud twenty times and never written down. Software subscribed to in a rush. Maybe a website, built before there was anything true to say about who it serves. None of that is a mistake in the ordinary sense. Each was a reasonable decision made quickly. But each is cheap to correct now and considerably more expensive after a year of accumulated history pointing at it.
There is a real version of too early, and it is not about time. If you do not yet know what you are selling or who buys it, more digital work will not produce that answer and could make it harder by locking in a description you have not tested. The correct move then is to sell something to somebody and find out. That conversation is still worth having, because the answer might be that you should spend nothing for three months and here is exactly what to do instead.
Which is the point worth separating. Reaching out is not hiring. A first conversation costs nothing and frequently ends with a recommendation that does not involve me, because the honest answer for an early business is often that two free things and a decision would help more than any project. Nobody is going to convert an early stage question into an engagement that should not exist, and if that were the approach, the entire model of working with businesses only in their first year would not survive contact with reality.
The businesses that get the most out of year one are usually the ones that asked questions before they needed answers rather than after something broke. If you are wondering whether it is too early, that is generally a sign you are thinking about the right things at the right time.
