"Run your small business as if it was a large business", or, "Start as you mean to go on".
There is a great deal of bullshit in the tech industry; that chaos is somehow normal and that planning and the principles of good management can wait "till we're big". It should be painfully obvious that once chaos has set in, then that is the business environment and it cannot change.
If that environment includes hiring in panic and treating people badly, and the organisation survives anyway, then that organisation becomes one in which toxic relationships are rewarded indefinitely. It will be unsurprising that people like the OP will find it horrifying and be forced out.
