Call an early board meeting and aim for disciplinary action against the CTO. Founders don't get kicked out by employees. You also need to establish leadership power within the company as a founder vs being pushed around or treated like a code monkey. Even CEOs can be removed from their high horse should there be collusion here between the CTO and CEO. If you feel this may be the case, seeking some legal advice so you can throw powerful words at those colluding should rattle the bird cake a bit. Just don't bring emotion in. Founders are key to any company. Roles change. Part of a growing company. Founders keep the fire burning. Any smart investor will tell you the same.
