In some startups person like you could be a CTO but that depends on a company. I think you should push for a promotion after 3 years. If after 5 years you will still be a Sr developer and people will be hired over you then that will not be a good sign for your next employer (and you will need one as a current one would seem not to value you that much). I would push this hard or would leave. For equity it depends what is your salary and what is your market salary, but yeah usually people in your position get some equity. But if they pay you well equity is not that important as it's rarely have much value for employees.

Thanks. Makes lot of sense. Also thinking if there is any other good title between CTO (which I feel is somewhat vague and might take my peace away) and Sr Dev.
