You presumably derive your income from your start-up. You need to present statements for both your start-up and your personal bank accounts. Ideally IMHO you should also show your most recent tax return, and your businessβ financial accounts that demonstrate profitability sufficient to support your personal drawings, not just turnover.
This Should I submit bank statements when applying for a UK Visa? What do they say about me? relates to a UK visitor visa but is applicable in general when applying elsewhere
