For A new D2C brand to begin today and grow, is it possible to grow organically without any marketing budgets. If so, how??

Tricky to the core. But a one word answer to it is creativity.

You or someone on your founding team needs to breed ideas and execute them fearlessly. Be on the right platforms, figure out the persona, send free emails, crack channel partnerships, test messaging…

You will soon have cracked one or two solid ideas that you wont mind scaling because you got only so much time.

Happy to chat further over DM :)
