My current work profile as a business development and account manager. My role majorly constitutes acquisition of new B2B clients. My role also involves working closely with the Sales Director to create required product catalogue, new marketing strategies, and product value propositions.
The starting point is creating a MVP. You also need to check on your tech know how and capabilities inhouse beforehand else you might end up burning too much capital on creating the prototype itself. I would suggest go for open source development stack to stay within the budget.
