Avoid investors. You don't need a huge team. Try to bootstrap everything, preferably on the side (can you reduce your work hours? I reduced my hours by 50%. I never had pressure to make money and developed the project for nearly two years). Spend the time building product. Automate everything else you can. Can you reach users? Otherwise think about a partner that already has an audience. I have spend $0 on anyone besides my partner (my brother, who owns his own company) and a bookkeeper (but most of payments is as simple as it gets - app store / play store. Better pay 15% fee and don't care about VAT, processing, refunds etc (and save the salary for an employee for that). But I spend on managed infrastructure (cloud serversm managed database, S3...) You can go very, very far alone. I'm the solo dev and ceo on a complex project that competes with companies with many more employees. When you start gaining users: ask every single one for feedback, questions and improvements. Build a good FAQ.

We are profitable and growing in an established market with many players.
