🎯 Is my idea actually solving a real problem? Most founders build what they want, not what the market needs. Customer discovery is the single most important skill at this stage — and the most skipped. 🤝 Do I need a co-founder, and how do I find one? Solo founders struggle with fundraising and bandwidth. Finding the right co-founder — with complementary skills and aligned values — is critical before building anything. 📊 How big is the market, and should I even bother? Investors and co-founders will ask about TAM/SAM/SOM. More importantly, a large enough market separates a lifestyle business from a venture-backable startup.What idea stage founders struggle with the most

How many customer interviews do I need before I start building?There is no perfect number, but 15–20 interviews with your target customer segment is a strong starting point. The signal you are looking for is pattern repetition — when you stop hearing new problems and start hearing the same pain points described the same way, you have enough to move forward. Never fewer than 10.
Do I need a co-founder, or can I solo-found a startup in India?You can absolutely solo-found. Many successful Indian startups began as solo ventures. However, most institutional investors in India — particularly at the pre-seed and seed stage — strongly prefer teams of 2–3 founders. The workload of building, selling, and fundraising simultaneously is also significantly more manageable with a co-founder.
What is a smoke test and how do I run one for my startup idea?A smoke test is a low-cost experiment to measure real demand before you build anything. The simplest version: build a landing page describing your product and its pricing, drive a small amount of traffic to it, and measure sign-ups or “Buy Now” clicks. If people are willing to commit their email or even payment details before the product exists, that is strong validation. Tools like Carrd, Webflow, or even a WhatsApp form work perfectly for this.
