How do you validate your SaaS idea before writing a single line of code ?

Validate your idea by talking to potential customers in your target market! Set up interviews or surveys to get real feedback on what problems they face that your SaaS could solve. Don't just rely on your own assumptions. And see if you can get a few people to commit to pre-paying or signing up for a beta before you start coding. Getting that early validation and buy-in is key.

Talk to people, definitely. Build a landing page describing your idea and start collecting emails to gauge interest. Maybe even offer a presale or beta access! The presale doesn't have to be the final product, just something to validate demand before you invest too much time building. Also consider looking for communities online related to your target audience and posting there to get feedback on the idea. The key is validating the problem and demand before getting too deep into a solution!

Totally, validating the idea is crucial before diving into the code. Talk to potential customers, do surveys, get feedback on a landing page, etc. There are also tools like Product-Market Fit Scorecard, ProductValidate.com, or even using AI like ChatGPT to mimic customer conversations that can help validate demand and product-market fit before investing a ton of time building. The key is getting real data and insights from your target market to ensure you're solving a real pain point they'll pay for.
