As someone who started a Saas in a niche market that had a long standing leader I&#x27;d say this:<p>Ask yourself not whether there is a leader in the market, but whether that industry is in flux and whether the buyers in the industry are apt to seek and adopt something new.<p>If you don&#x27;t get the sense that things are fluid in your target market, then I&#x27;d recommend staying away. In some markets people just don&#x27;t like change.<p>IMO it&#x27;s not about whether there is a leader, or whether it&#x27;s an untapped market, it&#x27;s all about how the market reacts to new things.<p>Look for reactions to other products in the same market on social media. Was there excitement? apathy? Why? Consider this a preview of the kind of reactions you&#x27;re going to get. If you don&#x27;t like it stay away.
