Not sure if you&#x27;d consider StatusPage.io as a &quot;clear leader&quot;. They claim to have around 2000 customers ( <a href="http:&#x2F;&#x2F;blog.statuspage.io&#x2F;introducing-private-status-pages" rel="nofollow">http:&#x2F;&#x2F;blog.statuspage.io&#x2F;introducing-private-status-pages</a> ) which I consider a small number of a potential target group. From some other posts, their revenue is around $3M&#x2F;annually.<p>So if this is a $5M potential market, probably there is a clear winner. If this is a $100M potential market, things are just starting.
