Seoable for Flex
If you are part of Flex (or you are a YC founder who looks at Flex and thinks that is the kind of business I run), you probably do not have time for a six-month SEO agency contract. Seoable was built for that. Audit your site, queue 100 ready-to-publish posts, and run it all from your AI assistant.
About Flex
Flex is a payment platform for businesses to accept HSA/FSA, unlocking the $150B per year sitting in HSA/FSA accounts.
