This is beautiful and navigable. Well done. A few product suggestions:

* Accounting is really important; Meetings less so. Think about your main headers. * Make it clearer what the order is you're listing the apps: alphabetical, by rating, newest, etc. and let users toggle between them * Have curated lists of apps for various startups and small businesses: freelancers, web apps, consulting firms, bakeries, dentists, etc. * Have "you might also like" or "consider these" apps on any particular app's page
