What does the company do well? We always try to convince people to use WP Engine. There's no hosting service provider that even comes close.
Support is incredible, services are fantastic and performance just as good.
What does the company not do well? Domains and email.
If WP Engine did domains and email... Wow they would absolutely take all my money.No scaling price option (ie: a pay as you go for what you need). Installs sold in packages.
What about the company do you wish you had known before purchasing? That I had known about them sooner. They've really helped my company scale as a web design studio.
