In some ways, Google Analytics is pretty robust--it's like Photoshop. There's a lot there and I think it's just about figuring out how to customize it. What it comes down to is that it's powerful, free and easily configurable. Google Analytics might not be quite as user-friendly as some other services--it takes some time to get working--but it's well worth it.
We love that Streak is so lightweight and lives inside of your existing inbox. The features are actually really good. We’re email power users, so it suits us. At this point, it's just premature for us to have a full-blown CRM.
I've used MailChimp for my family's small business before this, so I already knew it. MailChimp’s free account is great, though I think I was actually grandfathered in on some of the premium features. I like a lot of their automation capabilities, so I haven’t felt the need to shop around for alternatives.
Xero has been up and down. Initially, I really wasn't into it. I've come around, but I get the sense that an accountant designed the software. You can't ever really void anything, so you can’t just hit CTRL-Z to undo which takes some getting used to. We have it working now in a way that we’re happy with, but it wasn’t as plug-in-play and there were some setup costs the first month or so. I’d also love for Xero to be easier to integrate with the operational side of our business, but that seems to generally require add-ons which are relatively expensive and not necessarily worth it for us at this point So Xero has been good for accounting, but less useful for financial and operational analysis.
Hootsuite is a great solution for scheduling content so you don’t have to think about social media every day.
Sketch is basically design software for UX and UI. It’s an awesome tool. We just used it to revamp our entire website, and it was really helpful for resizing images, doing mockups and more.
I love Asana. It's super flexible, so it's nice for project management, but it's also good as a lightweight database. For us, it functions almost like a CRM for suppliers; I keep track of where they are, important stats on them, etc. It's just crazy flexible, and a nice mix of customizable and intuitive, so we've used it for lots and lots of different things. It also has really great plug-ins; for instance one of their plug-ins can tell us when a new shipment will arrive at our factory.
