Xero has really blown us away. It is really easy to use, even for people who do not have an accounting background. It also integrates with our bank accounts in 3 different countries so it is really useful to track every account with one tool.
At the rhythm that we are growing now, we will have to move back to Salesforce, unfortunately. I am not looking forward to it because I hate the UI, but it scales better for bigger companies.
Marketo behavioral scoring is really good. We want our salespeople to be able to effectively track their leads, and Marketo is really effective in this sense.
We like HubSpot because it is lighter weight and way easier to use. At the rhythm we are growing now, we will have to unfortunately move back to Salesforce. I am not looking forward to it because I hate the UI, but it scales better for bigger companies.
We built our own subscription service using a combination of Stripe and the open source software Kilbill.io because all the tools that we explored were too expensive to get the flexibility that we wanted. The admin interface is not really pretty but it does the job.
Google Drive is used by everyone in the company.
For product design, two of us are on Dropbox: myself and another colleague. I signed up really early to Dropbox so I have 100GB available. I am getting to the point that when I sync my Dropbox, it slows everyone’s connection. We do not have this problem with Google Drive.
We use CakeHR for everything: calendar, benefit plans, vacations, employees personal information. We are moving off of CakeHR because the functionality is limited and has not grown as fast as we wanted, but overall, we recommend CakeHR for startups in their initial phase as it is cost effective and does everything we need.
We are collaborating with the Slack team to improve the functionality of Slack, but at this point for communication Slack is still not nearly as good as Skype.
We also use GoToMeeting; it is not the best tool and we are looking to move on to something else, such as join.me.
We use Assembla for deployment and planning our product roadmap. They do not have a mobile app but their browser application is awesome. We love them - Assembla is the one tool that we could not do without. Our company could not function without it.
