I run a small executive search company and was looking for a system that not only would work like an ATS but could also act like a CRM. I like to batch communicate with my candidates just as much as my customers. Jobadder does this. In fact, working within JobAdder is smooth and powerful. Posting positions is easy, replying to candidates is easy, building templates, etc.. it's all really simple and effective. After reviewing several ATS systems, I felt that it was the most intuitive and easy to use system for my needs at an attractive price point. Plus the customer support is nothing like I've experienced before from a software company. They're very attentive, polite, and solve all my problems with ease. I promise I'm not paid to say that, they're really that good.
There's a few of things that I wish could be improved. 1) You can't import all of your LinkedIn or other database (.csv files) records to JobAdder for free. They will do it but, they will charge you. Seems a bit petty. 2) I wish it was a little more similar to Workable where you would import a candidate and it would automatically scrape the web for additional contact information (i.e. additional email addresses, twitter feeds, Facebook, GitHub, Stackoverflow, etc..) to enhance the record. It looks like you can add a picture to your candidate records, but you have to do that manually. Workable does all of this automatically. Lastly, I wish I could create a record from the clipboard as oppose to creating a .pdf or .doc to import a resume. Sometimes I find a resume on a blog and I just want to copy it and paste it into Jobadder. And if I had to nitpick... I wish it was a little bit faster.
