Atlassian is smaller than Microsoft.
We often pitch against solutions from Microsoft, IBM, SAP, Oracle, Adobe or Google. Compared to these companies the 5bn Dollar company Atlassian with its 2k employees is small and not yet as well known. Some companies think that this puts a risk on their decision for choosing an "underdog".
This solution is not enterprise ready.
There are a lot of players in the Atlassian ecosystem. Atlassian itself and more than 300 Atlassian partners and over 2100 add-ons for their products. One add on in the Linchpin suite comes from a vendor in Budapest, Hungary. Since when do you buy core IT infrastructure and software from Hungary? Some people feel that the diverse set of offerings and service providers makes it difficult to create a streamlined, reliable solution that is truly enterprise-ready.
We do not care about the budget and time.
Linchpin is a very cheap solution for bigger companies. Especially when you have more than 10k employees the advantages in license pricing are very high. If that is no argument or not important in your project, especially blue chip solutions (like Microsoft, IBM, ...) become more attractive.
This solution is not mobile ready.
We have a "mobile first" strategy and your solution is not fully available as a native app yet. So we cannot consider you as a relevant vendor.
