The main benefit I see in using knockrIs was their ability to provide our organisation's consultants/team members who are not native English speakers (which we have) access to quick language learning tools at no additional cost through an app called 'learnout'.
This has been really helpful for them to be able to conduct business meetings more efficiently than they had previously due to lack of communication experience - especially within this particular industry which speaks multiple languages! Also it allows me to keep track of what my team member learns via learn out and share progress reports back up the line for coaching purposes. There isn't anything too negative about knockingRIthese services either but there could potentially be some improvements made if need arises such as being easier to navigate when you first log into your account - maybe include sign-up process instructions better so people don't get lost trying.
