How realistic is it to launch an MVP in the US that only supports Android (I will not promote)

I am part owner in a start up that is a B2B SaaS company and the software has a mobile app. My business partner wants to launch MVP on only android devices and I want to launch with both android and IOS. As a side note our mobile is a hybrid app so it essentially one code base for IOS and Android and it is all through a webview. The problem is that my partner (who is the software engineer) is saying that finishing the mobile app would be much easier and faster in Android compared to apple. My argument is that just under 60% of all mobile devices are IOS in the US (which is where our customers are located). So in that sense if you have a company with 10 users and it is a mix of Android and IOS it would be difficult to get them as a customer. If this app targeted just single consumers then I think there would be a much stronger argument for going Android only. But since it is B2B and I think that either finding a business that is purely on android or convincing a business to become purely android would make selling this software about 10 times more difficult. Looking for thought's and opinions on this.
