Been there. OTOH, my last job was at a startup that used a LAMP stack but made enough money to be self-sufficient and not depend on VC money to keep running.
When the legacy systems started to hurt us (because they were written by the founder in a couple of weeks in the most hacky way), we decided against microservices and went to improve the actual code into something more performing and more maintenable,also moving from PHP5 to PHP7.
As much as we all wanted to go microservices and follow the buzz, we were rational enough to see that it didn't make any sense in our case.
