Mediocre 401k matching. They match up to 25% of deferrals up to 8% of compensation, which is a complicated way of telling you that the highest they'll ever contribute is 2% of your salary - and only if you're contributing 8+% of your own salary. That is significantly lower than the average employer contribution and makes it very hard to feel secure about your future. Keep in mind this goes for all EverCommerce subsidiaries, too.
Their salaries are also behind; it's incredibly difficult to get a significant raise, even if you're completely overworked.
