The month my first hire uncapped a Form 5500 penalty I owed personally, at 68K MRR

A composite founder diary. Hiring one engineer moved our retirement plan from a capped IRS filing penalty into Title I of ERISA, where the daily meter has no ceiling and the liability is personal. The arithmetic between the correction programme and the exposure is about a thousand to one.

Flat vector diagram on off-white: a short warm sand bar above a terracotta bar roughly twice its length. A charcoal vertical bar about a third in crosses the terracotta bar and stops short below the sand bar. Four small pale grey squares sit just above the terracotta bar near its right end.

The month a payout feature made me a money transmitter at 65K MRR

A composite founder diary. At 65K MRR a banking partner asked whether client funds ever touched our balance. Nine days in the statutes turned up a federal felony that says your knowledge is irrelevant, an exemption written for somebody else, and a civil penalty of 10,556 dollars a day that the statute itself prints as 5,000.
