Unit Tests are invaluable in writing more quickly difficult features. You can make sure that your existing behaviour is not broken by fixing a bug or adding more functionality. Every day you spend fixing bugs because you didn’t want to write proper unit tests reduces your chances of getting that next founding round. If you write trivial code the tests are obviously superfluous, but you should ask yourself what is the added value of your product if you only write trivial code.
