Anyone with experience with Merge.dev? i will not promote

Context first: We're a vibe coding platform and have been repeatedly attacked by Merge's AE to use their tools. They problem they want to solve is one we solve internally and it's my vision that comparable platforms should: * Route users to the appropriate models (e.g. don't use the most advanced ones for trivial things) * Spend caps/failovers What I don't love: * When I am not responsive, they (in particular, one of the crazy founders) have gone through invasive channels to get to my CEO, our investors, and sends quite rude messages to our team to ignite a response * When I listen to the founder's podcast, she drops F bombs and frankly quite unprofessional anecdotes, like figuring out pricing on the fly * Out of the 12 logos they have on their website I have managed to speak to 2 exec buyers through our VC network, and both seem to have wildly different pricing Asking for help: Does anyone (even smaller start-ups) have experience working with their team? I'm most interested in the model routing offering and I want to figure out: * How it might be better than our control plane product (we had a relatively large team setting this up and is stable in running with a reduced maintenance team) * I need to answer to my CEO why we are or are not trialling them as a result of their persistent and unhinged outbound to all levels of my org above and below me * Not able to find community inputs on this
