DFM may be a nice lens to look at positioning this through IMO. It's thoughtfully designed around the larger workflow which more archaic (jab jab) tools don't understand or ignore. Honestly I love Trello but wouldn't give it the time of day in your positioning. Just emphasizing the depth of expertise and broad perspective on daily/weekly individual/team workflow that made your tool possible will, without saying it, be positioning you agains the anti-pm tool genre of pm tools (like Trello). Combine that with some talk about "delightful UX" (snark snark, you suck Jira!) and "modern, robust infrastructure with insane performance" (lol Asana you also suck!). Just thinking out loud but seriously positioning against Asana, Jira, Shortcut, etc should be as easy as saying, in other words, "brainless, terrible user experience, and buggy" (all of which are true and everybody knows it).
