Growing pains of scale are evident right now, especially scaling ops to support rapidly growing membership and site footprint. Healthcare's a nearly impossibly difficult problem -- we can't yet solve it with tech alone and are having to bridge with more traditional solutions, which has led to a bit of wheel re-creation given the lack of healthcare industry experience in many parts of the organization (not all bad since it also helps us avoid falling into traditional healthcare traps). These are all solvable problems and not altogether surprising for a company at this stage, but worth calling out.
Also somewhat unsurprising given stage, but a number of internal functions are overloaded and overworked -- hopefully that's something more bodies can fix ASAP.
Some (especially clinicians / front-line clinical team members) may struggle with long(er) hours, rapid pace of change, style of practice, etc. that are more suited to the traditional "startup" world than healthcare -- continuing to hire at all levels such that those expectations are clear from the beginning and are tested for during the hiring process will be key.
