In this brief video, Katie Mullen recounts her initial skepticism about the startup Rhythm, which sends monthly at‑home blood collection kits, questioning its legitimacy. She describes traveling to Omaha to visit the company's large laboratory, observing a sizable team of scientists and the testing workflow. She notes that test results are returned within 48–72 hours, confirming the service’s reliability. After seeing the operation firsthand, she declares herself a believer, while also sharing a personal aside about working late nights in June.

When I first started doing Rhythm, I was skeptical. I was like, what is this startup mailing me blood kits every month? Like, how do I know that this is legit? Well, it's legit. Look at this. This is a huge lab with a huge team of scientists running these tests. This is how you get your test back in 48 to 72 hours. I've seen it with my own eyes. I'm a believer. Sometimes all I think about is you late nights in the middle of June.
