Last week, Loyal received what is likely the FIRST ever FDA blessing for a clinical study to test whether an aging drug extends lifespan & healthspan

In FDA parlance - "protocol concurrence" To market a drug, you must objectively prove to the FDA that it has the health benefit you claim.

I founded Loyal around the idea that the FDA would approve an aging drug for healthy lifespan extension itself, NOT any specific disease.

Today we are opening X-Thousand Dogs, our next canine aging study, to the dog-loving public!

We need dogs of all sizes + ages + breeds to participate

The goal: map out DNA structure change w age/environment/health & explore if these changes can be PREDICTIVE of future health We are giving away 2,000 23andme-style kits.

Pet parents swab their dog 2x (yay technical replicates!), return swab to Loyal, & give their dog the enclosed Wolfie-approved treat :)

We will return what we learn about your dog's health, aging, genetics

Aubrey de Grey is a sexual predator.

This is an open secret in the aging field. @LauraDeming & I are sharing our stories today so that women entering aging know this BEFORE interacting with Aubrey.

Allegations include sexual harassment & abuse, including against minors Aubrey and SENS nearly killed both of our aging careers before they began.

Laura has shared her story here: ldeming.posthaven.com/aubrey

I've raised one of the largest seed rounds ever for a female solo founder, for a weird, moonshot company that doesn't quite fit in most VC's pre-ordained view of the world ;)

I've written a behemoth post on how this round happened, my mistakes, and - most fun - the bloopers! My favorite lessons:

Don't try to learn all the patterns/social etiquette on your own. Find a generous founder or VC to walk you through it.

Don't be tempted to minimize timelines, $ to milestone, etc to satisfy the VC. You get labeled as an amateur + sets you up for failure

Hypothesis: it is easier to hire all-star employees in bio than in tech

1- No FAANG golden handcuffs.

The Pharmas pretty ubiquitously suck to work at, the HQs lack the bells and whistles of tech, and pay for junior people is easily matched by a startup 2- Less founder culture in bio.

Bad for creating new bio co's, but great for hiring. Scientists are much more likely to look for a job than try to start a company

Building a biotech company in Silicon Valley is amazing, but I quickly learned to not take common startup-isms at face value & to validate for myself that they translate over to building in bio. Many don't. Here's some differences I've noticed so far: celinehh.com/tech-vs-biotech & a few faves:

TECH: Rolling derisking, early signs of product-market fit
BIOTECH: Derisking comes in bursts over years (biological milestones), early signals less reliable

TECH: Outsourcing product development or engineering unadvisable
BIOTECH: Common to use contractors
