Hi friends 👋 ,
Happy Friday and welcome back to our 171st Weekly Dose of Optimism!
I love sending the Dose on weeks like the one we’ve had in the markets this week. We started this thing in the middle of the last bear market to remind people that there is so much good stuff happening that’s going to take longer than a quarter to pay off, and this week, we have a lot of great reminders: epigenetics to fight aging, Bezos tackling real-world AI, Google DeepMind continuing to cook, robots that will do our chores, and a company making it rain.
Let’s get to it.
Today’s Weekly Dose is brought to you by… Stripe Startups
Every venture-backed company — yes, you — should work with Stripe Startups.
Stripe’s mission is to increase the GDP of the internet, and it’s working. Last year, 1.3% of global GDP flowed through Stripe, over $1.4 trillion and growing. 78% of the Forbes AI 50 use Stripe’s financial infrastructure to monetize faster, experiment with pricing, and grow revenue.
As I wrote in my original Deep Dive, Stripe’s strategy from the earliest days has been to make it as easy as possible for startups to begin accepting payments, and then grow with them as they get really big. Little companies become big companies become public companies.
With Stripe Startups, they’re making it even easier.
Stripe Startups is the company’s new program designed to support early-stage, venture-backed businesses as they build, iterate, and scale. Founders enrolled in Stripe Startups get access to credits to offset Stripe fees, expert insights, and a focused community of other founders building on Stripe.
You’re going to use Stripe anyway. Get the white-glove experience.
(1) General Control Comes Out of Stealth to Make Epigenetic Medicines for Aging

General Control seeks to develop compounds that can alter numerous genes in the human body to create lasting effects such as increased muscle mass or better liver function. If the company can do what it hopes, General Control would produce aging therapies far more potent than anything available today.
I’m still not sure whether I want to live forever, but I certainly want to stay healthier, stronger, and smarter as I age. Fortunately, Lada Nuzhna is on the case.
Lada is awesome. I spoke to her a few months ago and saw her present at the
