Marc Andreessen recently shared a line from Sean Parker that every founder knows in their bones:
“Being an entrepreneur is like getting punched in the face over and over again. Eventually you start to like the taste of your own blood.”
It sounds dramatic until you’ve lived it.
The part that doesn’t get talked about enough is the social denial. Not just rejection—denial. “No, this won’t work.” “No, I won’t join.” “No, I won’t take the meeting.” A wall of it. For years.
And then when something finally breaks through, the narrative gets rewritten overnight. Suddenly it was “inevitable.” Suddenly everyone always believed in it.
Marc calls this the retcon—and he’s right. Nobody who was actually in the room remembers it that way.
What resonates most with me is his point about ego strength. Not ego as arrogance. Ego as the structural integrity to absorb thousands of “no’s” without collapsing. Most people—smart, capable people—get shaken out. Not because the idea was wrong, but because the social cost of being early is brutal.
If you are in the middle of the punching right now: it doesn’t get easier. You just stop flinching and keep going. No matter what.
#FDA clears @UltrasoundAI Delivery Date #AI tool to predict delivery date - a cloud-based software as a medical device #SaMD designed to determine a predicted delivery date from standard ultrasound images https://t.co/c6r5fu5Ncr
New from the #FDA:
The federal agency has granted De Novo clearance to Ultrasound AI's Delivery Date AI technology, a cloud-based Software as a Medical Device (SaMD) designed to predict a delivery date (PDD) using only standard #ultrasound images. #Pregnancy#AI
Data previously published in The Journal of Maternal-Fetal & #Neonatal Medicine were peer-reviewed and supported the clearance.
Full details on the new technology: https://t.co/z4Unozgthu
We spoke with Raquel Dardik, MD, chief medical officer at @UltrasoundAI, about today's #FDA clearance of the Delivery Date #AI technology, which analyzes #ultrasound images to predict a delivery date.

We received FDA De Novo authorization for Delivery Date AI!
FDA clears thousands of devices each year through the 510(k) pathway, but grants far fewer De Novos—typically only dozens annually.
De Novo isn’t the easy path. There’s no legally marketed predicate to point to. You have to demonstrate safety and effectiveness on the technology’s own merits—and help establish the device type’s performance expectations and controls.
I’m proud of the team, but more importantly, I’m grateful for the clinicians who challenged us, tested the system, and pushed us to make it better. That rigor is what made this possible.
Regulatory milestones matter because trust matters. This isn’t about speed. It’s about proper validation so clinicians can confidently incorporate technology into clinical practice.
There’s still a lot of work ahead, but this is an important step toward giving clinicians clearer information to support pregnancy care decisions.
Thank you NBC 9News for having me on this morning!

As a founder, one of my jobs is to determine yearly bonuses. This year I got to thinking about it and realized that giving cash is so impersonal and it implies I wasn't willing to take the time to give a real gift that shows how much our employees are valued. So this year instead of potentially being rude and giving out cash bonuses I found this really great service that sends a jelly every month to each of our employees. A gift that keeps on giving the whole year around.

Preterm birth affects one in ten babies in the U.S., yet early detection remains one of the biggest gaps in maternal care. In a new @PBS NewsHour segment, families shared their experiences with premature birth, and Robert Bunn spoke with @AliRogin about why predicting these outcomes has historically been so difficult, and how AI can change that.
Ultrasound AI’s technology analyzes millions of ultrasound images to identify subtle patterns linked to delivery timing, providing clinicians with earlier and more precise insights than traditional methods allow. This includes identifying first-time mothers who may be at risk but would otherwise go unnoticed.
The goal is to help care teams prepare, intervene when possible, and ultimately improve outcomes for mothers and babies.
We’re grateful to PBS NewsHour for spotlighting this issue and for elevating the voices of families who have lived it.

Today is World Prematurity Day — a reminder that preterm birth is not a rare edge case, but a daily reality for millions of families and the clinicians who care for them.
Preterm infants put enormous pressure on health systems: complex decisions, limited time, and incomplete information. That’s exactly the environment where better tools — and especially better diagnostics — matter.
At Ultrasound AI, we’re focused on using AI to:
• Support earlier risk detection in pregnancy
• Give clinicians clearer signal from noisy ultrasound data
• Help standardize care so outcomes are less dependent on where a patient happens to be born
If you work in OB, MFM, radiology, or the NICU, We would be interested to hear: where does the current workflow break down most for preterm risk assessment or the care of preterm babies?

@UltrasoundAI secures its 6th issued patent, protecting methods to determine clinical values directly from ultrasound and other medical imaging. A step forward in making predictive imaging scalable and accessible.

Our founder Robert Bunn to be part of Imagination in Action: The Next Revolution of AI this week. On Sept 8 at 1:30 PM (Builder Stage, Google MP6, Sunnyvale) He will join the “AI Transforming Healthcare” panel to share how we’re using AI on standard ultrasound images to predict the delivery date and preterm risk as early as 6 weeks—so clinicians can intervene sooner and families have a better chance at healthy outcomes.
Grateful to the organizer John Werner and community bringing together builders, researchers, and investors who believe AI should translate into real-world impact. We are excited to learn from fellow speakers, meet founders in the Startup Spotlight, and connect with anyone passionate about responsible, human-centered AI in health.
He will be at Google on Sept 8 and Stanford on Sept 9, and would love to connect—DM him or say hello after the session.
Let’s turn imagination into action!

This September, we honor Ovarian Cancer Awareness Month by amplifying a simple, urgent message: awareness saves lives.
Ovarian cancer can be hard to detect early. Know the common symptoms—bloating, pelvic or abdominal pain, feeling full quickly, and urinary urgency/frequency. If these are new and persistent, talk to a healthcare professional.
At Ultrasound AI, our mission is to help clinicians make earlier, more confident decisions through accessible imaging and responsible AI. We’re committed to advancing women’s health and supporting equitable access to high-quality care.
Join us: wear teal, share this message, support patients and caregivers, and encourage loved ones to stay on top of their health. 💚
