The guy who made Stories left to kill the feed
Owensboro, Kentucky is not where most Silicon Valley founders come from. There are no incubators there, no demo days, no TechCrunch coverage. It is a river city in western Kentucky where bourbon gets made and time moves differently. Nathan Sharp grew up there. Then he went to Harvard, then Dartmouth's Tuck School of Business, then Google, then Instagram - and somewhere along the way he became one of the most consequential product minds in consumer social.
In 2016, Sharp was the product lead on a small Instagram team tasked with a response to Snapchat's disappearing Stories format. The feature they shipped - Instagram Stories - became one of the most-used products in the history of the internet. Over a billion people use it. Sharp built it. Then he went back to his desk and kept building things at Meta for six more years.
He left in May 2022. Not because he was pushed out. Not because of drama. He left because he had a better idea - and the only way to build it was to start over.
"Social media has been around so long that we've forgotten to ask: What should we want from this? How should it work? How should it make me feel?"
- Nathan Sharp, 2025The Nifti detour
Before Meta, before Instagram, Sharp ran a startup called Nifti. He co-founded it with a Tuck classmate right out of business school - the idea was simple and audacious in equal measure: set a price target on any product from any retailer and wait for it to hit. Priceline for everything. The team of seven worked out of Boston's North End. They raised $800,000 from Google Ventures. They won the top prize at the Dartmouth Ventures conference. They ran it until 2015.
Nifti didn't become the category-defining commerce platform Sharp envisioned. But it taught him something important: what it costs to build a product from nothing. The patience it requires. The gap between a good idea and a great execution. When Instagram came calling, he was ready in a way that most career PMs simply aren't.
One telling detail from those Nifti days: Sharp raised $50,000 through Upstart - an income-share investment platform - to cover student loans while he built the company. That's not a typical VC move. It's a founder move. It says something about how Sharp thinks about commitment.
