Is a PM's Record Measured by the Exit or by Survival? Musk's X Product Head Sold Two Hits — Both Were Shut Down

“Time to pass the torch and demote myself to my natural state: a poster.”

That’s what Nikita Bier wrote on August 5, stepping down as head of product at X. He took the job in July 2025, lasted a year and one month, and stays on as an adviser.

A man who ran product for a platform with hundreds of millions of users says his natural state is posting. You can read that as self-deprecation. You can also read it as unusually honest self-knowledge.

His record is strong, but strong in one particular way

Bier built two products before this.

One was tbh, an anonymous polling app that caught fire among American teenagers and sold to Facebook in 2017. The other was Gas, an anonymous compliments app — same audience, same explosion — sold to Discord in 2023.

Two startups, two exits. That record stands up anywhere in Silicon Valley; most people never manage it once.

TechCrunch added one line when reporting his departure: both apps were later shut down.

tbh went into Facebook and was killed. Gas went into Discord and was killed. Nothing he built is still running today.

Selling and surviving are two different objective functions

This isn’t nitpicking. It’s a question of what his operating system was calibrated for.

Teen social products have a well-worn playbook: find a mechanic that spreads inside a school, ignite it as fast as possible, and sell while the heat is still on. Every step of that playbook optimises for the exit — the growth curve has to be steep, the users have to be concentrated in a demographic an acquirer can recognise, and the product doesn’t need a story for its second year.

It actively discourages you from thinking about year two. Thinking about year two means retention, monetisation and content moderation, and all of those flatten the curve you’re about to show a buyer.

By that objective function, Bier scored full marks twice. The product being shut down was never his KPI — his KPI settled the moment the deal closed.

The trouble is that when this system leaves the startup environment, the scoring rubric changes.

Thirty new products in a year is itself the answer

Bier’s own summary of his year at X: 30 new products shipped, while “protecting the integrity of the town square.” X’s account adds that he rebuilt the feed, the Android client, DMs and notifications, and delivered X Money — the payments feature Musk had promised in 2024 and never shipped.

X Money is hard work, and landing it is real. So are the feed and DM rebuilds.

But “30 new products in a year” is a strange number for a platform that already has hundreds of millions of users.

A startup trying 30 things in a year is normal — you’re hunting for the mechanic that spreads, and the cost of a failed experiment is roughly zero. A mature platform shipping 30 new products in a year means most of them were never really raised. The hard part on a platform product has never been inventing features; it’s getting one feature to survive its first quarter, enter a habit, and not get crowded out by next quarter’s batch.

Casting a wide net for a hit and raising one thing into a habit are two different crafts. He is plainly world-class at the first.

So how should a product manager’s résumé be scored

That’s what I actually found myself thinking about.

The industry’s default is to score by exit: how many companies you sold, for how much, to whom. There’s logic to it — an exit is verifiable. It has a number, an announcement, a date. Unlike “retention,” it can’t be narrated into anything you want.

It has one side effect: it removes “did the product survive” from the evaluation entirely.

Scored by exits, Bier is two for two. Scored by survival, he’s zero for two.

Neither scoring is complete. Scoring only by survival would be unfair to a lot of people — products get shut down for reasons that have nothing to do with their founder. Big companies buy you for the people and the technology, not to keep the app running forever. tbh and Gas being killed is mostly on Facebook and Discord, not on Bier.

But scoring only by exit produces an awkward kind of career: a person can hold a genuinely impressive résumé while nothing he ever built still exists.

He answered it himself

Bier didn’t say he was off to build the next hit, and didn’t say he was returning to Lightspeed to invest. He said he was going back to posting.

That line is more honest than any retrospective. He knows what he is best at and enjoys most — spotting a gap in attention right now and turning it into a moment. Posting and building a viral app use the same muscle.

Running a platform that hundreds of millions of people open every day uses a different one.

What’s left

X has split the product lead across three people: Benji Taylor on design, Jonah Katz on iOS, Mridul Singhai over the product organisation. Splitting one person’s job three ways says something on its own — either that role should never have sat on one person, or X wants to play it differently.

As for how a product manager’s record should be scored, I don’t have an answer. I only know that when I next read the line “serial entrepreneur, two successful exits,” I’ll now ask one more question: are those two products still running?
