Why Dot AI shut down
Dot was an iOS-only AI companion app from New Computer, built by its two co-founders — Sam Whitmore and ex-Apple designer Jason Yuan — launched June 2024 and pitched as a friend that gets more personalized over time [3P]. The shutdown was announced September 5, 2025, and the app stayed operational only until October 5, 2025 [3P]. Stated cause, from the founders' own letter: their "Northstars as founders had diverged" and they wound the company down rather than compromise either vision [FDR]. On the day of the announcement, TechCrunch cited Appfigures data showing 24,500 lifetime iOS downloads against the company's claimed "hundreds of thousands" of users [3P].
Timeline
- 2024-06Dot launches on iOS. Two co-founders on the record: Sam Whitmore and ex-Apple designer Jason Yuan, operating as New Computer. No Android version is ever shipped. [3P] source
- 2025-09-05Shutdown announced. TechCrunch reports the same day that New Computer will keep Dot operational until October 5 so users can export data. No acquirer is named. [3P] source
- 2025-09-05Founders' farewell letter posts at new.computer. Stated reason: their "Northstars as founders had diverged" and "rather than compromise either vision, we've decided to go our separate ways and wind down operations." The letter also says the company "spent the last year exploring how we could expand from personal intelligence to social intelligence," and repeats the claim that Dot grew "to help hundreds of thousands of you."

- 2025-09-05Traction gap goes on the record: app-intelligence provider Appfigures, as cited by TechCrunch, measures 24,500 lifetime iOS downloads since launch — versus the company's claimed "hundreds of thousands" of users. [3P] source
- 2025-10-05Final operational day. Data export available until this date via settings, "Request your data." App goes dark; roster logs death month as 2025-10, 16 months after launch. [3P] source
- 2026-06-27Filed on our roster as graveyard, cause logged: no moat built — the founder split detonated first. Traction field logged as 24k tracked downloads versus claimed hundreds of thousands. [OBS]

EVIDENCE GRADE: A — primary sources on file.
Cause of death — our read
Cause filed on the roster: nothing built — the internal split blew up first. The record supports the filing. Dot shipped June 2024, iOS only, built by its two co-founders: Sam Whitmore and ex-Apple designer Jason Yuan [3P]. Sixteen months later, on September 5, 2025, the founders posted a wind-down letter. Stated reason, in their own words: their "Northstars as founders had diverged" and "rather than compromise either vision, we've decided to go our separate ways and wind down operations"; the letter notes the company spent its final year "exploring how we could expand from personal intelligence to social intelligence," but does not state which founder held which vision [FDR]. No acquirer was named [3P].
The traction ledger carries the second half. The company claimed "hundreds of thousands" of users, a figure repeated in the farewell letter itself [FDR]. Appfigures — the app-intelligence provider cited by TechCrunch in its shutdown report — tracked 24,500 lifetime iOS downloads from launch to the announcement [3P]. No Android build existed, so the iOS count is close to the whole install universe [3P]. That is roughly one order of magnitude between the stated figure and the metered one.
[INF] Our read: the public number was doing marketing work, not accounting work. And a product carrying ~24.5k lifetime installs after 15 months gave neither founder an economic reason to concede the vision fight — thin, unverifiable traction lowered the cost of walking away. The split was the trigger; the missing user base was the load. Logged accordingly: death by founder divergence, with nothing on the books heavy enough to hold the company together.
The lesson on file
Roster lesson as logged: do not raise, and do not publish user numbers, before growth is verified. The transferable rule — any figure stated in public will eventually be reconciled against a third-party meter. Appfigures-class trackers publish independent install estimates, and the press runs the comparison on the day of death; Dot's obituary led with 24,500 versus "hundreds of thousands." Second entry: a two-founder company whose only asset is a shared vision carries a single point of failure that no design pedigree fixes. When the numbers are too thin to arbitrate a strategy dispute, the dispute ends the company. Carried forward: instrument traction first, publicize second, and audit founder alignment as a metric, not an assumption.
The reopen clause — what would change this verdict
Does 'the internal split blew up first' hold as the primary cause?
NEXT SIGNAL: Either founder shipping a companion successor, or a first-party postmortem that contradicts the split account.
A READ WITHOUT A NEXT SIGNAL IS JUST AN OPINION — THIS ONE IS FILED IN ADVANCE, LIKE EVERYTHING ELSE ON THE DESK.
What to use instead
Dot is the only entry on the books in the AI-companion track; no direct live replacement is tracked. The nearest tracked track is AI memory/context layer, where Mem0 (r021), Letta (r022), and Supermemory (r023) are live — the "remembers you over time" premise survives there in developer-infrastructure form.
