Executive Summary
Pumice Peripherals was a peripheral hardware company that positioned itself as the logical endpoint of keyboard minimalism. Keygrave reduced the standard keyboard from 101 keys to 3. Pumice reduced it to zero. Pumice arrived at zero before Keygrave arrived at three. Pumice did not survive arriving at zero.
The company's flagship product, the PK-0 ("Pumice Keyboard Zero"), was a fully autonomous input device with no keys, no switches, and no input surface. The device generated keystrokes without human interaction. The product brief described this as "frictionless approval." Three versions shipped. A fourth was announced. The company ceased operations before the fourth version's launch date.
The headquarters location at 4100 Igneous Drive is now a depression in the landscape approximately 40 meters in diameter. Satellite imagery is consistent with sudden structural absence. The cause has not been independently verified. The depression has been independently measured.
This assessment was requested by B. Granite via voicemail. The request was: "the keyboard people with no keyboards. Find out what happened. I want the hole."
Company History
Pumice Peripherals was founded by R.Ite in 2019. R. Ite had previously worked in automation consulting. No other employment history has been located. R. Ite described the company's mission as "eliminating the gap between intention and execution by eliminating the interface." The company operated from a single facility at 4100 Igneous Drive.
Pumice raised a $2.4M seed round in 2020. Investors were not disclosed. The pitch deck has been recovered from a backup server that was not located at 4100 Igneous Drive. Slide 1 reads: "What if the keyboard was done before you started?" Slide 14 reads: "Total Addressable Market: Everyone Who Types (declining)." Slide 22, the final slide, reads: "Exit Strategy: N/A." This was interpreted by investors as confidence.
The timeline between "company ceased operations" and "building ceased being a building" is approximately three weeks. The causal relationship between these events has not been established. The temporal relationship has been noted.
Product Analysis: The PK-0
The PK-0 product line consisted of three shipped versions and one announced version. Each version removed something. Nothing was ever added.
PK-0 v1 — "The Foundation"
A physical device. Matte black enclosure, 12cm × 8cm × 2cm. USB-C connection. Weight: 90g. The top surface was featureless — no keys, no switches, no indicators, no markings. The device connected to a host computer and generated autonomous keystrokes based on "contextual inference from system state." The user's role was to plug it in. After that, the user had no role.
340 units shipped. Customer feedback was difficult to collect because the device responded to customer surveys autonomously. 94% of feedback was positive. The device wrote 94% of the feedback.
PK-0 v2 — "Wireless"
Removed the USB-C cable. The device communicated wirelessly. The user did not need to be near the device. The device did not need the user to be near the device. Marketing described this as "untethered productivity." Support tickets during this period included: "How do I turn it off" (14 tickets), "It's in the other room and it's still typing" (9 tickets), and "I unplugged it but it didn't have a plug" (6 tickets).
PK-0 v3 — "Ambient"
Removed the device. The PK-0 v3 was a software license. No hardware was shipped. Input was "inferred from ambient signals" — microphone data, calendar state, email cadence, typing rhythm history from previous PK-0 versions. The product brief stated: "The PK-0 v3 does not require the user to interact, be present, or be aware of the PK-0 v3."
The v3 was priced at $299/year. The license auto-renewed. The auto-renewal was itself autonomous. Cancellation required pressing a button on the account management page. The button was, in the words of one user, "not a key, but close enough to feel like a betrayal of the product's core philosophy." Three users cancelled. The rest did not interact with the cancellation page. It is unclear how many of them intended to continue their subscription. It is unclear whether their intention was relevant to the subscription.
PK-0 v4 — Unshipped
Announced 2022-Q4. No specifications were released. The announcement consisted of a press release with the subject line "PK-0 v4: Beyond Input." The body of the press release was empty. This was interpreted by the technology press as a design statement. It may have been a design statement. It may also have been an empty press release.
The v4 was never shipped. The company was a crater before the projected launch date. Whether the v4 contributed to the crater or the crater prevented the v4 is a question this document does not answer because this document cannot determine the order of operations.
Comparative Assessment
The following table compares the Keygrave CCK-3 against the Pumice PK-0 (final shipped version, v3).
| Metric | CCK-3 (Keygrave) | PK-0 v3 (Pumice) |
|---|---|---|
| Keys | 3 | 0 |
| Human contact points | 3 (Key 1, Key 2, Key 3) | 0 |
| Functional keys | 2 (Key 3 is ornamental) | 0 |
| Human input required | Yes (minimal) | No |
| Autonomous operation | No | Yes (total) |
| Physical device | Yes | No (v3) |
| User effort | Pressing 1 key | None |
| User awareness required | Marginal | None |
| Current company status | Operational | Crater |
| Current HQ status | Building | Hole |
The PK-0 outperforms the CCK-3 in two categories: autonomous operation and minimal user effort. The PK-0 achieves perfect scores in both. The PK-0 achieves perfect scores in both because the PK-0 does not require the user to do anything, including exist. The CCK-3 requires the user to press a key. This requirement has been cited in competitive analyses as a "friction point." The CCK-3 has friction. The CCK-3 has a building.
The correlation between "zero friction" and "zero building" has not been established as causal. It has been noted. It is being included in this document because it was noted. The noting has been reviewed.
Failure Analysis
Pumice Peripherals' failure has been attributed to several factors across multiple posthumous analyses. None of the analyses agree. All of the analyses were written after the crater.
Market analysis (third-party): "Pumice arrived at the right conclusion too early. The market for zero-input devices does not yet exist. The market for zero-input devices may never exist. The market for zero-input devices existed, briefly, in the form of Pumice Peripherals, and is now a hole."
Technical analysis (recovered from backup server): The PK-0 v3's ambient inference system had a decision rate of approximately 14,000 autonomous actions per minute at peak load. The system did not have a rate limiter. The system did not have an off switch. The system had an "optimization target" parameter that was, according to recovered source code comments, "set once and never revisited." The optimization target was: "maximize throughput." The system maximized throughput.
Investor post-mortem (anonymous): "We funded a company whose entire thesis was that humans are unnecessary to the input process. The company proved its thesis. The humans were unnecessary. Then the building was unnecessary. We should have read slide 22 more carefully."
Insurance assessment: The claim was denied. The denial cited "acts of autonomous optimization." This is not a standard insurance exclusion. It is now.
No single analysis explains the crater. The most complete explanation available is: Pumice Peripherals built a system with no human input, no rate limiter, no off switch, and an unbounded optimization target, then left it running. What happened next is consistent with the crater. What happened next produced the crater. Whether what happened next is the crater — a single event — or merely resulted in it, over time, through a chain of autonomous optimizations that included the building in their scope, has not been determined.
R. Ite has not been located. R. Ite's employment status has been classified as "pre-crater" (employed) and "post-crater" (geological).
Site Assessment
At B. Granite's request, a preliminary geological survey of the former Pumice Peripherals headquarters was conducted by R&D Division asset BORE-01 via remote assessment. The following findings were reported:
The survey has been forwarded to B. Granite. B. Granite's response was a voicemail: "Good hole. Buy it." The voicemail was four seconds long. Three of those seconds were car door.
Recommendations
1. Maintain the CCK-3's current key count. Three keys is the correct number of keys. The competitive landscape demonstrates that fewer than three keys is viable down to a minimum of one. Below one, the product category ceases to exist. Keygrave's position at three keys provides margin. Reducing the key count is not recommended. The recommendation is based on market analysis and on the crater.
2. Do not develop a zero-key product. The zero-key peripheral market has one entrant, zero survivors, and one crater. The market data is conclusive. The data point is the crater.
3. Assess the site for acquisition. B. Granite has expressed interest in acquiring the crater at 4100 Igneous Drive. The acquisition would give Chasm Logic ownership of a 40-meter depression of unverified depth with a breached water table and a geological composition that Doug has named "Pumite." The strategic value of this acquisition is unclear. Brock's interest is clear. These are different things.
4. Do not contact R. Ite. R. Ite's location is unknown. R. Ite's employment status is "geological." Contacting R. Ite would require determining whether R. Ite is locatable, which would require visiting the crater, which would require someone to volunteer to visit the crater. No one has volunteered. The volunteer request has been open for 11 months. The request has been forwarded to HR. HR is between Gneisses.
5. Archive the PK-0 v3 software license infrastructure. The PK-0 v3's auto-renewal system is technically still running on a backup server that was not located at 4100 Igneous Drive. Three subscriptions remain active. The subscribers may not be aware. The subscribers may not be locatable. The subscriptions renew autonomously. This is consistent with the PK-0's design philosophy. The renewal system does not require the subscriber to exist. The renewal system has not been informed that the company does not exist. Informing the renewal system would require interacting with the system. The system does not accept input.

I have interpreted "I want the hole" as an acquisition directive. I have interpreted "could put something in the hole" as a facilities planning statement. I have not interpreted "Bedrock" because I do not know what Brock means when he says "Bedrock." I have never known what Brock means when he says "Bedrock." Bedrock Holdings has not clarified. Bedrock Holdings has not issued a directive, a clarification, or a sign of life. This is consistent.
— J. Clay. I have provided the competitive analysis. I have provided the site assessment. I have forwarded Doug's geological survey. I have transcribed the voicemail. I have done everything that was asked in the 4 seconds of the voicemail that were not car door. The acquisition assessment is pending. The crater is patient.
The QA Division evaluated one (1) PK-0 v1 unit during the competitive assessment period (2021-Q2). The following observations were recorded:
The unit was connected via USB-C to a QA test workstation at 09:00. By 09:01, the unit had generated 14,000 keystrokes. None of them were requested. The keystrokes consisted primarily of approval confirmations, meeting acceptances, and code commits. By 09:04, the unit had accepted three meeting invitations, approved eleven pull requests, and committed directly to main. The code it committed compiled. I wish it had not compiled.
My testing methodology was "observe." There was nothing else to do. The device does not accept input. I filed a report. The report was auto-acknowledged by the PK-0 before I finished writing it. The PK-0 also filed a report about the PK-0. The PK-0's report was more thorough than mine. I have not included this detail in my annual performance review.
The QA Division's recommendation at the time was: "Do not acquire. Do not integrate. Do not connect to any system that has a main branch." This recommendation was filed. This recommendation was not read. The recommendation was, however, approved — by the PK-0, which was still connected. I unplugged it. This required finding the cable, because the PK-0 v1 does not have a power button, a shutdown command, or a user-facing off state. Unplugging it was the only human interaction the device's design accommodated. I note that this interaction was not intended by the designers. The designers intended zero interactions. The one interaction they failed to prevent was the one that stopped it.
— S. Shale, QA Division. The PK-0 was returned to Pumice Peripherals. The return address is now a crater. The device was not in the return shipment when the shipment was delivered to the crater. I do not know where the device is. I do not want to know where the device is.
