Faultline
An incident agent that learns every production failure across its customers, then fixes yours.
Faultline runs as an on-call agent inside a large company's production environment: it reads traces, logs and deploys, reproduces the failure in a sandbox, and proposes or applies the fix.

Test it before you build it
$1,200 · 6 weeks · 20 prospects
For under $1,200 and six weeks, prove both halves of the thesis on 20 US fintech SRE leaders: that a meaningful share of their real incidents match cross-customer failure signatures, and that they will pay $5,000 up front and sign a data-sharing addendum for a shadow-mode pilot.
1Focus group: who and where
SRE manager, director of reliability or head of platform at a US fintech with 200-2,000 engineers running a large Kubernetes estate, whose on-call rotation paged more than 20 times last month and who owns the incident tooling budget
where to find 20 · LinkedIn Sales Navigator filter on titles 'SRE manager', 'director of reliability', 'head of platform engineering' at US financial services companies with 200-5,000 employees; the Rands Leadership Slack, r/sre and r/devops for warm threads; SREcon (USENIX) speaker and attendee lists for named outreach
2Sell first, build later
A 90-day read-only shadow pilot on your three noisiest Kubernetes services: every incident triaged to root cause within 4 hours, graded weekly against your on-call's own conclusion, with a signed anonymized-signature data-sharing addendum, starting on a named date
the ask · $5,000 per pilot invoiced up front, credited against $200 per correctly triaged incident at conversion
a real yes · A real yes is the $5,000 invoice paid plus the data-sharing addendum signed with a dated start and three named services. 'On-call is killing us' sympathy, unpaid shadow access, and security questionnaires with no PO behind them do not count
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Postmortem corpus audit
$100 · 14 days
Ask 12 SRE leads for their last 10 sanitized postmortems under NDA. Hand-classify each incident: dependency, runtime or infrastructure version failure that would match a shared signature, versus idiosyncratic business logic. Deliver each lead a scorecard comparing their mix to the anonymized pool. This is the corpus thesis tested with zero code.
keep going if · 7 of 12 leads hand over postmortems, and at least 30% of the roughly 100 incidents fall into shared-signature classes
2. Per-incident pricing page
$400 · 14 days
One-page site selling incident response as an outcome: 'Shadow-mode on-call agent, $200 per correctly triaged incident, read-only for 90 days, you grade every call.' Drive 100 named Sales Navigator prospects to it by email; the CTA is a 30-minute triage-review call, not a signup.
keep going if · 6 of 100 emailed prospects book the call
3. Data-sharing addendum test
$300 · 21 days
Send the 12 audited prospects a two-page addendum permitting anonymized failure signatures (library, runtime and infra versions, no payloads, no customer data) to enter the shared corpus, and ask them to route it past their security or legal contact. Count redlines as engagement, flat refusals as the risk materializing.
keep going if · 5 of 12 say they could sign it as written or return redlines rather than refusing outright
4. Paid shadow pilot pre-sale
$200 · 21 days
Offer every audited prospect a 90-day read-only shadow pilot on their three noisiest services: the founders hand-triage incidents within 4 hours using the audit corpus and a sandbox, graded weekly against the human on-call's conclusion. $5,000 invoiced up front, credited against future per-incident pricing.
keep going if · 2 of 12 pay the $5,000 invoice with a dated start and named services
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$5,000
per prospect, refundable
how · A paid design-partner pilot invoiced up front: $5,000 via Stripe invoice paid by ACH against a one-page order form plus mutual NDA plus the data-sharing addendum, signed by the director of reliability or VP of engineering set up: Stripe Invoicing ↗
what it reserves · One of three design-partner slots, the $200 per-incident price locked for 12 months, priority coverage of their specific library and runtime versions in the signature index, and a committed start date
refund · Refunded in full if the agent triages fewer than 50% of graded incidents correctly in the first 60 days of shadow mode
target · 2 paid pilots from 20 conversations within 6 weeks
Go: build it if
2 paid $5,000 pilots with signed data-sharing addenda, at least 30% of audited incidents in shared-signature classes, and 5 of 12 prospects willing to sign or redline the addendum
Kill: stop if
Under 20% of audited incidents match shared signatures (the corpus never compounds), or 0 paid pilots and fewer than 3 of 12 willing to engage with the data-sharing addendum after the free audit

The idea in full
- What
- Faultline runs as an on-call agent inside a large company's production environment: it reads traces, logs and deploys, reproduces the failure in a sandbox, and proposes or applies the fix. What makes it different is the corpus behind it, a cross-customer index of failure signatures keyed to exact library, runtime and infrastructure versions, so a crash first seen at one bank is diagnosed in seconds at the next. Deployment starts in shadow mode for a long time, with forward-deployed engineers, and write access is earned after years of correct calls.
- Why now
- HyperProbe (yc S26) is pitching 'your coding agent writes code, now let it fix prod too' and Superlog (yc X26) is selling self-healing software, while Leaping (2024) died trying to automate bug resolution without a failure corpus; the corpus is the part that has not been built. Federal money is also moving here, with an NSF I-Corps award for an Automated AI Reliability Evaluation Platform.
- Wedge: first customer and entry point
- One US fintech with a large Kubernetes estate and a burnt-out on-call rotation: read-only shadow mode on their three noisiest services, priced per incident correctly triaged.
- Path to 100x
- Observability and incident management is a $10-100B market, and the compounding asset is failure signatures: every customer on the same versions of the same dozen popular libraries makes diagnosis faster for all of them, so the largest corpus wins most deals and the second-largest is structurally worse. A category is born when incident response is bought as resolved incidents rather than dashboards.
- Ceiling
- If most incidents turn out to be idiosyncratic business logic rather than shared dependency failures, the corpus stops compounding and this is a $100M ARR tool.
- Closest real companies, as the generator saw them
- HyperProbe and Superlog both attack production repair per customer; Faultline treats the failure corpus as the product and shares diagnosis across customers, which neither does. Leaping (graveyard) attempted bug resolution before there were agents able to reproduce failures in a sandbox.
- Main risk
- Enterprises refuse to let failure telemetry contribute to a shared corpus, and the network effect never starts.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
5/5
Cross-customer failure signature corpus is exactly the compounding data moat that makes the largest player structurally unbeatable in a $10-100B market.
Bootstrapper
1/5
Shadow mode with forward-deployed engineers and write access earned over years is a funded-enterprise game, not a bootstrapped one.
Operator
3/5
Burnt-out on-call is a real budgeted pain, but years of shadow mode before write access means the fintech pays for a promise, not a fix.
Technologist
5/5
Sandbox reproduction plus a cross-customer failure-signature index keyed to exact library versions is deep engineering whose accuracy compounds with every incident.
Risk
2/5
The cross-customer failure corpus needs banks and fintechs to share production telemetry, a consent and data-protection dependency the card admits may never start.
trends
2/5
Cross-customer failure diagnosis was an AIOps pitch long before 2025, and the only dated evidence is a roughly $50k NSF I-Corps award.
