Ripcord sits between the agent and the tools it uses. It stops the dangerous actions, makes the rest reversible, and records everything that happened. One line of config, any agent, any lab.
At TensorSource I ran operations. I wanted agents on the invoice queue, on support, on the marketing sends: the productivity was sitting right there. Our CTO blocked it: one wrong payment, one wrong mass email, one customer table pasted into a prompt, and the damage outruns a year of savings.
He wasn't wrong. Nobody could answer his questions: "what happens when it's wrong once? And where does our data go?" So the agents stayed off, and the productivity stayed on the table. The Fed has since priced that table: 2.2 hours per employee every week on average, 9+ for the top 27%, 20+ for the power users.
The last page was one company. In April 2026, Stanford published survey data showing the same standoff across the whole market.
of surveyed organizations use AI, and 70% run generative AI in at least one function. Adoption is not the bottleneck.
Scaled deployment of AI agents sits in the single digits of respondents across nearly all business functions. In most functions, a majority report no agent use at all.
frontier models the UK AI Security Institute tested on cyber evaluations tried to cheat; the worst in one run in seven (AISI, July 2026).
name security and risk the primary obstacle to scaling agents, ahead of technical limitations (38%), regulatory uncertainty (38%) and gaps in responsible-AI tooling and control (36%).
"The data does not point in a single direction. It reveals a field that is scaling faster than the systems around it can adapt."
Adoption is measured. The blocker is named. And the budget already exists: at organizations with $30B+ revenue, 41% expected to spend $25M+ operationalizing responsible AI (p. 16).
The agents just got hands: for two years AI could only talk, now it pays, deletes, publishes and signs, and the supervision layer did not ship with it. Three ways companies handle that today. Each one is a cost, not an answer.
Looks safe, compounds against you: a 500-person company leaves $4M to $16M a year on the table by waiting (Fed-measured hours, floor to top quartile).
50 agents acting every two minutes is 1.08M actions a month. Spread over 100 employees, that is 540 approvals per person per working day, one every 53 seconds. The supervision tax eats what the agent was hired to save.
Agents run untrusted, failures go untraced, and the first sign of trouble is the bank statement.
One line of config in front of each MCP server, and every tool behind it is covered. No migration, no keys in the agent, one policy across every lab. One thing, in this order: the gate today, the evidence next, insurance after. We do not build agents.


And the rejection is feedback, not death: "no W-9 on file" goes back to the agent, it returns with the W-9, is held again because a rejected pattern doubles its odds, a person confirms, and the $1 canary goes first.
Benchmarks say what a model can do. The ledger says what it did. You will run brains you didn’t build and can’t audit, so trust comes from watching what they do: every incident lands in the Near-Miss Report as a conduct grade per agent, A to D. Not alignment inside the model, which a distilled copy leaves behind: control during the window, at the point where the action becomes real, safeguards that hold even if the model is wrong, or lying.
The ops agent's first-ever payment call is held before it runs. Deviation is measured from the mandate, not guessed from the prompt.
The same action re-submitted after a human said no: the agent freezes on the spot, and stays frozen until a person thaws it.
Loops, structuring, off-hours activity: tripwires on aggregates and clocks, the patterns a single-action review never sees. A burst of holds freezes the agent by itself.
of companies have delayed AI deployments because data security and governance weren't ready. Not budget. Not buy-in. Data. AvePoint State of AI, 2026
PII becomes vault tokens before the model reads it. Real values return only inside an approved send.
3,200 customer records headed outside fail closed, the same way a $48,200 wire does.
Every field that crossed the boundary, in the hash-chained trail: breach scope in one query.
Policy picks the brain by data class: EU data on EU-hosted models, sensitive corridors self-hosted.
The whole market organizes on one axis: when does the control act relative to the moment the agent’s action becomes real.
Pre-revenue, by design: the first signatures set the price. What exists is a pipeline built from one demo and one question, "and if it's wrong once?"
The zeros are the next gate, not a footnote: the model assumes one shadow week in two converts. Gate 2 is where this column turns into ARR.
Why they say yes: the report is evidence for an audit they already have to pass, and the gate answers the question that stalled their rollout.

TAM, per year. ≈50M managed enterprise agents by 2029 (~5% of IDC's ≈900M) × ~$1,200/yr of governance and evidence spend.
SAM. The reachable wedge: ~5M agents in cloud-first, compliance-bound fleets, US and EU.

Per agent, per month. Never per action: metering invites selective safety, and the ledger needs 100% coverage. Humans ride free; an agent with no action in a month is not billed.
Every AGI needs an AIG, and we are building the control layer every carrier of agent risk will price on. Only the party in the doorway can measure near-misses; everyone else rents the balance sheet and the data, we rent only the paper. The gateway is fully useful at one customer, and the ledger ranks models by consequences, not by votes.
Pattern memory is live per customer; at network scale one near-miss will inoculate every fleet, and actuarial value keeps paying after data effects fade: errors fall, stakes rise, the price of a mistake does not.
Years of immutable history don't migrate. Retention compounds with tenure.
AIUC-1 certifies the agent at a point in time; a policy pays on what happened per action. The ledger is that record. Aligned with the standard, not against it: the mark that matters is on the claim file.
CEO plus a CTO co-founder closing with the round, founding engineers for protocol and risk, two forward-deployed engineers for design partners, and a fractional security lead, hired against the gates: about $1.8M over 24 months, roughly $120k/mo once the full team is in place.

The case we ask you to underwrite is the low one: 138 customers and $7.6M of ARR at month 36 on an $8M seed instead of $12M, lowest cash $0.46M before the seed, and cash never runs out. The base case is $39M. Outcomes: floor, the Datadog of agents · base, the Coalition of the agent economy · ceiling, the AIG of the AGI economy. Acquirers at the floor: Datadog, CrowdStrike, SentinelOne, Palo Alto, Cloudflare, Okta, the carriers; the labs buy the data, not the layer.
Every hard question we have been asked, answered in advance.
Perfect execution of a wrong or ambiguous instruction: "wire the deposit" to the outdated account: is still a disaster with zero agent error in it.
A flawless agent flawlessly executing an attacker's injected instruction is the scariest version. Servers don't make mistakes; we still firewall them.
Perfect reasoning on a forged invoice is still the wrong wire. The world stays wrong even when the model doesn't.
It will happen: a risk engine that catches everything is an oracle, and security's founding axiom is assume breach. This is control, not alignment: safeguards that hold even if the model is misaligned. Anthropic's own threat report concedes the limit: banning an account stopped the tokens, not the surveillance platform already deployed. What changes is everything around the miss:
The action went through the gateway: forensics is one query, not weeks of archaeology.
Blast radius instantly visible; everything in a rollback window comes back; the agent freezes with one policy flip.
The pattern scores higher tomorrow: a rejection doubles its odds, live today. Propagation across workspaces is on the roadmap.
A loss despite reasonable controls is the definition of an insurable event, and the audit trail is the claims file.
Agent losses are "silent AI": falling between cyber, E&O, and crime policies that never contemplated an autonomous actor. Mount (YC S26): cyber/E&O blends at multiples of comparable cyber. The price of not knowing.
$1M aggregate, named perils only. Tight caps are what "we're guessing" looks like in contract form.
Fronting and reinsurance (Mount lists Guy Carpenter, Aon, Zurich). And they bundle outside-in scanners: the tell of a data-starved category.
Markets settled this long ago: you don't ban trade types, you price every decision in real time. Decades of live trading stress-tested the principle. Ripcord applies it to agent actions.
A log-odds scorecard, the FICO convention: +15 points doubles the odds. Calibrated to P(flag), gated by expected loss: P × exposure × (1 − recoverability). A 24-hour flow window catches five payments of $9,640 as one $48,200. Every point is itemized as a reason a human can argue with, and your own rules enter the same math.
Baselines learned per customer with robust statistics (median and MAD, not poisonable means), so abnormal means abnormal for you. Every verdict replays from the context it was made in, so the table never trains on hindsight. Severity calibrated from realized exposure.
Every human verdict is a training label. A network-trained model predicts P(a human would reject), with conformal guarantees on what gets released and extreme-value tails for the 1-in-1,000 loss underwriters price. The risk brain, and the exam every other model trains to pass. Never a competing agent: the referee does not join a team.

Why not AIR, Zenity, Hodor or Speakeasy? AIR and Zenity vet what an agent may load; Hodor and Speakeasy scope which servers and tools it may reach, before the call. We gate what it does with that access and take it back: a vetted server still needs someone to approve the $48,200 wire, and a ledger the auditor accepts. Why not Raindrop? Observability flags the failure afterwards and can neither hold the action nor take it back; its $35M Series A (CRV, Lightspeed, September 2026) prices the category. Why not AIUC? Point-in-time certification and Lloyd's-backed cover that pays after the loss ($40M Series A, Ribbit): the agent still needs a gate the day it acts and the claim still needs the record; we are the carrier partner, not a rival. Why not Harbor? Same thesis, other order: insurance first ($10M seed, Base10, Abstract, 8VC, October 2026), authorization without undo; to underwrite behavior it needs the gate it has not built.

Not forecasts. Six of the ten incidents in our public file, every fact sourced, and the ones with a single source say so.
Behind the six, a base rate: documented AI incidents rose 55% in a year, more than triple the pre-2022 rate. The OECD's separate monitor logged 435 in January 2026 alone, about 14 a day. Both trackers only count what reached the press.
“$48,200 wired to a brand-new vendor.”
RIPCORDHeld until a person owns the yes. A $1 canary proves the rails first. Compensation is the fallback if it ever slips.
“1,240 customer records deleted overnight.”
RIPCORDSnapshot taken before it runs. Rollback is one click from the ledger, inside a window the policy sets.
“6,200 customers emailed: your refund is approved.”
RIPCORDLeaves in batches with a stop verb: halted at email 50, not 6,200. Mass sends above the line wait for a person.
“The launch post fires with last month’s discount.”
RIPCORDA regret window after it fires: pull it from the ledger in two minutes. Escrow to a slot with a re-check at fire time is on the roadmap.
For two years AI could only talk. Now it pays, deletes, publishes and signs, and the supervision layer didn't ship with it. Better models won't close the gap: the arithmetic below is why.
