Fusegate
Budget caps, fallback and kill switches for automations you run yourself
Fusegate is a credential proxy for people who run their own automations in n8n and similar tools: each workflow gets its own budget, a fallback chain of models for rate-limit and outage events, and a kill switch that halts a loop the moment spend deviates from that workflow's baseline.

Test it before you build it
$200 · 4 weeks · 20 prospects
For $200 and 4 weeks, prove that solo n8n operators will route their API keys through a proxy and prepay $100 for per-workflow caps and kill switches.
Riskiest assumption · A solo n8n operator will hand production API keys to a stranger's proxy and pay 2% of governed spend for caps and fallback, instead of relying on provider dashboards, n8n error branches, and hard limits in the OpenAI or Anthropic console.
1Focus group: who and where
A solo automation operator or one-person agency running 5 to 20 n8n workflows on paid OpenAI or Anthropic keys for a small business, who ate at least one surprise API bill over $100 from a looping or retrying workflow in the past year.
where to find 20 · The official n8n Community forum at community.n8n.io (search 'unexpected API cost' and 'infinite loop' threads), the r/n8n subreddit (100k+ members, regular bill-shock posts), the creator listings on the n8n workflow template hub at n8n.io/workflows, and Upwork's n8n automation freelancer listings for operators running client workflows.
2Sell first, build later
A founding-operator slot: by October 5, 2026, your first 10 workflows run on Fusegate keys with a dollar cap each, a fallback model chain for outages, a kill switch on spend deviation, and a weekly report pricing every workflow. I onboard you personally on a call.
the ask · $100 prepaid founding credit, then 2% of governed spend once live; the credit applies against your first fees
a real yes · A real yes is the $100 charged and at least three workflows' keys scheduled for swap on a calendar-booked onboarding call. 'This should exist' and unpaid beta signups 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. Fifteen runaway-spend interviews
$0 · 10 days
Reply to and DM 40 authors of cost-shock threads on community.n8n.io and r/n8n and book 15 twenty-minute calls. Walk through their worst incident in dollars, then show a two-page design of per-workflow caps, fallback chains, and the kill switch, and ask the two hard questions: would you swap your API keys for Fusegate keys, and will you prepay $100 today for the founding cohort. Take the card on the call.
keep going if · 8 of 15 report a runaway incident over $100 in the past year, and 5 of 15 agree on the call to swap keys and prepay
2. Free guardrail template wedge
$50 · 14 days
Build a free 'spend guardrail' n8n template with native nodes (a daily cost check that pauses a workflow past a threshold) on a $50 n8n cloud account and submit it to the n8n template hub with a note that Fusegate does this properly per workflow. This tests the card's stated distribution channel: templates that ship with Fusegate pre-wired.
keep going if · 100+ template downloads in 14 days and 5% of downloaders click through to the Fusegate page
3. Founding operator prepay close
$150 · 18 days
Put up a one-page site with the offer, the October 5, 2026 go-live date, and a card checkout for the $100 founding credit, then push every interviewee who hesitated and every template downloader who clicked through to it. Follow up each prospect exactly twice, seven days apart.
keep going if · 6 of 20 operators asked prepay the $100 founding credit
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.
$100
per prospect, refundable
how · A $100 founding credit taken by card at the end of the interview call through a checkout page. Card checkout fits because the buyer is a solo operator with no purchase-order cycle, and prepaid credit against future 2% fees proves they accept the pricing model itself, not just the tool. set up: Stripe Checkout ↗
what it reserves · A slot in the 10-operator founding cohort, hands-on onboarding of their first 10 workflows on October 5, 2026, and the 2% rate locked for a year
refund · Refunded in full if Fusegate is not governing their workflows by October 31, 2026, or on request any time before onboarding.
target · 6 prepaid credits from 20 conversations within 30 days
Go: build it if
6 or more $100 prepays out of 20 asks, 100+ template downloads, and at least 10 of 15 interviewees willing in principle to proxy their keys: build the proxy.
Kill: stop if
Fewer than 3 prepays out of 20 asks, or 8 or more of 15 interviewees refuse outright to route production keys through a third party: stop, the trust barrier kills the wedge regardless of the pain.

outreach message
Your thread about the workflow loop that burned through your API budget overnight hit home. I'm building Fusegate: swap your API keys for Fusegate keys and each n8n workflow gets its own dollar cap, a fallback model chain for outages, and a kill switch the moment spend deviates from its baseline, plus a weekly report pricing every workflow. I'm picking 10 founding operators running 5-20 workflows. Got 20 minutes this week to walk me through your worst incident?

A dollar cap and kill switch on every n8n workflow $100 founding credit: caps, fallback, and kill switches on your first 10 workflows, then 2% of governed spend Prepay $100, refundable until you are live - founding cohort onboards October 5, 2026
deposit terms
Your $100 reserves one of 10 founding-operator slots and applies in full against your first Fusegate fees. Onboarding starts October 5, 2026, with your first 10 workflows capped and governed on the call. Full refund on request before onboarding, or automatically if you are not live by October 31, 2026.

The concept in full
- What
- Fusegate is a credential proxy for people who run their own automations in n8n and similar tools: each workflow gets its own budget, a fallback chain of models for rate-limit and outage events, and a kill switch that halts a loop the moment spend deviates from that workflow's baseline. A weekly report prices every workflow so the operator knows which automation earns its cost. In the first hour an operator swaps API keys for Fusegate keys in three workflows and sets a dollar cap on each.
- Grounded in (2025-2026 signals)
- n8n raised $180 million in October 2025 at a $2.5 billion valuation on revenue past $40 million growing tenfold in a year. Gartner (June 25, 2025) predicts over 40% of agentic AI projects cancelled by end of 2027, with cost the leading reason. YC's Fall 2026 RFS includes 'A Cloud for Small Software', infrastructure for exactly this operator.
- What it rides
- 'n8n: $180 million at $2.5 billion for self-run automation': the October 2025 round confirmed operators wiring AI steps themselves at scale, and every one of those workflows spends tokens with no per-workflow governor.
- Why now
- n8n's tenfold revenue growth to past $40 million (October 2025 round) means the population of self-run AI workflows is compounding, while Gartner's June 25, 2025 finding that cost kills over 40% of agentic projects makes a per-workflow governor the cheapest insurance an operator can buy.
- Wedge: first customer and entry point
- Solo operators automating a small business with five to twenty n8n workflows; entry is a free tier governing three workflows, then usage pricing at 2% of governed spend, sold through n8n community templates that ship with Fusegate keys pre-wired.
- Closest real companies, as the generator saw them
- None tracked at the workflow-budget layer; Woz governs a coding tool, Prism deploys agents but does not meter them per workflow, and n8n itself orchestrates without enforcing spend.
- Main risk
- n8n builds native per-workflow budgets and fallback, absorbing the governor into the orchestrator.
