iPaaS needs an API on both ends. Your system of record doesn’t have one.
Trigger-action platforms are great for wiring modern SaaS together. But Acturis and most legacy broker systems either have no usable API or gate it behind a partner programme, so automation stops exactly where the real work is: the last mile.
iPaaS does connector plumbing between APIs; North Stack does the judgement and the last mile. Zapier, Make and Workato require an API on both sides of every step. The exact task that matters, updating the policy record in Acturis or filing the email against the client, is where iPaaS stops, because that API either doesn’t exist or is partner-gated. iPaaS also can’t read an ambiguous broker inbox and decide which of seven workflows applies, and its run logs are operational telemetry, not a tamper-evident ledger of cited decisions and human approvals. North Stack drives the UI a handler uses, with no API required, reasons over the inbox, and lands every step on a hash-chained ledger.
Connector plumbing vs judgement plus the last mile.
| Capability | North Stack | iPaaS (Zapier · Make · Workato) |
|---|---|---|
| Works with no-API legacy systems | Yes: drives the Acturis UI a handler uses | No: needs an API on both ends |
| Reads & triages an unstructured inbox | Yes: classifies raw email to a workflow | No: trigger-action on structured events |
| Adds judgement, not just plumbing | Yes: reasons which of 7 workflows applies | No: moves data between apps |
| Compliance-grade audit ledger | Hash-chained, cited decisions | Operational run-logs only |
| Human approval gates on writes | Native hard gates | Not compliance-grade |
| Breadth of modern-SaaS connectors | Not the point: we do the last mile | Wins: thousands of connectors |
| Cost for simple SaaS-to-SaaS | Overkill for that | Wins: cheap and fast |
| Setup speed for API-available apps | Comparable, but that’s not our job | Wins: minutes for wired SaaS |
The API dependency problem
iPaaS is built on the assumption that both sides speak API. Acturis has a two-way API, but it’s partner-gated and scoped, not something you can point a Zap at to update a policy record. Most legacy broker systems of record are worse: no suitable API at all. So the connector chain reaches right up to the moment of real work and then stalls. North Stack doesn’t need the API. It operates the same screens your handler does, under supervised, role-scoped access, so it reaches the last mile iPaaS can’t.
Connector plumbing vs judgement + triage
iPaaS does deterministic plumbing: when X happens in app A, do Y in app B. It can’t read a free-text inbox and decide that this email is a mid-term adjustment, thatone is a claims FNOL acknowledgement, and this third one is too ambiguous and should go to a person. That triage, the judgement, is the part that clears the backlog, and it’s exactly what North Stack adds on top of driving the system of record.
Run-logs vs a compliance ledger
A Zapier or Workato run history is operational telemetry: useful for debugging, useless in a thematic review. It’s not tamper-evident, not tied to a versioned knowledge source, and not a record of why a decision was made or that a human approved it. North Stack’s ledger is hash-chained, cites the rule behind each decision, and captures every approval gate. That makes it an FCA-ready file, not a run log.
When to choose Zapier, Make or Workato instead.
If both systems have good APIs and the task is straightforward data-passing between modern SaaS apps, with no compliance burden, no audit trail to defend and no messy inbox to reason over, iPaaS is cheaper and faster, and we’ll say so plainly. Zapier’s thousands of connectors and minutes-to-wire setup are excellent for that. North Stack is for the work that lives outside the API surface: the legacy system of record, the ambiguous inbox, and the regulator who wants the audit trail.
