Workflow Automation — BPA, iPaaS & RPA
Entry signal — what decides who wins here
One thing must be trueEntry turns on a single condition that can be named and tested before much is spent. Clear it and this becomes an execution question; fail it and no amount of operating skill helps.
Displace an incumbent the screen found well defended — payments attached to the workflow, data that does not leave, a contract that renews itself. Share here means giving a buyer a reason to break something that currently works, which is a higher bar than being better.
Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.
This is not a probability of success, and it is not a verdict on you. No survival probability is published per market, and inventing one would be worse than saying so. What the bar reads is how much of the outcome sits inside an operator's control: green means the hurdles are ones a better operator clears, red means the binding constraint is capital, an asset or a permission rather than execution. Someone arriving with an advantage this screen did not assume can win a market shown in red.

The binding constraint — incumbent vulnerability
Four acronyms, one buyer budget, and every segment already has a funded leader plus a platform vendor giving it away in a bundle. The market sorts itself by what gets automated. iPaaS (integration platform as a service) moves data between systems and is bought by IT: Workato, Boomi, MuleSoft (Salesforce) and Tray.ai. RPA (robotic process automation) drives the screens of systems that have no API, using software bots: UiPath, Automation Anywhere, and the desktop-flow side of Microsoft Power Automate. BPA (business process automation) is the form-and-approval layer where people stay in the loop — purchase approvals, onboarding, requests: Pipefy, Kissflow, Nintex and ServiceNow's workflow products. No-code and AI-agent workflow builders are the trigger-and-action tools a team adopts without IT: Zapier, Make (Celonis), n8n and Activepieces. The segments are converging, because every vendor now sells "agentic automation" and reaches into its neighbours' ground. The size of the leaders is the argument against entry. UiPath alone reported $1.611B of fiscal 2026 revenue and $1.853B of ARR [A]. ServiceNow, whose platform is workflow at its core, reported $13.278B of 2025 revenue [A]. Microsoft sells Power Automate Premium at $15 per user a month [C, vendor price list], inside the Power Platform its Microsoft 365 customers already run. Zapier reached roughly a $5B secondary valuation in 2021 on about $1.2M of venture money [C]. Capital is still pouring into the newest tier: n8n raised $180M at a $2.5B valuation in October 2025 [B], after reporting tenfold revenue growth in a year [C, vendor]. The free tier is real. n8n's source is public under a fair-code licence that allows internal business use, and Node-RED, Apache Airflow, Activepieces and Windmill are open source. A new paid builder competes on price with zero. How this differs from the neighbouring records. Project Management Software tracks tasks that people do; this record covers software that does the work between systems. AI Agent Infrastructure & Evaluation sells tracing and testing to engineers who build agents; the builders here sell the finished workflow to the business. MSP Remote Monitoring & Service Automation is automation sold to managed IT providers for their clients' endpoints, a different buyer. Incumbent vulnerability decides it: no segment has a leader that is weak, and the one fast-growing challenger, n8n, is already funded to the billions.

The incumbent
Who owns this market and who is coming for it. Fields a screen never reached say so rather than guessing.
Market size, derived
Built from the competitor set upward rather than quoted from a forecast. Published TAMs in these categories are frequently reverse-engineered from each other, so any published figure is checked against the vendor arithmetic rather than trusted on its own.
Disclosed revenue from 2 of 14 named vendors. The market is at least this large.
No vendor has both a disclosed revenue and a published share.
Only a revenue floor is known — the true market is larger by whatever the undisclosed vendors earn.

Open source · 5 projects — the price floor
Source-available rather than OSI open source: internal business and personal use are free, reselling it as a service is not. The fastest-growing builder in the category
Flow-based, event-driven low-code tool, an OpenJS Foundation project; strongest in IoT and industrial integration
Workflow orchestration for data pipelines, written in Python; an engineer's tool, not a business-user builder
Y Combinator S22; self-hostable Zapier alternative
Code-first: turns Python, TypeScript, Go, Bash and SQL scripts into workflows and internal apps
The open tier is real, and in this category it is the challenger rather than a hobby. A workflow engine is code that calls APIs on a schedule or a trigger, which a community can build and a technical team can host. n8n turned that into a $2.5B company by publishing its source under a licence that lets any business run it internally for free.
Evidence
Evidence. Category market size UNVERIFIED — no iPaaS, RPA or BPA total was sourced, and none of the private leaders publishes revenue. Two revenue floors were opened: UiPath's fiscal 2026 results (8-K exhibit 99.1, 2026-03-11: revenue $1.611B, ARR $1.853B) [A] and ServiceNow's full-year 2025 results (investor release, 2026-01-28: revenue $13.278B, subscription $12.883B) [A]. ServiceNow's figure is the whole company and is not a workflow-automation figure. Funding rounds opened: n8n's Series C in Highland Europe's release (2025-10-09) [B]; Workato's Series E in Silicon Canals [B] (BusinessWire returned 403); Automation Anywhere's Series B in Crunchbase News [B]; Tray.io's Series C in TechCrunch (2019-11-26) [B]; Pipefy's Series C in LAVCA (2021-10-26) [B]; Celonis–Integromat in TechCrunch (2020-10-14) [B]; Dell–Boomi in TechCrunch (2021-05-03) [B]; TPG–Nintex in Lincoln International's deal note [B]. Zapier's seed round and 2021 secondary are from Wikipedia [C]. It gives $1.2M where search snippets give $1.3M, and the figure is recorded as about $1.2M. Sacra's Zapier ARR estimates were seen in search results and NOT used. Power Automate prices were opened on Microsoft's pricing page (2026-10-09) [C, vendor]. That page does not say what Microsoft 365 includes, so the bundling claim is about the Power Platform being sold to the same customers, not about free entitlements. Licences were read from the repositories: n8n LICENSE.md (Sustainable Use License plus n8n Enterprise License), Windmill (AGPL with Apache-2.0 portions and proprietary enterprise features) and Activepieces (MIT outside the ee directories). Node-RED and Airflow licences are as published by their foundations and were not re-opened. Not sourced: MuleSoft's revenue inside Salesforce, Kissflow's funding, and the funding of Activepieces and Windmill, which appears only in aggregators. Verify before acting.
