Onboarding flows
Customer onboarding software you compose yourself
Every business onboards differently, so the flow builder does not prescribe one. You compose your onboarding from 15 building blocks, identity, screening, account and contact checks, set the rules per step, and publish. Consumers get a branded wizard; your systems get per-step results over API and webhooks.

15building blocks, one flow
What is the flow builder?
The flow builder is the dashboard where you assemble an onboarding: pick the checks, order them, and define what a fail means per step. ID document scan, bank identification, IBAN name check, PEP and sanctions screening, address, email and phone checks, plus background actions like webhooks and field transforms.
Publish a flow and you get a wizard URL to send consumers to, or you start onboardings through the REST API. Every step reports its own result, so your acceptance process sees exactly what passed, what failed and why.
From idea to live flow
Three steps, and versioning keeps every change auditable.
1. Compose
Drag the building blocks into order and configure the rules per step in the dashboard.
2. Test in sandbox
Run the flow end to end in the sandbox environment before anything goes live.
3. Publish and integrate
Send consumers to the wizard URL or start onboardings over the API. Results arrive per step via webhooks.
What is in the box: the building blocks by category
Fifteen verification blocks plus background actions, with the dashboard, analytics, team management and branding around them.
The catalogue keeps growing: new blocks and EU Digital Identity Wallet support are on the roadmap. Each block has its own deep-dive page, linked below.
GDPR and compliance
Built for lawful consumer checks
Consumer checks touch personal data, so privacy is part of the design. The consumer walks through the check themselves and sees what is being asked. Each step retrieves only what that check needs, from official sources, and every result is recorded.
Official sources and registers, no scraped profiles
Data minimisation: each check reads only the fields it needs
Every result recorded, ready for regulators and audits

Frequently asked questions
Question not listed? Request a demo
Do I need developers to build a flow?
No. Flows are composed in the dashboard. Developers come in when you integrate the results into your own systems over the API and webhooks, and even that is a thin REST integration.
Can consumers stay on my domain?
The wizard runs hosted in your branding, and you can embed the onboarding in your own site. Results always land in your systems.
Which checks can I include?
ID document scan with liveness, bank identification, IBAN name check, PEP and sanctions screening, address and person validation, insolvency and deceased register checks, email and phone verification, duplicate detection and custom forms.
When can I start?
Today, on quote: request a demo, build a first flow with us and tell us your volume. You receive a tailored quote and after approval your production key.
