Fusion keeps inboxes, CRMs, ERPs and custom tools aligned in real time — with bi-directional sync, duplicate detection and audit history built in.
Built for the inbox your CRM forgot.
The four things every operations team asks for on day one — shipped.
Mail, calendar & contacts — both ways
Every reply, every meeting, every contact — synced in every direction between your mailbox and your ERP or CRM.
Duplicate detection built in
Fusion fingerprints every contact, deal and thread on the way through. No more three Maria Lindbergs in your CRM.
Sub-second sync
Real-time push the moment a thread lands or a record changes. No polling, no cron jobs, no 6 AM stand-ups.
Encrypted end-to-end
AES-256 at rest, TLS 1.3 in transit, customer-managed keys on Enterprise. Your mail stays yours.
Single source of truth.
Mail, calendar and contacts — mirrored both directions between your mailbox and your CRM. Every reply, every meeting, every contact update, with duplicate detection on the way through.
Works with the systems you already run on.
Native connectors for AVIOR.CRM and the rest of your ERP/CRM stack. If yours speaks HTTP, Fusion can sync it.
Don't see yours? We'll build the connector.
Why ops teams love Fusion.
“We replaced a three-person email triage team with Fusion. Every reply lands on the right deal before anyone reads it.”
“The bi-directional sync is what sold us. Status changes in Dynamics show up in customer threads automatically — no copy-paste.”
“We had 40+ Power Automate flows duct-taping inbox to ERP. Fusion replaced all of them with one connector — and it's faster than any of them ever were.”
“Audit alone justified the price. Every customer conversation now lives next to its order, with full history one click away.”
“Quotes go out, threads stay attached, reps never lose context. Six hours a week back per rep — easy.”
“Onboarded in two days. Not 'launched in two weeks' — actually working in two days. We'd been told that was impossible.”

Built by refineIT.
Fusion is built by refineIT — a 42-person crew of engineers, AI specialists and IT-security folks based in Recklinghausen, Germany. Founded in 2019 with one mission: bring enterprise-grade automation to the Mittelstand, without the enterprise complexity.
We integrate AI and automation so the impact lands on day one — not on sprint 47. Sister company zubIT handles the IT-security and infrastructure side as a Microsoft Solutions Partner, so the stack is covered end-to-end.

What does "bi-directional" actually mean?
Mail flows mailbox → ERP (every reply lands on the right record) and ERP → mailbox (status changes, comments, and updates appear inside the email thread). One conversation, both surfaces, always in sync.
Which systems are supported on day one?
Native connectors for AVIOR.CRM, Microsoft Dynamics 365, NetSuite, Odoo, Sage Intacct, Salesforce, HubSpot, Pipedrive, Xero, and QuickBooks. Anything else, our generic REST/GraphQL bridge covers in a few hours.
Does Fusion store my emails?
Only what you tell it to. By default we store thread metadata and the parsed record links — not the message bodies. You can opt in to full archive on any tier.
Is it GDPR compliant?
Yes. EU data residency on all paid plans, DPA signed before any data flows, and right-to-erasure executes in under 24 hours. SOC 2 Type II report available under NDA.
Can I self-host?
On Enterprise, yes. We ship a Helm chart and a single-binary option for air-gapped environments. Same connectors, your infrastructure.
How fast is the actual sync?
Median 800ms from inbox to ERP record. p99 under 3 seconds. No polling — every mailbox is held open over IMAP IDLE or Microsoft Graph change notifications.
