An enterprise communications platform for a global workforce
Sigma AI required an enterprise communication platform capable of managing recruitment and workforce communications across multiple countries while supporting GDPR obligations and enterprise security controls.
Arino One designed a dedicated communications platform running on Infobip infrastructure that combines WhatsApp Business Platform, workflow automation, AI-assisted communications and enterprise governance into one operational system.
What Sigma AI needed to solve
Manual recruitment communication
Coordinators handling applicant messaging by hand across email, phone and spreadsheets.
Thousands of applicants
Continuous inbound application volume that no manual process could absorb.
Global workforce
Contributors spread across dozens of countries, languages and time zones.
GDPR obligations
EU data protection obligations applied to every candidate record and message.
Consent management
Verifiable opt-in required before any WhatsApp outreach could take place.
Multiple HR users
A distributed recruitment team needing shared, governed access to one channel.
Recruitment automation
Repetitive lifecycle messaging that had to run without human intervention.
Enterprise reporting
Leadership visibility across volume, response rates and consent state.
One operational system, built on Infobip
Dedicated WhatsApp Business Platform
A single-tenant enterprise sender owned by Sigma AI, not a shared pool.
Infobip Infrastructure
Carrier-grade delivery, throughput and global reach underneath the platform.
Workflow Automation
Event-driven journeys triggered by candidate status changes.
AI Assisted Recruitment
AI drafting and triage for candidate questions and routine responses.
WhatsApp Templates
Meta-approved, localised templates for every lifecycle message.
Multi-user HR Teams
20+ recruiters working one shared inbox with assignment and handover.
Consent Management
An append-only consent ledger recording every grant and withdrawal.
One Tap Meta Opt-In
Native Meta opt-in flow capturing verified consent at application.
Automated Opt-Out
Keyword and button opt-out processed instantly and enforced platform-wide.
GDPR Dashboard
Live compliance view of consent state, requests and retention.
Data Erasure Workflow
Right-to-be-forgotten requests executed with a signed completion receipt.
Candidate Journey Automation
End-to-end sequencing from application through to onboarding.
Analytics
Delivery, engagement and funnel reporting by campaign and market.
Role Based Access
Granular permissions separating recruiters, admins and compliance.
Audit Logs
Immutable record of every user action and data access event.
Compliance engineered in from day one
Compliance was not retrofitted after launch. Consent capture, validation, retention and erasure were designed into the platform architecture before the first message was sent — so every candidate conversation is defensible, every action is logged, and every data subject request can be fulfilled within statutory deadlines.

Built on Lovable, provisioned and managed by Arino One
Arino Core is built on Lovable and runs on Infobip's enterprise messaging infrastructure. Sigma AI does not assemble, host or maintain any part of the stack: Arino One provisions each dedicated instance, configures the WhatsApp Business Platform senders with Infobip, and operates the platform as a managed service.
- Built on Lovable — Arino Core is developed and deployed on Lovable, with managed builds, hosting and release control.
- Provisioned by Arino One — Every instance, sender and integration is provisioned by our team — never self-assembled by the customer.
- Enterprise Infobip infrastructure — Messaging runs on Infobip's carrier-grade platform with official WhatsApp Business Platform connectivity.
- Dedicated tenancy — Data, senders and configuration are isolated per customer instance rather than pooled.
- Encryption in transit and at rest — All traffic and stored data are encrypted using industry-standard protocols.
- Role-based access control — Least-privilege permissions separate recruiters, administrators and compliance users.
- Audit logging — Every user action and data access event is recorded on an immutable trail.
- Managed monitoring and updates — Arino One handles patching, monitoring, incident response and platform upgrades.
This page is maintained by Arino One and describes the controls enabled for this deployment. It is not an independent audit, certification or security attestation. Responsibilities are shared: Lovable and Infobip provide the underlying platform and messaging infrastructure, Arino One provisions and operates Arino Core, and the customer owns its own data-protection policies and lawful basis for contacting individuals.
The automated candidate journey
Application
A candidate applies and submits verified WhatsApp opt-in via the Meta one-tap flow.
WhatsApp confirmation
An instant templated confirmation acknowledges the application and sets expectations.
Interview invitation
Scheduling invitations are dispatched automatically as candidates advance.
Assessment reminder
Timed reminders reduce drop-off before assessments expire.
Candidate support
AI-assisted replies handle routine questions; complex cases route to a recruiter.
Status updates
Progression, outcome and onboarding updates are pushed at every stage change.
HR notifications
Internal alerts notify the right recruiter the moment action is required.
Outcomes at enterprise scale
What the platform runs on
From a messaging channel to operational infrastructure
Before Arino One, WhatsApp was simply another place where conversations happened. Today it is the operational backbone of Sigma AI's global HR function: a governed, auditable system of record where recruitment communication is provisioned, automated, measured and retired under policy.
Recruiters no longer chase candidates individually — the platform sequences every touchpoint, escalates only what needs a human, and records consent and activity as it goes. Compliance teams no longer reconstruct evidence after the fact; the consent ledger, audit trail and erasure workflow produce it continuously. Leadership sees one reporting surface across every market.
The result is enterprise conversational infrastructure: dedicated, governed and scalable, capable of supporting a workforce of more than 25,000 contributors without adding headcount to keep pace with growth.
