Goal
Design and build Holafly Business Center, a corporate connectivity management platform, from scratch, with Iberia, Volvo, and BBVA as the first enterprise clients
Problem
There was no existing product to iterate from. The buyer (IT manager) is not the user (the traveling employee). This was a zero-to-one design challenge with a fundamentally different product logic from B2C.
Key Insights
The admin is not the employee, every design decision had to be made from the IT manager's perspective. The employee's eSIM installation experience is handled by the Holafly consumer app, not by HBC.
Bulk assignment was the primary workflow, individual assignment is the exception at enterprise scale. The UI had to lead with bulk (Excel upload) and make individual assignment a secondary option.
Centralized billing was table stakes, IT managers couldn't expense 50 individual receipts. Single invoice view across all purchases was a hard requirement.
Process
Wireframes
Designed the Dashboard as the primary surface: full eSIM inventory overview with state-based filtering, inline status chips, and contextual action buttons per row. Parallel design of the plan architecture (Always On, Unlimited, Enterprise) with clear tier trade-off visibility.
User Flows
Three primary admin workflows: bulk assignment (Excel upload → auto-notification to employees), individual assignment (manual entry), and subscription management (cancel, reassign, reactivate per employee). Each workflow resolved at the dashboard level, no separate management screens required.
Iterations
Naming workshop was a prerequisite, couldn't design state-based UI until the state names were locked. The three-state model (Active / Pending / Unassigned) was finalized before any UI was built, ensuring consistency across the product, the API documentation, and client-facing communications.
Process / Wireframes
Solution
A dashboard-first platform: full eSIM inventory with Active / Pending / Unassigned status chips, contextual action buttons per row, bulk assignment via Excel upload, and centralized invoice view. Plan architecture (Always On, Unlimited, Enterprise) designed to support decision-making without requiring a sales call for most choices.
Final UI / Solution
Full eSIM inventory dashboard with inline status chips and contextual actions
Excel-based bulk assignment, employees receive install instructions via email and WhatsApp automatically
Per-employee subscription management
cancel, reassign, reactivate from dashboard
Centralized billing
single invoice view across all purchases and entities
Outcomes
from zero
Enterprise Clients

Destinations Covered
Holafly Business Center launched and onboarded its first enterprise clients, Iberia, Volvo, and BBVA, within the initial release cycle.
Learnings
What worked
The naming workshop before any UI design was one of the highest-leverage decisions of the project, locking state terminology upfront prevented inconsistency across the product, the API, and client communications.
Excel-based bulk assignment required zero onboarding for IT managers, they already had their employee data in spreadsheets. The upload-to-notify flow handled everything from there.
What I'd improve
In-platform analytics showing which employees are actively using their eSIMs vs. which have pending plans, IT managers want to see utilization, not just assignment status
Role-based permissions within the platform, larger organizations need to delegate assignment to department admins without giving full billing access
