Holafly Tech Stack

eSIM and mobile data plans for international travelers

Telecommunications Dublin, County Dublin 501–1,000 employees Founded 2017 Privately Held

Holafly sells prepaid mobile data plans to travelers, delivered via eSIM, with a founder-led origin story (born from personal travel frustration in 2017). The tech stack is analytics-heavy—Looker, Tableau, Power BI, BigQuery—paired with marketing automation (Klaviyo, HubSpot) and performance-ad spend (Google Ads, LinkedIn Ads, Microsoft Advertising), signaling a growth-stage company optimizing for customer acquisition and unit economics. Hiring velocity is accelerating across marketing (16 roles), support (9), and ops (8), while engineering (7) and data (5) remain lean—typical of a commerce-first org scaling customer-facing functions ahead of platform buildout.
