How Holafly transformed data management and scaled globally with Weld

Holafly is a leading eSIM provider, connecting travelers with seamless internet access worldwide. Founded to address the challenges of staying connected abroad, Holafly has grown into a global business with operations spanning Southeast Asia, South America, Europe, and beyond.

As Holafly scaled, managing and analyzing data from its rapidly growing customer base and diverse markets became increasingly complex. Marketing and sales teams needed reliable insights to optimize campaigns and uncover emerging markets, while technical teams faced mounting workloads from manual data ingestion processes.

To address these challenges and empower data-driven decision-making, Holafly partnered with Weld. The result? A streamlined data management solution that supports their continued global growth and equips teams with the tools they need to succeed.

Results with Weld

• Reduced time for data ingestion: Manual setup processes that took 2-3 days were reduced to a few clicks, saving approximately 40 hours per month.
• Streamlined carrier data: Consolidated data from multiple providers into a single actionable table.
• Enhanced marketing decisions: Improved campaign performance by identifying high-performing emerging markets.
• Cost and error reduction: Eliminated manual pipelines, reducing development costs and minimizing errors.
• Empowered teams: Non-technical users can independently query and analyze data, freeing up technical resources.

The complexities of scaling data management globally

As Holafly expanded into new markets, its data landscape became increasingly fragmented. Marketing, sales, and operational data were spread across platforms like Shopify, advertisement platforms, and carrier systems. This fragmentation posed significant challenges. Manual data pipelines were a major hurdle.

“Before Weld, we had to rely on GCP services, writing custom Python scripts, and setting up cloud schedulers. It was a time-consuming and error-prone process.”

Without an automated solution, teams spent valuable time managing data ingestion, validating its accuracy, and ensuring its consistency. Fragmented carrier and marketing data further delayed insights critical for decision-making. Global operations spanning multiple time zones added complexity, requiring a scalable solution that facilitated collaboration.

How Weld simplified Holafly’s data processes

Holafly turned to Weld to simplify and centralize its data operations. Weld’s automated data pipelines eliminated the need for custom scripts and manual processes, enabling teams to focus on generating insights rather than managing infrastructure. Weld serves as the backbone of Holafly’s data operations, seamlessly integrating with BigQuery as their data warehouse and Mode for analytics. This setup ensures efficient storage, actionable insights, and streamlined workflows, all powered by Weld’s automation capabilities.

One key application of Weld was connecting carrier data to analyze profitability.

“Our carrier team relies on Weld to consolidate data from multiple telecommunications providers into a single table, providing a clear view of profitability and operational efficiency.”

Another vital use case was optimizing marketing campaigns. By integrating with Shopify and advertisement platforms, Weld allowed Holafly’s marketing team to track campaign performance and optimize ad spend. Emerging markets became a focal point as the team analyzed customer behavior and identified trends such as shorter eSIM usage durations.

“Previously, building a new connector manually would take approximately 2–3 days of development. With Weld, the same process is completed in just a few clicks, drastically reducing the time and resources required.”

Scalability was another transformative benefit. Weld enabled seamless integration with multiple data sources, allowing Holafly to scale operations without prioritizing certain connections based on resource constraints. This ensured that as the company grew, its data processes could scale effortlessly alongside it.

Moreover, Weld reduced costs and risks associated with manual development. By eliminating custom-built connectors, Holafly minimized errors and saved on development costs while ensuring data accuracy and consistency. Finally, Weld’s user-friendly interface empowered non-technical users to engage with data independently. This feature freed up technical resources and allowed all teams to make data-driven decisions efficiently.

“Having all our data centralized allows us to focus on insights and collaboration, rather than worrying about infrastructure or pipeline management.”
