As answered by people managing HackerRank and Fetchify.
Fetchify's answer:
Fetchify combines powerful, developer-friendly APIs with trusted, high-quality address and data sources such as Royal Mail PAF®, Multiple Residence, and Not Yet Built datasets to deliver unmatched accuracy. Unlike many validation tools, Fetchify provides granular rooftop-level geocoding, flexible integrations, and transparent pricing — all through a single, reliable SaaS platform that scales effortlessly across ecommerce, CRM, and enterprise systems.
Fetchify's answer:
Fetchify offers a balance of accuracy, speed, and simplicity rarely matched in the data validation market. Our technology focuses on preventing bad data at entry rather than correcting it later, helping businesses cut failed deliveries, boost checkout conversion, and improve customer experience. With global coverage, robust uptime, UK-based support, and flexible APIs that fit effortlessly into existing workflows, and a knowledgable, accessible support team, Fetchify is the trusted alternative to providers like Loqate, Melissa, and Smarty.
Fetchify's answer:
Fetchify is designed for businesses and developers who rely on accurate customer data — from ecommerce and retail to logistics, finance, and marketing but the Fetchify product range is built for any SaaS platform to be lightweight, easy to implement and cost effective to use. Typical users include SaaS developers, data managers, digital marketers, and IT teams looking to integrate address lookup, email, phone, and bank validation directly into forms, CRMs, or websites to improve data quality and reduce operational friction.
Fetchify's answer:
Originally founded as Crafty Clicks in 2008, the business was acquired by software investment group ClearCourse in 2019. Since then, rebranding as Fetchify and investing in our people as well as our products, we have evolved from a simple UK postcode lookup service into a comprehensive SaaS data validation platform serving thousands of global businesses. Over the years, we’ve expanded our product range, added international datasets, and continue our mission to make customer data cleaner, faster, and smarter for every business.
Fetchify's answer:
Fetchify is built on a modern, scalable cloud infrastructure using AWS and proprietary algorithms for high-speed query performance, and robust RESTful APIs for integration. Our services leverage multiple data sources including Royal Mail PAF®, Ordnance Survey, USPS, and other global address providers. Continuous monitoring, automated scaling, and distributed clusters ensure reliability, speed, and resilience across all Fetchify validation products.
