Overview
Our client, an AI-driven talent sourcing startup founded by a serial entrepreneur with a proven track record in HR Tech, is revolutionizing how recruiters and founders connect with top talent. The platform’s advanced search tools, ATS integrations, and personalized outreach features streamline the hiring process, enabling users to focus on building their teams and scaling their businesses.
As an early-stage startup, the client aimed to enhance their outreach and engagement features by integrating high-performance contact data solutions while keeping costs lean to ensure sustainable growth.
Highlights
• Identified and recommended two cost-effective, high-accuracy contact data partners.
• Facilitated free API credits and data testing to validate seamless integration.
• Enabled the client to onboard one vendor for phone numbers and another for email addresses to maximize performance and minimize cost.
• Helped launch new Phone Lookup and Email Discovery features, reducing sourcing-to-hire time to just two weeks.
Challenge
The client had a robust 200M US candidate database for sourcing but faced a significant gap: they lacked accurate personal email addresses and phone numbers to power their outreach and engagement features effectively.
As an early-stage startup, the client prioritized maintaining a lean budget, avoiding large commitments until they could demonstrate initial success with smaller investments. They needed reliable data providers that could seamlessly integrate with their existing systems while ensuring verified contact information to reduce bounce rates and improve recruiter engagement.

Solution
To address the client’s challenges, DataVertex leveraged its extensive network of data partners and provided the following support:
Identifying Cost-Effective Contact Data Providers:
• We introduced two contact data partners with competitive pricing and a proven track record for delivering verified email addresses and phone numbers.
• The providers were selected based on their ability to meet the client’s cost-conscious requirements while ensuring high engagement rates.
Data Evaluation and Testing:
• The initial evaluation confirmed that the selected data providers offered the right data points and could seamlessly integrate with the client’s existing candidate database.
• Further testing validated the quality, performance, and reliability of the contact data, ensuring accuracy and strong engagement potential.
Dual Vendor Strategy:
• Based on the testing results, the client onboarded one vendor for phone number lookups and another for email address discovery, ensuring optimal performance across both use cases.
Implementation Support:
• We worked closely with the client and data partners to ensure smooth implementation of the APIs, aligning delivery methods with the client’s technical infrastructure.

Results
• New Features Launched: Within one month of signing the deals with the data partners, the client successfully launched Phone Number Lookup and Email Discovery features, enhancing the platform’s outreach and engagement capabilities.
• Improved Hiring Efficiency: The tool now enables recruiters to make hires within two weeks from sourcing to hiring, significantly reducing time-to-hire.
• Cost-Effective Investment: By starting with smaller investments and leveraging free testing, the client achieved initial success without overextending their budget.
• High Engagement Rates: The verified contact information ensured low bounce rates and improved recruiter engagement with potential candidates.
