How LevelUp Leads Drove 500 More Connects Per Month Using Wiza API

As Founder and CEO of LevelUp Leads, John Karasant leads a full-service SDR appointment-setting agency focused on building high-converting outbound campaigns for clients across industries.

But behind the scenes, running a 40-person SDR engine is no small feat. Before adopting Wiza, John’s team wrestled with a familiar set of pain points:

• High costs from other data platforms, including pricey Clay credits
• Inconsistent data accuracy leading to wasted sends and bad deliverability
• Limited access to comprehensive, verified contact data
• Manual enrichment processes creating bottlenecks
• Difficulty maintaining quality across dozens of simultaneous campaigns

These problems didn’t just slow one team down—they rippled across the entire fulfillment operation, touching every SDR responsible for sourcing and validating contacts.

LevelUp Leads needed a faster, more scalable, and more cost-efficient way to fuel its outbound engine without compromising on data quality.

After exploring the market, John came across Wiza through a connection from a previous company.

The pitch was simple—real-time, verified contact data with Clay API integration and predictable pricing.

Wiza delivered on all three. By implementing Wiza’s API, LevelUp Leads gained:

• Unlimited real-time enrichment without hidden fees
• Clay API integration to automatically feed data into workflows
• Verified emails and phone numbers with industry-leading accuracy
• Faster campaign setup times with consistent, scalable sourcing

In short: Wiza became the enrichment engine powering every SDR on the floor.
