About
Performance marketing, both sides of the table.
Most consultants in this space only know one side of the table. That's why publishers get stuck with low-quality offers and advertisers burn budget on junk traffic. I'm Liam Liu, founder of nonzero—I've spent a decade on both sides, and I know where the gaps are and how to close them.
Background
I led enterprise sales at Ringba, the industry's leading call tracking and analytics platform, where I focused on acquiring enterprise advertisers to the platform. This role put me at the center of the pay-per-call ecosystem—connecting lead generators with enterprise advertisers, building partnerships, and seeing firsthand what separates high-performing campaigns from the rest.
That experience gave our team deep insight into how both sides of the marketplace operate. We understand what publishers need to scale profitably, and we understand what advertisers need to acquire customers efficiently. Most people in this space only know one side. We know both.
We've also built a deep network across the industry—attending dozens of conferences like Affiliate Summit West and LeadsCon, as well as vertical-specific events across legal, insurance, home services, and finance. These relationships give us access to quality partners that most people simply don't have.

Case Study
From Zero to $1M+/Month in Under a Year
A paid search media buyer came to us with deep Google Ads expertise but zero experience in pay-per-call. They knew the model could work for them—they just didn't know where to start.
We built out their call tracking infrastructure from scratch, integrated it with Google Ads and their CRM, and connected them with pay-per-call networks to start testing traffic. After iterating on lead quality and optimizing their campaigns, we introduced them to one of the largest pest control companies in the US.
Today, they're working with 6+ direct pest control advertisers and generating over $1M per month in revenue—all within their first year in the space.

Areas of Expertise
Our work sits at the intersection of technology, partnerships, and performance marketing:
How We Work
We're a small, focused team—which means you get senior-level attention on every engagement. Whether we're setting up call tracking infrastructure, building out publisher-advertiser partnerships, or managing paid search campaigns, we stay close to the work. You'll always have direct access to people who've been in the trenches, not layers of account managers.
We also believe in transparency. Performance marketing can be a black box, but it doesn't have to be. We work with clients who want to understand their numbers, their systems, and their growth levers—not just outsource and hope for the best.
Let's Work Together
Whether you're looking to scale your call generation, find quality lead partners, or build out your paid search operation—we'd love to talk.
