“We deliver world-class customer service while generating and delivering leads—when and how our clients need them.”

OnCore Leads, a woman-owned enterprise founded by seasoned entrepreneur Carolyn Oliveira, is redefining how small businesses access high-quality leads. With a background in operating multiple successful ventures, Carolyn recognized a widespread need among small business owners for a smarter, risk-free approach to advertising. Fueled by this insight and a passion for supporting business growth, she assembled a global team of advertising and technology experts to launch OnCore Leads—a performance-based lead generation company committed to transparency, results, and client success.

Recently, we had the opportunity to speak with Carolyn Oliveira, CEO of OnCore Leads, to learn more about the company’s growth, innovation, and client-centered mission.

Evolving Landscape of Lead Generation: Post-Pandemic Shifts

“Undeniably, the COVID-19 pandemic disrupted nearly every sector,” Carolyn shares. “Small businesses, in particular, faced challenges such as changing customer behavior, cash flow constraints, and staffing shortages. But with those challenges came a heightened urgency: more businesses needed quality leads than ever before.”

This urgency has fueled increased demand for OnCore Leads’ services, positioning the company as a trusted partner for businesses seeking new customers and revenue opportunities in an increasingly competitive environment.

The Spark Behind OnCore Leads

Carolyn founded OnCore Leads with one goal in mind: to eliminate the risk traditionally associated with lead generation. “Too often, businesses pour money into advertising campaigns that yield little or no results,” she explains. “We flipped the script—our clients only pay when we deliver leads. It’s that simple.”

The company’s “pay-for-performance” model allows clients to order the exact number of leads they want, delivered on their timeline. This approach has eliminated guesswork, reduced wasteful spending, and instilled confidence in OnCore’s ability to generate real results.

About OnCore Leads

Today, OnCore Leads is recognized as one of the nation’s leading lead generation firms. The company proudly boasts five-star client reviews, a flawless customer service record, and an unwavering commitment to delivering qualified leads on time, every time.

“Whether our clients are attorneys, home service providers, or other professionals, they trust us to deliver results. And we never take that trust lightly,” says Carolyn.

A Journey from One Service to a Nationwide Network

OnCore Leads began as a single-service firm, generating leads for tax attorneys through one television ad. The demand quickly expanded, with clients requesting leads in adjacent legal fields such as bankruptcy, personal injury, criminal defense, employment law, and more.

Building on that momentum, the company expanded into the home services sector, where it now supplies leads in categories like roofing, solar energy, plumbing, painting, and window repair. With each expansion, OnCore refined its lead generation strategies to ensure consistent quality and performance across industries.

Understanding the Client: A Core Competency

As small business owners become more digitally savvy, their expectations for advertising performance have evolved. “Our clients want smarter, data-driven strategies,” Carolyn notes. “They’re more open to testing new methods and leveraging emerging technologies to stay ahead of the curve.”

OnCore Leads stays responsive to these changing needs, continuously adapting its processes and platforms to meet rising standards and performance expectations.

Challenges and Resilience: Competing with Confidence

Rather than viewing competition as a threat, OnCore Leads sees it as an opportunity for growth and refinement. “We monitor the broader advertising landscape and adopt best practices that enhance our ability to deliver,” Carolyn shares. “Most importantly, we assume the financial risk in every campaign—our clients never pay unless we perform.”

By aligning their success with that of their clients, OnCore Leads offers a refreshing level of accountability in an industry often marred by uncertainty.

Flexible Solutions for Businesses of All Sizes

OnCore Leads understands that every business has unique financial constraints. Whether working with Fortune 500 companies or sole proprietors, the company delivers the same high-quality service and results.

“Our pricing model is flexible, and our systems are scalable,” Carolyn emphasizes. “We’ve streamlined our processes so that every business—regardless of size or budget—can benefit from our services.”

Adapting During the Pandemic: Staying Agile and Client-Focused

The onset of COVID-19 introduced significant disruption, but OnCore Leads met the moment with agility. “Some of our clients had to pause operations due to local mandates, while others needed more leads than ever,” says Carolyn. “We adapted quickly—scaling back or ramping up based on individual client needs.”

This responsiveness underscored OnCore Leads’ commitment to being more than just a vendor—they’re a true partner in every client’s growth journey.

Client Testimonials: Trust Earned Through Consistency

Client feedback continues to fuel the team’s drive for excellence. A few standout testimonials include:

“I’ve worked with many lead vendors and have often been disappointed. But John at OnCore Leads always delivers—honest, reliable, and results-driven. It’s a breath of fresh air.”

“We’ve tried several agencies for auto accident leads. OnCore Leads has been the best—timely communication, excellent support, and a 3:1 ROI. Highly recommended.”

Such feedback reflects the company’s foundational values: integrity, transparency, and performance.

What Sets OnCore Leads Apart

Named one of the “20 Best Companies to Watch in 2021” and recognized among California’s fastest-growing businesses, OnCore Leads attributes its success to a simple but powerful philosophy: deliver what you promise.

“Our growth is rooted in our ability to generate high-converting leads and offer exceptional service,” Carolyn says. “We’re not just about growth—we’re about sustainable, customer-centered success.”

A Call to Small Businesses: There Is a Better Way

OnCore Leads invites small business owners to rethink their advertising strategy. “If you’re tired of throwing money at campaigns with little to no return, let’s talk,” Carolyn urges. “We’re here to educate, empower, and equip you with a smarter way to grow.”
