Christina Camacho, CTP | Founder and CEO at Thinifi
​
Christina Camacho, a Certified Treasury Professional (CTP), is a trailblazing entrepreneur with almost two decades of experience in the banking sector. In 2016, Christina became the 18th woman in the history of credit card processing to establish a payment processing company, marking a significant milestone for women in the industry.
​
In 2018, she founded Ivy Lender, a small business lending platform dedicated to supporting underserved small businesses and partnered with 90 payment processing companies and over 60 financial institutions in both Canada and the U.S. to deploy small business loans. Under her leadership, Ivy Lender played a crucial role in the deployment of over $800 million in stimulus funds during the economic challenges of 2020. Remarkably, her platform was the only company that offered a dual applications that enabled businesses to access both Paycheck Protection Program (PPP) and Economic Injury Disaster Loans (EIDL) on a single web app.
​
Despite her professional success, Christina faced significant personal health challenges. The stress of running FinTech firms, raising venture capital, and balancing her personal life led to high cortisol levels, rapid weight gain from insulin resistance, and a diagnosis of PCOS, endometriosis and fibroids. These conditions necessitated blood transfusions, iron infusions, and ultimately, a hysterectomy at the age of 37.
​
Driven by her own health journey and the difficulties in finding quality care, Christina launched Thinifi. Through her own successful journey with Tirzepatide, where she lost 70 pounds in seven months, she is committed to building a platform that is inclusive and offers a multi-tiered approach to health, fitness, and overall wellness.
Christina continues to walk alongside her clients, sharing in their weight loss journey while striving to achieve her personal wellness goals. Her mission with Thinifi is to provide the support and resources necessary for others to succeed in their own health transformations. Christina has been an active member of the Junior League for over 15 years. She served on the State Board of Directors for the Public Affairs Committee, collaborating with state legislators to advocate for crucial issues such as childhood literacy, human trafficking, and food deserts. Additionally, she has held positions on the Executive Board of Directors for multiple non-profits, demonstrating her deep commitment to giving back to her community.
