Our Story

For press inquiries email Co-Founder Pavan Katepalli at Pavan.Katepalli@INRTracker.com.

Veronica and Pavan aren't just a young couple. They’re the Co-Founders of INRTracker.com.

It all began in early 2012 when Veronica Coulombe, a 20 something front end developer got a blood clot in her leg (Deep Vein Thrombosis - DVT) and also in her lung (Pulmonary Embolism – PE).

Although 1/6 people who get a DVT/PE die, Veronica survived.

To dissolve the clots and prevent future clots, her doctor prescribed her Warfarin.

Veronica later met Pavan Katepalli at her day job. Eventually their work blossomed into a relationship.

While on Warfarin, Veronica had to constantly watch what she ate (especially Vitamin K) and had to get her blood tested weekly (an INR Test) to make sure that her Warfarin dosage was affective. Veronica had to keep everything she did consistent - especially her diet.

If she faltered in diet, her Warfarin could either be further induced or inhibited and she could suffer from internal bleeding or from blood clots.

To make matters worse, food labels don't include Vitamin K, and virtually every drug interacts with Warfarin so she was left feeling overwhelmed.

The stress on Veronica was enormous. As her boyfriend, Pavan felt her pain.

So Pavan embarked on a journey to learn to code. He built a prototype application to let Veronica log her data quickly and easily, and generate reports for her doctor.

Veronica was able to plan her meals out using the application and was able to better understand the Vitamin K and other factors that were affecting her.

Veronica as a front-end developer herself saw the potential in the application, so she helped bring the application to the web.

Fast forward a bit, and INRTracker has raised funding from Houston based Biotech Company, ReliantHeart Inc. ReliantHeart is led by Serial Entrepreneur Rodger Ford.

INRTracker is also integrated with ReliantHeart's HeartAssist5®, a LVAD (Left Ventricular Assist Device). A LVAD is an electromechanical circulatory device that is used to partially or completely replace the function of a failing heart.


INRTracker got its name from the blood test that patients on Warfarin have to take to see if their dosage is correct - called an INR Test.

The K in our logo stands out because it stands for Vitamin K. Vitamin K directly correlates with the amount of Warfarin a patient needs to take. INRTracker lets patients easily track their Vitamin K.

During his tenure as CEO of SynCardia, Mr. Ford guided and directed the development of two new driver systems for powering the Total Artificial Heart. He guided the raise of capital that funded the development and launch of the Freedom portable driver, the world's first wearable power supply for the Total Artificial Heart.

Under his leadership, SynCardia installed modern and effective business systems, such as MasterControl, quality management system software that was also later selected by the FDA. In addition, he recruited an experienced management team that transformed SynCardia from a "science project" into a celebrated bioscience company.


“INRTracker has been a great way for me to get my INR levels in a healthy range. It allows me to calculate my average Vitamin K intake for the week allowing me to enjoy small salads and some green food again! I am excited about the new dashboard, which will provide me additional ways to track my medications, blood pressure ranges and other helpful information for my doctor. Through the INR Tracker I have been able to pinpoint fluctuations in my INR. Instead of testing every week or every 2 weeks I am now able to test once a month and in the future will be able to test every 3 months!”
— Shauna Christine

Each year in the US 300,000 to 600,000 people experience dangerous blood clots. They experience a blood clot in the leg (Deep Vein Thrombosis - DVT) and/or a blood clot in the lung (Pulmonary Embolism - PE). Of those, 60,000 to 100,000 Americans die each year. 1

  • That's twice as many deaths than breast cancer. 10
  • Three times as many deaths than car accidents. 11

Warfarin is the most commonly prescribed anticoagulant medicine on the market. 2 It is prescribed to patients who have suffered from a DVT/PE.

1/3 of people who get a DVT have either Factor V Leiden or another genetic mutation. 8

Over 10 million people in the US have Factor V Leiden (about 4.4 percent of Caucasians have Factor V Leiden). The condition is less common in Latin Americans and African-Americans and is extremely rare in people of Asian descent. 6 7

Factor V Leiden is one of the most common Monogenic disorders in the Caucasian population. 7

Factor V Leiden Homozygotes have close to a 100% lifetime risk of a thrombotic event. 8

Warfarin is ranked first in number of deaths for drugs causing "adverse effects in therapeutic use". Beating out Insulin. 3

In total in the U.S. alone 20 million people are on Warfarin, and each year 2 million new patients are prescribed Warfarin. 4

Warfarin is effective but is tough for patients and doctors to manage because Warfarin interacts with most medicines and foods. Failing to manage the Warfarin can lead to death via the blood clot or an extreme bleeding event. Patients take blood tests called INRs to make sure they are taking the correct dosage. 5
