Healing the Bill with Blake Walker, Co-founder & CEO of Inbox Health 

Blake Walker is the co-founder and CEO of Inbox Health, a company dedicated to transforming the patient billing experience in healthcare. He has focused his career on design and innovation in the patient billing space and played a pivotal role in developing technologies that simplify medical billing for patients and healthcare providers alike. Under his leadership, Inbox Health has become a trusted partner for more than 3,000 healthcare practices and more than 2 million patients a year, and was recently named to the Inc. 5000 list of fastest-growing private companies in America. 

Healthcare billing is notoriously chaotic. What was the specific moment you saw a broken system and thought “I can fix this” — not just improve it, but fundamentally reimagine it? 

Like many founders in healthcare technology, our starting point was personal: we had our own frustrating experiences as patients trying to understand medical bills. But what stood out to us was that the problem wasn’t just billing — it was communication. 

Providers often struggled to clearly explain costs and insurance coverage at the front desk. Patient statements were largely one-way communication, sent outbound with no easy way to ask questions or resolve confusion. And if patients did try to call for help, support centers were often difficult to reach and rarely able to provide clear answers. 

At the same time, patient responsibility has grown dramatically — in many cases, representing up to 30% of a provider’s revenue. Yet many organizations were still relying on manual, paper-based billing processes that delayed payments, increased write-offs, and created an administrative burden. 

We founded Inbox Health to approach patient billing as a communication platform rather than just a payment problem — making it easier for providers to clearly explain balances, answer questions, and help patients resolve bills quickly and confidently. 

Inbox Health reports that 50% of patients leave a practice over a billing issue. That’s a staggering statistic. When you first started presenting this problem to investors or partners, did people believe you — or did you have to fight to make them see what you were seeing? 

An antiquated and poor patient billing experience was a driving factor for why we started Inbox Health, but for practices, partners, and investors, the value goes beyond the patient. Independent practices, billing companies, and large healthcare groups are missing out on revenue opportunities and spending too much staff time managing patient billing. These inefficiencies are costly, especially given the shift to patients taking on a larger portion of healthcare bills. The proof of Inbox Health’s value lies in our results, and the impact is immediate. Healthcare groups see a 5x increase in collectible payments, a 20% increase in patient billing revenue, and cut the time spent on patient A/R in half. 

Inbox Health’s technology utilizes automated billing cycles to reach patients on the right channel, at the right time, with the right message. When patients have questions about their healthcare bills, an AI assistant is available 24/7 to respond and resolve the majority of common inquiries and quickly escalate to a live agent if necessary. Patients easily pay via credit card, digital wallet, ACH, or paper mail through a secure, easy-to-access portal – no username or password required. If patients prefer to pay over time, they can easily set up a payment plan directly through the portal. Inbox Health integrates with the most-used practice management systems, so managing patient A/R fits into billing teams’ existing workflows. 

You’re solving for two completely opposite audiences simultaneously: billing companies who want efficiency and revenue, and patients who are often stressed, confused, or scared when they get a medical bill. How do you design a product that genuinely serves both without compromising either? 

Inbox Health’s solution is mutually beneficial for both billing teams and patients. Across both segments, our advantage comes from combining data-driven outbound billing communications with a best-in-class patient support experience. The result is that providers collect more, faster, without adding work for their teams. Patients receive timely bills that are transparent, access 24/7 support when questions arise, and feel confident settling their balance with their preferred payment method. 

Many of the questions patients ask practices — whether about bills, balances, insurance, or basic administrative issues — are repetitive but time-consuming for staff. Our goal is to enable providers to handle these interactions instantly across phone, text, email, and real-time chat, while allowing the AI to take action such as processing payments or setting up payment plans. We’re also focused on bringing real-time chat more deeply into the provider workflow by integrating it directly with billing and EHR systems, giving patients faster answers while reducing administrative burden for practices. 

AI is now embedded into your platform — handling 70% of patient billing inquiries without staff involvement. Where’s the line for you between AI that helps and AI that removes the human moment patients sometimes need in a healthcare context? 

AI isn’t replacing human moments — in fact, it’s making the moments that require human interaction more personal and empathetic. Think of an AI assistant as the first line of defense that can handle common patient inquiries 24/7, reserving more complex questions for human agents. The AI assistant collects information, and complex issues are then escalated to human agents who start the conversation more equipped to respond with relevant details on hand. We live in a world where consumers expect to have their questions answered immediately and accurately, and the reality is an AI assistant is able to meet those goals for the majority of inquiries — sending statements, how to make a payment, date of service details, and payment reasons, to provide a few examples. Our data shows 95% of patients report a positive interaction with our AI assistant. 

What’s a strategic bet Inbox Health made early on that felt risky at the time but turned out to be one of the best decisions the company ever made? 

Over the past decade, Inbox Health has become the dominant patient billing platform in the third-party billing and RCM market. That position came from solving a very specific problem early on: patient billing in ambulatory care spans dozens of EHR and practice management systems. Making it work well required deep integrations and years of optimization across those workflows. 

Many patient billing vendors operate one step removed from the operational systems, working primarily off statement files or batch data exports. We took a different approach and invested heavily in direct integrations across the ambulatory ecosystem. That allowed us to understand how patient billing actually behaves across different specialties, payer mixes, and operational models, and to design workflows that improve both patient outcomes and staff efficiency. 

In the last three years, we’ve shifted our focus from outsourced billing companies to mid-size and large provider groups that face many of the same complexities as RCM firms — multiple systems, high patient responsibility balances, and growing pressure to improve the patient experience while maintaining operational efficiency. 

With the rise of high-deductible health plans, patients are increasingly responsible for a larger share of their medical costs. Does that shift make Inbox Health’s mission more urgent — or does it change what you need to build? 

The impact of high-deductible plans is becoming harder for providers to absorb as patient balances make up a larger share of revenue — and incentives to pay grow weaker. The pain point is most evident during the first quarter of the year after deductibles reset. For billing teams, that means a surge of patient questions, a dip in revenue, and overdue balances. 

Providers now have to compete on the strength of their communication: how clearly they explain charges, how quickly they respond, and how effectively they build trust in every interaction — and that is where Inbox Health comes in. 

Inbox Health is approaching its tenth year. Looking back at the journey — how has the company evolved, and what is driving you forward now? 

Healthcare is an evolving industry, and Inbox Health has evolved with it. Our ability to adapt and continue to innovate keeps us going. 

Over the next 12 months, we’re focused on two areas where we believe the industry is about to change meaningfully: card on file and AI-driven patient support. 

On card on file, the industry has traditionally treated it as a front-desk policy. We think it’s actually a patient engagement workflow that spans the entire visit lifecycle. Our focus is on optimizing three key interaction points where patients are most receptive: pre-visit, in the office, and post-visit during digital checkout. The goal is to make it seamless for providers to capture payment methods and enable autopay without mandating it or creating patient friction. 

That foundation enables a more intelligent post-visit billing workflow that recognizes the financial realities patients face. Instead of treating every balance the same way, we dynamically offer payment plans and financing options that meet patients where they are. 

The second focus area is AI-driven patient interaction. Many of the questions patients ask practices — whether about bills, balances, insurance, or basic administrative issues — are repetitive but time-consuming for staff. Our goal is to enable providers to handle these interactions instantly across phone, text, email, and real-time chat, while allowing the AI to take action such as processing payments or setting up payment plans. We’re also focused on bringing real-time chat more deeply into the provider workflow by integrating it directly with billing and EHR systems, giving patients faster answers while reducing administrative burden for practices.
