Why Outsourcing Beats In-House in U.S. HealthTech Projects: A Case Rooted in Clinical Data Monitoring


In the U.S. HealthTech industry, time to market, data security, and regulatory compliance are non-negotiable. But even well-funded teams with in-house developers often find themselves in a quandary: they are overwhelmed by competing priorities, lack industry expertise, or can't move fast enough to meet release deadlines.
This article discusses how outsourcing helped a U.S. healthcare company build a clinical data monitoring tool faster, safer, and with tighter controls than an in-house team could have done. It also explores why outsourcing is often the more strategic choice in 2025.
The Project Context
The client is a U.S. HealthTech company with an in-house backend system that is already up and running. They needed to build a clinical data monitoring interface that would:
- Integrate seamlessly with existing infrastructure.
- Handle sensitive patient data under HIPAA.
- Offer a user-friendly dashboard for trial administrators and clinicians.
- Be delivered quickly, without disrupting the internal roadmap.
Their internal team was focused on core backend infrastructure. While capable, they didn’t have the bandwidth or specific expertise in data visualization and regulated interface design. The client needed a fast, compliant, and scalable solution—without hiring full-time.
Key point: This wasn’t a team that “couldn’t do it.” It was a team that didn’t have the right bandwidth or specialized roles at the right time. The result? Risk of project delays and regulatory exposure.
What an In-House Team Would Require
To build and maintain this type of clinical data monitoring system internally, a company would need:
- 2+ front-end engineers experienced in PHI-safe architecture.
- 1 UX designer familiar with clinical interfaces and dashboards.
- 1 DevSecOps engineer to manage secure infrastructure.
- 1 project manager with experience in HIPAA/FDA-compliant software delivery.
- Time and budget to recruit, onboard, and retain this team.
That’s at least 4–5 full-time hires. In 2025, hiring a senior developer in the U.S. costs around $160K–$190K annually, including taxes and benefits. Add recruitment time (8–12 weeks), onboarding, and the risk of team gaps—timeline quickly stretches beyond the planned release. Multiply that by 5 roles—and factor in ramp-up time—and total project costs could easily surpass $400K over six months.
Why the Company Chose Outsourcing
Rather than overburden their internal roadmap or spend months assembling a team, the company partnered with Darly Solutions, which already works with U.S. healthcare clients. Within 5 business days, a remote team was onboarded, including:
- Frontend developers with clinical data experience.
- A UX designer with multiple HIPAA-regulated projects behind them.
- A project manager and tech lead who took full ownership of the delivery.
They worked within the client’s architecture, maintained full transparency, and delivered a production-ready solution ahead of schedule. The client retained control over infrastructure, access, and IP without being pulled away from their core priorities.

Security Concerns: The Most Common Objection
One of the most common objections we hear from HealthTech companies in the U.S. is:
“If development happens outside our walls, how can we be sure our data and infrastructure are truly protected?”
The concern is valid, especially when you’re dealing with highly sensitive health data, clinical trials, and strict U.S. regulations.
In a recent conversation with a HealthTech executive, we heard this exact fear. His company works with external teams and handles massive volumes of sensitive patient data. His worry wasn’t about code quality or delivery speed—it was about not having full visibility and control over the systems and people handling that data.
He shared:
“Our internal teams understand exactly how and where data moves. But, it's harder to feel in control when we involve external partners, even with NDAs and contracts. And if something goes wrong—who's ultimately responsible?”
But Here’s the Reality: Control Comes from Process, Not Geography
The key misunderstanding here is that in-house automatically equals “safe”, and outsourced means “risky.” That’s not true.
Security in HealthTech doesn’t depend on where the team sits. It depends on how access is managed, how infrastructure is configured, and how compliance is enforced.
When working with an experienced HealthTech outsourcing partner, companies can enforce:
- Role-based access controls (RBAC) with audit trails.
- Environment isolation: dev/staging/production strictly separated.
- On-premises or private cloud deployment, under your control.
- Regular compliance checks aligned with HIPAA.
- Source code ownership and internal code reviews.
- Strict NDAs, DPAs, and custom security policies in place.
In fact, a structured outsourcing setup often introduces more formal security governance than internal “trusted” processes that lack documentation or auditability.
The Results
With outsourcing, the client:
- Delivered a fully compliant monitoring interface integrated into their existing system.
- Avoided delays tied to internal hiring or overcommitment.
- Retained full IP and infrastructure control.
- Passed HIPAA audit without revisions.
- Saved $250K+ compared to in-house staffing.
- Released the product to production 3 months earlier than initially projected.
And they did all of it without overloading their internal team.
Final Thoughts: Outsourcing as a Strategic Enabler
Outsourcing isn’t a workaround—it’s a way to move faster without compromising quality or control. For HealthTech companies, it can be the difference between hitting a clinical release window and missing it by quarters.
It's not about replacing your internal team. It's about unlocking execution capacity when you need it most—supported by specialists who know your industry and your risks.
Outsourcing done right gives you:
- Faster time-to-market.
- Lower delivery costs.
- Full security and compliance.
- Experienced teams on demand.
- Predictable outcomes with shared accountability.

With more than 2.7 billion smartphone users across the world in 2020, it’s no surprise that the mobile app industry is expended with no signs of stopping. Nowadays, smartphones have become a useful and convenient instrument that offers multiple benefits such as communication through emails and social networking, web surfing, entertainment, GPS and various other productivity apps.
In fact, studies show that the average American checks their phone every 12 minutes. 10% of people check their phones every four minutes.
We use our phones every day at work, at home, on the street, in bed, while we are eating, in our cars. You might be reading this article from a mobile device right now.
What are people doing on their phones? Well, 90% of mobile time is spent on apps.
According to these facts, many companies considering mobile apps are facing a common challenge — which app development approach to choose? Should we build a native, mobile web, or hybrid app? More importantly, which is the most appropriate app type for you and your business?
Let’s find out what are native, mobile web, and hybrid apps, analyze the differences between them, as well as the advantages and disadvantages of each. After reading, you will be able to understand which approach will be the right one for your business idea.
Web Apps
A web app is a software program that uses web technologies like HTML5, CSS, JavaScript. It exists entirely within browsers such as Safari and Chrome and is essentially a mobile website. It is therefore not possible to download them from an app store.
Also, the web app is not connected with the device’s operating system and does not use its storage. Unlike an iOS or Android app, there is no software development kit (SDK) for a developer to work with. There are templates and frameworks for developing web apps like Angular, React, and Vue.js that you can use to get a quick start.



So, here are some pros of web application
- Developing a web app can be simple and quick. So, web apps are a cost-effective way to put your product in the hands of a lot of users.
- Web apps can be built for all platforms as long as they can run in an appropriate web browser.
- The user doesn’t have to manage updates manually. The newest version always loads when a user opens a web app.
And some cons:
- Searching for an app might be difficult because the user doesn’t find it in any app store.
- A browser is required to run a web app. It means that users have to take more steps to use a web app, whether that’s searching for the page or typing in a URL.
- Web apps can be slower and lack a lot of benefits. They only work online and they don’t have access to as many phone features like push notifications, contacts, etc.
However, as browsers and web apps become more advanced, PWAs (progressive web apps) offer a wider functionality like:
- Sending push messages
- Using some touch screen elements
- Using some of the device’s hardware
So, If your startup is on a budget and doesn’t require complex functionalities or access to operating system features, then building a web app can be the most suitable solution.
Native Apps
A native app is a software application that is built for specific platforms and is written in languages that the platform accepts. For example, Swift and Objective-C for native iOS apps, Java or Kotlin for native Android apps and C# for the most part for Windows Phone apps. Native apps are also built using the specific Integrated Development Environment (IDE) for the selected operating systems.
Advantages of the native application:
- Native apps offer the fastest, most reliable and most responsive experience to users.
- Good integration with the hardware of the device (e.g. camera, GPS, phone, touch screen)
- It comes with the push notification functionality.
- Great design and user experience possibilities. For example, the implementation of sophisticated UI/UX design and animation.
- These apps can be downloaded from app stores and installed on mobile devices, where they can be placed as a designated icon on the home screen.
- Native apps are also more suitable for working offline.
Disadvantages:
- Need more than one codebase. iOS apps will not run on Android and the opposite, so you will have to work with different codebases for every platform you choose to build in.
- Native apps are usually more expensive in developing, especially for companies that need apps on multiple OS platforms. For both platforms, it will require two separate developers or teams.
- A lot of time is spent on development. Also, it takes time to update the app for different platforms.
- Require constant updates to keep with the current OS versions.
- Expensive to keep your native app updated
- Both Apple App Store and Google Play get a 30% commission from every in-app payment.
To sum up, a bigger budget is required if you want to build your app for multiple platforms (i.e. iPhones and Android) and to keep your native app updated. Native apps are not the best option for simple applications.
By offering a great user experience, better performance and accessibility, native apps are able to offer users a more personalized product.
Hybrid apps

Hybrid apps combine the power of native and web apps to reap the benefits of both. Actually they are made, so they look and feel like native applications, but like web apps, are built with JavaScript, HTML, and CSS. Also, there is a shell that is downloadable and loads the code using a WebView.
Advantages of the hybrid apps:
- Hybrid apps don’t need a web browser like web apps.
- With a hybrid app, you only have one codebase to manage. So, instead of building two apps like with native apps, you’re building one app, and it works on both platforms.
- Hybrid app developers are often less expensive than native application developers. You will probably require half the number of developers two native apps would have required. Or, with the same number of developers, a hybrid app could be published in half the time.
- Hybrid is a great option for developers that create visually intense applications, for instance, games
- Hybrid apps let you retain the same ability to access device features as with native apps.
- Easy to work with, maintain and upgrade
- Because of their native infrastructure, hybrid apps can work offline.
- Hybrid apps are easier to scale to another platform. Once you’ve built for one platform, you can launch on another, like Windows Mobile.
The downside:
- Getting your hybrid app to run appropriately on each platform generally takes substantial work. Sometimes, the total cost might become comparable to that of fully native apps. It all depends on how close you want to get to the “native user experience” or how simple your app is.
- Hybrid apps can be slower than native apps.
- Need to customize to a large number of exciting browsers
- Inability to implement complex features (e.g. in-app analytics, charts, diagrams)
- These hybrid systems make bug fixing more difficult.
- Hybrid apps load in a WebView, so performance can be worse than native applications.
Say you have an idea for an app, and you don’t know if people will like it or not. If you understand that a web app doesn’t really allow you to test this app, the simple version of the hybrid app will be a good solution for you.
You give to people to download and use the app on their device, although you are short on resources. Usually, a startup project is decided to create a hybrid app that in the startup world, this is called an MVP, or minimum viable product.
Conclusion
There are many different directions in which you can take your app, all of which have their pros and cons. The choice between web, native, and hybrid development is dependent on a number of factors, including business needs, app requirements, developer skill, budget and timelines. What’s important is to spend enough time thinking and analyzing before you start building because the apps are expensive enough. So, you may only have one go at getting it right. Find out the information as much as you can about the different kinds of apps and the development stages.

Checklist on How to Choose a Country to Outsource Software Development
Having plenty of IT outsourcing services offers to choose from is surely good. Where competition is intense, the quality is always good. At the same, the prices are balanced under such conditions. On the other side, choosing among multiple offers is a bit time-consuming. The below criteria will help you to sort all the available options out faster:
- Quality is a primary aspect to take into account. Cheaper never means better. In fact, it may turn out that low-quality products may take even more funds, especially, when it comes to corrections. However, the complexity of the task should be kept in focus as well. For more complicated assignments, the quality of outputs has to be superb.
- Tech education – the specialist you would like to assign should have sufficient tech background and skills. Emphasize whether a provider draws attention to the ongoing training. In addition, true IT experts should be ready to address the specifics of your projects effectively as well. Therefore, take time to discuss this aspect in advance.
- Cultural aspects – this nuance is often underestimated, however, it plays a great role. There are jurisdictions that are closer to the Western standards. However, some states are more keen on preserving their local specifics. Make sure you understand it well while being on the shore.
- Timezone – the perfect option in this case is nearshore software outsourcing. When your state is adjacent to the neighboring one where you decide to hire developers, it is always possible to arrange a closer collaboration. If you consider developers from the other part of the globe, make sure you have at least 3-4 hours of overlap.
- English proficiency – price and quality can mean nothing if there is a significant language barrier. While choosing your service provider, ensure developers have sufficient English level. Upper-Intermediate will work well for projects that do not require your constant supervision. However, more complicated ventures, especially innovative ones, will definitely require a more advanced level.

Challenges in Fitness Tracker App Development
Fitness tracker apps have revolutionized health monitoring, but their development is fraught with challenges. Four key hurdles stand out:
Ensuring Accuracy of Health Data
Accuracy of the health data is the backbone of any fitness tracking app. Users depend on metrics like step counts, heart rate, and calorie burn to make informed health decisions. Inaccurate data can mislead users, erode trust, or even pose health risks. Poor sensor quality, flawed algorithms, and inconsistent user input contribute to this challenge.
Solutions:
- High-Quality Sensors and Algorithms: Developers should use reliable sensors and collaborate with health experts to design precise algorithms. These algorithms must be validated against benchmarks to ensure metrics align with real-world outcomes.
- User Input Optimization: Create intuitive interfaces that encourage users to input accurate details (e.g., age, weight) and include calibration features to account for variables like terrain or weather.
- Continuous Refinement: Regularly update algorithms based on user feedback and emerging research to maintain accuracy over time.
User Privacy and Data Security Compliance
Health data is highly sensitive, and users expect it to be protected. Developers must comply with strict regulations like GDPR (General Data Protection Regulation) and HIPAA (Health Insurance Portability and Accountability Act) while safeguarding against cybersecurity threats. A breach can damage user trust and result in legal consequences.
Solutions:
- Robust Encryption: Implement strong encryption for data both in transit (e.g., during syncing) and at rest (e.g., in storage) to prevent unauthorized access.
- Regulatory Compliance: Secure explicit user consent for data collection and anonymize data used for research or analytics to meet legal standards.
- Proactive Security: Use two-factor authentication and conduct regular security audits to stay ahead of evolving threats.
Device Compatibility and Integration Issues
Fitness tracking apps must function seamlessly across various devices, operating systems (e.g., iOS, Android), and third-party platforms (e.g., Apple Health, Google Fit). Variability in hardware, differing OS APIs, and high battery consumption complicate this process, potentially leading to inconsistent user experiences.
Solutions:
