Websites That Work as Hard as You Do

At Xcelacore, we help businesses in Oak Brook and surrounding areas build modern, high-performing websites that actually support growth. Whether you need a new site from scratch or want to rebuild what you already have, we focus on clean, functional design and reliable performance, not trendy fluff that slows you down. Your website is more than just a digital business card. It’s your first impression, your sales team, and your storefront, especially if customers or clients are coming to you online. We make sure it does the job right.

We build with growth in mind. Our development process ensures your website is not only secure but also able to scale as your business evolves.

We connect your website to the tools you already use—CRMs, ERPs, payment systems, or third-party apps—so your data flows where it needs to go.

CMS Integration

—

Need control over your own content? We work with platforms like WordPress, Drupal, and headless CMS systems, giving you the ability to make updates without needing a developer.

How We Work

—

Xcelacore follows agile project management (APM) standards for most projects. You and your team will be assigned a dedicated project manager who will oversee the entire project from requirements gathering through execution.

We Start with the Why

What’s the goal of your site? More leads? Better brand image? Faster loading times? We start by understanding what matters most to your business.

We Design with Purpose

User-friendly layouts, modern design, and fast load times, our design team builds with the end user in mind, not just aesthetics.

We Develop and Test

Our developers bring the design to life and test across devices to make sure everything works exactly as it should.

We Support and Improve

Even after launch, we’re here to help with updates, changes, and improvements as your needs shift over time.

Success Stories

—

We start by understanding business objectives and requirements with technology strategies. Then our work focuses on the implementation of digital technology solutions that drive businesses forward.

Director of Communication
@ Associated Colleges of Illinois

“It’s not often that you can work with outside developers, consultants, who truly have your best interests at heart. At every step of the process from architecture to deployment and testing, and at a fraction of the cost of in-house development work has been a dream come true. I can’t speak highly enough of the whole team. Their ability to forecast and deliver on time and within scope is really good. They come with my highest recommendation. These guys are true winners.”

Your Website Shouldn’t Be Holding You Back

—

Too many businesses settle for websites that look good but don’t actually work. Slow load times, confusing layouts, and a lack of clear messaging can cost you customers and credibility. That’s where we come in.

At Xcelacore, we build websites that are easy to use, easy to update, and built to grow with your business. You won’t have to chase down developers for small changes or deal with outdated plugins that break everything. We build it right the first time, and we’re here when you need us after launch. If you’re in Oak Brook, IL, and you’re ready for a website that reflects where your business is going, not where it’s been, let’s talk.

Not at all. While we’re based in Oak Brook, we work with clients all over Illinois and the U.S. But if you’re local, we’re happy to meet face-to-face.

We do both. Whether you need a total overhaul or just want to modernize certain parts, we’ll work with what you’ve got—or help you start fresh.

We can help with that. While we don’t provide hosting directly, we’ll set everything up and recommend the best options. We also offer ongoing maintenance if you want us to manage updates and security.

It depends on the scope, but most sites take between 4 to 8 weeks from start to finish. We’ll give you a clear timeline before we begin.
