Web Development Company in Chicago

We build web applications that hold up after launch: real traffic, real data, and a codebase your team can still change in year three.

We Are Actually in Chicago

An office in the Loop

20 N Wacker Dr, Suite 1200, in the Loop. A lot of the pages competing for Chicago software searches come from firms with no office in the city, so check this about every firm on your shortlist, including us.

The builders, by name

The people on your project are listed below with their roles, not a bench that appears after the pitch.

Reviews on Clutch

Our reviews sit on Clutch, which we do not control. If a firm cannot show you a named team and outside reviews, that is worth knowing before the contract.

Where Web Projects Usually Come Unstuck

Web development in Chicago covers everything from a marketing site to a marketplace handling money, so the failure modes are different depending on which end you are at. These six cover most of the calls we take.

The site is a brochure, the business needs a tool

The website describes what the company does. Meanwhile the actual work happens in spreadsheets, email threads and a portal somebody bought in 2019. The site and the business have almost nothing to do with each other.

What we usually find

The gap is not a design problem. The operations that should live on the web were never modeled, so nobody ever specified them. That work is a discovery exercise, not a redesign, and doing it as a redesign is why the last attempt did not stick.

Every change needs a developer

Marketing wants to publish a page and has to file a ticket. The ticket waits behind product work. Six weeks later the campaign has moved on and the page ships anyway, into nothing.

What we usually find

The content model was built for the first five pages and never generalized. Either the CMS is wrong for the team, or the right CMS was configured as if every page were bespoke. Webflow solves this well for marketing sites; it is a poor answer for an application, and the two often get confused.

It falls over exactly when it matters

The launch goes well until it goes well. Traffic arrives, the database starts timing out, and the fix is a bigger server every time until the bill is the problem instead.

What we usually find

Almost always a query pattern rather than a capacity problem: something that ran fine against a thousand rows and does not against a million. Bigger hardware buys time and hides the cause. We profile before we provision.

Integrations break quietly

The CRM sync, the payment webhook and the inventory feed all worked at launch. One of them has been failing for three weeks and the first anyone knew was a customer complaint.

What we usually find

The integrations were built as happy paths with no retry, no dead letter queue and no alerting, because none of that demos. The fix is unglamorous and it is the difference between a system you can trust and one you have to check.

The rebuild quote is bigger than the original build

You asked three firms what it would take to modernize the site. All three came back proposing to start again, at a number nobody expected.

What we usually find

A full rewrite is the easiest thing to quote and the most profitable to sell, which is worth knowing when three of three recommend it. Often the front end is the part that is genuinely tired and the data layer underneath is fine. Separating those two questions changes the number substantially.

Nobody can say what the site is doing

You have analytics installed. You still cannot answer which pages bring in qualified enquiries, or what happens between someone landing and someone filling in a form.

What we usually find

Tracking was installed once and never mapped to the funnel the business actually cares about, and campaigns ran untagged. UTM data cannot be reconstructed after the fact, so the first fix is always tagging discipline going forward rather than an archaeology project on the past.

What We Build on the Web

Six practices, delivered by one Chicago team. Most web projects use three or four of them, which is the argument against splitting design, front end and back end across separate suppliers.

Web Application Development

Operator dashboards, internal platforms and customer portals: the software your business runs on rather than the site that describes it. Built so a new engineer can find their way around it in a week.

Marketplaces and Ecommerce

Two-sided platforms where both sides need to trust the numbers: catalogs, carts, bulk ordering, payments and the reconciliation nobody thinks about until it is wrong. Leaf Trade is the clearest example of ours.

Front End Engineering

Interfaces that stay fast on a mid-range laptop over hotel wifi, not just on the machine they were built on. Accessible markup, sensible state management and a component set your team can extend.

APIs and Integrations

Connecting the systems that were never designed to talk: CRMs, payment providers, logistics feeds, internal databases. With retries, monitoring and alerting, so a silent failure is not discovered by a customer.

Websites and Webflow

Marketing sites your team can actually update. Webflow is our stated go-to for modern websites and we have published on why, but it is a recommendation rather than a default. An application does not belong in a site builder.

Performance and Maintenance

Taking on a site or application somebody else built, finding out why it is slow, and keeping it running. This is a large share of the work and it rarely starts with a rewrite.

Web Work We Can Show You

Four builds, four different shapes of web project. Open each case study and read the numbers there rather than trusting the ones on this page.

A marketplace, a logistics platform, a records retrieval platform and a marketing site with a design system, all built from Chicago. We do not publish client head office locations, so read these as our work rather than as a claim about where each company sits.

How We Work

Three steps to a plan, then phased delivery. The part most web agencies leave out is at the bottom.

How we handle scope changes. Scope moves on almost every software project, and pretending otherwise is how budgets get broken quietly. We price and sequence in phases so a change is a decision you make at a milestone with the cost in front of you, rather than something you discover in an invoice. Our Clutch reviews are public, including the ones that mention budget and schedule, and we would rather you read them before the call than after it.

1

Let us connect

You talk to product people and an engineer rather than a sales rep, often the same day you get in touch. We want to hear the problem before the feature list, because the feature list is usually somebody’s first guess at a solution and it is worth testing.

2

We move quick

You get a custom development plan within a week: scope, sequence, the team assigned, what the first milestone proves and what it costs. The plan is yours whether or not you continue with us, which is deliberate. It is hard to compare quotes when nobody will write down what they actually mean.

3

Meet the team

Phased execution with the named engineers who will do the work, not a bench you never see again after the pitch. You get a working increment early rather than everything landing at the end, because that is what makes a change of direction affordable instead of catastrophic.

Ways to Work With Us

A four week Webflow build and a platform with a two year roadmap should not be bought the same way, so we do not pretend otherwise. Here are the four models with their drawbacks attached.

Hourly

For moving scope or ongoing support. Billed by time worked, so you can stop any time. Harder when you need a fixed budget first.

Fixed cost

For a build with a clear finish line. One price per phase, agreed up front. Harder when each mid-phase change means a re-quote.

Staff augmentation

For engineers working inside your own team. Billed monthly per engineer, rolling with notice. Harder when nobody on your side can direct the work.

Custom

For discovery, a first release, then a live roadmap. Fixed to launch, then hourly or monthly. Harder for projects under about six months, where the model is overkill.

Tell Us About Your Web Project

A short conversation with a Chicago engineer and a product person, not a sales sequence. If we are not the right fit for the build we will say so on that call. Or call 312‑298‑9598, or visit us at 20 N Wacker Dr in Chicago.
