Denver, Colorado
A Denver web design agency
that builds for leads.
Nerd Stack is a Denver web design and development agency with 9+ years of experience building conversion-focused websites and custom software for small and medium businesses. We design for measurable outcomes — leads, bookings, and revenue — not just aesthetics, and we build everything from custom marketing sites to client portals and custom web apps. Every project qualifies for 0% financing with no down payment.
Why Nerd Stack
What sets us apart from other Denver web design companies.
Conversion-focused, not just good-looking
Most Denver web agencies design sites that look fine and do nothing. Every layout, headline, and CTA we build is driven by one question: does this make someone pick up the phone or fill out a form?
9+ years and a real case study portfolio
We've been building websites in Denver since 2017 — across finance, beauty, golf, AI software, agency partnerships, and more. Every project on our work page is a real client with real outcomes.
We build custom software, not just websites
When a Denver business needs more than a marketing site — a client portal, a custom admin system, an event platform — we build that too. Few local agencies can take a project from brochure site to custom web app.
Performance and SEO built in from day one
Sub-1.5 second load times, 90+ Lighthouse scores, and a full technical SEO and AEO foundation on every build — because a beautiful site that no one finds doesn't generate leads.
0% financing, no down payment
Every project qualifies for 0% financing. The upfront cost of a professional website is never the reason a Denver business has to settle for a template.
You own everything
Code, design files, domain, content — all yours at handover. Nothing held on a proprietary platform, nothing locked behind a subscription you can't leave.

Denver web design FAQ
What does a Denver web design agency cost?
In Denver, a professional business website typically costs between $2,000 and $15,000+. Simple brochure sites run $2,000–$5,000; standard custom sites with design, SEO, and a CMS run $5,000–$12,000; complex builds and custom web apps start at $12,000 and go up. Nerd Stack offers 0% financing with no down payment on every project. See our full Denver web design cost guide for a complete breakdown.
What makes Nerd Stack different from other Denver web design companies?
Three things: we design for conversions, not just aesthetics; we build custom software and web apps, not just marketing websites; and we have a real case study portfolio across multiple industries. We're also a small, accountable team — you work directly with the people building your site, not a rotating cast of account managers.
Do you only work with Denver businesses?
We're Denver-based and we know the local market, but we serve clients nationwide. Most of the work happens over video calls and shared documents regardless of location. That said, for a Denver business targeting Denver customers, working with a local agency that understands the market is a real advantage.
How long does it take to build a website?
Most custom websites take 6–10 weeks from discovery to launch. Redesigns are similar. Custom web apps take longer and are built in phases. We give you a realistic schedule before the project starts — and we don't quote timelines we can't hit.
What platforms do you build on?
Our default is Next.js — it's faster, more secure, and better for SEO than most alternatives. We also build on WordPress with custom themes and plugins when a project calls for it. We choose based on what your project actually needs and what your team can maintain.
Do you help with SEO?
Yes — technical SEO is built into every project: site structure, Core Web Vitals, schema markup, canonical URLs, sitemap, robots.txt, and metadata. We also build for Answer Engine Optimization so your business can be cited by AI tools like ChatGPT and Perplexity. Ongoing SEO content strategy is available as a separate engagement.
