Websites and web apps that do what they say they'll do.

Letter Box Digital builds bespoke websites and web applications. They look sharp, they work without fail, and they turn visitors into customers. That's the whole point.

The approach

We start with what it needs to do. Then we sweat the details.

Every project starts with the same question: what does this actually need to do? The answer shapes everything, from the architecture down to the letter-spacing.

Design that converts

Build something that tells the story and drives the action that matters: the call, the booking, the sale.

It has to work

A beautiful site that breaks is a broken site. Everything ships tested, fast, and accountable: forms that deliver, pages that load, promises kept.

AI-first, founder-built

An AI-first process keeps costs low and delivery fast, without a layer of handoffs. The person who designs your project is the person who builds it, end to end.

What AI-first means

The work

Two kinds of projects. One standard.

Websites that represent a business with precision, and web applications that do one specific thing exceptionally well. All three are live. Go see for yourself.

Website · henrymeigs.com

A real estate practice, built from scratch

A custom site for a Philadelphia REALTOR®: nine neighborhood market pages updated monthly, interactive demand charts, buyer and seller guides, and a strict editorial design system. No template touched this site, and it looks nothing like this one. Every client gets their own identity.

Web application · Pathway

One map widget, embedded anywhere

Pathway turns any address into a curated, interactive neighborhood map that drops into a listing page with one line of code. Live travel times, Street View, per-pin analytics, and Stripe-powered subscriptions. It does a specific thing, and it does it completely.

Online store · endurecoolpatch.com

A single-product store, built to sell

A custom Shopify store for the Endure Cool Patch, a clear peel-and-stick hydrogel cooling patch sold as a 10-pack. We stripped a Dawn theme to its frame and rebuilt it into a liquid glass design system: frosted translucent panels, blur, and depth across the product page, cart, and checkout, styled down to the snippet. Built mobile-first for how customers actually shop. A real store, made to sell.
