Bits&Letters

Bits&Letters is proud to sponsor Astro, the best modern framework for delivering content-driven experiences that perform flawlessly and delight your users.

We’re a web & AI consultancy based in NYC founded by David Demaree, longtime design engineer and alumnus of design platform teams at Adobe, Google, Stripe, and Webflow.

Unlike a lot of agencies, Bits&Letters is developer-led and unabashedly technical. Our strong engineering and systems chops are paired with a strong design sensibility. Whether we’re designing your site or working with your designers, our senior, experienced team sweats the details to get everything right the first time.

For example:

• We helped Rill replace their Webflow-powered site with a codebase their team (and AI agents) could update, including a Sanity-powered page builder so they can spin up new pages quickly without a deploy.
• For Everself, we delivered an Astro build — complete with high-resolution images and video — with flawless Lighthouse and Core Web Vitals scores in just 8 weeks.
• Our founder David wrote Git for Humans for the now-shuttered, much beloved tech publisher A Book Apart; Authors Together is a directory helping readers find ABA authors’ books new homes. Both the directory and the GfH site are static sites powered by Astro.

What clients say about us

Our new website looks so good and is amazingly fast. This launch really made it feel like a new chapter starting for us.

— Paige Schwartz, CEO at Copytree

B&L helped us scale from our day-one build to a site that runs like it’s backed by a full design team. They gave us the systems, structure, and speed to keep up with growth—without adding overhead.

— Stephie Glaser, Developer Marketer at Oso

The details that matter

Every site we build meets WCAG accessibility standards, follows security best practices, and performs well on slow connections. These aren’t extras we bolt on at the end—they’re built into our process from day one, so your site works well for everyone who visits it.

Deep collaboration, direct access

You shouldn’t have to wonder if your project is on track, or wait for the next meeting to ask a quick question. Every client project gets a dedicated, shared Slack channel and Notion workspace, in addition to regular video calls and status reports.
