Results, not jargon

What a faster site actually means for your business

Google uses Core Web Vitals as a ranking signal. A one-second delay in load time reduces conversions by 7%. If your current site takes 4-5 seconds to load, you're losing leads to competitors who rank above you—and losing the ones who do land on your page before they ever read a word.

100/100 Lighthouse scores.
Every page we ship hits perfect scores for Performance, Accessibility, Best Practices, and SEO—the scores Google uses to rank your site.
Sub-second load times, globally.
Deployed on Cloudflare's global edge network. Your site loads fast whether visitors are in New York, London, or Tokyo—no server in a single data center choking under load.
Zero plugins to break.
No WordPress core updates, no plugin conflicts, no PHP vulnerabilities. Static sites have no attack surface—they literally cannot be hacked the way WordPress can.
Hosting that costs $0–$20/month.
Cloudflare Pages and Netlify serve static sites for free or near-free. No expensive managed WordPress hosting, no server bills that scale with traffic spikes.
Built-in SEO and sitemap.
Every page is server-rendered HTML—fully readable by Google without JavaScript execution. Automatic sitemaps, canonical tags, and Open Graph metadata included.
Easy content updates.
Update copy yourself via markdown files, or we can integrate a headless CMS like Sanity for a familiar editing interface—without sacrificing performance.

What we build

The right tool for marketing-driven sites

This approach isn't the right fit for every project—but for sites where SEO, speed, and conversion are the primary goals, nothing comes close.

Marketing & Landing Pages

Campaign pages, product pages, and full marketing sites. High-converting layouts built to capture leads and rank for competitive keywords.

Blogs & Content Sites

SEO-optimized blogs that load instantly and handle any amount of content. Ideal for organic traffic strategies and thought leadership.

Company & Portfolio Sites

Professional company sites with case studies, service pages, and contact flows. Built to make a strong first impression and generate inbound leads.

Why switch

How this compares to WordPress and page builders

10x faster than WordPress.
A typical WordPress page takes 3-6 seconds to load. Our sites load in 300-500ms. That's not a small improvement—it's a different category of experience for your visitors and Google's crawler.
No page builder lock-in.
Wix, Squarespace, and Elementor trap your content in proprietary formats. Your new site is clean HTML and Markdown—you own it outright and can take it anywhere.
No more security patches.
WordPress sites get compromised every day. Static sites serve pre-built files—there's no database to breach, no PHP to exploit, no plugin vulnerabilities to patch on a Sunday morning.
Scales to any traffic spike.
Your WordPress server can buckle under traffic from a viral post or a marketing campaign. Edge-deployed static sites serve millions of requests without breaking a sweat—or sending you a hosting invoice.
