TechFoundry.io — Fast on Purpose: 96/100 Website Grade

TechFoundry runs two businesses on one website: AI & Software at /ai and Aerless™ telecom hardware at /aerless, under a corporate hub. I built the site as a hand-coded WordPress theme in September 2026 and wrote that story up separately. This case study is about one property of it: speed, and how we check it honestly.

On 2 October 2026, HubSpot Website Grader scored techfoundry.io 96/100. The homepage test reported 416 KB of page weight, 15 requests and a 1.6-second load. This is a snapshot of the current site, not a before-and-after against the old one.

Two audiences usually means two of everything: two heroes, two sets of plugins, a page builder to make the second section look different, and a theme that loads all of it on every page. A software buyer arriving with a workflow problem and a network engineer looking up a transceiver part number both end up paying for assets meant for the other.

Three decisions did most of the work.

One hand-coded theme, no page builder. PHP templates, one CSS design system and vanilla JavaScript for the animated heroes. There is no framework and no builder runtime, so a page ships only the markup and styles it uses. Section context decides which company you are looking at, not a second theme.

Three surfaces, one set of parts. The corporate hub, /ai and /aerless share the same header and footer logic, the same design tokens and the same content model. Nothing is duplicated to make the hardware side look like a different company.

Structure instead of weight. Product pages carry structured metadata (including Taiwan manufacturing origin for the optics and cable range), articles and products get page-specific sharing images, and editorial cards stay compact across screen sizes. The site reads as rich without carrying heavy media.

HubSpot Website Grader, homepage test, observed 2 October 2026.

Overall 96/100. Performance 26/30. Basic SEO checks 30/30. Mobile checks 30/30. Security checks 10/10. Homepage: 416 KB, 15 requests, 1.6 s reported load time.

For a second opinion, Lighthouse 12 on 24 September 2026: home desktop 98/100/100/100 with LCP at 0.7 s; /ai desktop 99/96/96/100; /aerless mobile 99/97/100/100. Home on mobile scored 85, where the animated heroes still cost layout shift.

A grade can miss the things a real visitor actually hits. So alongside it, I checked all four software service pages at 1440, 768, 390 and 320 pixels: hero and closing calls to action aligned, no horizontal overflow on any of them. A separate audit of 126 public pages found no links or metadata still pointing at the staging site.

SEO 30/30 confirms the basics: the site is indexable and has meta descriptions. It is not a ranking, not proof of index inclusion, and not evidence that AI tools recommend the site. Security 10/10 covers HTTPS and the tool's JavaScript library checks, not a security audit. And I am not claiming traffic, enquiries or conversion changed. Nothing here measures that.

The report left two items: responsive image sizing and CSS minification. The next pass serves correctly sized images and compact production stylesheets without touching the approved design, image proportions or card layouts. Reserving space for the animated heroes, to remove the mobile layout shift, is on the same list. None of that is in the numbers above.
