Stop losing customers to slow page loads.
Three weeks. We pick the page that matters most. We move the needle on LCP, CLS, and INP. The conversion lift is downstream.
- Core Web Vitals into the green zone
- Real RUM data, not just lab scores
- Conversion lift you can attribute
- Knowledge transfer so it stays fast
What you actually get.
Critical-path audit
We profile your most-trafficked page on real-device throttling and tell you exactly what's costing you milliseconds.
JS budget surgery
The 280KB dropdown nobody noticed. The duplicated lodash. The polyfill for browsers that haven't existed in five years.
Streaming & RSC migration
Move blocking server work into Suspense boundaries. Show the LCP element first, fill in the rest after.
Image, font, third-party tag pass
AVIF/WebP, font subsetting, third-party tag triage. The boring high-impact work nobody does.
Real numbers from past engagements
A predictable, founder-friendly engagement.
- 01
Pick one page, one number
We pick the highest-leverage page and the single metric to move. Everything is downstream.

Profile, fix, re-measure
Three weeks of focused work. Daily Slack updates, weekly RUM check-ins.
- 03
Knowledge transfer
Your team learns the playbook so the next page you ship is fast by default.
- 04
30-day check-in
We come back 30 days later to confirm the gains held in production.
Frequently asked questions
No. We promise the engineering metric. Conversion is downstream of a hundred things — promising it would be marketing, not engineering.
