Speed, as a feature.

Core Web Vitals remediation, frontend and backend latency tuning, edge architecture and performance budgets enforced in CI. Speed treated as a feature with a launch date.

§ 01The problem

The problem we solve

Performance is the highest-leverage UX improvement most companies ignore. A 1-second LCP improvement moves conversion, retention, and search rankings. But it's invisible to anyone not measuring, and it regresses silently the moment you stop. We make it measurable, gateable in CI, and improvable.

§ 02Capabilities

What we ship

  • 01Core Web Vitals audit with real-user monitoring
  • 02LCP, INP, CLS remediation
  • 03Bundle analysis and code splitting
  • 04Image and font optimization done correctly
  • 05Edge rendering with Cloudflare, Vercel Edge, Fastly
  • 06Database query optimization and N+1 elimination
  • 07API latency reduction with caching, query design, async
  • 08Performance budgets enforced in CI
  • 09Synthetic monitoring and regression alerting
  • 10Mobile performance: low-end devices, slow networks

  • Companies whose mobile experience is hurting on real devices
§ 06Process

How an engagement runs

  1. 01

    Audit

    Real-user data, synthetic tests, profiling. The work is identifying which 20% of fixes produce 80% of the wins.

  2. 02

    Quick wins

    Image, font, render-blocking JS, server-rendering — the changes that move the needle in a week.

  3. 03

    Structural improvements

    Bundle architecture, edge migration, caching, query optimization.

  4. 04

    Defend

    Performance budgets in CI so improvements don't regress as features ship.

§ 07Engagement

How to engage

01

Performance Audit

1 — 2 weeks

Real-user audit with prioritized recommendations.

02

Performance Program

6 — 12 weeks

Audit + implementation + CI gates so improvements stick.

03

Performance Retainer

Ongoing

Quarterly tuning as the product grows.

§ 08Common questions

Frequently asked.

01Can you make our site as fast as Vercel's?

Often, yes. We've taken sites from Lighthouse scores in the 20s into the 90s. Whether yours can get there depends on the constraints — we'll measure and tell you what's realistic.

02Will improvements stick after you leave?

We enforce performance budgets in CI. The site can't regress past the budget without your team explicitly choosing to.

Have a problem worth solving well?

Tell us the outcome you want. We'll tell you what it takes — honestly, within a week, in writing.
