Anchor case study · 3-year engagement

WorldSpa — premium spa group, embedded across five service lines.

Our longest-running engagement and the clearest demonstration of the engineering firm model: SEO foundation built first, evolved into content articles, AI video pipeline, custom Stripe + dynamic pricing integration, and ongoing engineering as the operation grew. Same team, three years, continuous evolution.

Five service lines, evolved over three years.

The engagement started small (technical SEO + 4 articles per month) and grew as the relationship matured. Each service line was added when WorldSpa needed it, not pitched preemptively.

Year 1 · Foundation

SEO & Content

Technical SEO audit + remediation. Content strategy + monthly long-form articles in the brand voice. Search Console monitoring. The slow-compounding work that pays off year 2 and after.

Year 1–2 · Custom integration

Software Development

Custom Stripe integration with vendor API for dynamic pricing across 30+ services. Admin dashboard for ops team. Webhook reliability + idempotent retries. Production-grade billing infrastructure.

Year 2 · Content scale

Creative Production

AI video pipeline (Anton-style narrated reels) for Instagram + TikTok cadence. 30+ reels per quarter from monthly photo shoots. Brand-consistent across volume runs.

Year 2–3 · Search expansion

SEO + GEO

Traditional SEO maintained + GEO experiments for AI search surfaces (ChatGPT, Perplexity). Google Ads + Meta Ads attribution wired to a single dashboard.

All 3 years

Operations Partner

On-call engineering, dev sprint capacity, fractional CTO advisory. The base of the relationship — every other service line plugs into this team.

Year 3 · AI capability

AI Infrastructure (in development)

Custom AI agent for ops team — reads vendor emails, surfaces booking anomalies, drafts responses. Built on the same SAE4U Agent platform we open sourced. Currently in pilot.

WorldSpa is the proof that the embedded model works.

Three years of continuous engagement at a single client demonstrates what most agency engagements never reach: real institutional memory, evolutionary work that builds on itself, and a team that defends the system as it scales. WorldSpa is grandfathered on legacy a-la-carte pricing — they're our anchor client, not our pricing testbed. New engagements enter at the $10–15K/mo retainer model documented on the homepage.
