San Diego · Tijuana — est. 2000
CST Consulting pairs 25 years of executive experience with hands-on AI engineering — strategy, operations, and automation delivered as working systems, not slide decks.
What we do
Most consultancies stop at the recommendation. We staff both sides of the work: the judgment to choose the right move, and the engineering to build it.
Practice 01 — Advisory
Led by Hector Campa — an executive who has built and run companies on both sides of the US–Mexico border for 25 years, and teaches in a doctoral business program.
Practice 02 — Systems
Led by Hector Campa Jr. — an AI automation architect and full-stack engineer who builds enterprise-grade systems, not template integrations.
Results
AI voice receptionist and custom CRM for a Dallas dental practice — 24/7 coverage, automated intake, reminders, and no-show follow-up.
Voice agents · Healthcare
A RAG agent that turned a law firm’s archive into an instant research tool — months of manual review collapsed into a query.
Document AI · Legal
End-to-end automation for a med-spa: from ad click to booked appointment with no human in the loop, saving $3–4K monthly.
Automation · Med-spa
Twenty-five years guiding companies through product development, sourcing, and operations across 100+ client engagements.
Advisory · Track record
Who you work with
A father and son who cover the full distance between the boardroom and the codebase.

The builder
Founding Partner — AI & Automation
AI automation architect and full-stack engineer with a background in finance and algorithmic trading. Lead developer for two US-based tech companies, with a SaaS exit under his belt. He engineers the systems this firm recommends — CRMs, voice agents, and automation pipelines that clients own outright.
LinkedIn ↗Why us
We have run the kinds of companies we advise — payroll, production, and P&L — for 25 years. The advice comes from experience, not frameworks.
Every system we recommend is engineered by us. No subcontractors, no hand-offs, no gap between the plan and the product.
You approve a price before work starts, and it does not change. The incentive is finishing well, not billing long.
Bilingual and binational — San Diego and Tijuana. We work in English and Spanish, in US and Mexican business cultures alike.
How it works
Step 01
A two-minute form: what your business does and where it hurts. We review every inquiry personally before anything else happens.
Step 02
A free 30-minute conversation — and because we did our homework first, it starts at the problem, not the introductions.
Step 03
You get a concrete proposal with scope, timeline, and one fixed price. No hourly meters, no surprises.
Step 04
Advisory produces decisions you can act on; systems end as working software in production. Optionally, we stay on to manage and improve it — you own everything either way.

Start with a two-minute form. We do our homework on your situation first — so the call that follows is about answers, not introductions.
