Six courses. Four tiers. One ledger.
The EV + hybrid trade is growing 10%+ a year and is short the hands to service it. HHN puts the entire pipeline — classes, labs, certification, and the job board — under one roof, and writes every credential to a portable ledger that follows the tech for life.
Career Ladder
Every enrollee lands on a tier the day they finish their first course. New certs stack — they don't reset you. A mobile detailer with HHN-110 today can be running an L3 recon lab in 12 months without changing employers, schools, or transcripts.
Apply on HHN
No third-party gatekeepers. Pick a track. The system maps your nearest L3/L4 lab for hands-on hours.
Tier is assigned at enrollment
Every course you pass advances your tier on the Hub Ledger. Your record is portable across every shop on the network.
Certify the skill, not the seat-time
Written + hands-on at a Hub Certified lab. No expired certs hiding on a resume — the ledger is live.
Auto-listed to the job board
Your tier + endorsements appear to every shop on the network the day you finish. Apply with one tap.
Tech Workforce
The EV + hybrid market is forecast to grow double-digits every year through 2030. The trade is already short 3x the certified techs it needs. HHN closes the gap — classes, certs, and the job board all live under one roof.

Certify the skill, not the seat-time

Auto-listed to the job board
Certified the day you finish. Shops on the network see open techs by tier, location, and endorsement — no resume roulette.
Every job feeds the data
Work done by HHN-certified techs streams clean diagnostics back into Oracle. The workforce literally builds the dataset that funds the next class.
// The compounding effect
Every certified tech on HHN is a sensor. Every sensor sharpens Oracle. Sharper Oracle wins more OEM, insurer, and fleet contracts. Those contracts fund more scholarships, more lab seats, more L3/L4 nodes — which certify more techs. Labs, dealers, indie shops, mobile ops, and university R&D all plug into the same ledger. No more siloed knowledge. No more wasted talent. The industry grows 10%+ a year — HHN makes sure the workforce grows with it, certified and safe.
