HOW IT WORKS

BUILT FOR SHOPIFY + KLAVIYO STACKS

Stop getting locked into self-serving 12-month agency retainers. We deploy a fully automated, high-converting customer retention system directly into your Klaviyo account. No long-term contracts. No slow drip-fed deliverables.

THE MARKET HAS SHIFTED. WHY ARE YOU STILL PAYING RETAINERS?

THE TRADITIONAL AGENCY TRAP

THE HOUSE LINDEN SYSTEM

RIGID 6 TO 12-MONTH CONTRACTS.

Locks you in and places all the risk on your shoulders.

NO FRONT-END CONTRACTS.

Pay an upfront flat fee for speed, leverage, and complete agility.

DRIP-FED SERVICE DELIVERY.

Automations and flows are dragged out over months to justify recurring bills.

24-HOUR DEPLOYMENT.

Your entire back-end retention system is built and fully live in 24 hours.

COMMODITIZED AI LAZINESS.

Blocky templates and generic copy erode your brand value.

HUMAN-LED PLAYBOOKS.

Klaviyo’s technical speed, shaped by strategic human copy and design.

HOSTAGE SYSTEMS.

If you fire them, the momentum stops.

COMPLETE OWNERSHIP.

Once built, we hand over 100% ownership. The system is yours to run.
