Eimantas Subacius

I build automated operational systems for calendar-heavy businesses-not websites, not slide decks. Every Onyx engagement starts with a number: no-shows recovered, commissions reclaimed, consults captured. Then we install the infrastructure that makes it real.

Patient acquisition and intake automation for med spas and dental practices
Direct booking and AI concierge layers for independent hotels
Revenue calculators and lead qualification flows wired to your CRM

Founder's manifesto

Operations are the product. Everything else is decoration.

Quantify first

No build without a dollar figure on the table.

Deploy fast

Live in weeks, not quarters. Measured from day one.

Stay boutique

One architect. Full accountability. No bloat.

Most agencies sell you a website and call it transformation. Onyx Agency installs the layer that runs your calendar, captures leads, and recovers revenue while you sleep. I built this practice because calendar-heavy businesses deserve systems-not slide decks.

I am not a freelancer with a Figma file. I am the architect who maps your no-show rate, your OTA load, and your front-desk bottlenecks into a deployable system with a number attached. If we cannot quantify the upside, we do not build.

Every engagement is partner-grade: direct access, conservative projections, and infrastructure you own. The goal is operational freedom-measured in recovered revenue, not vanity metrics.
