Astra — software that actually works.
AstraEngage is my flagship AI-native platform — conceived, architected, coded, and shipped 100% by me, with no outside contractors or employees. With 10+ modules — a full CRM plus pipeline, proposals & e-sign, projects, portals, and customer service — it's more than any CRM. It's a full business operating system. It brings genuinely new ways to use AI to solve software headaches decades in the making — building software the way it always should have worked, and hardened and improved daily. AstraEngage is just the first major buildout, with more tools and solutions in development.
Built on Astra Cloud with defense-in-depth security — AES-256-GCM per-tenant encryption, SOC 2 Type II audited infrastructure, and HIPAA-ready dedicated silos.
An old dog who learns the new tricks — by building them himself.
George didn't just adopt AI — he embedded himself in building Astra so he'd be fully hands-on: not merely using AI software, but architecting and developing it. That lived, in-the-code experience is exactly what he brings to clients — guiding AI use and policy, informed decisions, enablement, implementation, integration, and execution.
But make no mistake — George is not all tech. He's a hardened, true businessman who has founded and built real companies: THUMBTECHS, Mebuis, MebuisWorks, and 1908 Builders. Technology is a key part of the story, but it takes a strategic, smart, experienced, and competent operator to build companies like these — and to help build the many client companies he's partnered with over the last 10+ years.
He's the businessman who doesn't just understand technology — he has made it for decades, from his patented FileKey system to Astra today. George gets the business: the efficiency, the lean processes, the profit, the ROI. But he's also the technical mind who understands how systems — AI and non-AI alike — actually work, and how they should be integrated, made effective, and executed in the real business world.
Architecting the right systems — and getting them to work together so seamlessly that employees and users actually adopt them — is what makes a business run better. That rare combination of operator and builder is why companies turn to Mebuis and MebuisWorks as their exclusive resource to make their business soar in today's world.
The businessman
Founder and builder of THUMBTECHS, Mebuis, MebuisWorks, and 1908 Builders — real companies, real P&L ownership. Three decades of growth behind every recommendation.
The technologist
From a U.S.-patented identifier system to a self-built AI operating system — he understands how systems truly work, not just how to buy them.
The architect
Integrating the right systems — AI and non-AI — so they work together and people actually adopt them, so your business runs better.
