One company. Three functions.
NextGen Consulting Services FZ-LLC advises and builds. Engineering & regulatory advisory and business development sell the judgement — a senior opinion that carries an expert's signature. SpecSell, our software platform, sells the system — a deliverable that survives the mission. Consulting sells the judgement; SpecSell sells the system.
Dr. Marwan Chamoun
Franco-Lebanese HVAC&R engineer, PhD (INSA Lyon). R&D years at Carrier — three industrial inventions in refrigeration — then international engineering at Danfoss, then founder and operator of businesses across Europe and the Middle East: hospitality, consulting, software.
SpecSell is where that double life converges — an engineer who has also carried the sales bag, building tools for both.
A founder-led network of senior specialists
We are a founder-led network of senior HVAC-R specialists: over 100 years of combined field practice, doctorate-level engineering, patented innovations, and delivery across the Middle East. We keep the spotlight on the work, not on individuals — the capability is the network, assembled per mission.
Engineering domains
Working practice across HVAC, refrigeration, mechanical, electrical, energy and oil & gas — the rules are modelled by people who understand the installations they govern.
Software & AI
The platform itself, and the AI-assisted engine-authoring method — verified adversarially, deterministic at runtime.
Cybersecurity
Engine custody, IP protection and client-instance isolation — security as a design habit, not an afterthought.
Design
White-label instances that look like the client's best digital product — not a bolted-on tool.
Relationships, presence, discretion
Business in the Gulf is built on trust and continuity. We work as a long-term partner — present, discreet, and straight-talking with decision-makers. A senior conversation, not a sales pitch.
