About Vertex CTO Advisory
25+ Years in Technology Leadership.
From Wall Street trading floors to global IT operations across three continents — the experience behind Vertex CTO Advisory was built in environments where technology decisions carry real consequences.
Thomas Cloud — Founder, Fractional CTO & Technology Operating Partner
Built on the Inside, Advising From the Outside
Vertex CTO Advisory was founded by Thomas Cloud, a technology executive with 25+ years in technology — spanning IT strategy, infrastructure, cybersecurity, and vendor operations for organizations ranging from global investment banks to growing mid-market companies.
That experience was not built in a classroom or a consulting firm. It was built running trading floor technology through 9/11 in lower Manhattan, leading desktop and infrastructure operations across four Asia-Pacific countries, integrating an acquired boutique investment bank in Australia, and keeping regional operations running through the bankruptcy of Lehman Brothers and the Nomura acquisition that followed.
After nearly 13 years in investment banking technology at Lehman Brothers and Nomura International, Thomas transitioned to the managed services industry — first founding and operating 48 Technologies in Dallas–Fort Worth, then taking on a Director of Technology role at a second MSP to lead an operational turnaround. In 2024, he founded Vertex CTO Advisory to formalize the technology advisory work he had been doing for private equity firms and their portfolio companies.
We've sat in the seat your vendors sit in. We've managed the teams your leadership relies on. And we've made the decisions your business needs someone to own.
That operator's lens — built from managing infrastructure, security, vendor contracts, service delivery, and cost discipline at the MSP level — is what PE firms and mid-market companies need most. It means we understand what actually breaks after a deal closes, where vendor sprawl creates hidden cost, and how to stabilize technology operations quickly without disrupting growth.
Career Highlights
Where the Experience Was Built
Founder & Principal
Vertex CTO Advisory · Dallas–Fort Worth, Texas
Founded Vertex CTO Advisory to formalize technology advisory work for private equity firms and their portfolio companies. Engagement models scoped to the actual demand of the hold period: pre-acquisition technology diligence, post-close 100-day assessment and remediation planning, fractional CTO for portfolio companies between $10M and $100M+ revenue, MSP oversight and vendor management, and exit-prep technology hardening.
Engagement footprint to date: Advisor on 5 PE transactions across 11 portfolio companies. Multi-quarter engagements, not one-off reviews. Sectors: financial services, healthcare, and manufacturing — each chosen because they map to a side of the table already sat on.
Director of Technology (Advisory Turnaround Engagement)
Managed Services Firm · Dallas–Fort Worth, Texas
Brought in by a Dallas–Fort Worth MSP to lead an operational turnaround of its technology delivery organization. Responsible for service delivery quality, technical leadership, vendor and toolchain rationalization, and rebuilding the engineering function from the inside. Engagement structured as embedded leadership rather than outside consulting — the same model Vertex now offers to PE-backed portfolio companies needing operator-level technology oversight without a full-time CTO hire.
Founder & Owner-Operator
48 Technologies · Dallas–Fort Worth, Texas
Founded and operate 48 Technologies, a managed services firm serving small and mid-market businesses across the Dallas–Fort Worth region. Direct accountability for service delivery, technical operations, security tooling, vendor relationships, P&L, and client retention. The hands-on MSP ownership directly informs how Vertex CTO Advisory evaluates and oversees technology providers on behalf of PE sponsors — the diligence work is sharper because the work being diligenced is the work we do.
Vice President — Infrastructure Manager, Asia
Nomura International · Hong Kong
Continued running regional infrastructure operations through the Lehman Brothers bankruptcy and Nomura's acquisition of Lehman's Asia-Pacific business in September 2008. Reported to the Asia regional CIO. Managed 20+ staff across four countries covering desktop support, market data, messaging, and multimedia. Managed the strategic expansion of a near-shore IT center in Shanghai. Consistently delivered regional budgets 10–15% below target.
Vice President — Desktop Support Manager, Greater China
Lehman Brothers · Hong Kong
Transferred to Hong Kong approximately six months before the Lehman bankruptcy. Responsible for run-the-bank operations across two trading floors with 400+ traders and 1,600+ users in Greater China. Accountable for desktop technology strategy, execution, and engineering across capital markets, corporate and investment banking divisions in Hong Kong, Taiwan, and Greater China — on the ground in Asia when Lehman filed for bankruptcy on September 15, 2008.
Vice President — Technology Integration Lead, Australia
Lehman Brothers · Sydney, Australia
Personally oversaw the technology integration of Grange Securities, a Sydney-based boutique investment bank acquired by Lehman Brothers in January 2007 and rebranded as Lehman Brothers Australia. Spent approximately one year on the ground in Sydney bringing the acquired entity onto Lehman's global infrastructure, desktop, and application environment — the kind of post-acquisition technology integration that PE sponsors now hire Vertex to plan and execute.
Assistant Vice President — Desktop Engineering Manager, Asia Pacific
Lehman Brothers · Tokyo, Japan
Responsible for all desktop engineering technology across Lehman Brothers Asia. Led change control and IT governance procedures. Member of Global Change Management Control. Built a highly skilled team in a rapid-growth environment and managed key vendor contracts including selection, SLA negotiation, and outsourced relationships.
Assistant Vice President — Team Lead, Desktop Support Engineering
Lehman Brothers · New York
Team lead for trading floor desktop support at Lehman Brothers global headquarters. Supported 1,000+ front office traders and research users. In the week after September 11, 2001, helped rebuild two trading floors. Built key relationships with regional CAOs, senior management of Capital Markets, and back-office functional heads across Finance, Operations, and Compliance.
What This Means for Clients
Four Countries of Operating Experience
Trading floor and infrastructure technology leadership across New York, Tokyo, Sydney, and Hong Kong — with regional responsibility extending into Taiwan, Greater China, and Shanghai.
Owner, Operator, Buyer, Diligencer
VP at Lehman and Nomura. MSP owner-operator since 2012. PE technology advisor since 2024. Every side of the vendor table, in seat, with budget authority — not from a conference panel.
Budget Discipline
A track record of delivering regional technology budgets 10–15% below target — without cutting corners on capability or security. The discipline transferred from a $TN balance-sheet bank to mid-market portfolio companies one-to-one.
Crisis-Tested
Rebuilt trading floors after 9/11. Integrated an acquired bank in Sydney. Kept regional operations running through the Lehman bankruptcy and the Nomura acquisition. The kind of resilience portfolio companies need in the first 100 days only comes from being in the room when it mattered.
If you're evaluating technology leadership for a portfolio company, the first conversation is free.
Pre-acquisition diligence, post-close stabilization, fractional CTO for the hold period, or MSP oversight on behalf of a sponsor — if it's the kind of work this page describes, let's talk.
