Principals: The Maximalist
How Harsha Subasinghe Built a Travel Tech Empire — Then Refused to Stop
A Sri Lankan engineer with a PhD in artificial intelligence founded one of the world’s largest travel booking platforms — then decided that was not nearly enough.

Most of the founders in this series share a trait: discipline. They chose a problem, built a company around it, and held that line for decades. Harsha Subasinghe shares their ambition but not their restraint. He built a global travel technology platform, then used the same campus and the same engineering culture to launch an electric supercar, a national EV charging network, an AI-powered agriculture system, and a smart classroom platform. The word for this is either visionary or chaotic. Twenty-five years of evidence suggests the former.
London, Then Home
Subasinghe’s path to founding a technology company ran through London. He earned a bachelor’s degree in electrical and electronics computing from Middlesex University, a master’s in information technology from City University, and a PhD in artificial intelligence and software agents from the same institution. Before returning to Sri Lanka, he worked as a senior software engineer and project manager for a specialist travel IT solutions provider — the domain expertise that would define his first company.
In 1999, he co-founded CodeGen International with Bharat Patel, a UK travel industry executive, and his brother Kusal Subasinghe, a solicitor who would run Colombo operations. The company obtained Board of Investment status in 2001 and began building what would become TravelBox.
The Platform
TravelBox, launched in 2003, is an end-to-end travel technology platform — booking, fulfilment, dynamic packaging, and back-office automation for tour operators, airlines, cruise companies, and hotel chains. The client list reads like a catalogue of global travel: Virgin Holidays, for whom CodeGen was the engineering partner for over a decade. Kuoni. Flight Centre. Tour America. The platform is deployed across more than twenty countries on five continents.
What distinguishes CodeGen from the outsourcing firms that dominate Sri Lanka’s technology exports is ownership. TravelBox is CodeGen’s product, not a client’s. The intellectual property, the roadmap, and the revenue sit in Colombo. At over five hundred engineers — some accounts cite six hundred — the company is one of Sri Lanka’s largest technology employers, and its engineering centre at TRACE Expert City is one of the most substantial technology operations on the island.
In November 2025, CodeGen became the first enterprise travel platform to make all operations available through Model Context Protocols — a technical milestone that placed a Colombo-built platform at the frontier of AI integration in travel technology.
The Everything Else
In 2013, Subasinghe diversified — though “diversified” may be insufficient for what followed.
Vega Innovations, co-founded with Dr Beshan Kulapala, produced the Vega EVX — Sri Lanka’s and South Asia’s first fully electric supercar. The vehicle was scheduled for its global debut at the Geneva International Motor Show in March 2020 — the car already on site, shipped from Colombo by Maersk. When the show was cancelled days before opening due to COVID-19, Vega unveiled the EVX through a virtual press conference: dual-motor all-wheel drive, 804 horsepower, zero to one hundred kilometres per hour in 3.1 seconds, a handmade carbon fibre body, and all automotive electronics — including liquid-cooled motor controllers and lithium-ion battery packs — designed and manufactured in-house in Sri Lanka. The Department of Motor Traffic subsequently approved the Vega for road use.
Alongside the supercar came ChargeNET, a fully owned subsidiary operating Sri Lanka’s first EV charging network — over eighty stations, five thousand users, a cloud-based management platform. Then AiGROW, applying AI, IoT, and mechatronics to hydroponics and vertical agriculture. Then Cloud Smart School, a learning management system for remote education. Then Ram Studios and Qube Studio for content production. The group now encompasses nearly a dozen brands operating from the same Colombo base.
The Pattern
The breadth invites scepticism. Founders who spread across too many verticals tend to underperform in all of them. But Subasinghe’s model is not a founder chasing opportunities — it is a technology platform generating spin-offs. The AI and engineering capabilities built for TravelBox became the foundation for autonomous vehicle systems, spectral analysis, and agricultural automation. The manufacturing discipline required for an electric supercar fed back into the precision engineering of the core software business.
Whether every venture succeeds is, at this point, an open question. The electric vehicle and agriculture initiatives are early-stage by any measure. But CodeGen itself — profitable, export-oriented, IP-owning, operating at global standard for a quarter-century — is not speculative. It is one of the clearest examples of a Sri Lankan technology company that built a product, retained the value, and chose to remain in Colombo.
Subasinghe has served on the Board of Investment of Sri Lanka — a recognition of what CodeGen represents beyond its own revenues. He has been honoured as South East Asian Entrepreneur of the Year and by the President of Sri Lanka. But the more telling metric may be simpler: five hundred engineers, working on proprietary products, from a campus in Maradana. In an ecosystem still graduating from services to ownership, that is the proof of concept.
