Building LumiAIres

How Dr Giulia Marcucci Turned Light-Based AI Into Venture Momentum

From Research to Venture

LumiAIres Ltd is a deep tech company building neuromorphic photonic processors designed to make AI computing dramatically more energy efficient. At the centre of the story is Dr Giulia Marcucci, who spent nine years across academia and startups developing the core technology before taking the leap into company building. The venture emerged from a clear commercialisation path: a way to build neural networks made of light and create a processor capable of running AI with far lower energy demands than conventional systems. The technology can reduce the compute needed for certain tasks from billions of parameters to hundreds, with the chip solving problems at roughly 10 to 40 watts. Support through Techscaler, delivered by CodeBase, helped Giulia move from researcher mindset to founder execution, widening access to community, mentorship, investor conversations, and international perspective.

The game that really created the transition from my mindset of an academic researcher before to the mindset of an entrepreneur was in Techscaler Silicon Valley, frankly.

Turning Light Into Compute

LumiAIres grew out of years of technical research into how neural networks could be built using light rather than relying solely on conventional electronic computation. Giulia had spent nine years in academia and startup environments developing the underlying science before recognising there was a clear route to commercialisation. The company was then built with her co-founder, Jeremy Delhommeau, whose manufacturing and programming background helped turn the technology into a product direction grounded in real-world use. At its core, the company is addressing a pressing infrastructure challenge: the rising energy cost of AI. Its processors are designed to reduce computation, improve efficiency, and enable secure, sovereign deployment in environments where power, cooling, and resilience matter.

Deep Tech Ambition Needed Structure

Before deeper engagement with CodeBase and Techscaler, LumiAIres was navigating a familiar deep tech gap. The technical ambition was strong, but the path from research to venture building was harder to access. Coming out of academia without forming a spin-out created friction, especially because many programmes aimed at deep tech were geared toward academics or newly graduated PhDs. Hardware also brought very different economics from software. Building a lab alone was cited as costing more than £1 million, while the company expected a product timeline of around three years. Alongside funding constraints came the challenge of credibility, with Giulia describing the need to keep stepping into rooms despite anxiety, scepticism, and limited trust from others. Techscaler helped reduce that isolation and add structure.

  • Transitioning from academia without spin-out pathways tailored to their stage and model
  • Building hardware with long development cycles, high upfront costs, and funding pressure
  • Establishing founder credibility while navigating isolation, scepticism, and limited early support

A Shift in Mindset

CodeBase first entered the picture through a breakfast event that introduced Giulia to the Startup First Steps programme, now Catalyst. That early contact mattered. The programme helped with the software and business side of the venture, while also providing connection to a founder community outside academia. Standard techniques such as the five Ws and the mother test helped sharpen customer conversations and market understanding. From there, Techscaler’s Silicon Valley programme became a turning point, a major game changer that shifted Giulia’s mindset from academic researcher to entrepreneur through full immersion, higher-level conversations, and exposure to a more ambitious operating environment. Along with this engagement with CodeBase’s Greentech programme as a speaker opened different doors into sufficient enterprises and built valuable connections with new green data centers like DelaVida.

From Access to Execution

The value of the programme extended beyond exposure. Meaningful support from advisor Liza Sutherland, alongside deep tech specialist Alan Clark, in helping refine market validation and qualify opportunities at an early stage. Techscaler also widened the company’s network, from founder peers and investor conversations in Silicon Valley to Greentech speaker engagements and a pitching event at Mindspace. Just as important was the sense of fit. Giulia reportedly felt immediately at home in Silicon Valley’s technically oriented environment, while also returning with sharper conviction about solving AI’s energy problem. CodeBase’s programmes did not replace founder resilience, but they gave it direction, community, and practical momentum.

What Ecosystem Support Makes Possible

For LumiAIres, support from CodeBase and Techscaler came at a point where technical excellence alone was not enough. The founder needed founder community, practical frameworks, market validation, and access to rooms that could accelerate belief as much as opportunity. This case shows the role tailored ecosystem support can play in helping deep tech ventures move from promising research to credible company building. For founders, it is a reminder that the right programme can sharpen direction. For the wider ecosystem, it shows what becomes possible when support is ambitious, founder-led, and built around real barriers to scale.

You just step into the room [rooms with investors, ecosystem partners, and industry stakeholders] every time when they like you, when they don't like you, you just step into the room and you continue to step into the room.
