In the next edition of our meet the founder series, we meet GreenFlip – a company with big ambitions for retrofit. Its founders – Amandeep Singh Kalra and Thomas Quiroga – tell us more about their journey so far, and what they hope to achieve during the Geovation Scotland accelerator programme. 

Tell us about your startup – what problem are you solving and why does it matter? 

GreenFlip exists to make retrofitting homes investable. Millions of homes across the UK are still cold, energy inefficient and expensive to run. Decarbonisation is stuck at just 1% a year, and that rate needs to triple across Europe. The challenge is that investors and housing providers find retrofit slow, costly and fragmented. GreenFlip’s AI solves this by instantly analysing homes, identifying those with the highest retrofit potential, and packaging them into investable portfolios. This gives asset managers, property funds and housing associations the clarity to act at scale – cutting risk, achieving net zero targets and delivering “zero-bill power stations” that lower costs for residents, reduce carbon and increase ROI. 

Tell us more about the team at GreenFlip and your background? 

GreenFlip was founded by Amandeep Singh Kalra and Thomas Quiroga who met through Carbon13 – a venture builder for climate tech entrepreneurs.  

Amandeep is an architect with over a decade’s experience in housing. In his previous role, he led a team that supported a £1.1bn development programme and he currently serves as a Non-Executive Director for two housing associations.  

Thomas has 15 years of experience leading software and product. He co-founded Rooser – a tech company that provided a global online marketplace for seafood trading – and has retrofitted his own home. 

 Together they bring housing expertise, property investment knowledge and proven tech-scaling experience, with a shared passion for solving retrofit – the process of making energy efficiency improvements to an existing building by adding or upgrading its materials, products, or tech. 

What inspired you to start this company? Was there a personal story behind it? 

The inspiration came from personal experiences. Amandeep grew up in a damp council estate where his mum’s asthma was made worse by poor housing. Later, as an architect, he worked on a 29,000-home estate where he saw all the different pieces of the puzzle that could make the homes more energy efficient – but felt powerless to put them together. Thomas retrofitted his own leaky house to make it healthier for his newborn son but found it impossible to persuade neighbours to do the same – even though the benefits were obvious. Both recognised the real barrier to retrofitting wasn’t technology – it was making the economics work and helping people to put the pieces together. GreenFlip was built to solve exactly that. 

What are your goals during the accelerator programme? 

The GreenFlip platform identifies the best energy upgrade opportunities to drive value, savings and carbon reduction within homes. During the accelerator programme, the goals are to integrate Ordnance Survey, Registers of Scotland and Land Registry data into the platform, test models on Scottish housing stock, and build partnerships with housing associations, local authorities and investors. The focus is to launch a Minimum Viable Product (MVP) with pilot customers and convert those pilots into the first paying customers. There is also the ambition to grow the team further – particularly in Scotland – and raise the pre-seed round to take the next step. 

What’s been your proudest moment so far as founders? 

Two moments stand out. First, securing three Letters of Intent with investors and housing partners covering more than 400 homes – proof that appetite exists if retrofit can be made investable. Secondly, hiring the very first team member who is mission-aligned and driven by the same goals. 

How can people support you? 

GreenFlip is looking for asset managers and property investment funds to pilot the platform. The team is also hiring, with roles for machine learning engineers and a founder’s associate. A pre-seed round will be opening soon to support the next stage of growth. Anyone who shares the vision of turning 1 million homes into power stations can get in touch at hello@greenflip.homes
