Circular Accelerator

Accelerator Details

The built environment and construction sector needs to transition to net-zero carbon.

The ultimate goal of this accelerator programme is to cut carbon emissions in this sector by helping SMEs and start-ups bring their solution to market faster, solving real world problems.

During our six-month programme, participants can expect to engage with our first-rate network of international partners, from the UN to corporate partners who need net-zero solutions, to investors (venture, private equity and debt) and alumni.

We provide commercial and strategic support combined with tailor-made accelerator programme that is climate impact focused.

The programme is a combination of workshops, coaching and learning from your peers. It is a proven model that has supported many companies.

Accelerator Programme Stages

Evaluation Process Stage 1

The evaluation process comprises of two phases:

  1. Reading Jury: an assessment of your start-up documentation
  2. Video Pitch: only shortlisted startups will be invited to share a pre-recorded 5-min video pitch via a private link that will be assessed by our jury members.

Between 15 to 20 companies may be selected to participate in Stage 1.

Stage 1: Business Fundamentals

Help entrepreneurs translate climate aligned innovations  into viable, scalable businesses/ business lines. Focus on your customer and how to get your product into their hands. Which niche are you serving? Which problem are you solving? Figure out how to make money and scale up your business using a solid financial model. Stage 1 will give you a clear vision of creating the highest value with limited resources.


At the end of this acceleration stage, we will have up to 15-20 start-ups with the following characteristics:


Fundamental topics include:

Evaluation Process Stage 2

After an interim commercial evaluation, based upon a video pitch with clear outputs up to 10 companies will be invited to participate in the Stage 2.

Stage 2: Business Validation, Traction & Investment Ready

Help SMEs/ start-ups translate business plans into concrete value propositions. Get out there and validate your business assumptions by talking to potential customers. We provide you with the skills and tools you need to conduct good interviews, to see through all the false positives and to build your business on real insights. After validation, you’ll be better able to choose your markets and grow by addressing real customer needs.  By validating your core value proposition, it will help your business attract capital to scale and grow.


At the end of this accelerator stage, we will have 10 start-ups with the following characteristics:


Stage 2 topics include:

Low carbon and green design: green building designs that reduce the environmental/ carbon footprint of a building/ infrastructure, support the disassembly of the building/ infrastructure for reuse at the end of its life or support building adaptation over its life.
Circular materials: building materials from renewable resources (e.g., bio-based) or recycled materials, or solutions to support material recycling and upcycling (materials and process) or software/ platforms to help close the material reuse loop.
Modern Methods of Construction: approaches can include 3D printing, and off-site construction/ pre-fabrication. Modern construction methods can also include “designing out” materials with a high carbon footprint.
Energy systems: systems that increase the energy efficiency of all building/ infrastructure operations, and building-integrated or stand-alone renewable energy technologies and storage systems.
Maintenance systems: support operational efficiencies for a building/ construction project and potentially extend the life of the building, e.g., predictive maintenance, drone technology, etc.
Biodiversity: recognising the relationship between nature and the built environment, we want to support innovations supporting biodiversity across its value chain, e.g., it is a source of material to the sector, and developments can disturb habitats and wildlife.
Transport and equipment: alternatives to transport/ equipment powered from non-renewable sources.
Monitoring and reporting: use of software/ tech to support efficient use of resources (e.g. energy) and to monitor, control and report
