Allia Impact Accelerator

Female founder pitching at Allia Impact Accelerator demo day

6 months of intensive workshops and support to take you to the next level in your impact journey

Who is this programme for?

The Allia Impact Accelerator is for late pre-seed or seed impact start-ups that aim to address the most pressing local and global challenges. You will have demonstrated traction and are now looking to develop and scale up your business. Founders must be living/operating in London, Cambridge and Peterborough. 

We will accept participants outside of these locations if you are willing to attend the in-person sessions in London.

Applications aren’t currently open for this programme, but register your interest now and we will contact you when the next programme is scheduled to run.

The offer

We’re dedicated to helping founders like you create solutions that respond to long standing economic and social issues, that align with the UN Sustainable Development Goals. If this is you, we can offer 6 months dedicated support with:

Demo Day

To conclude our Impact Accelerator programme, our cohort will showcase their ventures through our Demo Day in November 2023. Our ventures that successfully qualify for the Demo Day through a series of pitch practices will be coming together in London, to pitch to an audience of impact investors (angels, VCs, family offices), advisors, start-up founders and stakeholders in the impact space. 

The Demo Day is a culminating exercise for all our founders to invite the Allia community to join them in their start-up journey.  

The Allia team has been really brilliant from start-to-finish. They always made time for us and made exceptional listeners and sounding boards. They regularly surprised us with thoughtful introductions out of the blue – to highly relevant mentors, industry leaders and investors.”

Sean Donnelly. Founder of Ripples

We are intimately familiar with the challenges that both traditional start-ups and impact businesses face and have built a programme with you in mind. Our team and network of expert coaches and mentors are committed to accelerating your business forward to address some of society’s greatest challenges.

You must be able to commit to attending 75% (~20) of our workshops/sessions throughout the six-month programme. Sessions will vary depending on topic but will on average occur twice per month. Dates for all workshops will be provided as early as possible, and additional 1-1 mentoring meetings (running throughout) can be virtual and scheduled at your convenience. You must be able to share metrics around your progress during and after the programme for at least one calendar year.

Sessions will likely be held on Tuesdays between 10am-12pm.

We are dedicated to supporting founders and business owners amplify their impact. It’s what we do. Whether it be a local social entrepreneur or the next tech for good solution. Every venture’s work we support, goes towards our sponsors objectives of supporting a specific community or issue. Our partners are keen to see you make a difference in the world and have dedicated their resources to building out the various Allia programmes.
We look for businesses that are late pre-seed or seed stage, have demonstrated traction. They should be addressing local and global challenges, and looking to make an impact on people, place or planet. Maybe you’re tackling climate change, improving health and wellbeing, or addressing food waste. If your business is making positive change, then we’d love to hear from you.
