Applications are now closed - but you can still register your interest below.

Who is this programme for?

The Allia Impact Accelerator is for late pre-seed or seed impact UK-based start-ups.   

Start-ups will have an MVP, should be able to demonstrate traction, and are now looking to develop the next stage of growth in their business. Ideally, founders will be able to travel to London occasionally to benefit from in-person interactions – however, we recognise that not all participants may be able to travel, and if this is the case, please share details in the application form.

We understand that in person interactions may not be ideal for everyone so please understand that we will aim to be flexible for all taking part. Above all, we prioritise genuine and authentic engagement in the programme and with our team, and want to welcome everyone who thinks they will benefit from participation in the programme.

We are now closed to applications but you are welcome to register your interest in our future Impact Accelerator Programmes.

The offer

We’re dedicated to helping founders for the next 5 months who are ready to take their start-ups to the next level. If this is you, join our Impact Accelerator programme and you will have access to:  

Networking event

Demo Day

To conclude our Impact Accelerator programme, our cohort will showcase their ventures through our Demo Day in June 2024. 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.  

DO. THIS. Best Accelerator on the planet.

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.
Once you have completed the application form and we have reviewed your business, we’ll invite shortlisted candidates to an interview. Shortly after your interview, we’ll let you know whether your application has been successful.

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.

Workshops are usually on Tuesdays. In-person sessions will be held at least once a month at our London office (Queen Mary Enterprise Zone). Most of the sessions are being held online or in hybrid format. 

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.
