What are the eligibility criteria? 
To be early-stage; under c.£3M in equity funding and £3M sales and to fit into one of the tracks mentioned above.

Do I need to incorporate in UK? 
Your company doesn’t have to be incorporated; however, you should have a presence in the UK or be able to demonstrate how the UK is a target market for your technology and your startup.

Will I have to come to Switzerland to follow the acceleration programme? 
Yes, you should be prepared to travel for up to 10 days over 4 months, to meet corporate partners, mentors, investors, etc. We’ve gathered together as many in-person events as possible so you don’t have to travel back and forth. These events are mandatory to ensure you benefit from this program.

Is the programme free?
Yes. MassChallenge does not charge a fee & no equity is taken. And you have the opportunity to win £10k in prize money as the best startup in the UK programme, and also to compete for up to 1M CHF from the Swiss Acceleration program. All cash prizes are no-strings-attached and non-dilutive. 

How much time to give per week? 
Between 1 and 2 days depending on the week and your objectives. 

Can anyone from my Team attend the in-person events? 

I'm not early-stage anymore. 
We think that it's not worth applying if you're significantly over £3Mn capital raised and £3Mn sales.

What's the difference between MassChallenge Switzerland and MassChallenge UK in this programme? 
MassChallenge UK is scaling operations in the UK, startups will attend and organising the physical events in the UK for the startups in the UK programme. MassChallenge Switzerland is organising physical activities in Switzerland and online that the startups in the UK programme will participate in.

How do I win the cash prize money? 
Startups will be judged in October on the basis of their pitch to an independent jury of experts. The highest-rated startup in the UK programme will win £10,000, no strings attached. The UK startups can compete with MassChallenge Switzerland's startups to win up to 1m CHF based on the quality of their pitch to an independent jury of experts.  

Will there be physical events in London?
