FAQs
-
We chose the name Sie because we wanted a word that represents females (our initial focus), but doesn’t exclude other groups. Our long-term vision is to extend the platform to under-represented groups in the founder and investor ecosystem, making Sie - which means so many things - apt for our objective. In German, Sie means:
“she” (nominative feminine singular),
“they” (nominative plural, no distinction between masculine and feminine),
“her” (accusative singular) for a female person (or “it” in English for a feminine thing in German),
“them” (accusative plural, no distinction between masculine and feminine).
It is also the courtesy pronoun for “you”, similar to “vous” in French.

Firstly, we don’t consider ourselves an accelerator because we do not take equity and our support only covers fundraising. We consider ourselves as Partners on your journey when fundraising. Our curriculum only covers fundraising related topics. We work with top Top Tier funds and Operators (Founders, EIRs, Experts) who share their know-how with Sie Program companies. We have facilitators from Sequioa, Seedcamp, Localglobe, Ada Ventures, Stride VC, Common Magic, Firedrop and many others. Our mentors are investors or founders who have seen it all and are here to support you on your journey. Our team is small but hands-on and truly cares about making a huge impact on your fundraise journey.

You can apply any time - we run cohorts twice a year. We review and shortlist applicants on a weekly basis during sourcing period, the sooner you apply the better.

The Sie Catalyst Program runs for 8 weeks but our founders will get lifelong access to the highly vetted Sie Founder Community as alumni once the program is complete. In this community the Sie Team as well as the alumni community continue to help you build your business and is by your side for your next fundraises ahead. We host sessions and get-togethers throughout the year to support our founders scaling their businesses.
-
We have worked hard to build the most founder-friendly model and therefore we do not take equity. However, we put a lot of work and resources into the program and therefore there is a one off fee of £1,000 (+VAT) to join the 8-week program to ensure all companies are given the opportunity to pitch to the Sie Syndicate, but no investment is guaranteed.
-
Program runs twice a year and applications are always open. During our active sourcing period we are looking through the applications on weekly basis, however, please ensure program timelines make sense for your fundraising journey.

Absolutely! We look at equitable ownership between the co-founders.
The program participant should be a female founder but we open up some sessions to your co-founder. All sessions are recorded as well, so you can always share them with your co-founder. -
We count every cheque that goes to our founders. To date we have seen 169+ cheques from Sie Investor network, either Syndicate or Catalyst. Our companies have raised £200M+ in capital to date since our launch in 2021. Our NPS score is 9.5 across the programs. We encourage you to speak to our Alumni!
