"Really loved the community and the way the day was planned."

"Very welcoming. Feels like a safe space for folks dipping into the start-up space."

An evening of ideas and judging, from home-cooked food at scale to data-efficient training. The room was consistent on what's different with AI: urgency and momentum.

Our first space-themed event. Participants designed their own space mission in a few hours.

In partnership with Mercuri VC, ElevenLabs, Hugging Face and Canva, we ran our 404: media not found hackathon centered around building at the intersection of media and technology.

"I loved learning the different approaches taken by different groups and learning from the variety of tech stacks used. I also loved the panel and hearing the experiences of the founders."

"It's been a lovely event to brainstorm and network! I definitely feel even more inspired to become a founder in future, knowing I have a solid foundation for that. Thank you once again for the event 💞"

"I had so much fun! I thought the set up was amazing and I really appreciated the panel in the morning. The whole experience has definitely improved my confidence and the panel made me really excited about the idea to found or co-found my own startup. I would love to attend future events!"

In partnership with Unit M at the University of Manchester, we ran a startup weekend in a hotel in Cheshire - complete with a gym, sauna, steam room, and pool - centred around "day 1 of building your startup".

"Thank you so much for organising this! I've left with such a desire to actually take action on ideas I have after seeing how much I could do in just a day! We were staying up late, waking up at 5, working non stop but it didn't feel like work at all. Also was amazing to meet so many cool women!!"

"I think the presentations were SO SO helpful because they really gave us a foundation of the basics from scratch. I think I left with a much more informed and confident mindset. I think even if business basics are available on the internet, the whole investor/vc angle is near impossible for newcomers to find. Really really loved that!"

"Very unique, loved that it emphasised actually just starting, opened my eyes to how much can be done in a small amount of time!"

In partnership with Bang & Olufsen, we ran a hackathon in Copenhagen centered around interaction with technology.

"It was ABSOLUTELY FANTASTIC to have an all woman event! Had some great meaningful conversations that wouldn't regularly pop up in mixed events! Great to get other girls inputs and experiences of the STEM industry 🧡 This was a true pleasure!"

"[My favourite part was] getting to talk with other people regarding the experience women have with technology and tracking devices."

"This event was fantastic! Great group of people from different backgrounds to meet, hear from, and work with. This event reminded me that creating things with an enthusiastic team is amazing, and that yes in fact l do know what I'm doing and I can make things."

"Loved the theme and so much fun with bad ideas and enabled us to think out of the box."

"I definitely feel less intimidated about the whole idea."

In partnership with incident.io and The Ministry, we brought together our TTB community for a day of co-working.

"Great vibes, genuine support and advice, new connections - love how it feels to be a part of the community!"

"It was so helpful and friendly in terms of discussing ideas and learning what everyone is working on. Really enjoyed that, thank you!"

"slay"

"I love the pace of this event. I love how everyone is really welcoming and ready to build something fun together. I'm more confident in building a startup now!"

"Being in a supportive environment for female founders is incredible. I felt seen and supported throughout the entire experience. There was no judgment or harmful competition - just positive vibes and a focus on building both our products and each other up. I'm so glad I took the time to attend this event."

"I feel more excited to going back to prototyping and building. I feel a lot more clear on what to focus on at my early stage. This event helped me reprioritise build above the 15 million other things expected of founders before raising pre-seed and ahead of each stage of funding."

What better way to spend a Friday afternoon than with a group of ambitious women in the world of robotics?

"This was such an informative session - I found myself inspired by all I learned."

"Really great intro to creating a successful startup and getting investors."

"I feel more confident, it helped me define the next steps to take"

"I really enjoyed the activity. My main barrier currently isn't motivation or capacity but rather perfectionism and waiting for the right idea. So having a bad idea day for focus on building confidence literally is something I would do again! Absolutely feel more informed and more likely to look into start up possibilities. Thank you so happy we were able to make this happen!"

"Truly a one-of-a-kind experience for me. I really enjoyed the challenge of going from zero to an MVP in just one day - it pushed us beyond our limits and forced us to deliver a pitch by the end. The event required a wide range of skills, from creativity and innovation to collaboration and public speaking. I think it all came together really well, and I'm incredibly grateful to have been a part of it."

"The atmosphere was great and loved how non-serious it was, made it all feel very comfortable. It was a first time for me attending such an event and it definitely has opened my mind up to possibilities!"

"It has been a lovely day and I met lots of wonderful people at the event. I'm definitely more interested in founding my own startup after the event, and feel more confident about doing so:)"

"I loved how open the event was. No coding experience required! I also love a women's space. Feels less daunting and much more comfortable!"

"At the beginning of this event I had no idea [how to code] but in less than one hour I built a website by myself. I am so glad about it because it helped to understand that I am able to work and do whatever I want with the right support"

"Such a fun way to spend the evening and I would love to do more interactive, hands on, and personal events like this in the future"

"Enjoyed how creative it is, and how working with the right people really makes things work out much better. With the right person I'm more likely to build a startup."

"10/10 Exactly what the startup and STEM climate needed! It goes a long way towards influencing sociological biases and helping like-minded people connect, especially when these like-minded people are very rare! The more extraordinary the gathering, the higher chances for unicorns ;) And community is a BIG part of the equation. Thank you! <3"

"Awesome evening, loved the low stakes fun environment of making a "bad" idea. I think that was really helpful."

"I loved that we worked on different ideas from the ones we proposed. It made it so that we weren't too set on one idea and it was fun to see the demo at the end for our concept."

"I love it! It was fun! I especially love the food and drinks served :))) And I love the photos too 🥹 Thank you for such a wonderful event!"

"Amazing event. It was really nice to get back to hands-on coding. I actually came in thinking that the time planned for hacking would not be even close to enough for an MVP. However, all groups were able to execute their projects, which was great to see. The food was great too ;) Overall, a day spent productively well."

"The atmosphere was harmonious yet professional beyond my expectations. Loved it!"
