How She Turned a Crowded Tube Ride into a Deep Tech Startup (and Nearly Lost It All) | Dash Tabor
Thu Nov 20 2025
What if your business could predict the future ā even with barely any data?
In this episode, I sit down with Dash Tabor, founder and CEO of TUBR, a predictive analytics platform turning small data into big insights.
Dash started TUBR after one too many packed Tube rides in London ā and ended up building a deep-tech company using a physics-based machine learning engine that helps small businesses forecast demand, sales, and staffing needs with minimal data.
But her journey wasnāt smooth.
Sheās lost Ā£500k in a day, rebuilt her team after losing her co-founder mid-fundraise, and turned down ālife-savingā investor cash on moral grounds ā all while keeping TUBR alive and growing.
We get into the raw parts of being a founder:
- Fundraising in a volatile market
- Building deep tech without a technical background
- Understanding investor psychology
- Rebuilding after disaster
- And why she left London for Sheffield
This is one of the most brutally honest founder stories yet.
