Tethered Wits' Sister Company

GSP is the official theatre production company of Gabbie Sills, with a strong focus on bringing new writing to the Off West End and beyond. We believe in the power theatre has to inspire, educate - perhaps entertain - and take us beyond comfortable existance.

Our Services

GPS offers a range of services, which can be tailored to the individual client. We both produce our own shows and support a wide range of other companies on the Off West End, at Edinburgh Fringe or on tour.


Whether you would like to bring us on board to oversee an entire project or need specific help in a certain area, please do get in touch! Our services include:

  • Productions

  • R&D

  • Bid Writing

  • Venue and Tour Booking

  • Running Budgets

  • Bookings

  • Recruitment

  • Marketing and Press

  • Events

  • Mentoring
