Startups are born to fail. Around three quarters of venture capital backed new companies never return cash to investors. Upscale is about the other 25%.

`I feel like I woke up one morning to find I have a board, investors and 80 people to manage - and I don''t have a clue how to do it.''
Asi Sharabi, co-founder, Wonderbly

At a time when more people than ever are starting companies in Britain - over 2,000 new businesses are launched every day - Upscale focuses on the moment founders floor the accelerator and their company goes from a bunch of friends in a co-working space to hundreds of employees often scattered around the world.

Speaking to some of the UK''s leading technology entrepreneurs and investors - including Brent Hoberman (lastminute.com, Founders Factory), Wendy Tan White (BGF, Moonfruit), Neil Rimer (Index Ventures), Suranga Chandratillake (Balderton Capital), Saul Klein (LocalGlobe), and Sarah Wood (Unruly) - who between them have built or backed companies worth billions, journalist James Silver covers the most pressing, practical and often painful issues founders face: from coping with stress to getting shot of a bad hire, to handling a tricky board member and opening a first overseas office.

By founders for founders, and those toying with starting a business, Upscale (based on the Tech Nation programme of the same name) avoids the theorizing and platitudes of typical business books, in favour of hard-headed advice from those who''ve succeeded - and the mistakes to look out for along the way.
