You've had a brilliant business idea. At least, you think you have. What do you do next? Evan Davis speaks to three successful entrepreneurs- including former contestants on The Apprentice and Dragons' Den. Where do the best ideas come from and how do you know when they are worth pursuing? What are the top tips for pitching and when is it time to let an idea go?

Evan is joined by Rob Law, the inventor of the Trunki ride-on suitcase for kids, Pippa Murray, founder of the nut butter brand Pip & Nut and Tom Pellereau, who invented the curved nail file for his company Stylideas.

Why do advertising agencies use fear to get us to part with our money?

Advertising agencies and marketing people use different techniques to push our buttons. Humour is one. But what about fear? Do they sometimes try to scare us into buying? Or is it a gentler art- playing on our insecurities about things like old age, poor health or thinning hair?

Evan Davis speaks to Sir John Hegarty and Ian Gathard from the advertising industry and psychologist Juliane Beard, who studies how the brains of consumers work.

When Shivaun and Adam Raff's shopping and price comparison website all but vanished from Google's search results just days after launching, the pair began a gruelling legal battle that would end with a landmark judgement and the tech giant receiving a then record fine.

European regulators found the search engine guilty of abusing its market dominance by making its own shopping recommendations appear more prominently than rivals' in its search results. Google spent seven years appealing its €2.4bn fine, but eventually lost in September this year.

In their first interview since that verdict the Raffs tell Evan Davis the story behind their website - Foundem - and what they learned about big tech, regulation, and themselves during their almost 20-year fight.

Evan is joined by:

Shivaun and Adam Raff, co-founders, Foundem; Anne Witt, professor of law, EDHEC business school.

When a company finds itself facing war or natural disaster how can it get staff out of harm's way, and is there any chance of ensuring business as usual?

Evan Davis speaks to one business leader who helped move hundreds of staff out of Ukraine, Belarus and Russia when war broke out in 2022. Two crisis response companies explain how they have been helping clients with people and operations in Lebanon, Israel and parts of the USA recently hit by hurricanes.

Plus, what is an employer's obligation in these situations, and do the same rules apply to international as well as local hires?

Evan is joined by:

Ann Roberts, chief people officer, Flo; James Waddington, global director of security assistance, International SOS; Elmarie Marais, founder and CEO, GoCrisis; and Anna, an employee at Wildix.

It must be one of the most-maligned professions out there - on a par, perhaps, with traffic wardens - but debt collectors perform a vital service to businesses and the wider economy. So why do we love to despise them?

Evan Davis and guests discuss the industry's inner workings, from the public image of aggressive, burly bailiffs, to the reality of repayment plans prompted by artificial intelligence. We ask how most try to ensure they collect debts fairly, and also hear the other side of the debt story - how damaging and stressful it can be for businesses who desperately need the money.

Plus, why do we find it so hard to talk about debt in the UK? We hear about the industry's efforts to tackle the stigma.

Evan is joined by:

John Pears, UK CEO, Lowell; Amon Ghaiumy, co-founder and CEO, Ophelos; Dana Denis-Smith, CEO and founder, Obelisk Support.

Side hustlers are seemingly everywhere - some surveys suggest they account for around half of UK workers - and stories of getting rich quick and abandoning the 9-5 are plenty. But the reality for many is much less glamorous: long hours; a precarious balancing act with the day job; and a good chance of failure.

Evan Davis speaks to side hustlers, and their employers, to find out what it’s really like balancing two jobs at once. Plus, why is side hustling so popular anyway? Does it reveal a flourishing entrepreneurial spirit in the UK, particularly among young workers, or is it a symptom of a changing relationship between employer and employee?

Evan is joined by:

Julian Douglas, global CEO, VCCP; Ewen MacPherson, chief people officer, Havas UK; Karen Burke, founder, Go Goosey.

The UK's power grid is undergoing a huge shift towards renewable energy, but running homes and businesses solely on this new form of electricity will be a delicate balancing act and will pose new choices for consumers.

Evan Davis and guests discuss the challenge of matching supply - from wind and solar - with an increased demand from electric vehicles and homes using heat pumps rather than gas boilers.

Part of the solution could be consumers themselves - homes with EVs, solar panels or battery storage could act like mini power plants, sending energy back to the grid, as well as taking from it, and getting paid in the process. But that two-way exchange could bring harder decisions - would you let your energy company switch off your fridge for an hour to ease pressure on the grid?

Evan is joined by: Cordi O’Hara, president of UK electricity distribution, National Grid; Hamish Phillips, net zero business development director, Centrica; Jordan Brompton, co-founder and chief marketing officer, Myenergi.

Private schools in the UK are mostly registered as charities – but they are also businesses – businesses in the sense that they sell a service to paying customers.

They’ve recently been in the news because the new government has said it will remove their exemption from VAT.

In this episode we take a look at the business of private education: how it works, how much money is made and what will happen when exemption from VAT is removed from school fees.

Evan Davis is joined by: Geoffrey Stanford, Head of Royal Grammar School Newcastle Jesse Elzinga Head of Sevenoaks School Cheryl Giovannoni, CEO, Girls' Day School Trust (GDST) Duncan Murphy, Director of Education, MTM Consulting

All eyes have been on the new prime minister as he, and his team of ministers, settle into their jobs running the country.

In this episode we consider the management challenge of taking over and starting a new role, maybe changing the direction of an organisation.

Three leaders from the world of business and the charity sector share their experience of coming in as a new broom, reflecting on the mistakes they made and advice they'd offer to the new Prime Minister.

Managing the rituals of a loved one's death can be both bewildering and expensive.

And although no-one wants to think about it being like buying a holiday or car, it is a business with a supply chain involving funerals, burials and cremation.

A couple of years ago the Competition and Markets Authority - which protects people from unfair trading practices - carried out an in-depth investigation into the funeral market because of the “surprise” people experienced at the final cost of that farewell.

On average people spend about £4,000, so what do you get for that and how is the industry changing?

Evan Davis is joined by: Gill Stewart, Managing Director, Co-op Funeralcare Alison Crake, Senior Partner, Crake and Mallon Funeral Directors Kate Tym, independent celebrant And Greg Cranfield from JC Atkinson coffin makers.
