From Square Windows To £1 Billion Valuation: John Davies' Entrepreneurial Journey

John Davies built the biggest double-glazing company in South Wales by age 25 with one rule: square windows only. Then scaled a telecom sales business to 1,500 salespeople valued at nearly £1 billion.Andy Gwynn unpacks the lessons: simplify products ruthlessly, sell premium never cheap, test and adapt relentlessly (one phone per week became one per hour), challenge assumptions (evening TV ads worked when everyone said daytime only), and know when to take the offer instead of chasing future valuations.John shares how he used Boolean search on LinkedIn to target senior lawyers (excluding trainees), placed video ads under £1 per click, and why strategic partnerships beat direct outreach for risk-averse professionals.John's LinkedIn:https://www.linkedin.com/in/justjohndaviesJohn's Consultancy:https://the-johndavies.co.ukAndy's LinkedIn: ⁠⁠⁠https://www.linkedin.com/in/andygwynn⁠⁠⁠3degrees Social: ⁠⁠⁠https://www.linkedin.com/company/3degrees-social
