From a napkin sketch to a year of full tables

In November 2024, Dinners With Friends was a revived idea and a napkin sketch. By the start of September 2026, it had welcomed more than 500 guests across 50 dinners. Dates were routinely selling out six to eight weeks ahead, and nearly all of the remaining 2026 calendar was booked.

Pamela Silkstone first ran the concept twenty years earlier: put people who have never met around one table, give them a host, and make the first conversation easier. I took the relaunch from idea to first version, first paying customers and a business with more demand than seats. Along the way I built the brand, website, booking system, internal tools, mobile app and the search programme that now brings new people in.

The search programme delivered 5,530 Google clicks in June–August 2026, up 66.1% on the previous three months, alongside 381,345 search impressions. Building and maintaining a library of local guides gave the business a way to be discovered by people looking for food, activities and places to meet across Exeter and Devon.
