London, England, United Kingdom
Trumpet is a UK-based B2B software company founded in 2021 that builds AI-powered, buyer-facing sales execution software. The product allows revenue teams to create personalized, trackable microsites called pods, centralizing decks, demo recordings, and customer success collateral into a shared digital space. An AI copilot layer, launched in 2026, automates the creation of sales rooms, mutual action plans, and executive summaries from recorded sales calls, and continuously surfaces contextual content based on buyer engagement signals. The company was co-founded by Nick Telson-Sillett (CMO), Andrew (operations and product), and Rory Sadler (CEO), who joined as a third co-founder specifically for his sales expertise. Trumpet reached approximately $8 million in annual recurring revenue as of mid-2026, growing at over 150 percent year over year, and counts more than 5,000 paying customers including Stripe, Gong, and HubSpot. Total funding raised stands at roughly $8 million across a pre-seed, a pre-seed boost, and a seed round. Nick Telson-Sillett previously co-founded Design My Night, a London nightlife booking platform bootstrapped and angel-funded over seven to eight years before being sold for over $30 million to a UK software house in 2022. The proceeds, combined with angel investing experience across more than 50 startups, informed the more capital-efficient and brand-led approach the founders brought to Trumpet.
