See our guide to this year’s hottest new businesses and most exceptional founders in the complete 2026 Startups 100 index. Founders: Mark Walker and Mitch NickYear founded: 2024Website: revvedup.aiAccount-based marketing, or ABM, involves targeting high-value accounts with highly personalised, deeply-researched campaigns created specifically to target them. It’s known to be an effective strategy in B2B marketing, but it’s also difficult, time-consuming, and expensive.This is a problem that Mark Walker, co-founder and CEO at RevvedUp, experienced firsthand as a three-time chief revenue officer. He saw a big gap in the market for a solution that could help every B2B sales and marketing team run ABM and delight their target accounts.The result is RevvedUp, an AI-native platform that makes ABM more accessible, systematic, and impactful for teams at all levels. It helps to rapidly gather deep insights into target accounts, and craft campaigns that are tailored for them.Refined by a deeply knowledgeable product and engineering team, the RevvedUp platform can handle an entire ABM campaign, doing everything from account prioritisation and customised research to content creation and campaign execution. It can create unique blog posts, landing pages, direct mail, scripts, and social posts.This enables teams to run ABM at a fraction of the cost and time it takes to run manually, which in turn helps them better engage their target accounts, build quality pipelines, and drive their growth ambitions. It’s a more effective alternative to running high-volume, low-quality automated outreach campaigns.Today, the startup is backed by investment firm Salica, as well as angel investors. RevvedUp counts B2B tech companies, SaaS providers, and large enterprises with complex sales processes amongst its clients. It has also formed strategic partnerships with CRM software, sales platforms, and marketing agencies.In five years, Walker and Nick hope that RevvedUp will reach over £100m in ARR (annual recurring revenue). They hope to be working with thousands of top tier clients, supporting their marketing goals – and it looks like they’re revving up to get there.View the full Startups 100 Index for 20261. Omnea2.
