No. Antler is an inception-stage VC. You’ll get the earliest capital, hands-on guidance from partners who’ve built companies, and access to a global founder network — without the “school program” feel of accelerators or incubators.
We commit up to £500K at inception - and have the capital to back you all the way. When you're accepted into the Antler residency, you qualify for an investment up to £500K in the first 9 months post incorporation into your company. The terms are committed on Day Zero. The decision to invest is made during the residency - if you're building something exceptional, we move fast. Read about our investment terms here.
Yes. You’ll get the most out of Antler when you’re all-in. Momentum compounds when you’re fully focused. Founders usually spend 4–6 days a week in person with their cohort during the eight-week sprint.
We don’t invest in solo founders. Most people join Antler solo, but the goal of the residency is to form a complementary founding team. You’ll meet potential co-founders, test dynamics, and build your company together.
Our next UK residency starts September 23, 2026 in London. It runs for eight weeks, in person. If you’re invited to the Investment Committee, a build-and-raise phase will follow lasting up to 12 weeks.
We back outliers — founders with the resilience, energy, and ambition to build category-defining companies. We look for four traits: • Velocity — You move fast and deliver results. • Magnetism — You attract talent, customers, and investors. • Relentlessness — You push through obstacles to reach ambitious goals. • Spike — A rare skill, deep expertise, or unique insight that sets you apart. Learn more about what we're looking for in the scouting process here.
Highly. We back fewer than 1% of applicants. That means you’ll be surrounded by exceptional peers.
Antler is the first investor. We back founders at inception — often pre-team, pre-product, or pre-revenue. If you’ve already raised a meaningful pre-seed round, you’re likely too far along for our residency. That said, many successful Antler founders joined with elements already in place — an MVP, early customers, or a team. What matters is whether Antler can still be catalytic: helping you build momentum, form the right team, and raise your first significant round faster than you could alone.
Founders must either have the right to work in the UK or be actively working on a visa application by their first interview. If we make an offer and your visa isn’t secured yet, onboarding will be delayed until you obtain a visa or endorsement (such as a Global Talent Visa). If the visa isn’t secured by the end of Week Two, your offer will be deferred to the next residency if the issue is resolved.
The best founders don’t wait. If you’re serious about creating a category-defining company, Antler gives you the capital, network, and accountability to go further, faster.
