Frequently asked

What makes a marketing startup "the best" in 2026?

On Startup Spotlight we rank by a mix of listing tier (Pro vs Free), recency, founder activity, and category fit. We deliberately exclude VC-track companies — this is a leaderboard for indie marketing founders.

How often is the 2026 ranking updated?

Continuously. Every new submission and tier upgrade re-orders the leaderboard. The page is rendered fresh on each request, so the order you see is the order right now.

Can I get my marketing startup added?

Yes — submit at startupspotlight.co/submit. Free listings include a verified badge embed; Pro listings (£49 one-time) include a permanent do-follow backlink.
