London startup Quibly Tech raises £450k for AI caption generator

Creators, agencies, and businesses can use an AI-powered platform developed by Quibly Tech Limited to generate social media captions. The London-based company has secured £450k in a new funding round to support its multi-language software. This technology allows users to establish custom brand-voice profiles for consistency across posts on Instagram, TikTok, LinkedIn, Twitter, and Facebook.

The investment values the business at an estimated £5.6m. According to recent filings, the total capital raised by the firm during 2026 now stands at £1000k, an increase from a previous round of £550k. These financial updates were recorded following a share allotment and formal documentation process completed in August.

The startup was incorporated in May 2025. Its primary service addresses the need for fast, viral-ready content within the retail and internet mail order sectors. The platform ensures that every generated post is platform-optimized for each social network.
