What AudioStack does
AudioStack (legal entity Aflorithmic Labs Ltd., incorporated February 2019, headquartered in London with offices in New York and Barcelona) operates an agentic audio production platform that converts briefs or raw text content into broadcast-ready audio without manual intervention. The platform orchestrates multiple third-party AI voice, music, and sound model providers (ElevenLabs, OpenAI, Google, Microsoft Azure, Amazon Polly, Cartesia, MiniMax, Resemble, WellSaid Labs; plus Epidemic Sound, HookSounds, and Soundstripe for music) under a unified production workflow that covers script generation, voice casting, sound design, multi-layer mixing, mastering, and broadcast-spec QA. It is offered through four products: InstantCreative (self-serve console for short-form ads), DynamicCreative (dynamic creative optimization for audio), CreativeEngine (embedded white-labelled API for platforms), and StoryEngine (long-form API for audiobooks, news, and editorial).
The company serves agencies, brands, publishers, AdTech platforms, and AdTech-adjacent media organizations, with named enterprise customers and case studies including McDonald's, Porsche, Mountain Dew, PRISA (1,250 radio stations across 13 countries), News UK, News Corp Australia, Handelsblatt, Pocket FM, Lowe's, Marks & Spencer, The Trade Desk, DanAds, adpaq, Bloomberg, Acast, EssilorLuxottica, the UK Government, and a leading US eyewear retailer (4,400+ localized ads across 890 stores). Its 2025 product expansion includes Octave AI, co-developed with News UK, which embeds the production stack into publisher-side advertising sales tools.
AudioStack operates a hybrid sales-led, product-led growth, and API-first distribution model. Revenue is generated through (1) usage-based CreativeEngine API licensing for AdTech and platform customers, (2) subscription console licensing via InstantCreative, and (3) enterprise licensing with dedicated technical account managers. The company has disclosed approximately $3.15M of pre-Series A funding led by Quadri Ventures in February 2024, earlier seed and angel rounds, and a prior $1.37M round with Crowd Media in 2021. Certifications include SOC 2 Type II, GDPR, CCPA, IAB, and AWS Qualified Software, and AudioStack (with DanAds) received the NAB Product of the Year Award in 2023.

AudioStack product offering
Product offeringCore offering
AudioStack is an agentic AI audio production platform that turns briefs or raw content into broadcast-ready audio without manual intervention. It offers two deployment modes: a self-serve console (InstantCreative, DynamicCreative) and an embedded white-label API (CreativeEngine, StoryEngine). The platform orchestrates multiple third-party AI voice, music, and sound model providers and handles the full production chain — script generation, voice casting, sound design, mixing, mastering, and delivery.
Product overview
AudioStack is an agentic audio production platform offered as a unified platform-plus-modules architecture. The core platform handles the entire audio production chain from brief to broadcast-ready output. Two deployment modes: Self-Serve Console (InstantCreative for quick ad creation, DynamicCreative for DCO campaigns) and Embedded API (CreativeEngine for platform integration, StoryEngine for long-form content). The platform orchestrates multiple AI voice, music, and sound model providers rather than competing with them, adding an intelligence layer for casting, mixing, and quality normalization.
