Wisry
Agentic ad platform that reverse-engineers the ads already winning in your market, rebuilds them for your brand, and launches them to Meta and Google.
Key features
- Competitive ad research agents: Analyze the ads currently performing in your market and reverse-engineer the creative patterns behind them
- Evidence-backed angles: Produces a set of six messaging angles per run, each grounded in observed market performance rather than a generic template
- Brand-matched creative: Rebuilds winning concepts as static and video ads in the customer's own brand rather than reusing competitor assets
- Direct campaign launch: Pushes finished creative live to Meta and Google, optimized for return on ad spend
- End-to-end loop: Research, angles, creative and live campaign run as one continuous flow instead of separate tools and handoffs
- Trained on $1B+ ad spend: Creative and targeting models are built on a large base of historical advertising performance data

Best for
- An ecommerce brand entering a new category and wanting to see which creative angles already convert there before spending

- A small DTC team without an in-house creative department producing static and video ads at agency cadence

- Launching Meta and Google campaigns directly from the creative step rather than exporting assets to a separate campaign manager
- An agency scaling creative output across multiple ecommerce clients without proportional headcount
