Traditional paid media management is broken. Agencies charge 10-15% fees, campaigns take weeks to launch, and optimization happens manually (if at all). We saw an opportunity to build an **AI media agent** that could: - **Plan** campaigns from a brief using frontier LLMs (GPT-4o, Claude 3.5 Sonnet) - **Launch** across 16 ad platforms (Google, Meta, LinkedIn, Microsoft, TikTok, Reddit, X, Pinterest, Snapchat, DV360, and more) simultaneously - **Optimize** autonomously with explainable changes and rollback The result: **autonomous media buying** that's faster, cheaper, and more data-driven than human-only management. ## Enter Amp: Agentic Coding Framework We chose [Amp by Sourcegraph](https://ampcode.com) as our development framework because it's purpose-built for **agentic systems**. Amp provides: - **Task routing:** Send briefs to planning agents, send optimization requests to analysis agents - **Tool orchestration:** Agents can call Google Ads API, LinkedIn Campaign Manager, Meta Marketing API, etc. - **Audit trail:** Every agent action is logged with rationale and metrics - **BYOK model support:** Swap OpenAI for Anthropic or Google without rewriting code Instead of building task queues, API wrappers, and logging systems from scratch, we used Amp's primitives and focused on **domain logic**. ## Architecture: Multi-Agent System Synter uses a **multi-agent architecture** where each agent has a specialized role: ### 1. Research Agent (Long-Context Models) **Model:** Claude 3.5 Sonnet (200k token context) **Responsibilities:** Analyze website content, competitor research, industry reports. Extract ICP signals, pain points, and messaging angles. ### 2. Planning Agent (Reasoning Models) **Model:** GPT-4o or o-series **Responsibilities:** Take campaign brief + research → generate channel mix, budget allocation, audience targeting, keyword lists, ad copy variants. ### 3. Creative Agent (Vision Models) **Model:** Gemini 1.5 Pro (multimodal) **Responsibilities:** Generate ad copy (headlines, body, CTAs), analyze existing creative for patterns, suggest image/video concepts. ### 4. Optimization Agent (Fast Reasoning Models) **Model:** GPT-4o or Llama 3.3 (cost-effective) **Responsibilities:** Monitor performance daily, recommend budget shifts, creative rotations, negative keywords, audience adjustments. ## Platform Integrations: 16 Ad Platforms, 1 Unified Interface Building native integrations with **Google Ads, Microsoft Ads, LinkedIn, Meta, Reddit, X, and more** required wiring OAuth flows, API clients, and entity normalization. ### OAuth & Scopes Each platform requires OAuth 2.0 with specific scopes. We built a unified OAuth handler in Amp that: - Redirects users to platform authorization pages - Stores encrypted tokens (access + refresh) in the database - Auto-refreshes tokens before expiry ### Agent Tools for Platform Actions Amp's tool system lets agents call platform APIs as functions. Example tools: - `create_google_ads_campaign()` → Creates campaign + ad groups + ads - `update_linkedin_budget()` → Adjusts daily budget - `add_negative_keywords()` → Adds negatives at campaign/ad group level ## Results: Faster, Cheaper, Smarter With Amp powering Synter's agentic architecture, we've achieved: 2-3xFaster campaign launch (minutes vs. days) 35-50%Lower CAC with AI optimization $50k-$200kAnnual savings (no agency fees) ## What's Next: Agentic Ad Buying at Scale We're continuing to expand Synter's capabilities with Amp: - **TikTok and Snapchat integrations** (Q1 2026) - **Multi-touch attribution models** (time-decay, position-based) - **Advanced creative testing** (image generation, video analysis) - **Custom model fine-tuning** on customer-specific conversion data If you're building agentic systems or exploring **autonomous media buying**, we'd love to hear from you. ### Share Article [X / Twitter](https://x.com/intent/post?text=Building%20Synter%20with%20Amp%20by%20Sourcegraph&url=https%3A%2F%2Fsynterai.com%2Fblog%2Fbuilding-synter-with-amp)[LinkedIn](https://www.linkedin.com/sharing/share-offsite/?url=https%3A%2F%2Fsynterai.com%2Fblog%2Fbuilding-synter-with-amp)[Reddit](https://www.reddit.com/submit?url=https%3A%2F%2Fsynterai.com%2Fblog%2Fbuilding-synter-with-amp&title=Building%20Synter%20with%20Amp%20by%20Sourcegraph)[Hacker News](https://news.ycombinator.com/submitlink?u=https%3A%2F%2Fsynterai.com%2Fblog%2Fbuilding-synter-with-amp&t=Building%20Synter%20with%20Amp%20by%20Sourcegraph)### Stay Ahead of AI Growth Trends Get the latest strategies on AI agent marketing, autonomous growth loops, and programmatic campaigns delivered weekly.
