Featured case study · AI & automation

Hermes AI Marketing Agent

D2C consumer-electronics brand on Shopify

A team of AI agents that runs day-to-day marketing for a Shopify store — writing product copy and blogs, auditing the store, planning social content, reporting ROAS, and creating Meta Ads and Google Ads campaigns. The team simply asks for things in plain English on Discord.

The challenge: A small team was spending hours every week on product copy, SEO fixes, social calendars, ad campaigns and reporting — across Shopify, Meta and Google — with no single place to run it all.
What we built: We built a multi-agent system on the open-source Hermes Agent framework: an orchestrator that delegates to specialist agents, connected to the Shopify Admin API, Meta Marketing API and Google Ads API, with a Discord interface and a store dashboard.

Questions

Before you share your idea.

What founders, product and operations teams usually ask us first.

Can we sign an NDA before sharing our idea?

Yes — an NDA is available before any discussion. Share your idea with confidence.

Which platforms and technologies do you use?

Flutter for cross-platform iOS and Android apps, native iOS where needed, React for web applications, and cloud backends and APIs. We pick the stack that fits your product.

Can you build an app for our hardware device?

Yes — IoT apps are our speciality. We have built apps that pair with BLE and Wi-Fi devices, such as a smart diffuser, a pet GPS tracker, smart locks and audio devices, including firmware-update flows.

How do we follow progress during development?

We work in agile sprints with a transparent process, so you always know where your app stands — and you talk directly with the developers building it.

What happens after launch?

We handle store deployment and provide post-launch technical support: maintenance, updates and improvements based on user feedback.

How quickly will we hear back?

Share your idea through the form or WhatsApp and we will get back to you within 24 hours. No obligation.

Can you add AI to software we already use?

Yes. We integrate AI into existing products and internal tools — assistants, smart search, summaries, document processing — and build agents that work with your ERP, CRM, email and documents.

Do you build ERP systems from scratch or extend existing ones?

Both. We build custom ERP modules around how your business works, or integrate and extend the systems you already run. A phased rollout keeps risk low.
