Cian O'Mahony

Full stack software engineer. Love building things.

Particularly interested in the 0 to 1 process of building products. Love thinking about product strategy. Like building really fast w/ quick iterations.

Started off working for Coca-Cola as a software engineer. Built Influme in my spare time, got it to $200 MRR. Learnt a lot about end-to-end product development, found out that marketing is hard. Quit Coca-Cola to travel Asia for 3 months.

The last 6 months I've been working with early stage startups. Built Offmap completely solo. Worked on an open source project forΒ Lucid.

Scaled irelandsaunas.com to 200k impressions with programmatic SEO.

Projects

Offmap

With the release of the OpenAI GPT Store, I decided to build a SaaS which allows users to collect email addresses from their GPT users. This is a great way to build an audience and monetize your GPT API usage.
