About Greg Isenberg

Hey, I’m Greg. I’m CEO of Late Checkout, a holding company building community-based internet businesses, and host of The Startup Ideas Podcast.

I’ve started and sold three venture-backed community companies and advised companies including Reddit and TikTok. Now, I self-fund things and share what I’m learning in real time.

Practical ideas, without the gatekeeping

I’m interested in what you can actually build: a useful product, a focused service, a small software business, or a community people care about. I explore opportunities with founders and operators, test AI tools, and break down the workflows behind the results.

This publication turns those conversations and demonstrations into articles you can revisit while you work. Expect specific steps, frameworks, and examples—not a promise that pressing one button creates a successful company.

Find your starting point

• Startup Ideas: discover niches, customer problems, and business models worth investigating.
• AI Agents: learn how to connect tools, supply context, and build workflows with clear boundaries.
• Vibe Coding: move from an idea to a working product through planning, testing, and iteration.
• Marketing & Growth: work on distribution and customer acquisition, not just the product.

Keep building with me

I built Idea Browser to help surface startup ideas and trends. You can also listen to The Startup Ideas Podcast on Spotify or Apple Podcasts.

I keep it practical and never gatekeep the sauce. Happy building.
