5 min readStartup Ideas Brainstorm: Steal This $130k/Month Idea
The host opens with a confession: Danny Grant, a previous guest on the podcast, sent him a list of 139 startup ideas after their conversation, and they never got around to discussing them on air. So he's going through the most interesting ones himself, rating them, explaining how he would build them, and flagging which ones he thinks are traps. The throughline is that good startup ideas often come from unbundling existing platforms, serving specific niches with dedicated tools, or applying a proven format to a new vertical — but execution matters more than the idea itself.
Product-Specific Tools and Niche Website Builders
The first idea that catches the host's attention is a dedicated document format for writing product specs — essentially Google Docs for product managers, with inline JIRA creation and common threads built in. He estimates people would pay $20/month for it. His build strategy: outsource the MVP to an agency, then partner with a creator like Lenny Rachitsky (or an up-and-coming version of him) to get distribution. He would not build this without buy-in from two to four creators first.

In this episode, we explore 8 standout startup ideas from Dani Grant’s list of 139. I’ll break down why each idea has potential or pitfalls and share the frameworks and strategies I’d use to grow these businesses.
Here are the most interesting ones (with my takes):
1) Product Spec Doc SaaS
• Google Docs for PMs
• Pricing Potential: $20/mo
• Partner with PM influencers (e.g. Lenny Rachitsky )
• Build MVP, then get creator buy-in
• Solid idea, but needs influencer partner to succeed.
2) Developer Portfolio Site Builder
• Like Format but for devs
• $15/mo avg per user, low churn
• Start by designing for influencer devs
• Build MVP after refining the concept
• Great cash flow biz. Niche website builders still work in 2024!
3) Blog + Newsletter in a Box
• Set up blogs like Fred Wilson’s AVC
• Use existing tools (Substack, WordPress)
• One-time fee, cold outreach model
• Good side hustle. Keep it simple, don't try to be Substack 2.0.
4) JSFiddle Meets Twitter
• Social code sharing + memes
• Devs love to remix and share
• Build on existing dev culture
• Compelling idea. Devs crave better social tools.
5) Shopify for X
• No-code marketplace builder
• No-code messaging app creator
• No-code Instagram clone maker
• HUGE potential. The unbundling of Shopify is coming!
6) HQ Trivia for Dating
• Live, gameshow-style dating app
• Start in NYC or LA
• Make it feel like reality TV
• Love this. HQ format will make a comeback in new niches.
