Side-project ideas with receipts.

The Stripe trust collapse is the strongest convergent signal in the corpus. averick (HN): 'Stripe froze our account and held onto $20,000 of our funds, promising to return it in 120 days. Now at 180 days, there's still no sign of our money.' Ashish T (Capterra, verified): account closed Feb 28 2025, balance still held a year later. Vanessa H: 'Has frozen funds without explanation, and several hidden fees appear over time.' Merchant Maverick aggregating hundreds of reviews: 'merchants wake up to find their account frozen with no warning.' Cases ranging from $3K to $800K.

Solo founders track MRR religiously and have no idea what their actual profit is. Stripe + Vercel + AI API + email + ads + contractor invoices live in 6 different dashboards. A real founder built a hackathon tool for exactly this and got 18 upvotes / 44 comments on Indie Hackers from peers saying 'I have no idea what mine is either.' Saveyond ([p_G_109]) is the closest thing and is pre-monetisation.

Founders waste weeks building features that users don't want because they lack a fast way to get 'transaction volume' as real validation. Traffic metrics are often misleading compared to actual payments.
