The idea
What it is
The problem
A marketer at a developer tool company hears about Can I Vibecode It on day 3. By then 10 sponsors have already bought in and the 10th slot for August had gone for $1,199.
The first slots sold at $299 a month just days before. Catching that window meant watching X all week, and nobody at a tool company is paid to do that.
The product
Open the weekly board or its email. Each listing shows a product getting attention right now, with its monthly traffic, sponsor format, price and slots left. Click the contact link and book a slot before the price moves.
Three things set it apart from watching X yourself.
- 10 to 15 products a week, picked because they are taking off that week
- Products with no sponsor page yet are contacted and asked whether they want to test sponsorships, so their slots show up here before anywhere else
- Founders can submit their own open slots through a form
The weekend version: a sheet of 10 products with open slots, sent as one email to 50 marketers.
Who pays
- Buyer
- A marketer at a developer or AI tool company with a sponsorship budget, the week after they found out a launch's first slots were gone before they heard about it.
- Price
- Starting point: $29 a month for the board and email, the price of Stalkr's Starter plan for tracking mentions on X and Reddit; catching one slot at $299 instead of $1,199 saves 31 months of it.
- Also pays
- Founders with open slots, for a $29 featured listing in that week's email.
Why now
New products go from idea to sponsor page in days now. In early August 2026, Can I Vibecode It went live 5 hours after Pieter Levels replied "Can you make it?" to the idea on X.
It crossed 80K views and closed $8,000+ in sponsorship deals within 2 to 3 days. The next month's slot was already expected to go for $2,500.
How to validate it
- Track 5 new products getting attention on X for one week and ask each about sponsor slots. Pass: 3 or more reply with a price and format within 72 hours.
- Email 3 real early slots to 50 people in marketing roles at tool companies. Pass: 5 or more click through to a contact link.
- Ask 10 of those marketers what they would pay a month for the board. Pass: 6 or more name $19 or more.
- List one product's open slots and ask its owner after 2 weeks where each new sponsor came from. Pass: 1 or more sales came through the board's link.
