Solo founder. Find Feny + ReadReceipt.

About

Flexitarian. Spent years travelling with vegans and watched the same problem repeat. The sad salad at the end of a long search. The waiter who said vegan and meant something else. Built Find Feny because the decision layer did not exist. Also building ReadReceipt: know when your proposal was opened and which pages they read. What I am building: Find Feny: free vegan signal tool for travellers. findfeny.com Feny Verify: ingredient verification for vegan travellers. Coming to iOS. ReadReceipt: document tracking for proposals and contracts. Solo, bootstrapped. Happy to talk about any of it.

🚨 Vercel and Product Hunt are teaming up for a special launch day

We re teaming up with @Vercel for a special launch day on Product Hunt.

If you re building on Vercel, schedule your launch for midnight PT on April 17 and tag it under 'Vercel Day' to be included in a dedicated leaderboard for the day.

🔥 Get more points by launching on Alpha Day

We re trying something new on Thursday: Alpha Day.

The idea is simple. If this is the first time you re launching your product anywhere, you can tag it alpha and get a boost to your points (and land on a special leaderboard).

When do you follow up after sending a proposal?

I ve been thinking about this a lot recently

Sending is one thing, but knowing when to follow up feels like the hardest part

Too early feels pushy
Too late and the deal is gone

Curious how others approach it
Do you have a system or go by feel?
