@athcanft Similar feeling, been grinding for 3 years on the side while working full time SWE job. Crossed $200MRR but still haven't hit that compounding point yet.

[Jack @jacklhanlon]

How about a hat trick ?

[Jack @jacklhanlon]

If you're not using /grill-with-docs what are you doing ?

[Jack @jacklhanlon]

Being a founder is being delulu enough to keep going, whilst being neurotic enough to keep your vision grounded in reality.

Day 48/90 · Building in Public 🏗️ 📷 MRR: $157.43 → $3,000 goal.

It has been a challenging month, but I've been able to complete the product improvements I wanted to hit before focusing on marketing. Now working with a local youtuber to do a review video for some reach.

[Jack @jacklhanlon]

@athcanft the brain fog from too much carbs is insane. I also find skipping brekkie and drinking coffee in the morning with 20 minutes of sunlight exposure helps.

[Jack @jacklhanlon]

@athcanft what about reddit ads ?

It's clear to see now with the price of RAM, how much context a human developer had to have in their brain before agentic coding.

@asmartbear What about a Pro $10/mo tier and Pro+ $20/mo tier? Pro has much more limited functionality than Pro+

[Jack @jacklhanlon]

@asmartbear Perhaps I shouldn't have given explicit numbers. The sentiment is that there is a "minimum quality threshold" where the AI tool goes from being a Toy in a companies experimental budget, to a critical product in their workflow
