🗣️ Founder takes
What founders are saying about the businesses on Build Radar.
another api wrapper
14I like how quickly they get traction - could have huge potential and the business looks simple to copy!
1saw the foudner discussed his growth hack on hacker news, the product is simple but it needed som strong messaging to work
21tbh, I dont know why this worked, the market was crowsed and llmlite was opensource!!! anyone knows what was the edge?
18i know someone made $3m in 6 month doing this - he sells each ebook for $48 and you cna add your own child image as teh hero character in the book
27network effect is probobly teh best moat for them
26the whole product is an API call to vision models - they nailed the execution side
55it is pure execution with almost no mote
1it turned out google is not going to replace them anytime soon .. they are getting some moat in automation side ...
1europe is mess when comes to governance and security related
simple and high margin business - but there are many players and quality of service is vey important
18I see some founders already started building this- infra is hosted by AWS so the rest is just resource manganese and delivering high uptime service
1crowded space- it needs lost of funding to get off the ground
this needs human like voice to be valuable and generic text to voice doesn't cut it
bending spoon bought them for a reson ..
literally has nothing, i don't know why people pay so much...
1AI has already made creating designs so easy that the underlying editor is becoming less valuable.
Cursor proved developers will pay for AI that writes code. The bigger opportunity is an AI-native development platform that can build, test, deploy, and maintain entire products.
