How to SUCCESSFULLY launch your own, bootstrapped AI SaaS on PH while working in a full-time job?

Hi makers & hunters out there. I would like to draw your attention to an individual. He is a solopreneur, tirelessly working on his completely bootstrapped AI-SaaS venture after his regular job hours. The offering is now ready and he is on the verge of launching it, hoping to gain some impressive initial traction. He has grand ambitions to make his mark in the generative AI sector. However, he is currently bound by the shackles of his day job, which consumes 9.5 hours of his most productive time. Sadly, his job has become quite monotonous and dull for him. Nevertheless, he is determined to stick with it until his startup starts generating a substantial income (or until he secures funding) so that he can finally pay off his financial commitments. The guy is an expert in many areas, except for marketing and distribution, which is where he requires some assistance. Thanks ThatGuy
