I have read till 1334 ( RAW ), it was released few hours ago. I wont give any spoilers. MC keeps on trying to lose money but everytime something *new* happens and he gains money. Take it as slice of life not as business management.
Semi-spoiler --
companies MC has at 1334 chapter -
1. 2 Gaming companies, 1 VR game company
2. House rental company
3. Cafe + computer
4. "Suffering" Travels company ( Newest )
5. Investors company
6. Company than supports indie game developers
7. Twitch like company
8. Webnovel like company
9. Movie shooting company
10. E sports like company
11. Phone company
12. Physical experiance shops
13. Gym
14. Food delivary
15. Delivary company
16. steam ( gaming ) like company
Companies are written in random, dont worry about knowing which company is next.
Spoiler end ---
You might think Author would ignore some of them but author tries to combine them.
I'll give an example -
"After she completed shooting ad for new game she came to new home ( by home rental company ). After practicing "certain Gym" equipment, she went to play with "certain brand's" VR device"
Author also tries to give reasons for not falling to "linkage" with other companies.
I really hope author wont launch more companies, it would be harder to not ignore some of them
