Chase is SUPER conservative on CLI or initial CL.
If you are a chase customer and have had good account activity (deposits, decent average balance, no NSF etc) walk in to a branch and speak to a manager see if they can help with a fast approval and high limit.
Chase told me if I deposit 100k in personal savings, they will set me as a private bank account and use that relationship to give any business card i want (if business is 2years +, and enough income to support the line you are requesting)
But there are so many better options out there that I closed all my chase accounts and moved to another bank.
Keep in mind, too, that Chase treats their Ink cards only as quasi-business cards. The credit limit that you get will count against your personal credit exposure with the bank.
Here's how I know that: A few years ago, I applied for and received a $100K SL on my Chase Ink Business Preferred card. Several of my staff are authorized users on the card, and we all travel a lot overseas, so I needed a higher limit.
Chase originally offered $50K, which wasn't sufficient and I appealed for a higher limit. We had to send them financial records for the company, a nonprofit organization with an annual budget of around $8 million.
Interestingly, Chase counts the $100K limit against my personal credit profile, which I discovered the next time I applied for a personal Chase card. They nearly denied me the Amazon Prime card due to my "overall credit exposure" with the bank. So having the Ink Preferred card makes it nearly impossible for me to get additional personal Chase cards or CLIs on my other existing Chase cards. Of course, YMMV.
