Capital One Venture X Business
Earn up to 400K bonus miles: 200K miles when you spend $30K in the first 3 months, and an additional 200k miles when you spend $150k in the first 6 months.
My take: The Capital One Venture X Business card is Capital One's business version of the Capital One Venture X Rewards Credit Card. It comes with a high minimum spend, meaning this card will mostly target established business owners.
