Risk and Stage

• Keystone Capital has a wider view. They often invest in businesses that are already making money and just need help to get bigger. This means they are often less risky than early-stage investors.

• Westbridge Capital typically deals with much larger amounts, often in the millions, as they work with established businesses. Their investments are usually for big ownership changes or major expansion, not small early-stage funding.
