As an AI language model, I can provide you with some insights on what makes an investor good enough to sell your products. However, it's important to note that the suitability of an investor greatly depends on various factors, including your specific business, industry, and goals. Here are some key aspects to consider:

1. Industry Experience: A good investor should have relevant industry knowledge and experience. They can provide valuable insights, connections, and guidance specific to your product or market. For example, if you have a tech startup, an investor with a background in the technology sector may be well-equipped to understand your product's potential and help you navigate the industry landscape.

2. Network and Connections: A well-connected investor can open doors to potential customers, partners, or other investors. Their network can help you gain visibility and access resources that are crucial for selling your products. Look for investors who have a strong track record of building relationships and have connections in your target market.

3. Financial Resources: Selling products often requires financial support for activities like marketing, distribution, and scaling. A good investor should have sufficient financial resources to not only invest in your company but also support its growth. They should be able to provide the necessary capital to help you reach your sales goals.

4. Alignment of Interests: It's important that the investor's goals align with yours. They should have a genuine interest in your product and a shared vision for its success. This alignment ensures that they are motivated to actively support your sales efforts. Look for investors who understand your product's value proposition and believe in its potential.

5. Track Record and Reputation: Research an investor's track record to assess their previous investments and successes. Look for investors who have a proven history of supporting companies in achieving their sales objectives. Additionally, consider their reputation within the industry and among other entrepreneurs. Positive references and testimonials can provide valuable insights into their effectiveness as an investor.

6. Value-Added Support: Beyond financial resources, a good investor can provide value-added support. This may include mentorship, strategic guidance, operational expertise, or access to specialized resources. Evaluate whether an investor can bring additional value to your sales efforts beyond just funding.

Remember, the decision to choose an investor should be based on a comprehensive evaluation of their fit with your business. Seek out multiple options, conduct due diligence, and consider seeking advice from industry experts, mentors, or advisors before making a final decision.
