I actually saw this article somewhere and it was really good so I decided to share. I hope it helps you.

1. Ask for introductions – Over the 24 hours, reach out to 10 people and ask them to be your customer, and if they say no, ask if they can introduce you to someone who may benefit from what you’re offering. The point of this exercise is to get you into the habit of taking bold action and putting yourself out there. So it doesn’t matter who they are or what they say. Ask your buddies, ask your mum, ask anyone who’ll listen. From there you can put together a hitlist of ideal customers to reach out to.

2. Engage with influencers – Instead of reaching out cold, start creating content that industry influencers would like to share, then reach out and ask for their opinions on the posts. You can find influencers with tools like Buzzsumo. Look at what they’re sharing right now for content ideas. You can even open up conversations with influencers by including them in your post. Or just write about what you’re solving. If you know about key problems in the marketplace, then write about them and how they can be solved.

3. Connect via LinkedIn – Join LinkedIn groups for your target market. Reach out to those that post relevant ideas and questions and engage in discussions. Search for connections if you know who you want to reach out to consider searching for them and ask for introductions via your existing network, or invite them as a friend or use InMail to message them. Post updates that are relevant to one or more of your groups on LinkedIn. Also, consider building your credibility by publishing on LinkedIn Pulse.

4. Forums and Q&A sites – Sites like Quora, Reddit, Quibb, StackExchange etc. can be great places to find your target customers depending upon your niche. To start off, you may want to monitor questions and answers but then follow these tips to begin engaging with your target audience. Reach out to those that ask relevant questions. Answer questions about the problem you are trying to solve. Add a signature that includes a call-to-action or link to one of your posts.

5. Use your existing customers – Offer an incentivized referral program to your existing users when they refer other users to you. Use feedback like the Net Promoter Score to determine when you have achieved product/market fit. Ask if they’d be happy to give you a testimonial. Ask if they know someone else would also be interested in your product or service.

6. Reach out to complimentary startups – Ask to guest post on their blog. The challenge for most industry blogs is fresh content. So reach out to someone with a big blog to propose topics that would be of interest to them and offer to write it up for them in exchange for a link back to your site.

7. Watch your competition – Monitor social mentions. You will almost certainly have people talking about your competition on social media. Monitor social mentions for relevant conversations and complaints about your competitors. Join in on these conversations to build relationships and ultimately bring these people over to your business. Monitor their advertising with tools like Spyfu and SEMrush. They can help uncover keywords, advertising spends and provide inspiration for any online advertising you wish to engage in.

8. Cold email – Cold email has a bit of bad rap, but it’s probably the most powerful marketing channels there is. When used effectively, cold email can land you major clients. The key with this strategy is narrow and deep. Instead of spamming anyone who may or may not be a good fit for your company. Find 10 ideal clients, do seriously in depth research in them and their needs and approach them with a genuine, relevant, helpful message they’ll want to read.
