Honestly! I have recently bind up the operations of my IT service providing company. I'm just putting some of the knowledge over here, I hope you may find it useful.
Its better to do some research about the market before you trying to enter. As you are starting an IT company and looking for the market segment or looking to make potential customers, then you should be ready and focused.
There are so many industries, which needs the IT services, but I'll suggest to start from serving the clients from single industry. You can select any like banking, automobiles, health etc.
Now you may have a filtered market segment, so you can easily identify your customers. It will save your money, efforts and resources.
Next thing is research about the the specific segment market which you chose. What are the needs of that industry? What are the hindrances they are facing in their profession and how can you help them.
Now you can use google, yelp, linkedin etc to find and approach the respective people and can ask for their useful time. Remember, people only wants to listen their profits, so be ready along with research on the client as all people likes the attention.
There are some other techniques too like Digital Marketing and few off-site, that needs a proper strategy and implementation plans.
I hope it might be of your use. If you need any help, please feel free to connect.
I am actually part of a group that is working on a company in the same space, I reached out to you lets chat!
If you have content or anything engaging promote on Twitter and other social media (Bing, G+, Facebook) - each technical market segment has it's groups (lists on Twitter) on different groups. If you have something for developers or DevOps even github, stack overflow and blogs. LinkedIn is not truly a "technical" source, but works great for marketing, hr and some professional sectors. There is so much material and connection today that you really need to mold and nurture your own mix of channels and content. Basically, it's a big, noisy, confused world, so enjoy the work! :-)
Bela, The channel matters very little. You have prospects on every one. It is in the message. Does your message clearly state what problem you solve? Does it tell the prospect that you understand the emotions they have? Is it clear that by engaging with you there is a good chance that these emotions go away? Your prospects or ideal target market are experiencing pains. These pains do not change when they are on Twitter or Facebook or the web. You have to define you understand the problem, know the emotions or pains the problem is creating and are a choice to eliminate these pains. Your marketing has to reflect why you are a better choice than others in your space. We all have great customer service. Why using specific examples is yours better? We all deliver on time and on budget. What makes you different in these areas that everyone claims. A web site can say anything. You have to explain why you are different and better.
No one can offer any input of value without knowing what the target market/segment is.
Right now, I'm looking at the LinkedIn Sales Navigator. LinkedIn seems to be the best channel to approach people. But it's always best to create some context, follow them, comment, engage before sending a connection request.
Great feedback and useful pointers to take. Thank you all for the comments.
