Hello! My name is Humberto Valle, I'm the founder of Unthink Digital Marketing (www.Unthink.me) I have been helping new businesses and startups for the better part of 10 years. I have sold 2 companies as well as failed a few others and currently ran my agency for 7 years.
To start I want to congratulate you for following a niche in a market that is poorly served. This will facilitate your go-to-market strategy. With that said, I do have to agree with the previous answer. You need to focus on only one channel, not necessarily a group but a distribution channel and method. For example, your lowest cost will always be direct to consumer through online sales. This means you need to have a website properly designed to funnel visitors, curious browsers and those with an actual search through the process of getting them exposed to the solution, interested in the product and brand, and wanting to try them.

By leveraging digital media you can then attain other channels as they approach you versus you diluting your efforts trying to get to them. What I suggest you do is have a really good website flow designed (a funnel from visitor to subscriber or purchase) so that you have good SEO, good Calls To Action, good images, good offers and good content demonstrating what your product solves. Get into Amazon. Position yourself in the right social media channels and with the right sort of updates and shares. Get on Linkedin and build relationships with the Presidents, CEOs, Managers, Franchisees, etc. in charge of making purchase orders. Use social media, including Linkedin to promote your value proposition (not the product or its price).

If you were to reach out to companies directly, is all about having a strategy.
Send a few samples to a few strategic clients ( headquarters of franchises or companies with subsidiaries and retailers) Don't waste your time trying to get in with small companies which can be just as hard as any other company.

If you would like some help creating a good marketing campaign and strategy for your product, please do consider us at www.Unthink.me - we have helped small businesses through the world, some universities and city level governments.

More details it will be a pleasure to answer in a call.

Recognizing a problem or need that you have is the step that triggers a search for more information. The strategies used to gather information tend to vary based on the size and scope of the purchase. Deciding which provider to use to install a new inground pool at your home, on the other hand, will involve calling around, reading company reviews, visiting showrooms, and talking with salespeople. According to Pardot, 70% of buyers turn to Google at least 2-3 times during their search to find out more about their problems, potential solutions, relevant businesses, etc. Many people also turn to social media and forums for recommendations. Let us say you are a marketing platform or agency. You could create content around link building, SEO, Facebook advertising, or any other strategy that your customers would be searching for. If you are an accounting software company, you might create content around helping solopreneurs figure out their finances for the first time. However, say the customer is evaluating marketing automation programs to help improve the sales funnel they created. They might request free trials of the different systems they are considering, have online demonstrations with each company’s representatives or view training videos to get a feel for how each system will perform. If you are running an accounting business, at this stage your customers would be evaluating different potential service providers.
