Once your profitable and have a concept that works - finding investors is not the problem, its getting rid of them. Who doesnt want to put money into something that has proven to work and make a return?

Seeding and funding is more for people trying to build a concept they think will work, and need investors to make it happen.

You guys are doing well, focus on increasing your revenue, monitization strategies and customer acquisitions.

Dont give away a bit of your company for more capital - unless you fear your company is about to close if you dont get funding - then push on - learn to do more with less just like you did to get to where you are today. Most services are BS when it comes to expansion and growth. So my advice is always avoid funding if you can -

the benefits
-You stay in complete control - no responsibility to investors, no debt, if you actually solve the revenue problems then you will be capital positive.

My recommendation is break down what excatly you want to do in terms of product developement and sales & marketing - come up with some budgets and what return you would expect - do this for two scenarios - one with no external funding and one with external funding - then get started with the no external funding

you will quickly see that had you got funding for sales and marketing you would be literally getting an investor to throw their money in bin on the condition you will go back to the first plan anyway just to pay back your investor.

Really hope this helps you out, all the best
