Sorry, let me try one. Do you think is still a good market to introduce another tool for teams? Our approach is a little bit different, i think, we saw a lack of distributing useful content between team members.
I think the market of "tools for teams" is virtually limitless. The question you should be asking is whether people want your tool in particular.
I spent some time on your site and it took me a long time to understand what your tool does. You need to make it a lot clearer. Here's a good exercise for this.
1) Find someone you haven't told your idea to
2) Show them your home page. Let them read it for 30 seconds.
3) Close your laptop. Then, have them explain what Grobyk is in their own words.
If they can't do that, you need to improve your home page.
We spoke with teams about the idea and they said that also they had this problem. We started from our problem and then we decided to make it a platform for teams. We will work on the first page, we know that is not so friendly but thank you for your advice, we will try to see the results. Another quick question is that if is a good approach to attract customers by searching developers/bloggers from different companies and direct email them with our idea or is it to forced? We are now focused only on technology/business/startups fields. We want to attract teams from these fields.
