OP you're just straight up not going to get people for who stability is a priority any time soon. Your target market is people who like to fiddle with their work tools, likely beyond pragmatism and in to productivity as a hobby territory. Guy that wants to get his organisation on to something and know he wont have to think about it again, ie the guy who cares about "built to last", is going to go Salesforce and call it a day.
When you say that it's for small businesses and it's really efficient and light, I think people will identify with that. As long as features keep getting added to platforms, we will always need a super lightweight version. Again, I hope you get some paying users right away!
I think I'm just missing something and I see these as clashing messages that don't get fully explained: this platform will make you smile and you'll have fun using it, this platform is faster than other platforms, and it's built for small businesses. I'd ask you "How?" for all three of those.
Just some thoughts from a marketer who thinks about positioning and looks at lots of landing pages. I hope you ignore all advice, trust your gut, and have tons of success :)
Get people on board with free product than offer value add. A CRM requires trust.. so spend money on the brand or give a free tier and build trust.
Does not answer why I would choose this over all the other 1000000 of CRM offerings (just in our office we tried Zoho, Close.io, Salesforce, Pipedrive,....).
Plus, not fully sold on the "Built to last - Wobaka is like your favorite craft beer or artisan coffee. Made with love and hand-picked ingredients. No mega-corp here." pitch.
Great effort tho.
