“I am the Co-Founder and CEO of a Swiss-Insurtech startup. I was always doing the design of my powerpoint slides on my own. To design them took me a long time and it always looked bad. Until I found twine. Due to twine I found an amazing designer abroad. She is very good and fast. And I can now send her my powerpoint slides...”

I haven't used other websites who do the same thing, but have found this one works...”

Somehow, in an internet search, Twine.net came up, so I tried it. I think that the ability to see a Contractor's Portfolio is...”

“Went searching the web for a songwriter to help me with my timely COVID-19 related song. There's a lot out there, but finally happened across Twine. Found a nice young and talented fellow in the UK who would do it within my budget. And viola! a one day turn-around and a new song is shared with the world. I couldn't be...”
