“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...”

“Could not sing their praises highly enough. Many a time have been able to find an exceptional talent through their system, but more importantly, there is never any hassle when it comes to dealing with payments, communication, or delivery. A great service and they are contactable and provide solutions”

“I think the concept works really well and is priced reasonably. Easy messaging with the lovely artist who is doing the illustrations for a children's book for me and also overseen by a Twine manager to make sure everything is going okay. I haven't used other websites who do the same thing, but have found this one works...”

“I needed to create a Movie Poster for my Animated Screenplay. So I asked a local Graphics shop. They gave me a referral to Fivver.com. I was unhappy with the work and poor English comprehension. 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...”

3–5 minutes. Tell us about your project, your timeline, and how you want experts to contact you.
Within 24 hours, you'll see a shortlist of vetted AI Engineers matched to your project.
Flexible payments on your terms, bill experts directly or use the Twine vault for added security.
Transparent rates, no hidden markup, and a payment path for every need.
Agencies bury a 20–40% markup inside the retainer, you never see it. On Twine, you set the price and you see the platform fee as a separate, explicit line. No surprises at checkout.
Prefer your own payment flow? Pay your expert outside Twine, incurring no commission fees. Most useful for ongoing or trusted relationships.
Funds are held in escrow and only released when you approve the deliverables. If the work isn't right, your money doesn't move. 10% commission on payments up to $10,000, just 5% on anything above.
Pick the role, the experience level and how long you need. We’ll show you what similar projects have cost on Twine. It’s a guide, not a quote.
