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 Data Scientists 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.
Estimates only. Actual budget is set by you and agreed with your expert before any work begins.
ESTIMATED RANGE
€3,000 – €8,000
Full possible range for a mid-level Data Scientist over 2–4 weeks
Post your project and meet your expert within 24 hours. Over 45,000+ high growth companies that trust Twine.
