Frequently asked questions

Below you'll find answers to the questions we get asked the most about booking a YC founder as a contractor.

  • I'm looking to hire in full-time. Can I do this here?

    Usually the YC teams are looking to do contracting either after shutting down their own startup, extend their runway by offsetting some costs or find a new journey. However, some founders might be willing to join your company after the initial project was finished, if they liked what they worked on.

  • What's the timeline? Is the budget pre-defined?

    Once you've entered your proposal project, we try to find the best team for the gig as soon as possible. Both parties are want to move fast. The budget depends by the scope of your project and is negotiated by the team; not us.

  • How is the project billed?

    We usually encourage to do project based billing. Hourly/daily billing does not incentivize the teams to move fast. However, maintenance and additional iterations might be billed by the hour, depending on the contract.

  • Will the team join our Slack/Notion/Basecamp?

    Yes, we highly recommend the team to join your companies communication platform and project management tools. NDA's included.

  • How is payment and contract compliance handled?

    We use Deel (W19) to handle all payment processing and legal compliance.

  • Is there any commission using this service?

    No. Book a YC Team is free of charge. To support the YC community we do not charge any commission per introduction.
