The short answer
Jack & Jill suits a tech start-up, from Seed to Series C, hiring in London, New York or San Francisco among candidates already looking, and happy to pay on success. Umamy, a European player, suits a company hiring in Europe: its agents also go after employed people who are not looking, the message goes out from the future manager’s LinkedIn, and the price is flat per open role, no placement fee.
The maths

With Jack & Jill, Jill makes the introduction. With Umamy, the candidate gets a message from their future manager, from their own LinkedIn, after your approval: 1 in 2 people contacted reply.

When Jack & Jill remains the right choice
- You hire in London, New York or San Francisco, for tech profiles already looking.
- You would rather pay only on a hire, even if the bill follows the salary.
- You would rather be introduced to interested candidates than go and find them.
In those cases, Jack & Jill saves time. In Europe, and whenever the best profiles are employed and not looking, you have to go and find them, in the manager’s name: that is where Umamy makes the difference, at a price that does not depend on the salary.
