Why “Jandshake”?
Two faces. One handshake.
The name joins two ideas, and so does the product.
Janus
The Roman god of doorways and beginnings, with two faces: one looking out, one looking in. Every deal has two sides, and Jandshake looks both ways: toward the people pitching and the people deciding.
Handshake
The moment both sides agree. Everything in Jandshake is built to get you there faster, with trust on both sides of the table.
Our mark is a pair of interlocked links, each with a curly-brace side, and two faces looking at each other across the gap.
How it works
Share. Track. Review. Decide.
