How does my team start?

Your team starts from its own inbox.

Example, fictional suppliersKestrel ToolingDate movedPrice changedOrder 7231
  1. 1Forward one email.

    A supplier email, a PDF invoice or a receiving report. Later, one forwarding rule covers the rest.

  2. 2It’s filed with its order.

    Each order shows what was promised, what changed, what arrived and what was billed.

  3. 3It flags what changed.

    Each flag shows what changed, before and after, and the document it came from. An order on track says so.

Can we trust what it says?

Every number comes with its source. When it isn’t sure, it says so.

Example, fictional suppliers

Every figure shows where it came from.

Needs filing

Kestrel has two open orders, 7231 and 7240, and the email doesn’t say which. Kynthar files it to neither, shows you both, and you pick one.

Your data stays yours.

  • It never emails a supplier or changes your systems on its own.
  • Walled off from every other company, in the database itself.
  • Encrypted in transit and at rest.
  • Never used to train AI models.
  • Delete your account any time: it closes at once and your files are erased.
  • Not yet SOC 2 audited.

What does it cost?

Free for 30 days. Then $1,250 a month, only if you choose it.

That covers your whole team.

  • Unlimited users, 2,500 emails and documents a month under fair use, no overage charges.
  • Or $12,500 a year, two months free.
  • No credit card for the trial. Nothing is billed when it ends unless you choose a plan.
  • Larger organizations: an annual contract sized to your procurement volume.

Who is behind it?

“I built Kynthar for where the money actually leaks, because I watchit leak every day.”

Josh Spadaro, founder. Runs procurement data at a global manufacturer.
