CONTACT

One inbox. One person reading.

Yearfold is built by one founder. The best way to reach me is email — I read everything personally, and I usually respond within two business days.

Email

hello@yearfold.com

For bug reports, methodology questions, story tips on tax or retirement-rule changes, advisor-reviewer inquiries, press, or general feedback. Plain text is fine; screenshots are welcome.

Or send a message from here

Same inbox, no email client required. Your reply-to address is whatever you put in the email field below.

Submitting sends your message to hello@yearfold.com and lists your email as the reply-to.

What to expect

A real reply, from a real person, in two business days or less. If a question needs a longer answer or research against a primary source, I’ll acknowledge first and then come back with the substance — I’d rather take an extra day than send you a confidently wrong answer.

If you’ve found a number that looks wrong — a tax bracket, a Social Security threshold, an IRMAA tier, anything — please tell me. Yearfold updates federal numbers on a known cadence (SSA in October, IRS in November, Medicare in January), but I’d rather hear it from you the day you spot it.

What email can’t do

I can’t give personalized investment, tax, or legal advice over email. Yearfold is a financial-education tool, not a registered investment adviser, and I’m a software engineer rather than a CFP® or CPA. For decisions about your specific situation — Roth conversions, claim timing, tax-efficient withdrawal sequencing on a real portfolio — please consult a fee-only CFP or a CPA who knows your full picture. Yearfold’s job is to give you the honest probabilistic math; their job is the personalized call.

For a specific kind of question

  • Privacy / data requests — see the Privacy Policy for the formal access / deletion / portability process, or email hello@yearfold.com with “Privacy request” in the subject.
  • Editorial-reviewer interest — if you’re a fee-only CFP, CFA, or tax attorney interested in reviewing Yearfold’s finance content, write to hello@yearfold.com with “editorial reviewer” in the subject.
  • About the founder — background and philosophy live on the About page.
  • How the math works — every assumption traces to a primary source on the Methodology page.

Operating entity

Yearfold is operated by Hyper Mind Technologies, LLC. For legal correspondence, address email to hello@yearfold.com with “Legal” in the subject and the matter will be routed appropriately.
