Lahboom
U.S. personal Amex Platinum
First Wave · U.S. personal Amex Platinum only
You paid for the card. Know what came back.
Record supported credits you actually received and see their recorded value against your annual fee.
We’re starting with up to 50 founding members so we can learn from your experience and shape what comes next.
Request an invite to be considered for Lahboom. Submitting stores your email for manual review. This does not create an account, grant access, start a trial, or send an automatic invitation.
This release supports U.S. personal Amex Platinum only—not Business Platinum or other cards. Supported statement credits only · not every official card benefit
Generic illustration · not Amex card art
How it works
Three steps grounded in the app you use today.
Lahboom is a tracking workspace for U.S. personal Amex Platinum statement credits in this First Wave. You choose which supported benefits to track and record outcomes yourself — there is no bank sync or automatic credit detection.

What you get
Clarity for recurring benefits — without the noise.
Built around periods, outcomes, and the True Value you assign when a credit mattered to you.
Benefit periods, at a glance
One combined outcome label sits above a slim 4px line, with “This period · N days left” beside it when space allows — the released Tracker treatment, not a thick progress pill.

CLEAR+: Not yet — waiting for it to post
Outcomes you can correct
Record a received amount and date, change an answer later, or remove a recorded credit. Standing status stays above the bar; polite feedback does not duplicate it as a second summary.

Fee context that stays honest
Home shows recorded received against your annual-fee assumption. The public fee calculator estimates net fee from True Values you enter — estimates, not verified bank statements.

Request My Invite
Lahboom is invite-only. Leave your email to request consideration. A founder reviews requests manually. Submitting does not guarantee admission and does not create an account. If you are invited later, you will sign in with that invitation. Pricing and checkout, if offered, happen only after a separate invitation and sign-in — not when you submit this form.
We store your email to review invite requests. We do not sell it. To ask for removal, contact hello@lahboom.com.
