How it works
Three steps. Then it runs itself.
Open the account
Get your Trensa account and cards. Move money in, spend like normal.
Spend and annotate
Every charge is categorized. Add a one-line note when context matters.
Investors see it live
They open a link. Runway, burn and progress, current to the minute.
Why this exists
Most startups die quietly, and the hard conversation only starts when the money is gone.
Trensa keeps the numbers in the open the whole way through. If it works, your investors watched you build it. If it doesn't, nobody is surprised and nobody is accused.
Before Trensa
Quarterly email, written at midnight, out of date on arrival.
After Trensa
A live page. Investors check it themselves.
Questions
Do investors see every transaction?+
You decide. Share totals and categories, or open up line items.
Is it a real bank account?+
Yes — an account, cards, transfers, all in one place.
What if I forget to annotate?+
Trensa nudges you on anything unusual. Everything else is auto-categorized.
Can I still write an update?+
Sure. Most founders add two lines a month and stop there.
Which startups is this for?+
Teams that have raised a seed or Series A and have investors to keep close.
Never write another update email.
