Quantive
Replace your net worth spreadsheet, no bank logins.
Quantive is a manual-entry net worth tracker where the server holds only ciphertext. A year of solo work; launched to the public in early June, relaunched on Hacker News on Wed 24 Jun with a rewritten frame.
What changed between my first attempt and the second (24 Jun): the title and the lede. The original frame led with encryption: "privacy-first net worth tracker, end-to-end encrypted". The new frame leads with the job: "replace your net worth spreadsheet, no bank logins". The encryption moved from headline to paragraph 2.
This reframe was not obvious to me before the launch. I built the product partly for privacy reasons, so I described it in privacy terms. The first month of sign-ups taught me that most of the people who actually converted were not really privacy-focused first... they were spreadsheet-fatigued first! People who had been updating a net worth spreadsheet every month for years and wanted something more structured, without handing a third party access to their accounts. Privacy is the reason they trust Quantive over a generic alternative. Spreadsheet fatigue is the reason they try it at all.
The 3 things worth sharing with this audience:
the non-goals section of every launch post did more work than the positive claims. Stating explicitly what the design doesn't defend against (active server compromise, compromised devices, metadata, forgotten passwords, etc.) converted skeptics faster than any technical detail about what it does defend against. The audience that reads launch posts on HN and privacy forums is looking for the place where you've overclaimed. Giving them that list preemptively moves the conversation to the substance.
the one-month-per-channel staging (Reddit, then LinkedIn, then AlternativeTo, then Privacy Guides, then HN) was the right call for a cold account. Each channel taught something about the audience before the next one. The Reddit posts I posted on were the best rehearsal for the harder threads because the sceptics asked questions I wasn't prepared to answer.
demo mode (/demo, no signup) outperformed the signup flow in early traffic. More people explored the product without signing up than with. That's fine; the demo is indeed the product.
Happy to take questions on the business model, the staged-launch approach, the encryption design, or the choice not to build for automatic bank sync!

Quantive (usequantive.app) is a net worth tracker built around two constraints: no bank connections, and the server never holds anything readable.
The audience is people who already track net worth manually ( in a spreadsheet, typically) and want something more structured without handing a third party access to their accounts. Manual entry is a feature, not a limitation. No Plaid, no Tink, no PSD2 provider, no aggregator in the chain. You enter balances or upload an Excel export from your bank, and that is the entire trust surface.
On the privacy side: your portfolio is encrypted in your browser before it reaches the server. The server stores ciphertext only. The crypto module is open source under MIT with a public design doc and test vectors. Everything else is source-available, for transparency.
13 currencies (EUR, USD, GBP, NOK, SEK, DKK, CHF, CAD, AUD, JPY, PLN, BRL, INR) with historically correct FX. Every balance snapshot is valued at the exchange rate from its own date (stored daily from ECB reference data - not at today's rate). This is the feature that keeps coming up with users who track across currencies over years: many multi-currency trackers silently rewrite history every time rates change.
What it doesn't do: connect to banks, categorise transactions, budget, handle tax-account-type logic, or defend against an actively malicious server. That last non-goal is the fundamental JS-delivery trade-off of all browser-E2E apps; it's documented in the design doc, not hidden.
As for the project, it is Bootstrapped and solo, legally registered in Germany. The addressable audience is small on purpose: people who track net worth manually over years and will pay €9/month for a tool that's better than a spreadsheet at this specific job. Not chasing venture scale, paid acquisition, or feature breadth.
About
I built Quantive because I tracked my net worth in a spreadsheet for years and got tired of maintaining it across accounts and currencies. Every existing app was either too complex or wanted my bank details.

The positioning shift is the part that stood out to me. You didn't change the product—you changed the reason people cared enough to try it. "Replace your spreadsheet" is an immediate pain people recognize. Privacy is what earns their trust after they're already interested. That's a subtle distinction, but it often makes all the difference.
Indeed, the time saved was the premise and the privacy aspect was just the differentiator, not the other way around.
Thank you for your insights, @Aryan!
Glad it resonated.
I actually have one more observation about that positioning shift that I don't think fits well in a public thread because it's more about the strategic decision behind the messaging than the messaging itself.
If you're interested, what's the best email to reach you on?
I don't mind - I'm fully transparent here, as my journey might also help other founders. Thank you!
Fair enough.
The observation is that changing the message also changes what success teaches you.
If people adopt the product because it replaces spreadsheets, future product decisions will naturally reinforce that interpretation. If the bigger opportunity is something else, execution can quietly lock you into one direction before you ever question it.
That distinction is what I found interesting.
