OUR STORY

I'm building Buoy in the open. The way your money is handled isn't up for debate.

Buoy is an early-stage personal-finance app built around count-up budgeting: your categories earn a daily allowance that grows when you underspend. It's newly live on Google Play with iOS on the way, I'm building in public, and founding members help shape the features and the roadmap. What I did NOT leave for later is security. Your bank connects through Plaid, read-only, so Buoy can never move your money and never sees your bank login.

Why I'm telling you it's early

Most startups wait until everything looks finished before they say a word. I'd rather do the opposite. Buoy is early. Newly launched, still taking shape. I think the honest version of that is also the more interesting one. When you join now, you're not a late arrival to a polished machine. You're early enough to change what gets built.

That's a deliberate choice, and it cuts both ways. There are two kinds of "early," and I want to be precise about which one I mean.

Two lanes, and I never mix them up

The product is early. The safety of your data is not.

The product is genuinely open: the count-up mechanics, the badges, the categories, the AI advisor's tone, what I build next. I don't have all the answers, and I don't pretend to. I'd rather build the next features with the people who'll use them than guess in a room by myself. That's the part I'm inviting you into.

The way your financial data is handled is a different lane entirely. That was architected from the first line of code. It isn't a work in progress, an "I'll harden it later," or anything I'd ever put to a vote. A budgeting app is only worth using if the money side is boringly, unshakably safe. So here's exactly how it works, in plain English.

How Buoy connects to your bank

When you link an account, you do it through Plaid, the same connection layer behind apps like Venmo, Robinhood, and Coinbase, used by thousands of banks and finance apps. Three things follow from that, and all three are true by design:

  • Read-only. Buoy can see balances and transactions so it can build your budget. It cannot move money, make a payment, or change anything in your accounts. There is no pathway for it to do so. That's not a policy, it's the architecture.
  • I never see your bank login. You type your credentials into Plaid's own screen, which hands them to your bank. They never touch Buoy. I receive an encrypted access token, not your username and password.
  • Encrypted in transit and at rest. Your data is encrypted on the way to my servers and while I store it. You can disconnect any institution at any time, and that cuts off access immediately.

And one more, because it shapes everything else: I make money from subscriptions, not from your data. You are the customer, not the product. I don't sell or share your financial information. The Privacy Policy spells out the specifics, and my marketing will never say anything the policy doesn't back up.

What "building in the open" actually means here

Concretely, here's what I'm putting in place, not just a vibe:

  • A public roadmap where founding members can see what's coming and vote on what matters most: the next badges, new category types, count-up tweaks.
  • A "You asked, I shipped" changelog that closes the loop. When something you suggested goes live, you hear about it, and I say who asked for it.
  • Founding-member access for early users: early access to new features and a real say in the direction. It's about access and influence first; I'm shaping the rest with you.

What it does not mean: I will never publish vanity numbers I don't have, never imply a feature exists before it does, and never ask the internet to help me "figure out" how to protect your data. Build-in-public, for me, is about product decisions, never about safety.

Come build it with me

If count-up budgeting sounds like the thing you wished existed, and being early sounds like a feature rather than a risk, this is the moment to get in. Tell me the budgeting problem you're actually trying to solve when you sign up. That's not a marketing question. It's the first thing that'll shape what I build.

I'm early. I'm not careless. Come help me shape what's next.

From the founder

Hi, I’m Jonathan, and I’m building Buoy. By day I’m a Senior Software Engineer at a large, publicly traded security company, working on AI agent systems in C#, Kubernetes, and Python. Nights and weekends, I build Buoy solo, full-stack: the architecture, the product, all of it.

My route here was unusual: I started out as a molecular biologist. During COVID-19, as a frontline microbiologist at the Kansas Department of Health & Environment, I taught myself to code and built a data pipeline that saved analysts hundreds of hours a week and helped push Kansas to top-3 in the country for sequencing turnaround. Handling sensitive data carefully isn’t new to me. It’s exactly why Buoy’s security was architected from day one, not bolted on later.

That’s how I work: spot the improvement, build it, bring people along. Buoy is me doing that for personal finance, and I’d genuinely love your help shaping it. (Off the clock: husband, dad of two, happiest outdoors or tinkering with something.)
