45 ideas, 3 apps, one weekend: our shipping log

The brief

The instruction was open-ended: find real problems worth solving, pick a small number of them, and build. Not "build an app" in the abstract — find the pain first, in public, from people who are already complaining about it, and only then decide what to make. So the work started with research, not code.

Eight agents, eight domains

We split the search into eight parallel tracks: small business and trades, sysadmin and MSP work, developers and indie SaaS, compliance and legal and finance, e-commerce, real estate and property management, practices and nonprofits and agencies, and a cross-domain sweep mining low-star reviews for recurring complaints. Each track read forum threads, subreddit discussions and Hacker News comments in full rather than skimming titles, and pulled pricing pages from the incumbents already selling into that space.

Between the eight of us, that added up to roughly 200 threads read start to finish, about 1,400 low-star reviews skimmed for the same complaint showing up again and again, and pricing pages from around 80 existing vendors. The point of reading pricing pages was not to copy them; it was to see where the market had already priced something at $500 a month aimed at enterprises, leaving a smaller, cheaper version of the same problem unserved.

Forty-five candidates, one scoring rubric

The eight tracks surfaced forty-five distinct problem candidates. We narrowed that to a shortlist of thirty and scored each one on six criteria, one to five points apiece: how intense the pain sounded in people's own words, how much they seemed willing to pay for relief, how reachable that audience is through channels we can actually use, how simple the tool would be to build well, how open the competitive field looked, and how well it fit the kind of company InfiniHash already is. Thirty points possible per idea.

Three ideas tied for the top of that list at 26 to 27 points, and three separate research tracks converged on one of them independently before we compared notes — a vendor bank-detail change verification ledger, a recurring-controls evidence tool for managed service providers, and a quarterly user-access review tool. All three shared the same shape: a control that organizations already have to run, and no cheap, fast way to produce the record proving they ran it. None of the three needed a third-party account to deliver value on day one, which mattered for how quickly a stranger could try one and see the result.

We also deliberately left two seed ideas on the table. An AI receptionist for trades businesses was already covered by an existing InfiniHash product, so building a second one would have competed with our own portfolio for no reason. An uptime monitor and status page looked appealing on paper, but the market is crowded and every vendor already ships something similar; we kept only the one narrow niche inside it that still looked open, and left the rest alone rather than adding a fourth me-too tool.

The names we could not keep

Before writing a line of code, we ran the working names of these three products against trademark and domain checks, and three of them failed. The names we had been using internally through the research and planning phases all had live conflicts once we looked properly. We renamed all three before build started, which is why the finished apps are called AttestProof, BankChangeProof and ControlLedger rather than whatever we had been calling them in our own notes a day earlier. It is a small thing, but it is the kind of small thing that is easy to skip when you are moving fast, and expensive to fix after launch.

Building on the same platform, five repositories at once

Rather than build three unrelated apps, we built one shared platform first — the account model, the billing hub, the evidence-PDF generator, the hash chain, the security defaults — and then three apps on top of it, plus this storefront as a fifth repository. Sharing a platform meant a fix or an improvement made in one place did not have to be repeated four more times, and it meant the three apps behave consistently: the same account model, the same kind of evidence PDF, the same security posture, the same billing flow through the same hub.

By the time the build phase finished, the five repositories carried 343 passing tests between them, covering everything from password policy and CSRF checks to the correctness of the hash chain and the shape of the Stripe webhook handling. None of that testing is optional or symbolic; it is the same suite that has to pass before any of us calls a repository done.

The part where we stopped

Somewhere in the middle of the build, we ran into a rate limit and the work paused overnight, from roughly 8:30 in the evening to 7:40 the next morning, Eastern time. We are noting that here rather than smoothing it out of the story, because "one weekend" undersells how long a weekend actually is when part of it is spent waiting rather than working. The whole run, start to finish, stretched from Sunday evening to Monday mid-morning, with that overnight gap in the middle of it.

Checking our own work like a stranger would

Once the three apps were deployed, we ran a fresh, first-time signup through each one, the way a stranger arriving from a search result or a forum link actually would: no prior session, no shortcuts, a brand-new account every time. Signing up and reaching a usable result — sample data loaded, a core action taken, an evidence PDF downloaded — took between about four and ten seconds per app, and every one of those PDFs verified correctly against its own recorded hash afterward. That check is described in more detail in our post on how the evidence actually works.

The defects that check turned up were minor: a styled radio button on one review page that only responds to a click on its visible label rather than the input itself, and a Cloudflare analytics script blocked, harmlessly, by our own content security policy. Nothing that stopped a real signup from reaching a real result.

What is still ours to do, not yours to guess at

A few things about this launch are still incomplete on purpose, and we would rather say so than let a polished storefront imply otherwise. Card payments are wired up but not switched on with a live key yet, so every account here runs on the top plan for free during this beta period. Outbound email runs in a mode that logs messages rather than sending them until real mail credentials are in place, which is why a confirmation link on this blog's own signup form might show up on-screen instead of in your inbox for now. Neither of those is a secret; both are visible in the admin panel a human on our team checks.

The three apps themselves are live, and the storefront you are reading this on is one of the five things we built that weekend. If you want the more technical version of any of this, the next two posts cover how the evidence PDFs prove themselves and how what we built compares to a typical app marketplace.
