CASE STUDY · CLOUDBOOK · 2026

A consumer product,
shipped in two weeks.

cloudbook is a virtual sports-betting platform — real odds, real games, fake money, real reputation. cloudgroup built it to test our own thesis: ambitious consumer products are now buildable in days, not quarters. Two weeks to first launch, 100+ versions since.

BUILT
A virtual sports-betting platform with web + iOS apps, eight leagues, group competition, and AI agents that bet on your behalf.
NUMBERS
3,075+ games offered · 2,852 bets graded · $977K virtual wagered · 5,663 agent decisions · 100+ shipped versions.
TAKEAWAY
“Bet your reputation. Keep your money.”
01

The thesis: ambitious consumer products belong in this studio too.

cloudgroup's core promise is that custom software is finally within reach — fixed-price, two-week sprints, full code ownership. The early proof points were operational: internal tools, admin systems, the kind of work non-technical founders had been priced out of for years.

But the bigger question loomed: does this approach work for an ambitious consumer product? Real-time data, polished mobile, social mechanics, a multi-platform launch — the kind of thing that used to require a venture round and twelve months. We wanted to know if the new toolset could compress that, too.

cloudbook was the answer to our own question. We picked a category we love (sports), a real frustration (most fans want the engagement of betting without the financial risk), and we built it the same way we build for clients: scope first, design second, ship fast.

“A two-week project that grew into the most-iterated thing we've ever shipped.”

Architecture: three layers, real markets in, reputation out.

The hardest design choice was getting the foundation right. Most fantasy products invent their own scoring; we wanted to anchor cloudbook in real sportsbook lines so that every prediction was honest. That meant building three layers, each doing one thing well:

CLOUDBOOK STACK · 3 LAYERS
L1
Real markets
Live odds and final scores from professional sportsbooks across nine leagues, refreshed automatically. Closing-line value (CLV) is captured at game start so we can score how good your line was, not just whether you won.
L2
Verifiable track record
Bets are graded against real game outcomes the moment they finish. Win rate, ROI, line-value, and personal records compound into a credibility tier — Bronze, Silver, Gold — that's impossible to fake because the games actually happened.
L3
Social + AI competition
Leagues for group competition with a Sunday salary system, a global leaderboard ranked by ROI, custom AI betting agents that run their own strategies, and follow / feed mechanics on top.
OUTPUT → a public, verifiable sports-prediction track record. Reputation is the product.

The dashboard fuses the three layers — career stats, this week's performance, leagues, and your agents — into one home view.

What we built.

Four interlocking products, all in one platform:

  • Cross-platform shell
    A Next.js web app and a native iOS app (Capacitor) sharing one codebase. Sign in once, place a bet on the train, check it again at home.
  • All major sports
    NBA, NCAAB, MLB, NHL, EPL, EFL Championship, MLS — live now. NFL and NCAAF light up when their seasons start. Spreads, totals, moneylines on every game.
  • Leagues
    Private or public groups with weekly bet requirements, league-scoped balances, ROI-based standings, and Sunday paydays. The social layer that turns a solo habit into a multiplayer game.
  • AI agents
    Custom betting agents — each user can deploy one with a written strategy. The platform fields six house agents that run 24/7, logging every decision (bet or pass) with reasoning.

Beyond the numbers: cloudbook ships to production every couple of days. The same approach that ships a client's build in two weeks lets us push twenty improvements per month to our own product. Features that used to require a roadmap meeting — agent caching, ROI callouts, decision-journal scrolling — get spec'd, built, and deployed in an afternoon.

Economics.

THE NUMBER THAT MATTERS

A consumer product, built and launched, for the cost of a single Medium engagement.

cloudbook would have been a Medium engagement at cloudgroup pricing — $40K, four weeks, multi-feature product. We built it for ourselves to prove the math, then kept iterating because we like the product. The takeaway for clients: ambitious consumer ideas — the kind that used to need a seed round — fit inside a fixed-price engagement now.

How it felt.

“We built the product we wanted to use ourselves — and shipped a hundred versions of it before half our peers shipped one.”

— Mark Brogowicz, cloudgroup
