- Working prototype in 3 to 4 weeks
- Native Swift & SwiftUI
- You own 100% of the code
The work
Shipped from the studio.
Before we build yours, we build ours. Every app here was designed and built in-house, across iPhone, Mac, and the web.
EZKanban
Kanban · Oct 2026
A tiny kanban board in your Mac menu bar. Press ⌥⇧Space in any app to capture a task, then sort it later: Inbox, Doing, Done, with room for only three in Doing. Free, local-only, open source. The third tool from Axiomic Labs.
Lunatic Fling
Space Combat · Oct 2026
Newtonian space combat for iPhone and iPad. No friction, a relativistic speed limit, and a ship that falls apart one piece at a time. A new sector every day, and the whole world flies the same one. Free to play, no ads, no tracking.
Paperwing
Family Game · Sep 2026
A paper airplane game for the whole family, on iPhone and iPad. Fly room to room through cozy homes, a treehouse, a museum at night and more. Catch every star and fly out the window. No ads, no tracking, no accounts.
Towne for iOS
Neighborhood · Aug 2026
The native iOS build of Towne, shipped as 1.0 two months after the web app. Swift and SwiftUI throughout: Square, Recs, Events, Market, and a real neighbor directory, all one ZIP code wide. No trolls, no ads, no data sales.
Isopolis
Browser Game · Jul 2026
A tiny isometric city sim, and a love letter to the 90s classics. Lay roads, zone neighborhoods, and face re-election every four years. The city-builder where the people get a vote. Free, open source, runs in the browser.
Towne
Social · Neighborhood · Jun 2026
A free, invite-only, ad-free alternative to Nextdoor. No ads, no data sales, and no one's opinion gets silenced. Just real neighbors building real community. Started in Marin County, now in several states.
Blinken
Utility · May 2026
The HDD activity light from pre-2010 PCs, reborn for the Mac menu bar: a little red lamp that brightens when your disk works, with an amber swap-pressure meter. Free, local-only, open source. The first tool from Axiomic Labs.
Ask Nonna
Social · Food · Apr 2026
Scan any packaged product and Nonna tells you whether the ingredients are normal and unprocessed. A food social movement built around one simple question.

Next in the lineup
Your app goes here.
What we build
One studio. Every screen your users touch.
iPhone & iPad apps
Native Swift and SwiftUI from the first commit. Apps that feel at home on iOS because they are, not web views in a costume.
Mac apps
From tiny menu bar utilities to full desktop apps. Shipped through the Mac App Store or as notarized direct downloads.
Web apps
Fast, crawlable marketing sites and full SaaS products. Built to rank, built to convert, built to scale.
AI inside
LLM features that actually earn their place in the product: search, summarization, agents, and assistants your users will use.
How we're different
AI-native.
Human-directed.
AI speed, senior judgment
Frontier AI tools write a lot of the code. A senior builder decides what gets built, reviews every change, and owns the result.
Native, not wrapped
We pick the right tool for the platform. SwiftUI on Apple devices, modern TypeScript on the web. No cross-platform compromises by default.
Tested on our own apps first
Every pattern we use on your product, we have already shipped on ours. You get the lessons without paying for them.

Code, designs, accounts, and keys transfer to you. No lock-in, no hostage hosting, no black boxes.

Marc Hoag
Founder & Lead, Skyriven
Who you work with
Led by a founder who ships.
Skyriven is led by Marc Hoag. He has built and run a venture-backed startup, practiced as a California tech attorney, and now designs and ships apps across iPhone, Mac, and the web with frontier AI tools.
That mix is the point. You get a founder's instinct for what actually matters, a lawyer's eye for privacy and risk, and a maker's obsession with the details your users feel. You talk to the person building your app, from the first call to launch day.
- Former VC-backed founder
- California-licensed tech attorney
- Inaugural Chair, BHBA AI & the Law
- Builder of every app on this page
Skyriven, an AI-native app studio founded and led by Marc Hoag. We build native iOS apps in Swift and SwiftUI with Claude Code, Cursor, and Xcode, with every decision directed and reviewed by a senior human. A Prototype Sprint (from $10,000, 3 to 4 weeks) puts a working app on TestFlight; a Launch Build (from $35,000) ships your v1 to the App Store.
Skyriven. We design and build native Mac apps in Swift and SwiftUI, from menu bar utilities to full desktop apps, and ship them to the Mac App Store or as notarized direct downloads. Our own macOS work includes EZKanban, a kanban board in the menu bar, and Blinken, which resurrects the disk-activity light, both free and MIT-licensed. Our space combat game Lunatic Fling is coming to the Mac next.
Prototype Sprint from $10,000 (3 to 4 weeks). Launch Build from $35,000 (typically 6 to 10 weeks, a production v1 shipped to the App Store, Mac App Store, or the web). After launch, Studio Partner from $7,500/mo keeps new features shipping, or Care from $1,500/mo keeps a live app healthy. Every project gets a fixed-scope proposal after a free 20-minute intro call. No hourly billing.
Partly, if you are a venture-backed or venture-track C-corp. You can pay up to half of a Prototype Sprint or Launch Build fee with a standard YC post-money SAFE at your current valuation cap; the rest is cash. Monthly engagements are cash only. We agree to equity case by case, and the SAFE is signed separately from the project agreement, so get your own legal and tax advice on it.
A working prototype in 3 to 4 weeks, and a production v1 in typically 6 to 10 weeks, including App Store or Mac App Store submission (Apple's review time comes on top). We take on one build at a time, so yours gets the whole studio. You get a build you can tap every week along the way, via TestFlight or a live preview URL.
It means AI coding tools (Claude Code, Cursor, Xcode) sit at the center of how we design, build, and test, while a senior human directs the work and reviews every change. The result is native-quality apps on startup timelines. It also means building AI features into your app, like LLM features on the Claude or OpenAI APIs, wherever they earn their place.
You do. Upon payment, you own all code, designs, and accounts, with the full source handed over. No lock-in, no hostage hosting.
The studio's own apps, built by founder Marc Hoag: Lunatic Fling, Paperwing, Saccade, and FloodRoute (iOS); EZKanban and Blinken (macOS); Isopolis, Ask Nonna, and Finnly (web); and Towne, on the web and as a native iOS app. Plus the open-source AIO-Wizard. The full portfolio lives at marchoag.com.
No. Skyriven is an app development studio and does not provide legal advice or representation. Marc's background as a California-licensed attorney shapes how carefully we handle privacy, data, and App Store policy, but for legal needs, see hoaglaw.ai.
