Publishers hand over content. Platforms hand back a royalty report.
The dominant digital channels strip out the reader relationship, withhold engagement data, and take a cut of every sale — indefinitely. The alternative — a bespoke custom build — costs six figures and twelve to eighteen months. Neither is good enough.

Publish360 is the third option.
A production-ready platform. Publisher-branded. Direct to reader. No commission, no custom build, no surrendering your audience to someone else's platform.
Already live. Already serving readers. Ready for your brand.
Publish360 is a production platform that independent publishers configure and brand as their own. When you join, you benefit from the investment already made in the eBook reader, audiobook player, DRM integration, offline architecture, and analytics engine — rather than paying to build it from scratch.
The distinction matters: a bespoke build creates technical debt and requires ongoing maintenance funding. The Publish360 platform licence includes everything your platform needs to stay current, compliant, and performant.
18–22 weeks to launch
The platform is already built, tested, and serving publishers. Configuration, branding, and integration — not months of architecture work.
Fixed setup fee
One agreed cost covers everything from discovery to live app store submission. No day-rate overruns, no change order risk within scope.
Maintenance included
iOS and Android updates, security patching, DRM management, CDN and hosting — all covered in the platform licence. No developer retainer needed.
See your app before you pay for anything
Eden Interactive will build a working demo of your branded app — populated with a sample of your actual catalogue, applying your branding — before any commercial agreement is signed. You see your app, in your colours, with your content, on your phone. If it is not what you expected, you walk away without having paid anything.
Your catalogue
Demo built from your actual titles and cover art — not placeholder content.
Your brand
Your logo, your colour scheme, your app name on the store listing.
Zero commitment
No contract. No deposit. Walk away if it is not right for you.
One app. Every format your readers need.
Most competing platforms specialise in a single format. Publish360 handles eBooks, audiobooks, video, and courses in a single branded app — and readers never need to think about which format they are using.
EPUB & PDF
Reflowable and fixed-layout EPUB, plus high-fidelity PDF — in a single unified reader. Adjustable font, night mode, full-text search, bookmarks, and offline download.
Readium LCP DRM included
Download-first audio
A first-class listening experience with variable speed, sleep timer, chapter navigation, and background playback. Download-first architecture guarantees uninterrupted listening anywhere.
AES-256 encrypted storage
Author events & courses
Conference recordings, author Q&As, instructional content, and book launches — all within the same app experience. Delivered via CDN with transparent monthly allowances.
Streaming & download delivery
Structured learning
Modules, guided pathways, quizzes, flashcards with spaced repetition, and progress tracking — for publishers with professional development, academic, or training content.
Add-on module, scoped per client
Technology that gets out of the way and lets readers read
The eBook reader and audiobook player are the core of the platform. Both are designed to be invisible — professional-grade features without the friction. eBooks and audiobooks appear together in a single My Library — cover art, progress, and download status visible at a glance.

Offline-first architecture across iOS, Android, and web
Content downloads to device. Notes sync when connectivity returns. Configurable device limits (typically three) reduce account sharing.
Protection that readers never see. Security that content always has.
Publish360 uses Readium LCP — the industry standard for EPUB DRM, developed by EDRLab to replace the friction and failure modes of Adobe Digital Editions. If your readers have ever struggled with DRM before, this is the technology built specifically to solve that.
Audiobook files are encrypted at rest with signed URLs that expire after use. Supplementary materials use social DRM — a watermark containing the purchaser's identity — a proportionate deterrent for clinical and professional content that must remain editable.
Invisible to legitimate readers
Readers open their purchase on their phone, tablet, or the web — without knowing any protection is in place. Files are locked to their account and device, making extracted copies non-functional outside the app.
Works fully offline
Downloaded eBooks are protected and readable without connectivity. No separate account or device authorisation step required — a reader clicks their title and it opens.
No device registration
Unlike Adobe Digital Editions, Readium LCP requires no frustrating device authorisation steps that created support overhead and damaged customer relationships.
Open, interoperable standard
Developed and audited by EDRLab — the non-profit digital publishing consortium. Eden Interactive is an EDRLab member. LCP is not locked to any single vendor.
No revenue share. Sell your way.
Publish360 is built around a publisher-first commercial model: sell through your own ecommerce infrastructure and keep the full margin. There is no commission on sales made through your website — no cut going to Apple, Google, or Eden Interactive.
Reader app model (recommended)
All purchases made on your website, using your payment processing. The app is free to download. When a reader buys, a webhook communicates the entitlement to Publish360 and the content appears immediately in their library.
In-app purchases
Purchases processed inside the app via Apple or Google. Subject to 15–30% platform commission depending on your revenue level. Can run in parallel with the website purchase model.
Subscription tiers
Recurring subscriptions with access to full catalogue or defined collections. Trial periods, promotional codes, and coupon-based access all supported.
Works with your existing ecommerce
Publishers do not need to replace their current commerce infrastructure. Eden provides a documented REST API and webhook schema that integrates with whatever you already operate.
Marketplaces sell your books. Publish360 tells you how readers use them.
On Amazon, you know how many copies sold. On Publish360, you know which chapter 32% of your clinical readers abandoned — and you can use that to improve the next edition. The analytics dashboard is built into the publisher admin hub, with no additional licence or third-party tool required.
A marketplace gives you
- Number of copies sold
- Royalty payment
- Nothing else
Publish360 gives you
- Which chapters readers abandon
- Average time spent per title
- Which purchases were never opened
- New vs. returning reader trends

A third option — between the marketplace and the custom build
| Dimension | Major marketplace | Custom build | Publish360 |
|---|---|---|---|
| Commission on sales | 15–70% | None | None |
| Time to market | Immediate listing | 12–18 months | 18–22 weeks |
| Reader relationship | Owned by platform | Publisher's | Publisher's |
| Reader data & analytics | Royalty report only | If built | Full, chapter-level |
| Cost structure | % per sale, forever | Open-ended build cost | Fixed setup fee |
| DRM included | N/A | Requires integration | Readium LCP included |
| Ongoing maintenance | Platform's | Publisher-funded | Included in licence |
| Branding | Marketplace brand | Publisher's | Publisher's |
Publish360 does not replace marketplace distribution — publishers can sell through both simultaneously. It adds a direct channel the publisher controls.
Built for publishers of every kind
You have built a catalogue. Stop watching 30% disappear.
You sell through Amazon and other marketplaces and watch the margin vanish. You have no idea how your readers engage with your content. Publish360 gives you a direct channel, operational in under six months, with analytics that tell you more about your readers than any marketplace ever will.
Fillable forms, institutional SSO, and chapter-level analytics.
Your catalogue includes clinical resources, academic textbooks, or professional training content. The standard marketplace experience is too generic. Publish360 is designed for this: DRM that works seamlessly for professionals, supplementary materials in the same app, SAML for institutional buyers.
eBooks, audiobooks, video, and structured courses — one app.
Your content includes video, guided pathways, and quizzes alongside or instead of traditional books. Publish360 handles multiple formats, tracks learner progress, and integrates with your existing ecommerce or LMS infrastructure.
Arabic, Chinese, Korean, Thai, Indonesian — and offline for variable connectivity.
Your content serves readers across languages and regions. Publish360 handles RTL scripts correctly, supports localised interfaces, works offline in markets with patchy connectivity, and allows regional availability control from the admin hub.
Migrate to a sustainable platform without losing your reader base.
Custom-built apps have a lifespan. Architecture becomes dated, agencies move on, and iOS/Android maintenance costs grow every year. Publish360 supports migration of existing user accounts, purchase history, and entitlements as part of implementation.
Reach your audience directly with accessible, affordable distribution.
Charitable organisations with publications, training resources, or pastoral content can use Publish360 to distribute directly to their communities — with the same professional DRM, analytics, and accessibility compliance as any commercial publisher.
