Commitments
Three things we commit to. In writing.
Not marketing. Contractual promises written into our quotes.
Clean, documented, 100% transferable code.
On delivery, you get everything: commented source code, Postgres schemas, architecture diagrams, runbooks. If you switch providers tomorrow, your new team will be productive within 48 hours.
No bullshit. We report in plain language.
Weekly demos. No slide decks, no jargon. You see the code running, you understand where every euro goes. If we're behind, we say so the week it happens — not at delivery.
1-month post-launch warranty included.
Any bug introduced before delivery is fixed at no extra cost for 30 days after going live. No ticket, no support queue: we respond within 48 hours.
Technical challenges
Where complexity sets us apart.
Four real problems we solved in production. Not buzzwords — shipped code.
AI · LLM
Multi-model LLM pipeline
On Meduz, a pipeline orchestrating multiple models (one narrative, one instruction-tuned) with dynamic routing based on conversational context. Sub-second latency, controlled costs.
const pipeline = {
narrative: 'llama-3.1-70b',
instruct: 'gpt-4o-mini',
router: context-aware
};
narrative: 'llama-3.1-70b',
instruct: 'gpt-4o-mini',
router: context-aware
};
Hardware · BLE
Native Swift + Kotlin plugins for real-time BLE
On Meduz, integration of a Bluetooth Low Energy hardware device with native plugins built in Swift (iOS) and Kotlin (Android), exposed to Flutter via method channels. Real-time streaming, fine-grained battery and reconnection handling.
channel.invokeMethod('startScan', {
serviceUuid: 0xFE12,
notify: (bytes) => stream.add(bytes)
});
serviceUuid: 0xFE12,
notify: (bytes) => stream.add(bytes)
});
Streaming · Live
Sub-3s live streaming at controlled cost
On Blisterr, live streaming with sub-3s latency. Hybrid architecture: LL-HLS for viewers, WebRTC for co-streamers. On-demand infrastructure that scales with load and keeps costs under control.
const player = {
protocol: 'll-hls',
latency: '< 3s',
fallback: webrtc
};
protocol: 'll-hls',
latency: '< 3s',
fallback: webrtc
};
Cloud · AWS
Multi-AZ AWS infrastructure for 50 student associations
On Vibly, multi-AZ AWS architecture supporting 50 student associations with their own feeds, paid events, and real-time chats. Express and MongoDB on Elastic Beanstalk, S3 for media, Firebase for notifications.
aws.rds({
engine: 'aurora-postgresql',
multiAz: true,

Live auction marketplace
Blisterr
Live auction marketplace for collectibles: the seller runs a livestream, buyers bid in real time on each lot. We took over the existing Flutter app and backend to ship a faster version, built on a hybrid LL-HLS + LiveKit streaming architecture and a broadcast infrastructure provisioned on demand, sized live by live.

Frequently asked
What clients ask before they sign.
The answers we give in discovery calls. Plain English.
What budget should I plan for a project with Black Tide Studio?
Our reference ranges are €12k to €25k ex VAT for a prototype, €35k to €70k ex VAT for an MVP and €80k to €160k ex VAT for a scalable product. These are not packages: scope, technical risks and the level of support determine the quote after scoping.
How long does it take to build a mobile app?
Timing depends on scope, external dependencies and the risks that need to be resolved. Technical scoping produces a realistic schedule with explicit milestones and trade-offs before the build starts.
Native (Swift/Kotlin) or cross-platform (Flutter/React Native), which to choose?
Flutter or React Native share a substantial part of the product across iOS and Android. Native Swift and Kotlin provide direct control over each platform. The choice depends on the expected experience, hardware integrations, performance constraints and the skills of the team that will own the product; we make it during scoping.
How should I choose between Black Tide Studio and a freelancer?
Black Tide brings product design, development, cloud architecture, testing, deployment and follow-up into one engagement. A freelancer can be especially well suited to a focused requirement or to strengthening an existing team. The right choice depends on scope, the responsibilities to cover and the organisation already in place.
Why a studio on Île d'Oléron instead of Paris?
Our published daily rate is €750 ex VAT. We work remotely from Île d'Oléron, with regular check-ins and travel when the project requires it. The quote sets out the scope, estimated days and any third-party costs.
How does budget estimation work?
Free 30-minute discovery call. If we're the right team, we run technical scoping (1 to 2 weeks billed at day rate). Output: detailed quote line by line, timeline, target architecture. No commitment before the signed quote. If we're not the right team, we point you to someone better suited.
Next step
Want us to look at your project?
