Case Studies

Architecture, customers,
real numbers.

Three published case studies. Every metric is sourced from the product repository or a named live customer. No invented growth charts, no inflated deployments.

What is the KaritKarma case studies index

A short, honest reference for how products ship on this platform.

The KaritKarma case studies index lists every product whose architecture and customer status we are prepared to defend in a technical briefing. Three studies are published today: Sotto for AI voice ordering, NewsForge for autonomous newsroom operations, and Kuhok for the dignity-first film network.

Each case study is grounded in the product repository at the date of publication. Live-customer claims are named only with permission, pilot and production-ready states are labelled separately from named-live states, and superseded claims are corrected rather than quietly kept. If a metric is dated, it carries the date.

The three studies

One platform. Three very different products.

What we do not publish

Honesty bar for case studies.

We refuse a few categories of claim that have become standard in SaaS marketing. Each one is here so a buyer knows what to expect (and what to verify) before signing.

Architecture diagrams sourced from the live repository
Instead of: Architecture diagrams drawn for the case study with no code reference
Test counts and microservice counts taken from the source tree on a dated commit
Instead of: Round-number metrics with no traceable source
Named customers only with written permission
Instead of: Anonymous logos or stock-image customer collages
Latency budgets with stage-by-stage breakdown
Instead of: Latency claims with no stage attribution
Pilot, beta, and production-ready states labelled separately
Instead of: Pilot deployments cited as production wins

Frequently asked

Case studies, asked plainly.

Six answers we have written down so a briefing call does not spend ten minutes on definitions.

What case studies does KaritKarma publish?
KaritKarma publishes three technical case studies that cover three different verticals. (1) Sotto, the AI voice ordering platform for UK restaurants, runs on .NET 10, Groq Llama 4 Scout, Whisper Large v3 Turbo, and Deepgram Aura 2, engineered to a sub-500 millisecond time-to-first-audio budget. (2) NewsForge, the AI synthesis newsroom, is an all-Go platform (Go 1.26, PostgreSQL 18 with pgvector, NATS JetStream) that clusters multi-source coverage, synthesizes one original article per story, and publishes to 10 CMS and social channels after human editorial approval. (3) Kuhok, the dignity-first network for cast and crew, runs 14 .NET microservices behind a YARP gateway with Darwan RBAC enforced per route and is live at kuhok.net. Each case study documents the architecture, the integrations, and the shipped customer status.
Are KaritKarma case study customers real production deployments?
Customer status varies and we label each case honestly. Kuhok is live at kuhok.net. NewsForge's first generation ran the Bengali-first portal khoboria.com as its founding deployment; the platform has since been rebuilt as an all-Go stack, deployed at newsforge.news, with first-tenant onboarding in progress, so we do not present khoboria as a current-stack customer. Sotto is built and tested as a production-ready platform with 609 unit tests and a sub-500 millisecond latency budget, in the UK restaurant pilot stage. We do not promote pilot deployments to general availability claims and we name customers only with explicit permission.
Which KaritKarma platform services do the case study products integrate?
The integration surface differs per product, and we state it exactly. Kuhok integrates Wenme for OAuth sign-in through a dedicated identity adapter, Darwan for route-level authorization across its services, and a bidirectional Rating BD bridge for talent verification. NewsForge validates Wenme-issued OAuth 2.1 JWTs, authorizes through Darwan, and ships a media client built to store assets by reference in Foveio, KaritKarma's media layer, with per-channel renditions (live as Foveio launches). Sotto intentionally ships self-contained for its UK market: its own NextAuth and JWT auth, Stripe payments, Twilio voice and SMS, Groq and Deepgram AI, with no KaritKarma platform-service dependency. We publish that difference rather than papering over it.
How long does it take to ship a product on the KaritKarma platform?
Platform reuse is the lever where it applies. Kuhok shipped 14 microservices behind a YARP gateway with a Next.js 16 frontend by inheriting Wenme identity and Darwan route authorization instead of building them. Sotto was engineered to a sub-500 millisecond voice budget on .NET 10 with 29 projects in a Clean Architecture monorepo. NewsForge's all-Go rebuild ships 8 services with 848 Go test functions, a synthesize-once, localize-on-demand pipeline, and 10 publishing connectors registered at boot.
Can I see the source data behind a case study claim?
Yes. Every numerical claim on a case study page (test counts, microservice counts, latency budgets, connector counts) is sourced from the product repository at the date of publication. Counts that depend on a live system (uptime, customer counts, publish volumes) are dated and are refreshed when we update the case. If you need a verifiable reference before signing a contract, we walk the architecture and the relevant repository views in a 30-minute technical briefing.
Where do KaritKarma case study products run?
All KaritKarma-operated infrastructure runs on hardware physically owned inside Bangladesh, in a Tier-3 data center on AS 64005 as an APNIC member. Sotto, as a UK restaurant product, deploys in a UK-region envelope for data-residency reasons. NewsForge runs on KaritKarma infrastructure at newsforge.news. Kuhok runs on KaritKarma infrastructure and serves kuhok.net.
