What Prototyp Stockholm AB does
Prototyp Stockholm AB is a privately held Stockholm-based code lab founded approximately 2009-2011, operating four offices across Sweden with a team of 11-50 employees. The firm sells senior-led digital product development services to three customer cohorts: startups (e.g., ClimateHero, PlayWellMinds, Mindmore), large enterprises (Matsmart, Stora Enso, ICA, Samsung, Microsoft), service design agencies (Antrop, Äventyret), and research/government institutes (RISE, Karolinska). Engagements are delivered by small cross-functional teams of 2-7 code experts, with an average client relationship length of approximately five years, and range from two-week AI PoCs and eight-week prototype-to-MVP builds to multi-month platform work.
The company operates across a broad technology surface spanning modern web (React, Next.js, Svelte 5, RedwoodJS), cross-platform mobile (Flutter, React Native, Xamarin), backend services (Node, GraphQL, Prisma, Supabase, Firebase, Firestore), headless CMS (Contentful, where it holds a leading extensions-development position), and AI/ML tooling (OpenAI, Anthropic Claude Code, Cursor, Whisper, ElevenLabs, LangChain, Pinecone, RAG). It has built proprietary AI assets including Taco.ai (an open-source group-chat AI tool on OpenAI) and Norimaki (a RAG platform for organizational knowledge bases), and publicly codifies its AI-augmented agile methodology in the Prototyp AI Playbook. Annual Prototyp Week hackathons generate public prototype labs (Birdhouse AI, Large Language Adventure, Sonos Voice Clone, FamiljeGPT, etc.) that double as brand and developer-relations assets.
Revenue is generated primarily through project-based professional services and embedded-team managed services billed on quote-based engagements; pricing is not publicly disclosed. Go-to-market is sales-led, with the CEO (Tobias Bard) and Business Director (Peter Shishoo) personally meeting prospects, supplemented by content marketing (AI Playbook, case studies, lab prototypes, newsletter) and community channels (LinkedIn, YouTube, GitHub, Teamtailer). No external funding, parent company, or revenue figures are disclosed; the firm is founder-influenced (co-founder Erik Lindgren is publicly identified) and privately held under the Swedish Aktiebolag designation.

Revenue model
- Project-based digital product development: Custom development engagements billed per project/sprint, ranging from short 8-week PoC builds (e.g., ClimateHero) to multi-month MVPs (e.g., PlayWellMinds, Signe) and longer-term platform work. Pricing is quote-based.
- Embedded senior development teams: Retainer-style engagement where senior code experts are embedded in client teams (e.g., one full-time Prototyp developer on ClimateHero for 8 weeks), functioning as an outsourced tech lead.
- Open-source / freemium product side-projects: Self-developed tools (Taco.ai) released as open-source on GitHub with potential for paid premium usage tiers. Not a primary revenue stream but a marketing/credibility asset.

Prototyp Stockholm AB product offering
Product offeringCore offering
Prototyp Stockholm AB is a code lab that builds digital products for businesses breaking new ground through a portfolio of custom development services — AI Proof of Concept, App Development (native/web/hybrid), Minimum Viable Product, Flutter Development, general Proof of Concept, Contentful Extensions, and User Interface Development — delivered by small senior teams of 2–7 code experts embedded with clients. The studio supplements services with two proprietary AI tools (Taco.ai, a shared group-chat AI; and Norimaki, a RAG-based internal AI agent platform) and a publicly documented AI Playbook methodology, applying a prototype-first, AI-augmented agile approach to engagements averaging about five years per client.
Product overview
Prototyp Stockholm AB is a Stockholm-based code lab offering a portfolio of digital product development services alongside proprietary AI tools and a published methodology. Their core offering is a set of seven consulting/development services — AI Proof of Concept, App Development, Minimum Viable Product, Flutter Development, general Proof of Concept, Contentful Extensions, and User Interface Development — typically delivered through small, senior agile teams in engagements averaging at least five years with each client. They complement these services with three internal AI products: Taco.ai (a group chat AI tool built on OpenAI) and Norimaki (an RAG-based internal AI agent platform), as well as The Prototyp AI Playbook, a public methodology guide that codifies how they integrate AI agents (Claude Code, Cursor, Linear via MCP, GitHub) into their agile workflow. The services and proprietary tools together form a unified 'prototype-as-methodology' platform, where Taco.ai and Norimaki are products the team uses internally and offers to clients, while the services represent the custom client delivery engine — often culminating in case-study products like ClimateHero (Svelte 5 + Supabase), Signe (RedwoodJS + BankID), PlayWellMinds (Flutter + Firebase + Rive), and the RISE Favorite Wardrobe app (Next.js + Firestore).

Products and services
- AI Proof of Concept (PoC inom AI) A service that helps clients explore and validate generative AI use cases through short proof-of-concept builds in roughly two weeks, producing tangible 'mini-applications' that reveal feasibility, limitations, and risks before a full production commitment. Targets organisations evaluating AI but unsure of fit, leveraging established LLMs such as ChatGPT, Claude, and DALL-E.
- App Development (Apputveckling) End-to-end development service covering native, web, and hybrid apps across iOS and Android. Prototyp's teams work with frameworks including React Native, Xamarin, and Flutter, advising clients on the right approach based on user needs and constraints. Targets organisations and start-ups needing cross-platform mobile delivery.
- Minimum Viable Product (MVP) Development Agile, iterative development service that builds products with the minimum features needed to validate user demand. Emphasises feedback loops, reduced time-to-market, and risk reduction; applies to both start-ups and large organisations.
- Flutter Development Specialised service building cross-platform iOS and Android applications using Google's Flutter framework. Single-codebase approach with native-near performance, flexible UI tools, and smooth animations. Used for clients like PlayWellMinds.
- Proof of Concept (General) Cost-efficient validation service for product or business ideas at an early stage. Creates drawings, models, maps, or other deliverables to test feasibility and ensure faster launch; suitable for both start-ups and established companies.
- Contentful Extensions Development Development service for extending the Contentful headless CMS through Contentful apps (formerly UI-extensions) for end users and custom scripts for developers. Prototyp positions itself as a leading player in extending Contentful functionality.
- User Interface Development (Gränssnittsutveckling) Holistic UI/UX development service creating user-friendly, accessible digital experiences. Builds complex algorithms and interactions for web services, Furhat robots, voice-controlled applications, and heart-rate-controlled games using wireframing, design sketches, and prototyping.
- Taco.ai Prototyp's own group-chat AI tool that lets an entire team interact with AI in a single shared chat window. Built on a single OpenAI API key so cost is split by usage rather than per-seat. Released publicly on Reddit and GitHub as open source.
- Norimaki Prototyp's RAG-based AI platform that lets organisations build internal AI agents or GPTs over their own document corpora. Responses are grounded in the organisation's data with citations back to source documents and pages, reducing hallucination and enabling privacy-sensitive use cases such as law-firm document Q&A.
