What Notjust.dev does
Notjust.dev is a Barcelona-based, founder-operated education and developer-tools company built around React Native and Expo mobile app development. Founded by Vadim Savin — a developer with a FAANG background, 100+ apps shipped, and two prior startup co-founding roles — the company serves mobile developers and indie mobile founders through four interlocking product lines: the React Native Mastery flagship course (7 real-world app projects, lifetime access, hosted on Kajabi at academy.notjust.dev), the notJust Incubator (a 10-week cohort-based launch program capped at 10 founders per cycle, with founders retaining 100% equity), production-ready Expo templates (ChatAI for AI chat, ImageAI for AI image generation, Ecommerce for mobile commerce), and community/sponsorship assets including notJust.Club, the notJust.Podcast, a Discord community, and a 33,943+ subscriber newsletter.
The technical foundation is Expo SDK 55 + React Native + TypeScript on the front end, with Supabase (Postgres, Auth, Edge Functions, pgVector) as the backend, RevenueCat for in-app subscriptions, Sentry for crash reporting, PostHog for product analytics, and integrations to OpenAI (GPT-4o, GPT-4o mini, GPT-4.1, o3-mini), Anthropic, Gemini, ElevenLabs (voice), and LangGraph (autonomous code-executing agent). Templates ship with auto-versioned EAS Build/Submit workflows that publish to the App Store and Play Store on every push to main. The business model mixes one-time licenses (course and templates at €99–€199), professional-services pricing for the Incubator (undisclosed), and recurring PRO Community subscriptions, monetized through a product-led and community-led GTM that relies on owned YouTube (135k+ subs), the newsletter, and direct sponsorships from Expo, RevenueCat, AWS, Hostinger, Voximplant, Stream, Taskade, and Sentry. The company is bootstrapped, founder-owned, and operates with 1–10 employees from C/ Balmes 129bis in Barcelona.

Notjust.dev partnerships and signals
Strategic signalPartnerships
Five partnerships are on record, tiered core and minor.
- ExpocoreExpo and notJust.dev have a deep strategic relationship. When many developers were skeptical of Expo, notJust.dev created practical, real-world tutorials that showcased Expo's power and flexibility, helping it become a widely adopted tool. Charlie Cheever (Co-founder & CEO of Expo) has provided a testimonial. This is a mutual relationship where notJust.dev's content elevated Expo's adoption, while Expo's platform is the foundation of notJust.dev's tutorials and templates.
- RevenueCatcoreRevenueCat is integrated into notJust.dev's templates (ChatAI) and tutorials (Headspace Clone project). RevenueCat powers in-app subscription management, cross-platform purchase handling, and receipt validation. The partnership provides notJust.dev with a production-grade monetization solution and positions RevenueCat in front of 135k mobile developers.
- HostingerminorHostinger is listed as a partner/sponsor on notJust.dev, reaching mobile developers through the platform's content and tutorial ecosystem.
- TaskademinorTaskade (AI productivity/notes tool) is listed as a partner on notJust.dev, receiving visibility in front of the platform's developer audience.
- SupabasecoreSupabase (Postgres, Auth, Edge Functions, and pgVector) is the primary backend used across all notJust.dev templates and many tutorials. It enables database, authentication, AI vector embeddings, and edge function streaming. The relationship positions Supabase as the go-to backend for React Native apps built by the notJust.dev community.

Notjust.dev competitors and assessment
Company assessmentDirect peers
- Egghead.io: Bite-sized expert-led video courses for web developers (subscription model). Comparable audience (professional developers upskilling) and creator-instructor supply model; broader scope than React Native but overlaps on dev upskilling.
- buildspace: Cohort-based nights-and-weekends program helping indie founders build and ship software/web3 products. Closely comparable to notJust Incubator on cohort size, accountability model, equity retention, and target indie-founder segment, though focused on web3 earlier-stage builders.
- Scrimba: Interactive coding course platform with a creator-instructor model and subscription access. Comparable on the 'paid creator-led coding education' axis, though it leans more interactive-in-browser than React Native-specific.
- Academind (Maximilian Schwarzmüller): Maximilian Schwarzmüller's creator-led platform (YouTube, Udemy, dedicated courses) covering React, React Native, Node, and full-stack development. Directly comparable creator-led dev-education model, audience overlap with self-taught mobile developers, and similar GTM.
- Code with Mosh: Creator-led (Mosh Hamedani) programming course platform selling perpetual-license video courses on web, mobile, and backend development. Closely comparable model: solo founder, one-time paid courses, free YouTube channel as funnel, no sales team — and Mosh's scale benchmarks the category's ceiling.
- App Brewery (Angela Yu): Creator-led mobile-development bootcamp courses (iOS, Flutter, full-stack) sold as one-time purchases via Teachable/Udemy, with Angela Yu as the public face. Compares directly to notJust.dev on model (creator-led perpetual courses), target buyer (aspiring mobile developers), and product shape (project-based curriculum).
- React Native School: Dedicated React Native and Expo training site offering video courses and a community. Most direct category overlap, also selling paid React Native education to developer-learners; smaller creator-led footprint but same niche.
Broad incumbents
- Microverse: Cohort-based, peer-to-peer remote software engineering bootcamp with a similar 'structured accountability' pedagogy to the Incubator. Comparable on the paid, cohort-driven developer upskilling concept though serving a different end-customer (career switchers vs indie founders).
- Frontend Masters: Subscription-based expert-led courses for frontend and full-stack engineers (React, JavaScript, etc.). A larger and more established player in the same paid dev-education category with overlapping developer audience and similar course-product model.
Emerging players
- Catalin Miron (Catalin's Courses): Independent creator producing in-depth React, React Native, and Expo tutorials on YouTube and via paid courses. Closely comparable solo-creator model and content niche; smaller footprint than notJust.dev but operating in the same audience.
