## Brilliant

Brilliant takes a different approach to learning: rather than watching long videos or reading dense textbooks, you build understanding by solving interactive problems. Lessons break big ideas down into small visual steps, so concepts in algebra, calculus, statistics, logic and Python become intuitive. The platform is designed for self-paced learners from roughly middle-school level up to college and beyond, and it adds a new AI tutor called Koji who asks guiding questions and sketches on screen to help you find answers yourself.

Beyond pure math, Brilliant covers computer science fundamentals, programming, data analysis and how modern AI actually works, including neural networks, tokenization and model reasoning. Each track uses mastery assessments that adapt to your level, revisiting weak spots and serving targeted practice so progress is measurable rather than vague. Real-world examples, such as image filters or password security, connect abstract ideas to everyday technology.

The platform is also used by schools and families. It is accredited by ACS WASC, certified under the kidSAFE/COPPA program, and offers classroom and teacher programs so educators can assign adaptive lessons and homework. For individual learners, the app is available on web and mobile, with progress syncing across devices.

**Pricing & Plans:** Brilliant uses a freemium model: a limited free experience is available, while a Premium subscription unlocks the full course library and unlimited practice. Annual plans are the cheapest per month, and there are separate school/classroom plans.

- **Interactive problem-based lessons:** Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
- **Koji AI tutor:** A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
- **Adaptive mastery assessments:** Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
- **Coding and CS foundations:** Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
- **Courses for schools and families:** Accredited classroom programs let teachers assign adaptive lessons, with kidSAFE/COPPA-certified privacy protections.

**Strengths:** Hands-on, visual format makes abstract concepts easier to grasp; Access to the Koji AI tutor that guides rather than gives away answers; Accredited and kidSAFE/COPPA certified, suitable for schools and families; Works across web and mobile with syncing progress

**Limitations:** Full course library requires a paid Premium subscription; Not a replacement for formal instruction or credentials; Some advanced or niche topics are not covered deeply

## StackRef

StackRef is an independent consulting practice run by Keith McDuffee, a CISSP-certified cloud architect with more than 20 years across infrastructure, DevOps, and security, currently also a Senior Director of DevOps and Application Security. The consulting side provides hands-on help designing, securing, and optimizing cloud environments on AWS, GCP, and Azure, with an emphasis on being precise and clear about requirements rather than over-charging or over-complicating.

Alongside consulting, StackRef offers its own designed, self-hosted, end-to-end internal hackathon manager. This product supports the hackathon lifecycle with features such as sandbox environments, AI-assisted scoring, and team collaboration, making it useful for organizations that want to run internal innovation events on their own infrastructure rather than a third-party SaaS.

Client reviews highlight fast response, deep end-to-end infrastructure knowledge, and a willingness to dig into problems and propose multiple solutions. Being based near Boston and working remotely with clients worldwide, StackRef fits teams that want a senior, accountable expert plus a purpose-built internal hackathon tool. Pricing is arranged through a free intro call or direct email.

**Pricing & Plans:** StackRef does not publish fixed prices. Its model is contact for pricing: you book a free 30-minute intro call or email directly to discuss consulting scope or the self-hosted hackathon platform and receive a quote.

- **Cloud architecture consulting:** Hands-on architecture, security, and cost optimization across AWS, GCP, and Azure, led by a CISSP-certified architect with 20+ years of experience.
- **Security and compliance:** Focused engagements on hardening cloud environments and supporting compliance, with an emphasis on robust, well-governed infrastructure.
- **Cost optimization:** Practical work to reduce cloud spend and right-size infrastructure without sacrificing reliability.
- **Internal hackathon platform:** A self-designed, self-hosted, end-to-end internal hackathon manager covering sandbox environments and AI scoring to run innovation events.
- **Direct expert access:** Booking a free 30-minute call and working directly with the principal architect instead of going through a queue.

**Strengths:** Direct access to a CISSP-certified architect with 20+ years of experience; Cross-cloud expertise spanning AWS, GCP, and Azure; Consulting paired with a self-hosted hackathon platform; Free 30-minute intro call before committing

**Limitations:** Consulting capacity is tied to one principal architect, which can limit parallel engagements; Hackathon software and consulting are distinct offerings that may suit different buyers; No published fixed pricing, so budgeting requires a conversation; The platform is niche, focused on cloud architecture and internal hackathons rather than broad team tooling
