About Math Says Yes and Opalstack

In their own words, as submitted to SaaSHub.

Math Says Yes
Opalstack

Statistics keeps being right when instinct says no. Put 23 people in a room and the odds that two share a birthday are about 50%. Math Says Yes collects facts like that and walks through the reasoning until each one makes sense. The format is a scrollable feed of cards. Most cards ask a quick...

  • Developer-Friendly Hosting
    Opalstack is designed with developers in mind, offering SSH access, Git integration, and support for multiple programming languages and frameworks including Python, Node.js, Ruby, and PHP, giving developers granular control over their hosting environment.
  • Affordable Pricing
    Opalstack offers competitive pricing for shared and managed hosting plans, making it an accessible option for small businesses, freelancers, and individual developers who need robust features without enterprise-level costs.
  • Modern Control Panel
    Opalstack provides a clean, modern, and intuitive web-based dashboard for managing sites, applications, databases, and email accounts, which is a significant improvement over older-style hosting control panels like cPanel.
  • Strong Support for Multiple Applications
    The platform supports a wide variety of application types including WordPress, Django, Flask, Express, static sites, and more, allowing users to host diverse projects on a single account with easy deployment.
  • Reliable Infrastructure and Support
    Opalstack is built by former WebFaction team members, bringing experienced hosting expertise. They offer responsive customer support and a reputation for stable, well-managed server infrastructure with good uptime.

Possible disadvantages

  • Smaller Community and Ecosystem
    Compared to major hosting providers like DigitalOcean, AWS, or even shared hosts like SiteGround, Opalstack has a smaller user base, which means fewer community tutorials, third-party guides, and forum discussions available for troubleshooting.
  • Limited Scalability Options
    Opalstack is primarily a shared hosting provider, which means it may not be the best choice for high-traffic applications or projects that require rapid, on-demand scaling of resources like CPU, RAM, or storage.
  • Not Ideal for Beginners
    While developer-friendly, Opalstack's approach can be intimidating for non-technical users. Setting up applications often requires familiarity with the command line and server configuration, which may not suit those looking for simple one-click solutions.
  • Limited Data Center Locations
    Opalstack offers a relatively small number of data center locations compared to major cloud providers, which may result in higher latency for users targeting audiences in regions not well-served by the available server locations.
  • Fewer Managed Services and Add-ons
    Unlike larger hosting platforms, Opalstack lacks a wide range of managed add-on services such as built-in CDN integration, managed backups with granular restore options, or one-click SSL management that more mainstream providers offer out of the box.

Questions & Answers

As answered by people managing Math Says Yes and Opalstack.

Why should a person choose your product over its competitors?

Math Says Yes's answer

Most learning platforms ask for a commitment: create an account, pick a track, work through lessons. Math Says Yes is built for a two-minute gap — open it, meet one surprising fact about probability or risk, understand why it's true, close it. Nothing is behind a paywall or a signup wall, every fact is sourced rather than asserted, and the interactive demos let you test a claim yourself instead of taking our word for it. It isn't a curriculum like Brilliant or Khan Academy; it's the thing that makes people curious enough to go looking for one. The daily five-question challenge gives you a reason to come back without a syllabus.

What makes your product unique?

Math Says Yes's answer

Math Says Yes turns counterintuitive statistics into something you scroll. Nearly every card asks you to guess before it reveals the answer, so you commit to a hunch first and then find out why your instinct was off — that moment of being wrong is what makes the fact stick. Explanations are short and in plain language, every claim cites its source, and many cards include an interactive chart or slider so you can change the numbers and watch the result move. Reading is free and needs no account; signing in only adds progress sync and streaks.

How would you describe the primary audience of your product?

Math Says Yes's answer

Three overlapping groups. Curious adults who enjoy numbers but don't want a course — the popular-science reading crowd who like having an intuition overturned. Students in secondary school and early university taking statistics or probability who want the ideas to click before an exam. And teachers, who use a card as a lesson starter: put the fact on the board, let the class vote, then walk through the demo together. The data-literacy cards on misleading charts and survivorship bias also fit media-literacy lessons.
