Mark Rober, a 46-year-old American YouTuber, mechanical engineer, and inventor, has built a massive platform around making science engaging. Drawing on his background as a former NASA engineer, web video producer, and television producer, Rober launched CrunchLabs to teach engineering and scientific thinking to the next generation. The subscription-based STEM toy and robotics company combines physical building kits with digital media, allowing kids and adults to learn directly from Rober's design philosophy.
The product lineup is structured around three distinct subscription lines tailored to specific age ranges. For the youngest builders, the Creative Kit was launched in 2025, targeting children aged 6 to 10. The company's flagship offering, the Build Box, was introduced earlier in 2022 for kids aged 8 to 13. The Build Box subscription features flexible pricing tiers, costing $27.45 per box under the annual plan, $29.95 per box under the monthly plan, and $32.95 per box under the quarterly plan.
For older audiences aged 14 and up, CrunchLabs introduced the Hack Pack in April 2024. This advanced line shifts the focus toward robotics and coding. Each Hack Pack box delivers a more complex challenge, containing an Arduino microcontroller and a power bank when required. Unlike the monthly options, the Hack Pack is delivered bi-monthly (six boxes per year). It is priced at $399.95 for an annual prepaid subscription, $72.95 per box when billed every two months, or $79.95 per box on a semiannual schedule.
Every single box delivered by CrunchLabs comes packed with all the necessary building materials, a detailed picture-based instruction booklet, and clear explanations of the featured STEM concepts. To celebrate their progress, builders also receive a special gear badge and gain access to exclusive instructional videos hosted by Mark Rober. The subscriptions also feature high-stakes sweepstakes opportunities. Creative Kit and Build Box subscribers are automatically entered for a chance to win a "Platinum Ticket" sweepstakes (valued at $4,500), which includes a trip to visit the CrunchLabs headquarters and create a project with Rober. For older builders, the Hack Pack subscription includes a chance to win the "Platinum Diploma" sweepstakes, offering a massive $80,000 prize towards college tuition alongside a trip to the facility. The promotional period for the Hack Pack sweepstakes ends on April 30, 2027, while the Build Box sweepstakes runs until May 31, 2027.
