About Mark Rober

Mark Rober is a mechanical engineer and content creator with 77 million YouTube subscribers and over 16.8 billion total views across 255 published videos. His background includes nine years at NASA's Jet Propulsion Laboratory, where he spent seven years contributing to the Curiosity Rover project—work he has documented in detail for his audience. He holds a Bachelor's degree in Mechanical Engineering from Brigham Young University and a Master's degree from the University of Southern California.

Rober's content spans engineering education, DIY projects, and science communication. He is the founder of CrunchLabs, a subscription service that delivers monthly buildable toys designed to teach engineering principles and problem-solving methodology. His video catalog reflects a consistent focus on making complex engineering concepts accessible to a general audience, drawing on his professional experience in robotics and mechanical design. The channel's scale and engagement metrics position it among the largest educational technology channels on YouTube, with an audience composition that skews toward viewers interested in STEM education and hands-on learning.

Mark Rober's estimated sponsorship rates

Mark Rober's estimated sponsorship rate for an integrated YouTube video placement ranges from $138,600 to $346,500, with a typical rate of $231,000. This pricing reflects his position in the high audience tier, driven primarily by his 77 million subscriber base—the largest among tracked tech creators in this database.

Several factors support this rate structure. Subscriber count is the dominant lever: Rober's audience is approximately 1.5 times larger than MR. INDIAN HACKER (51.1 million subs), the second-largest peer in the tech category, and nearly 3.7 times larger than Marques Brownlee (20.9 million subs). The tech niche itself commands competitive CPM rates, particularly for educational and engineering-focused content, which attracts audiences with higher purchasing power in categories like software, hardware, and educational platforms.

Format and platform also influence the estimate. YouTube integrated sponsorships—where a brand message is woven into video narrative rather than appended as a pre-roll or card—typically command premiums over other ad formats. Geographic concentration in the United States, where Rober is based, further supports higher rates due to advertiser demand and audience monetization standards in that market. The estimate is algorithmic and does not account for negotiated discounts, long-term partnership structures, or performance-based adjustments that may apply in individual deals.

Who should partner with Mark Rober?

Mark Rober's audience of 77 million subscribers represents one of the largest concentrations of STEM-interested viewers on YouTube. The channel attracts viewers across multiple demographic segments: primary audiences include school-age children and teenagers interested in engineering and science, adult hobbyists engaged in DIY projects, and educators seeking supplementary content for classroom use.

Brand affinity data indicates strong receptivity to companies in several categories: educational technology platforms, engineering and robotics kits, consumer electronics, hardware tools, science education subscriptions, and maker-space equipment. The CrunchLabs subscription model—a monthly engineering toy delivery service—demonstrates direct evidence of audience willingness to purchase tangible products tied to engineering education. This suggests sponsorship opportunities align well with fintech education, online learning platforms, STEM-focused consumer brands, and subscription services targeting intellectually curious audiences.

Compared to peers like Marques Brownlee (20.9 million subs), whose audience skews toward consumer electronics reviews and tech product launches, Rober's audience is more education-centric and project-oriented. The channel's 16.8 billion total views across 255 videos indicate sustained, long-term audience engagement rather than viral spikes, suggesting a loyal, repeat-viewing demographic. Audience geography is predominantly English-speaking, with significant concentration in North America and other developed markets where educational product spending is highest.

Mark Rober's growth and performance

We have only a single snapshot of subscriber data, collected on May 11, 2026, showing 77 million subscribers with no change recorded over the one-day span available in our tracking window. This limited data point does not permit analysis of growth trajectory, seasonal patterns, or acceleration trends. Average view counts for the last 30 days are also not yet available in our database. To assess Mark Rober's recent momentum and audience growth rate, longer historical tracking or additional data snapshots would be required.

How our pricing estimate works for Mark Rober

The sponsorship rate estimate is calculated algorithmically using subscriber count as the primary input, adjusted by niche-specific CPM multipliers, platform and format factors, and geographic weighting. The formula accounts for the relative earning power of tech-category audiences and YouTube's integrated video sponsorship format. This creator's estimate is based on metric estimation rather than direct community data; we have not yet collected pricing information from brand partnerships or sponsorship disclosures associated with this channel.

For a detailed explanation of how subscriber counts, CPM assumptions, and platform multipliers combine to produce the low, typical, and high rate range, see our methodology page. Actual sponsorship rates may vary based on contract length, exclusivity terms, performance guarantees, and negotiated adjustments that fall outside the algorithmic model.
