The most valuable resource in a university department isn't grant money or lab space. It's a professor's Sunday afternoon. Max Bohun and Aman Garg, both Cornell undergraduates, spent two years watching their instructors lose those afternoons to a mountain of handwritten problem sets and essays. Their startup, GradeWiz, is a simple proposition: let a computer do the first pass [Cornell Chronicle, February 2025].
It’s an AI grading assistant that uses computer vision to parse scribbled calculus proofs, physics diagrams, and biology sketches, alongside more standard PDFs and essays. The founders claim it cuts grading time by 60-80% and returns detailed feedback to students by the next day [GradeWiz site]. The wedge is straightforward. No district-wide procurement, no seven-figure sales cycle. Just a professor, drowning in papers, willing to try something that promises a weekend back.
The pilot wedge
GradeWiz’s early traction is a classic campus story. The founders, participants in Cornell’s eLab accelerator in 2024, started by solving a problem they saw every day. They piloted the tool with educators at their own university and a handful of others, including Pennsylvania State University and California Polytechnic State University [Cornell Chronicle, February 2025]. The reported metrics from these pilots form the core of their pitch: over 30,000 submissions graded, with 97% accuracy and less than 3% requiring manual intervention [Cornell Daily Sun, September 2025]. For a pre-seed company, that’s a compelling amount of real-world validation. It’s also the kind of data that got them into Y Combinator’s Winter 2025 batch and a $500,000 pre-seed round [Crunchbase, March 2025].
The technical bet is on breadth. Most automated grading tools focus on a single domain,multiple-choice quizzes or coding assignments. GradeWiz is aiming for the messy middle of a liberal arts and STEM education, where a single course might involve essays, graphs, and equations. Their stated coverage includes math, physics, chemistry, earth science, biology, and essays [GradeWiz site]. That’s a broad surface area to defend, but it’s also the exact pain point for a harried professor teaching a core curriculum class.
The unit economics of a saved hour
The business model, for now, appears to be a straightforward SaaS play aimed at individual educators or departments. The real unit economics here aren’t in the monthly subscription fee, which remains undisclosed. They’re in the hours saved. A back-of-the-envelope calculation: if a professor teaching 80 students saves 5 minutes per assignment, that’s nearly 7 hours reclaimed per grading cycle. Over a semester, that time adds up to a small research project, or a few extra office hours, or simply a less burned-out instructor. For a department chair, that’s a retention tool. GradeWiz isn’t just selling software; it’s selling capacity back into a system running at a deficit.
The scaling cliff
Of course, moving from a dozen friendly university pilots to a scalable, defensible business is a different kind of problem set. The risks are well-defined.
- The founder gap. Bohun and Garg are sharp undergraduates with deep context on the user problem, but they have no public record of scaling a B2B SaaS company, building a sales team, or navigating procurement at the university level. Y Combinator provides a playbook, but execution is local.
- The accuracy asymptote. A 97% accuracy rate in controlled pilots is impressive. Maintaining that rate across hundreds of institutions, thousands of idiosyncratic grading rubrics, and the infinite variety of student handwriting is the hard part. The 3% manual intervention could become a scaling bottleneck.
- The competitor vacuum. The verified facts show no named direct competitors, which is either a massive greenfield opportunity or a sign that the market is historically difficult to crack. Large learning management systems like Canvas or Blackboard could decide to build this feature in-house, and incumbent edtech giants like Turnitin have the existing customer relationships to move quickly.
The company’s immediate goal is to convert its pilot footprint into paying contracts and expand beyond the initial eight colleges [Y Combinator on X, 2025]. The next twelve months will test whether a product born in a Cornell dorm can build the sales and support infrastructure required to become a real company. To win, GradeWiz must ultimately beat not a flashy AI startup, but the default: the overworked professor who, however reluctantly, trusts their own red pen more than any algorithm.
