GradeWiz：康奈尔创始人从AI批改转向牙科AI销售
康奈尔创始人打造AI批改，节省60%时间，进入YC W25，随后转向牙科AI电话销售。
GradeWiz · 10x
做的是什么生意
GradeWiz used AI and computer vision to grade assignments and exams and provide question-by-question feedback; in 2026 the company sold an 'AI sales team' under the name 10x—connecting to clinic patient databases, finding overdue follow-ups and unscheduled treatment plans, and using AI phone calls and text messages to bring patients back to the clinic.
起因
Bohun (class of 2025 (25)) and Garg (class of 2025 (25)) hated grading while serving as TAs at Cornell and also saw professors overwhelmed by teaching and research; after LLMs became popular, they decided to use AI to solve grading. Product development took more than 2 years; in 2024 they entered the Cornell eLab student accelerator (eLab called it one of the most competitive that year), invested full-time over the summer with campus subsidies, and received guidance on legal matters and product iteration.
经过
In February 2025 they were selected for YC W25 (Cornell Chronicle reported an acceptance rate below 2%). At that time they had graded 30,000+ assignments, reduced grading time by 60%, gave detailed feedback for each assignment the next day, and piloted at Cornell, Cal Poly, Hunter College, Penn State, and Syracuse; in March, at Demo Day, TechCrunch listed them among '10 to watch,' positioning the product as doing the grading work that TAs 'hated'.
结果
Still running, but the product changed: in 2026 the main title on the YC company page became 10x (W25, 2 people, San Francisco (旧金山), Active)—an AI sales team helping dental clinics retrieve overdue patients: connecting to patient databases, identifying overdue follow-ups/lost patients/unscheduled treatment plans, and using AI phone calls and text messages to bring patients back to the clinic; example data said one Miami (迈阿密) clinic added more than US$30,000 in monthly revenue and one Los Angeles (洛杉矶) clinic retrieved 94 lost patients in one month, and it had served the 2 largest private dental groups in Chicago (芝加哥) and dozens of clinics covering all US time zones.
背景
2026年，这家YC W25公司更名为10x：一个AI销售团队，连接牙科诊所的患者数据库，找出逾期随访、流失患者和未排程的治疗计划，用AI电话和短信将人们召回诊所。其前身GradeWiz使用AI和计算机视觉批改大学作业——同样的创始人，同样的“AI自动化重复劳动”的赌注。
Max Bohun和Aman Garg是康奈尔大学的本科生和助教：批改堆积如山，教授超负荷，学生焦急地等待反馈。LLM普及后，两人决定用AI解决批改问题。产品开发花了两年多；2024年进入康奈尔eLab学生加速器，并在补贴下夏天全职投入。
2025年2月，GradeWiz入选YC W25（录取率低于2%）：当时已批改3万多份作业，批改时间减少60%，每份作业次日给出详细反馈，并在康奈尔、Cal Poly、Hunter、Penn State和Syracuse试点；3月Demo Day上，TechCrunch将其列为“值得关注的10家”之一。
教育市场的付款速度显然跟不上：2026年YC公司页面主标题变为10x，GradeWiz被降级为“Previous Launches”。10x的示例数据是迈阿密一家诊所月收入增加超3万美元，洛杉矶一家诊所一个月召回94名流失患者，客户包括芝加哥最大的两家私营牙科集团——同样的AI跟进引擎，换成了更紧迫的买家。
这件事要成立，得有什么
- 创始人是助教；批改慢，所以他们给自己建了个解决工具。
- eLab提供补贴和建议，使他们能全职投入，并进入YC W25。
- 转型保留了同一套AI引擎；牙科诊所付费意愿更强。
- 他们把公司页面改成10x，放弃GradeWiz以迎合市场信号。
可借鉴之处
自动化重复劳动可以跨市场转移；教育业付款慢，牙科诊所付款快，所以转向。
后续进展
截至2026-09-01：公司以10x运营；YC页面显示团队2人，位于旧金山，状态活跃；官方示例称迈阿密一家诊所月收入增加超3万美元，洛杉矶一家诊所一个月召回94名流失患者；客户包括芝加哥最大的两家私营牙科集团、萨克拉门托最大的一家，以及覆盖美国所有时区的数十家诊所；GradeWiz批改业务没有公开后续。
