Vivian Midha Shen and the education of a beginner

The summer program was supposed to end. In 2017, Vivian Midha Shen had been teaching children computer science in an eight-week experiment that would become Juni Learning. Then the families wanted to continue. A trial had acquired an audience, and the audience expected her back in the autumn. Starting a company can sound like an act of solitary conviction. In this case, the children and their parents had a vote.

Shen remembers that request as a point of commitment. Flyers could be discarded. A summer project could finish when summer did. Continuing meant accepting responsibility for people who were already learning with her. The moment was small enough to fit into an ordinary family calendar: another class, another week. It made the enterprise considerably harder to put away.

Years later, her work would encompass live online instruction, AI-assisted college preparation and a seat in Y Combinator’s partnership. But the renewal remains a useful place to begin. Before the business could become an institution, somebody had to prefer a second term to a polite goodbye.

A political science student walks into a coding class

Shen grew up in the Bay Area and graduated from Gunn High School in Palo Alto. At Stanford, she initially considered political science. Friends from her freshman dorm were going to an introductory computer science lecture, so she went along. It is a pleasingly ordinary entrance into a technical career. Sometimes the future starts with wanting company on the way to class.

She graduated in 2014 with a computer science degree, concentrating in Human-Computer Interaction, and a minor in creative writing. The pairing offers two different ways of looking at a product: what can a person do with it, and how will that person understand it? A program may compile perfectly while its explanation leaves everyone else staring at the screen.

Her working life included software engineering at Google, consulting at McKinsey and product leadership at Operator, an AI commerce startup. At Operator she helped launch products in the United States and China. These were different jobs with different demands. Code, strategy and product decisions each supplied a view of how an organization gets something into another person’s hands.

The school experience she wanted to have

Shen’s interest in education had a personal foundation. She had wanted to explore subjects her school did not offer and remembered feeling unsure of herself while learning to code. Personalized instruction suited her better than the lecture format. Juni would give younger students access to the sort of attention she had found useful herself.

That distinction matters because a beginner’s difficulty can be surprisingly easy to misread. A student who hesitates may need a different explanation, a smaller next step or time to try. The visible performance is only part of the encounter. Building a business around individual instruction means making room for those differences within the lesson itself.

She co-founded Juni with Ruby Lee in 2017. Their connection went back to Stanford; both had been working on education ideas before they built together. Their earliest work included teaching children in Palo Alto. A university connection had become a working partnership, with actual students providing rather more useful feedback than a hypothetical customer ever could.

“the tools to figure out how to get unstuck”

Vivian Midha Shen, on what students need

The goal extended beyond learning commands. Shen wanted students to be prepared for the real world, including subjects and practical abilities that did not fit neatly into a standard school timetable. Her discussions of education ranged from computer science to public speaking. The child writing a program would eventually have to explain an idea to another human being.

A project a parent can understand

Juni’s early approach put projects at the center. Students could build something concrete, including a game, and accumulate work that showed their progress. A parent unfamiliar with programming could still understand the pleasure of seeing something their child had made. There is a fairly direct route from an incomprehensible string of code to a delighted explanation of how the game works.

Shen described working backward from the finished project to the skills a student would need. That made the destination tangible while leaving plenty to discover along the way. The design also gave instructors a purpose for the next technical concept. A piece of syntax becomes easier to care about when it helps make the thing on the screen behave.

Even the name carried the ambition in miniature. Juni combined junior and university. It was a compact way of giving children a place to study beyond the familiar boundaries of school, without requiring them to wait until they were old enough to arrive on a campus.

The machinery behind the lesson

Juni entered Y Combinator’s Winter 2018 batch. In 2020, it raised a $10.5 million Series A led by Forerunner Ventures, with investors including AME Cloud Ventures, Index Ventures and Pear VC. By then, the curriculum had expanded into math and English. The company reported delivering more than 50,000 classes over the three months preceding its funding announcement.

Those numbers describe a service with an increasingly demanding backstage. Fifty thousand classes mean many encounters that need to begin properly, with the right people and the right material. The finished lesson is the visible unit. The business must also support all the work required to make that unit repeatable.

As Juni grew, Shen had to redirect engineering attention toward internal tools and operations. The team had previously devoted substantial effort to student-facing products, including its code editor. Keeping the growing service dependable required attention to the systems behind those experiences. Retention and the capacity to support customers helped establish priorities.

It is an instructive detail in a founder’s career. A dashboard rarely gets the applause reserved for a product launch, but people depend on it. The engineering question becomes practical: which change will help the team deliver a better experience today, and continue doing so tomorrow? Sophisticated software can be useful. So can removing a recurring administrative headache.

A different way to reach the next student

Acely took personalized learning into college preparation. It launched out of beta in January 2024 as a spinout product from Juni, building AI-assisted study around the digital SAT and ACT. The setting was more specific than Juni’s broad menu of subjects. A student had a starting score, an intended result and a test date.

Those constraints create a clear planning problem. Time is limited, and practicing something already understood can consume time needed elsewhere. Acely’s approach uses performance information to tailor study plans and direct practice toward the areas a student needs to work on. The objective is a preparation routine that changes with the learner.

The company also described using human curriculum experts to check its questions and explanations. Automated personalization still needed educational material that could bear scrutiny. In June 2025, Acely received the EdTech Breakthrough award for Overall College Prep Company of the Year. Shen was then its founder and CEO.

“Every student has unique strengths and areas for improvement,” she said in the announcement. It is a plain sentence, and it identifies a difficult design requirement. A product serving many students has to make choices that remain useful to the individual sitting down to practice.

Acely subsequently announced Ron Schneidermann as its next leader. Building something also creates the possibility that another person will carry it forward. For Shen, the next public chapter would place her alongside people who were starting their own companies.

Back at YC, with a different job

On October 1, 2026, Y Combinator named Shen a General Partner, alongside Cron founder Raphael Schaad. Both had spent the previous two batches as Visiting Partners. Shen returned to the organization that had backed Juni, carrying experience of building education products through several different stages.

YC put the combined revenue of Juni and Acely at more than $50 million, with millions of users. It described Acely’s growth from zero to a $10 million run rate with a lean team. These are measures of the businesses she helped build. They also explain why a new founder might want her in the room when a product decision becomes an operating problem.

Her stated interests now reach into economic policy, job reskilling and supply chain resilience. The range is broad, but work and learning remain close neighbors. A person acquiring a skill and an organization trying to change how it operates both confront a version of the beginner’s problem: the next step is necessary before it feels familiar.

There is still a writing student in this technical career. Shen has spoken about studying creative writing at Oxford and discovering the difficulty of work without a simple correct answer. Her personal site opens with a modest declaration: “I’m tinkering here.” It suits a career that has repeatedly required her to become useful at something new.

The first Juni families asked for another term. Now other founders bring their own unfinished work. The audience has changed, and the problems have grown more complicated. There is still someone on the other side of the conversation trying to work out what to do next.
