Avihan Jain

I study mechanical engineering at Duke (’27).

I've built affordable soccer shoes, co-founded a copperware business, and started Bern, a language-learning toy company. I also build small software tools.

Outside work: soccer, guitar, travel, and bringing people together over food.

Things I've built

Bern

Founder & CEO
2024–2026

I wanted to help kids learn without another screen. We built a talking stuffed animal for language learning and tested it with 1,000+ beta testers. The biggest lesson came from parents: they wanted a clear purpose they could trust, which led us from open-ended conversation to language learning.

Sole Purpose

Founder · New Delhi
2021–2023

I saw talented soccer players who couldn't afford shoes. I designed and manufactured affordable soccer shoes, raising $5,000 and reaching 450+ players through 20+ NGOs and schools. I learned that an affordable product still needs to be something people want to wear.

Tambav

Co-founder · India
2020–2023

As lockdown shifted spending toward people's homes, we built a copperware and décor business selling across India, the UK, and the US. It grew to $300,000+ in revenue, with much of our selling happening through WhatsApp. My takeaway: timing and direct customer relationships mattered as much as the product.

Work with teams

Rely Health

GTM & Product Intern
June–August 2026

Rely needed a way to find customers beyond warm introductions. I built a conversational research tool that saved findings in HubSpot and surfaced 1,510+ high-fit leads. Conversations with account executives shaped the tool around how they actually researched and qualified companies.

Zamp

Founder's Office Intern
June–July 2025

I wanted to understand where team information was getting lost. After interviewing 10+ stakeholders, I designed an internal AI tool to bring context from Notion, Slack, and Linear together. Those interviews shaped the design.

Universal Toys

Manufacturing Intern
Summer 2022

I worked on product selection, pricing, factory audits, logistics, and warehouse operations at a toy manufacturer.

Fellow student founders

I've also helped teams at Jeani, Students Who Sit, and Swoop Tutors.

Smaller builds & experiments

A mix of personal tools, prototypes, and engineering projects.

Personal OS

Personal tool

I built a system to keep priorities, decisions, and open tasks in context I can read and correct. The key lesson: remembering something is only useful if the system can also recognize when it's wrong.

FindTime

iMessage prototype

A prototype for finding open time in your calendar and drafting a meeting message without leaving iMessage.

Tryb

Campus marketplace prototype

I wanted a smaller, curated way to resell clothes at Duke. I built a prototype for joining the community, submitting pieces, and browsing approved clothing drops.

FounderVoice

Writing prototype

A prototype that turns three spoken stories into LinkedIn drafts, with a chance to review and edit before using them.

BenchScout

Research prototype

Murky Outreach

Past collaboration · Prototype

I collaborated on tools for customer-discovery outreach: contact research, drafts, and follow-ups. Built and tested offline.

Battery monitoring

IIT Delhi research internship
Summer 2024

At IIT Delhi, I worked on detecting battery overheating in hot climates. I designed temperature-sensing hardware and a real-time calibration loop, then tested it across battery charge states.

Delivery drone

Real World Design Challenge
2021–2022

I co-led our team's delivery-drone proposal, focusing on the business plan, warehouse operations, and logistics. Our C-25 “Sigma” design placed first nationally and internationally in the Real World Design Challenge.

Community & giving back

Fifteen

Food, friends, conversation

MacCoy and I bring 10–15 people from different fields together over food. Phones away, with a mix of familiar faces and new people.

Founder dinners

Duke & beyond

I host dinners connecting founders and investors across AI, biotech, manufacturing, and other fields. The community has grown to 70+ founders and 10+ investors.

FIRST Robotics · Team Athena

Team 8868 · India · 2022

I led Team Athena's eight-person team at the Midwest Regionals in Chicago, where we won the Rookie All Star Award. I worked on robot construction and fundraising, alongside STEM outreach with underserved students and NGOs.

Outside work

I play recreational and intramural soccer, play guitar, and enjoy traveling. I grew up in a joint family, and spending time with people is still a big part of my life.
