From Idea to Launch in 4 Hours: Oneday Open Day🗽
🗽 Oneday Open Day: New York Saturday 3 October · 10am–3pm · Blender Space, 135 Madison Avenue, 8th floor
Oneday is an accredited MBA for entrepreneurs. Shark Tank meets university.
You don't write essays about business here. You build one. You're matched one-to-one with a mentor who has already done it in your sector — there are +200 of them, from operators who've raised hundreds of millions to founders who bootstrapped and sold. You join a squad of eight people building in the same space as you, and they're your people for the next eighteen months. You do it around your job, not instead of it. Guest lectures come from the founders of Vimeo, StockX and Blue Apron. At the end you have a business and a fully accredited MBA.
On 3 October, for the first time, we're opening one of our sessions to people who aren't in the programme.
It's graduation weekend in New York. Our class of 2026 will have just finished. Their mentors are in the city. So we're taking a session out of the programme, putting it on the 8th floor of Blender Space on Madison Avenue, and letting 100 people who've never been inside Oneday spend a Saturday in it.
⚡ Four hours of the real thing
Ideation — 2 hours. Your ideas go through the six tests we use on every idea inside the programme: is the problem real, do you have a right to play, can you reach the people who have it, can you build it, can you charge properly for it. Our AI agent then scores them on founder fit, depth of pain and how reachable your audience is, and tells you which one to back.
Build — 1 hour. You build a landing page for the idea you picked.
Risk — 1 hour. We map your assumptions on the risk matrix — what's uncertain and what actually matters — then run the testability check: for every risk that could kill you, the cheapest way to find out if it's true before you spend a penny.
✅ What you leave with
A chosen idea and the reason it beat the others. A landing page. A ranked list of what could kill it, with a test for each one you can run next week.
And a free 30-minute session with a Oneday mentor on the idea you worked on.
🍕 Then the last hour
Food, drinks and an hour with the people who've actually done it — mentors, and the founders who graduated the day before. Catering provided. Stay as long as you want.
📊 If you're wondering whether it works
75% of our founders graduate with a revenue-generating business. Our launch-lean method gets members to revenue in three months rather than nine. The most recent 135 graduates have generated $25m between them.
The MBA is accredited in the US through William Jewell College, recognised by the HLC, and eligible for Federal Financial Aid. Every year we back our strongest graduates with up to $50,000 on founder-friendly SAFE terms.
👥 Who's in the room
Frank Schneider runs the session. He built Speakeasy AI to $8M ARR and sold it to Verint in 2022. Oneday Mentor
Ranbir Arora, CEO and Co-Founder of Oneday.
Juan Linares, Head of Community and Senior Entrepreneur in Residence at Oneday.
Philip Mudhir, MBA Alumni and Oneday Mentor
Oneday mentors — the people who work one-to-one with our founders — and the founders themselves, including the class that just graduated. There's a corner of the room set aside for exactly that. Ask them anything. We won't be in the conversation.
🎯 Who it's for
People with an idea they haven't tested, or several they can't choose between. If you're already scaling something, this isn't the right session.
We should be straight with you
This is an open day. We're running it because some of you will want to join afterwards, and the honest way to decide is to sit in a session rather than read about one.
No pitch from the stage. Come, do the work, decide for yourself.
