Leave, sabbatical or dual role: options for leaving academia
Core idea#
You rarely have to choose between "stay in academia" and "quit to found". Most universities and institutes offer a range of in-between options, and choosing well can cut your personal risk sharply without hurting the company. The catch is that each option has rules about time, roles, use of the lab and conflicts of interest, and investors care about which one you choose.
There are four basic options:
- Stay in post, advise or consult. You keep your job and give the company a limited amount of time, usually capped by your institution's outside-work rules. You can't normally run the company day to day.
- Dual role. You keep your post but take a defined executive or part-time role in the company, with your institution's permission and a conflict-of-interest management plan.
- Sabbatical or leave (paid or unpaid). You step away from academic duties for a semester to two or more years to work full time in the company, with a right to return.
- Resign. You leave the institution and commit fully.
The right choice depends on your role in the company, the stage of the company, what investors will require, and how reversible you need the decision to be.
Who it's for: faculty, research staff and postdocs on contracts who are founding a company based on their research, and PhD students thinking about the timing of submission and starting.

What investors actually look for#
At pre-seed, investors typically want at least one founder full time and want the others' time commitments written down. They will ask:
- Who is full time, and from when?
- If someone is on leave, what happens when the leave ends? Will they return to the university or resign?
- Does the institution's policy allow the person to hold equity and a role? Is there a written approval?
- Is any lab work for the company happening on campus, and under what agreement (playbook 2.14)?
A common pattern at seed: the PI stays in post as scientific founder and adviser; a postdoc or student goes full time as CEO or CTO; the PI's role and time are written into the shareholders' agreement. A leave of absence for the full-time founder, timed to cover the first 12 to 24 months, keeps a way back if the company fails early.
What the rules say: India, the US and the UK#
Rules vary by institution and change. Always read your own institution's current policy, and get approvals in writing.
India#
- National framework. The Ministry of Education's National Innovation and Startup Policy (NISP, 2019) asks institutions to let faculty and staff take a semester or a year off, as sabbatical, unpaid or other leave, to work on a startup and then return (NISP presentation, MoE Innovation Cell). It also says faculty holding an executive or managerial role in a startup for more than three months should go on sabbatical, leave without pay or use existing leave (IISER Kolkata, summarising NISP section 7). It asks faculty to keep institute research clearly separate from company work, and not to use project staff on company work (NISP presentation).
- IIT Delhi. Faculty mentoring a startup may only hold non-executive roles, unless on sabbatical or lien. More than one day a week on such work is allowed only when on leave. Faculty going full time must take sabbatical or leave in the first year (IIT Delhi). IIT Kanpur. Faculty can take a sabbatical and work full time in the company, or use their consultancy days for it (IIT Kanpur Faculty Entrepreneurship Policy).
- Other institutes (IIT Palakkad, IIT BHU, IIITs, IISERs) have similar policies, often allowing sabbaticals, relaxed hours and recognition of startup work in appraisals (IIT Palakkad).
- Equity. Many institute policies also take equity from faculty startups. Read the equity clauses together with the leave clauses (playbook 2.11).
United States#
- One day a week is the common cap. Many universities limit outside professional activity, including startup work, to about one day a week during the academic year. Examples include Yale (Yale Provost), Brown (Brown policy) and Purdue, which requires leave once startup work exceeds that (Purdue).
- No day-to-day management while employed. Some universities bar faculty from dayto-day management of a company except while on leave (Columbia).
- Summer months. Faculty on nine-month appointments may not be bound by the cap in unpaid summer months, though disclosure rules still apply (Brown).
- Federal funding. If your lab has federal grants, financial conflict-of-interest rules require disclosure of equity or consulting income from a related company, and often a management plan (Chapman University guidance).
United Kingdom#
- Universities set their own outside-work and consultancy rules, often as an annual allowance of days, and most have a spinout policy that covers staff roles, equity and leave.
- Secondments and part-time contracts are common ways to free founder time. Fellowships such as the Royal Academy of Engineering Enterprise Fellowship can fund a researcher's time while they build the company (playbook 1.10).
- The 2023 Independent Review of University Spin-out Companies recommended that universities make spinout terms and staff policies clearer and faster; check how your university has responded (playbook 2.11).
Step by step: getting the arrangement you need#
1. Decide your role first, then the time it needs#
Write down the role you'll play for the next 18 months (CEO, CTO, scientific founder, adviser) and the hours it actually takes. A CEO raising a seed round can't do it in one day a week. A scientific founder can.
- Read three documents
- Your institution's outside activity or consultancy policy (time caps, approvals). Its startup or entrepreneurship policy (roles, leave, equity).
- Its conflict-of-interest policy (disclosures, management plans, students in your lab).
Make a one-page summary: what's allowed, what needs approval, who approves, how long it takes.
- Talk to the right people, in the right order
- The tech transfer or innovation office , which usually knows how others have done it (playbook 2.03).
- Your head of department , who will need to cover teaching and supervision.
- The research office or conflicts committee , if you have grants or students involved.
4. Propose a specific plan#
Include: your role; time commitment; start and end dates; how teaching and students will be covered; how lab and company work will be kept separate; and what happens at the end of the leave. A specific proposal gets approved faster than an open question.
5. Manage the conflicts#
- Students and postdocs. Don't have students in your lab work for the company on their thesis time. If a student is also a founder or employee, set up a separate adviser or mentor for their academic work (playbook 2.13).
- Lab resources. Company work on campus should run under a written agreement: incubator space, a sponsored research agreement or a facilities-use agreement (playbook 2.14).
- Purchasing and grants. Don't direct university purchases to your company or write grants that benefit it without disclosure.
6. Get it in writing, and plan the end#
Keep the approval letter. Six months before a leave ends, decide: extend the leave, return part time (often as a scientific adviser), or resign. Tell investors and the board early.
Worked example#
Dr. Meera Rao, an associate professor at an Indian institute, co-founds a sensor company with her postdoc, Vikram. Vikram resigns his postdoc and becomes full-time CEO. Meera applies for one year's sabbatical under the institute's startup policy to be CTO through the seed round, with an option to extend for a second year. Her students' work stays on grant-funded projects; company work happens in the institute incubator under a facilities agreement. At month nine, the company raises a seed round; Meera decides to return to the institute as scientific founder and adviser, and the company hires a full-time VP Engineering. Her shares were set up with vesting tied to her role (playbook 3.06), so the change doesn't create a dispute.
Scripts#
Asking your head of department#
"I'm co-founding a company based on our [technology], working with the tech transfer office. I'd like to take [one year's sabbatical / unpaid leave] from [date] under the institute's startup policy. Here's my plan for covering my teaching and supervising my students, and how I'll keep the lab's work separate from the company's. Can we go through it together before I apply formally?"
When an investor asks about your commitment#
"I'm on approved leave until [date], working full time on the company. Before that date, the board and I will decide whether I extend, resign, or move to a scientific founder role while we hire. That decision depends on the seed round, and you'll be part of it."
Setting expectations with your co-founder#
"While I'm in post, I can give the company one day a week and evenings for advice, not day-to-day management. That's set by the university's rules. Let's write down what that means: which decisions I'm in, which you make, and how my vesting reflects it."
Common mistakes#
- Starting work before getting approval. Retrospective approvals are harder, and undisclosed conflicts can become disciplinary matters.
- Taking an executive title while still in post. Many policies forbid this without leave. Use "scientific founder" or "adviser" until approved.
- Using students or lab staff for company work. This is the most common source of serious disputes.
- Letting a leave end without a decision. Investors and co-founders need to know months ahead.
- Ignoring the vesting link. If your time commitment changes, your equity should reflect it. Agree this in advance (playbook 3.06).
- Resigning when leave was available. Leave keeps a safety net at little cost to the company.
