Giving back: angel investing and mentoring done well
A founder’s money and time can change another founder’s odds. Done with portfolio discipline, real diligence and honest advice it helps them; done for status it mostly helps the giver feel useful.

A founder who has built something is asked, sooner or later, to give back: a cheque for a younger founder, an hour of advice, a seat on an advisory board. The impulse is generous. The execution often is not. Cheques written in a rush, advice given without listening and introductions promised and forgotten help the giver feel useful more than they help the founder.
This lesson is about giving well. It covers the arithmetic that should shape any angel portfolio, how many cheques and over how long, the rules in India as they stand, the diligence and help that go with a cheque, and mentoring that leaves the founder stronger rather than dependent. The test throughout is simple: does this help the founder, or does it help my ego?
Give for the founder, not for the ego
Begin by being honest about motive. Some of the reasons experienced founders invest and mentor are good: to stay close to building, to repay the people who once helped them, to learn a new sector. Some are less good: to be seen as a power broker, to stay important after an exit, to tell the story of the first company again. The good reasons produce discipline. The less good ones produce too many cheques, too much advice and too little follow-through.
Brad Feld calls his approach to mentoring Give First. As Techstars summarises it, it is giving without defining the return in advance, and listening from the founder’s perspective rather than one’s own. That is a useful standard for both money and time.
The arithmetic of angel cheques
Early-stage returns follow a power law. Paul Graham put it plainly in Black Swan Farming: effectively all the returns are concentrated in a few big winners. He reported that two companies, Dropbox and Airbnb, accounted for about three quarters of the value of Y Combinator’s portfolio at the time, and that there is probably at most one company in each batch that will significantly affect returns. An angel investor faces the same distribution with a far smaller portfolio.
The consequence is that the number of cheques matters more than the skill of picking any one of them. If each company has a small chance of becoming the outlier, the chance of holding at least one rises with every cheque, and it rises slowly. The figure below shows the curve.
With the defaults, twenty cheques of ₹10 lakh at a 3 per cent chance each give a 46 per cent chance of holding at least one outlier, for ₹2 crore committed over four years. Five cheques give 14 per cent. Forty give 70 per cent. Move the odds slider and the shape stays the same: a handful of cheques is a lottery ticket, a few dozen begin to be a portfolio. That is why an angel who writes three large cheques to friends in the first month after an exit has not built a portfolio at all.
One cheque is a ticket. A portfolio is dozens of small cheques, written over years, from money you can lose entirely.
How much, how many and over how long
Three numbers set an angel portfolio. The total: an amount you can lose entirely without changing your family’s life, taken from the risk capital described in the [lesson on the year after the exit](/library/what-to-do-after-the-exit). The number of cheques: enough to give a fair chance of an outlier, which on most honest assumptions means a few dozen rather than a few. The pace: spread over several years, so that the portfolio is not all bought at one point in the cycle. Divide the total by the number and you have the cheque size. Keep some of the total back for follow-on cheques in the companies that are working.
A worked example. A founder sets aside ₹2 crore of risk capital for angel investing. They keep ₹60 lakh back for follow-on cheques in the companies that earn them, which leaves ₹1.4 crore for first cheques. At ₹5 lakh each that is twenty-eight companies. Written over four years, it is seven cheques a year, roughly one every seven weeks, which is also a pace at which twenty honest hours of diligence on each is possible alongside a life. If the same ₹2 crore went into four companies at ₹50 lakh each in the first month, the figure above says the chance of holding an outlier would be about one in nine on the default odds.
Most angels find the cheque size smaller than they expected. That is fine. A small cheque with real help attached is often more valuable to a founder than a large cheque from someone who disappears.
The rules in India, as they stand
Two changes have reshaped Indian angel investing. First, the tax on share premiums often called angel tax has gone: the Budget memorandum for 2024–25 said section 56(2)(viib) would not apply from assessment year 2025–26. Second, SEBI rewrote the framework for angel funds in 2025. As Vinod Kothari Consultants explain, only accredited investors may now invest through an angel fund, investment in a single startup must fall between ₹10 lakh and ₹25 crore including follow-ons, and angel funds registered before the change had until 8 September 2026 to stop taking new money from non-accredited investors. Investing directly in a company remains possible; investing through a SEBI-registered fund now requires accreditation. These rules were checked in October 2026; confirm them before you commit. The [lesson on Indian angel investors](/library/angel-investors-in-india-who-they-are) describes the networks and platforms.
Diligence before, and help after
The best-known data on angel returns is American and old, but it points in a clear direction. The Angel Investor Performance Project by Rob Wiltbank and Warren Boeker studied 538 angels in groups, 3,097 investments and 1,137 exits and closures. Exits returned 2.6 times the money on average over about three and a half years. The median angel spent 20 hours on diligence before investing; investments with high diligence returned 5.9 times against 1.1 times for low diligence. Angels who engaged with the company once or twice a month saw 3.7 times against 1.3 times for those who engaged once or twice a year. These are associations, not proof that diligence or involvement caused the returns, but they are a reason to do both.
Diligence for an angel is not a data room review. It is twenty honest hours: time with the founders, calls with three customers, a look at the numbers that matter for the business, a reference call on the founders as the [lesson on reference calls](/library/choosing-investors-run-reference-call-first) describes in reverse. Help after the cheque is specific: an introduction to a customer, a hire or an investor; a review of a pricing page; an hour before a hard board meeting. Offer it on a rhythm and keep every promise you make.
Mentoring done well
Mentoring is the same discipline with time instead of money. The founder makes the decision; the mentor helps them make it well. First Round’s advice on working with advisors, drawn from its partner Phin Barnes, frames it as the founder creating the decision and the advisor acting as editor, with specific and time-bound asks and an honest review of the relationship after a month or two. A good mentor accepts that framing. They ask before they tell. They disagree plainly when they disagree. They say when a question is outside what they know. And they do not take credit for the founder’s success.
Saying no is part of mentoring well. An experienced founder will be asked for more hours than they have. Help fewer founders properly rather than many founders thinly, and when you decline, say so quickly and, where you can, name someone better placed to help. A slow maybe costs a founder more than a fast no.
Honesty includes the hard conversations. A mentor who sees a founder exhausted, isolated or in distress should say so kindly and point them towards help: a doctor or counsellor is the right person to talk to, and Tele-MANAS answers free on 14416 at any hour. A mentor is not a therapist and should not try to be one. Declare conflicts as well: if you have invested in a competitor, or advise one, say so before the founder shares anything confidential.
The giving-back ledger
Keep one page, reviewed every quarter. Money: each cheque, its size, its date and the share of the total portfolio still unwritten. Pace: cheques this year against the plan, so that a busy quarter does not empty the pool. Diligence: hours spent before each cheque, and the one reason you invested. Help: what you promised each founder and whether you delivered it. Mentoring: the founders you are advising, the last time you spoke and one honest line on whether you are still useful to them. No: the requests you declined and why. A founder who keeps this ledger for five years will know whether they have been giving back, or just giving.
Nothing here is legal, tax or investment advice. Angel investing can lose all the money invested; SEBI rules were checked in October 2026.
