Demo day investor list: who to invite and how many

Six weeks before demo day, most incubation managers face the same problem: a cohort ready to pitch and a spreadsheet of investor names that is half stale. Some contacts have left their funds, some never invest at this stage, and some have not opened an email from the incubator in two years.

This guide covers how to build the investor invite list for a cohort demo day: where to source names by stage and sector, how big the room should be, how to turn replies into confirmed seats, and how to track who came and who followed up.

What is a demo day investor list?

A demo day investor list is the working list of investors an incubator invites to see its cohort pitch, sorted by the stage and sector each one actually funds. It is built for one event and one cohort, then checked after the day against who attended and who asked for meetings.

It is not the same as the incubator's long-term investor network, which takes a year or more to build, as our guide to building an incubator investor network explains. The list is the slice of that network, plus new names, that fits this particular cohort.

So start from the cohort, not the contacts. Write down each startup's sector, stage and likely round size. Then look for investors who have written cheques of that size, in that sector, in the last year or two.

Where should an incubator find investors by stage and sector?

Source investors from four places: SEBI's register of alternative investment funds, including angel funds; angel networks; alumni founders who now invest; and corporate venture arms in the cohort's sectors. Then filter every name by stage, sector, cheque size and recent activity before it goes on the list.

• SEBI's AIF register. SEBI's list of registered alternative investment funds showed 2,071 records when checked in November 2026, with registration numbers and, for most, a contact person and email. The registration number shows the category, so Category I funds carry "AIF1".
• Angel funds. Angel funds are a type of Category I AIF. They had raised commitments of Rs 11,527 crore by 30 September 2026, according to SEBI's AIF statistics. Invite the person who runs deal flow, not just the fund's name.
• Angel networks. Networks screen startups together and then members decide one by one, so one invitation can reach many cheques. Our explainer on angel networks in India covers how they differ from funds and syndicates.
• Alumni investors. Founders from earlier cohorts who have raised well or exited often write small cheques and know what the programme gives founders. They are also the easiest seats to confirm.
• Corporate venture arms. Companies that invest or run pilots in your cohort's sectors can be the most relevant people in the room for two or three startups, even if they ignore the rest.

Rules shape who can invest. SEBI's September 2025 circular says angel funds raise money only from accredited investors and caps one fund's total investment in a company at Rs 25 crore. Our explainer on angel funds and AIFs sets out what that means; this guide is not investment advice.

Referrals beat databases. In a survey of 885 VCs, over 30 percent of deals came through professional networks and 20 percent were referred by other investors, while only 10 percent came inbound, according to the NBER summary of the study. That is global research, but the lesson travels: ask every confirmed investor who else should be in the room.

How many investors should you invite to a demo day?

Size the room from the cohort. Decide how many relevant investors each startup should meet, multiply by the number of startups, allow for investors who cover several startups, then send more invitations than you have seats. A small room of the right investors beats a full hall of the wrong ones.

The ratio that matters is relevant investors per startup, not total attendance. A fintech startup gains nothing from a row of investors who only back deeptech. The table shows the arithmetic for one cohort; the figures are a planning sample, not a benchmark.

Sample: one cohort	Figure	How it is set
Startups pitching	10	The cohort
Relevant investors wanted per startup	4	Your target for meetings
Investor seats to fill	30	10 times 4, less investors who fit several startups
Confirmations to hold	40	Seats plus a buffer for drop-outs
Invitations to send	80	Confirmations plus room for declines

Scale varies widely. Y Combinator says its invite-only Demo Day has an audience of about 1,000 investors and media, and that investors are invited based on their recent investment history in its companies, per its Demo Day FAQ. That is a global outlier, but the selection rule, recent relevant cheques, works at any size.

How do you turn invitations into confirmed seats?

Invite each investor personally, naming the startups that fit their stage and sector, then confirm twice: once when they register and again a few days before the event, with the final startup profiles attached. An investor who has read the profiles arrives knowing whom to meet.

Use a registration form that asks for stage, sector, cheque size and the startups the investor wants to meet; the incubator demo day registration form template sets out those fields. Our guide on getting investors to attend startup events covers the wording of the invitation itself.

Keep a waitlist sorted by sector. When a confirmed investor drops out, offer the seat to the next investor in the same sector, so no startup loses its only relevant listener the night before.

Build the list from the cohort outwards: every startup should know which investors in the room came for it.

How should you track who came and who followed up?

Track four fields for every investor: invited, confirmed, checked in and followed up, with the startups each one asked to meet. After demo day, chase meeting requests within days and record which led to second meetings and term sheets. That record is what makes next year's list stronger.

Check-in data is the only reliable attendance count, because registrations overstate who turns up. Log meeting requests against each startup during the event, then send each startup its list the next morning. Our guide to what investors want from a demo day covers the profiles and data rooms investors expect afterwards.

The record also serves funders. The Startup India Seed Fund Scheme guidelines ask incubators to record angel or VC funding raised by every beneficiary startup, and assess incubators partly on how many startups raised follow-on investment.

After the event, sort investors into three groups: came and asked for meetings, came but stayed quiet, and declined. Invite the first group first next time, ask the second what was missing, and drop names that declined twice. Collect only the investor data you need, and say how you will use it.

Questions

How many investors should attend an incubator demo day?

There is no official number. Work it out from the cohort: decide how many relevant investors each startup should meet, multiply by the number of startups, allow for investors who cover several startups, then send more invitations than you have seats, because some invitees will decline or drop out.

Where can an incubator find investors for demo day in India?

Start with SEBI's public register of alternative investment funds, which lists registered funds with contact details, then add angel networks, alumni founders who now invest and corporate venture arms in your cohort's sectors. Filter every name by the stage, sector and cheque size it has funded recently.

Should an incubator invite angel investors or VCs to demo day?

Invite whoever funds the cohort's stage. Pre-seed and seed startups usually need angels, angel funds and early-stage funds; later startups need larger funds. Mixing both is fine if every startup has several relevant investors in the room and each investor knows which startups fit them.

How do you track investors after demo day?

Keep one row per investor with four fields: invited, confirmed, checked in and followed up, plus the startups each asked to meet. Update it as meetings, second meetings and term sheets happen. Funders such as the Seed Fund Scheme ask incubators to record funding raised by their startups.
