Category I AIFs: Angel, VC, SME, Infra, Social Funds

When a founder you know sends the angel round's term sheet, or a distributor offers a slot in an infrastructure fund that is closing, you are looking at Category I — the AIF bucket SEBI deliberately regulates lightly because the capital does something policy likes: it funds start-ups, small companies, social ventures and infrastructure. Light regulation is not light risk. This guide walks each sub-category as the rules stand in November 2026, including the part that changed everything in September 2025: angel funds now raise money only from accredited investors.

The category definitions and minimums come from the SEBI (Alternative Investment Funds) Regulations, 2012, and the SEBI Master Circular for AIFs last updated September 7, 2026 — the two documents every Category I pitch must comply with. Our complete PMS and AIF guide covers the framework; this post is the Category I deep dive.

What makes a fund Category I

Category I funds invest in start-up or early-stage ventures, social ventures, SMEs, infrastructure, or other sectors the government or regulators consider socially or economically desirable, and include venture capital funds (including angel funds), SME funds, social venture funds and infrastructure funds. Source: SEBI (AIF) Regulations, 2012, Regulation 3(4)(a); SEBI AIF FAQ. Special Situation Funds were added later as their own Category I sub-category.

The shared structure: close-ended with a minimum three-year tenure (extendable two years with two-thirds investor consent), a scheme corpus of at least ₹20 crore, single-investee concentration capped at 25% of investable funds, and sponsor skin in the game of 2.5% of corpus or ₹5 crore, whichever is lower. Source: SEBI (AIF) Regulations, 2012, Regulations 10, 15; AIF Master Circular, September 7, 2026. Valuations arrive at most twice a year — once every six months, or yearly with 75% investor approval.

Angel funds: the September 2025 rebuild

Angel funds got their own chapter — Chapter III-A of the AIF Regulations, amended and notified September 9, 2025 — and the changes are structural:

• Accredited investors only. Angel funds raise funds only from accredited investors. Funds registered after September 10, 2025 are AI-only from day one; legacy angel funds must get there by March 31, 2027, and in the transition may serve no more than 200 non-accredited investors. Source: AIF Master Circular, paragraphs 8.1.1-8.1.2.
• No schemes at all. Angel funds now invest directly at fund level — no scheme launches, no term-sheet filings with SEBI; they keep internal records instead. Source: AIF Master Circular, paragraphs 8.3.1-8.3.2.
• Crowd size and timing. At least five accredited investors must be onboarded before the first close, and the first close must be declared within twelve months of launch eligibility. Source: AIF Master Circular, paragraphs 8.2-8.2.1.
• Investee rules. Follow-on investments are allowed even in companies that outgrow start-up status, but total investment per investee company — original plus follow-on — cannot exceed ₹25 crore, and each investment is locked in for one year (six months if the exit is a sale to a third party rather than a buyback). Source: AIF Master Circular, paragraphs 8.4-8.5.
• Fair allocation. The manager must disclose a defined allocation methodology in the PPM for distributing deals among consenting investors — no case-by-case discretion — and investors hold pro-rata rights in distributions. Source: AIF Master Circular, paragraphs 8.7-8.8.

Existing angel funds are deemed registered as Category I AIF – Angel Funds, no longer a sub-set of venture capital funds. Source: AIF Master Circular, paragraph 8.9. The practical consequence for you: the old ₹25 lakh angel ticket is gone from the current framework — the entry test is accreditation (income ₹2 crore-plus, or net worth ₹7.5 crore including ₹3.75 crore financial assets, or the combined ₹1 crore income plus ₹5 crore net worth route), and the ticket size is whatever the fund's documents set.

Venture capital funds and the legacy VCFs

Venture capital funds are the broadest Category I label: closed-end pools investing in unlisted, early-stage companies. Funds registered under the repealed SEBI (Venture Capital Fund) Regulations, 1996 continue under the AIF framework with continuing obligations. Source: SEBI (AIF) Regulations, 2012; AIF FAQ. VC funds that want offshore sleeves invest abroad within SEBI's overseas investment limits — at most 25% of investable funds, computed at cost. Source: AIF Master Circular, Chapter 5.

SME funds, social venture funds and infrastructure funds

The other three labels do what their names promise, with the category's shared plumbing:

Source for the category scope: SEBI (AIF) Regulations, 2012, Regulation 3(4)(a) and SEBI's AIF FAQ. Each runs under the same 3-year minimum tenure, 25% concentration cap, ₹20 crore corpus floor and six-monthly valuation regime described above — the difference is the asset, not the plumbing.

A word on the neighbouring label: Special Situation Funds, a Category I sub-category that buys stressed or special-situation assets, are far larger creatures — each scheme needs a corpus of at least ₹100 crore and accepts at least ₹10 crore per investor (₹5 crore for accredited investors; ₹25 lakh for employees and directors). Source: AIF Master Circular, paragraphs 9.1-9.2. If a pitch says Category I but quotes crores-level tickets, you are probably looking at an SSF.

The tax treatment: pass-through, with a character note

Category I funds pass income through exactly as Category II does: the fund pays no tax on capital gains, interest or dividends (Section 10(23FBA)); you are taxed as if you had made the investment directly, with the same character and proportion (Section 115UB); income is deemed credited annually whether distributed or not; and the fund deducts 10% TDS on distributions to residents (Section 194LBB). Source: Income-tax Act, 1961, fetched from incometaxindia.gov.in, 3 November 2026; detailed in our PMS and AIF taxation post.

Character matters most here because the assets are unlisted. Gains on unlisted shares held beyond the long-term threshold arrive at 12.5% LTCG without indexation under the July 2024 capital-gains reset; shorter holdings land at slab rates. Source: Finance (No. 2) Act, 2024, effective for transfers on or after July 23, 2024. A 12-month exit is ordinary income; a 30-month exit is 12.5% — plan your follow-on and exit cadence around the calendar, not just the deal.

A worked example: what the caps mean in rupees

Take a Category I infrastructure fund with a ₹80 crore corpus. The concentration cap limits any one project company to 25% of investable funds — ₹20 crore — so even the fund's flagship position cannot dominate the book. Now the angel version: an angel fund may put at most ₹25 crore in total into any one investee, each investment locked for a year, spread across at least five accredited investors at the first close. And the skin-in-the-game floor on that ₹80 crore infrastructure fund: 2.5% of corpus or ₹5 crore, whichever is lower — ₹2 crore of the manager's own money, held as a real investment rather than a fee waiver.

What goes wrong in Category I

• Angel loss rates are the asset class. Early-stage portfolios are built on power laws: most positions go to zero, a few carry the fund. A 1-year lock-in per deal does not protect against that — diversification across the fund's full pipeline does.
• Six-monthly valuations of illiquid assets. Your statement will show the independent valuer's marks, sometimes a year apart. Do not read interim NAVs as offers to exit.
• The follow-on call. Angel follow-ons come pro-rata from existing investors; opting out dilutes you in the winners. Keep dry powder or accept the dilution knowingly.
• The 3+2 tenure. Infrastructure and SME cycles routinely need the two-year extension. Model your liquidity on five years, not three.
• The transition window. Legacy angel funds may still onboard up to 200 non-accredited investors until March 31, 2027. If you are not accredited and someone offers you an angel ticket today, ask exactly which fund and which transition clause.

The verdict

• The fee-on-committed-capital surprise. Like every close-ended AIF, management fees typically run on committed capital from first close — on a ₹1 crore ticket at 2%, that is ₹2 lakh a year whether or not the money is deployed. Model the drag over the full commitment period before you sign.

Category I is where AIF capital meets policy priorities — and where the risk profile is furthest from anything in our mutual funds guide. The 2025 angel rebuild made the gate explicit: accredited investors, defined allocation, capped exposure, one-year lock-ins. If that matches your balance sheet and your patience, the pass-through tax and the 25% concentration cap make the structure honest. If not, the boring stack still works — and costs a fraction.
