3one4 Capital is a Bengaluru-based early-stage venture firm that backs Indian startups, and it has teamed up with British International Investment to launch the $15 million IIDEA Fund. Venture money in India still tends to bunch up around metro networks, repeat founder patterns, and a familiar set of categories. That leaves a lot of solid companies outside the usual line of sight. Founded in 2016 by Pranav Pai and Siddarth Pai, 3one4 is using IIDEA as a targeted vehicle for women-led ventures, founders from tier II and tier III cities, and startups working in sectors that don’t always get easy seed capital.
What is the IIDEA Fund and how will it work?
The IIDEA Fund is a focused early-stage pool managed by 3one4 Capital with BII as the sole LP. The corpus is $15 million, or roughly ₹141 crore, and the plan is to back about 10 to 15 startups. Initial cheques will be around $500,000, while the rest of the money will be held back for follow-on rounds. Plenty of seed funds can write the first cheque, but fewer can keep supporting a company when the next round gets hard.
Sector-wise, this isn’t a generic “we invest in everything” fund. IIDEA targets energy transition, agriculture, health, deeptech, and manufacturing. The fund prioritizes founder inclusion. Women entrepreneurs, non-metro founders, and businesses tackling developmental gaps sit at the center of the thesis rather than serving as side bets.
For startups, the product here isn’t software. It’s access. 3one4’s model has long been to stay close to portfolio companies through finance, research, platform, governance, and growth support. Nruthya Madappa’s growth and capital development team works on follow-on fundraising, revenue acceleration, M&A, and exits. So the fund is selling a specific promise: first cheque, sector conviction, and hands-on help after the term sheet lands.
Who built the IIDEA Fund and why does 3one4 matter?
The founding story
3one4 Capital started in 2016 with Pranav Pai and Siddarth Pai as co-founders. The firm was built as an early-stage investor with a research-heavy, close-involvement style rather than a spray-and-pray seed model. A decade later, that original bet has turned into a broader venture platform. IIDEA looks like the firm’s clearest attempt yet to carve out a dedicated inclusion-and-impact lane inside that platform.
Why this team has market fit
Pranav Pai runs investments and portfolio construction as founding partner and CIO. He’s led more than 70 seed and venture investments across India and the US, and he studied electrical engineering at Stanford. That helps explain why 3one4 has stayed comfortable with technical categories instead of only chasing consumer hype cycles.
Siddarth Pai brings a different kind of edge. He’s the firm’s founding partner, CFO, and ESG officer, a chartered accountant, and an active policy voice through the Indian Venture Capital Association and startup-related committees. For a fund like IIDEA, that matters. Inclusion-led investing isn’t only about sourcing founders. It also depends on fund structure, compliance discipline, and knowing how regulation affects early-stage capital.
Nruthya Madappa is central to this launch too. She’s a partner and head of growth and capital development at 3one4, and before joining the firm she founded and ran The CoWrks Foundry, investing in more than 25 companies, and also held leadership roles at Cuemath. Her operating mix of fundraising, growth, and portfolio scale-up makes her a believable person to run a thesis that depends on helping overlooked founders cross the gap from “interesting” to institutionally fundable.
Execution track record and early signals
This isn’t a first-time manager asking the market for trust on vibes alone. 3one4 has backed more than 100 startups and logged 26 profitable exits across its first two funds. Last year it partially exited Kuku FM and generated about 90% IRR with a 38.4x MOIC on that investment. The firm’s portfolio includes AGNIT Semiconductor, smallest.ai, Lumio, Licious, Jupiter, Darwinbox, Raise Financial Services, and Eka.Care.
The new fund isn’t waiting around either. 3one4 has already started deploying the IIDEA Fund and has closed nearly 5 investments so far. That matters. A lot of thematic funds spend months talking about intent; this one is already in market.
Fundraising details and where IIDEA sits against rivals
BII has already committed the full corpus as sole LP, so IIDEA launches fully capitalized instead of fundraising in public. That’s happening while 3one4 is also preparing a much larger fifth fund with a likely target of $225 million for broader early-stage bets across AI and SaaS, enterprise and manufacturing automation, fintech, deeptech, and consumer internet. In plain English: IIDEA is the specialist vehicle. Fund V looks more like the flagship.
Competition is real, but it’s fragmented. Saha Fund has long positioned itself around women entrepreneurs. Avaana is one of the better-known names around climate and frontier innovation. Capital-A focuses on manufacturing and climate. It writes first institutional cheques in the ₹5 crore to ₹12 crore range. IIDEA’s angle is different because it combines founder inclusion and sector neglect in one mandate. Not just women, not just climate, not just deeptech, but the overlap where a lot of founders still struggle to get seen.
Why are investors backing the IIDEA Fund now?
A small, tightly scoped fund can do things a flagship fund usually can’t. It can tolerate categories that take longer to mature. It can spend time on founder discovery outside Bengaluru, Mumbai, or Delhi. And it can write conviction cheques in sectors where early data is thinner but the upside is still real.
That’s why this launch matters for 3one4 itself. Instead of forcing every inclusion bet through the same funnel as mainstream venture software deals, the firm now has a dedicated vehicle with a development-finance LP that wants those outcomes. For BII, the logic is just as clear. It gets exposure to Indian startups through a manager it already knows, while pushing capital toward gender, inclusion, health, agriculture, and climate-linked outcomes that fit its broader mandate.
There’s also a timing benefit. Because the fund is already raised and already deploying, 3one4 can test whether this thesis produces stronger pipelines and better follow-on behavior before its next flagship becomes fully active. That’s smart.
What market trends support the IIDEA Fund?
The numbers show why a fund like this can exist. India tech funding grew from $11.9 billion in FY 2018-19 to a peak of $45.8 billion in FY 2021-22 before the market reset, and women co-founded startups in India accounted for about $1.2 billion in funding in FY 2025-26 — roughly 11% of total startup funding. That’s not trivial. But it’s still a narrow share when you remember how big the overall market is.
There’s a second clue in the stage data. Tracxn says seed funding for women co-founded startups dropped from $280 million in FY 2024-25 to $224 million in FY 2025-26, while early-stage funding rose to $657 million. That usually means investors are still writing checks, but they’re being pickier at the earliest stage. Bain’s 2025 India venture report also pointed to a recovery in activity, with deal volumes rising from 880 in 2023 to 1,270 in 2024. So the market is open again — just not evenly open.
BII’s own priorities line up with that imbalance. In its 2026-31 strategy, the institution said it wants 30% of new core investments to qualify under the 2X Challenge and singled out women’s inclusion, quality jobs in manufacturing and services, and women-linked climate resilience as target areas. That makes IIDEA feel less like a one-off press announcement and more like a practical expression of how development finance wants to show up in venture right now.
Will the IIDEA Fund change who gets funded?
Maybe. But let’s not pretend a $15 million vehicle rewrites Indian venture by itself.
What it can do is prove that underrepresented founders and underfunded sectors aren’t charity cases — they’re investable if the fund design matches the reality on the ground. Over the next 12 to 18 months, the thing to watch isn’t just how many startups it backs, but whether those companies attract strong follow-on rounds from the rest of the market.

FAQ
- What is the IIDEA Fund? The IIDEA Fund is a $15 million early-stage fund launched by 3one4 Capital with British International Investment as the sole LP. It’s aimed at startups in energy transition, agriculture, health, deeptech, and manufacturing, with a clear bias toward women-led ventures and founders from tier II and tier III cities.
- How does the IIDEA Fund work for startups? It works like a dedicated first-cheque vehicle with follow-on capacity. 3one4 plans to back around 10 to 15 startups, start with roughly $500,000 per company, and keep reserve capital for later rounds. It also plugs founders into the firm’s research, platform, governance, and growth support functions.
- Who are the founders behind 3one4 Capital? 3one4 Capital was founded in 2016 by Pranav Pai and Siddarth Pai. Pranav leads investing as CIO and comes from an engineering background at Stanford, while Siddarth runs finance and ESG and is a chartered accountant deeply involved in venture policy through IVCA.
- Why is the IIDEA Fund focused on women-led and non-metro startups? Because that’s still where a lot of India’s venture blind spots sit. In FY 2025-26, women co-founded startups took about 11% of total startup funding, and activity remained concentrated in big metro hubs, which leaves room for a fund built around founder inclusion instead of only pattern-matching old networks.
