Meridian Capital — Fund IV Open

Your investors
should have
been founders Every one of ours was.

We've built companies, fired people, pivoted products, survived missed payrolls, and rung closing bells. We know what you're going through — not because we read about it, but because we lived it.

Meridian invests at Seed and Series A in deep tech, climate infrastructure, and AI companies. We write first checks of $1M–$12M, reserve 2.5x for follow-on, and stay on your board through IPO or acquisition.

Partner, Meridian Capital

"We don't manage our portfolio. We work alongside it."

— Elena Vasquez, GP

Our Mandate

We don't
pick winners.
We build them.

Most VCs pick a portfolio and hope. We spend the first 90 days after every investment embedded with your team — understanding your go-to-market, your hiring gaps, your first-year risks. We've been operationally useful to every company we've backed.

Our LPs include sovereign wealth funds, family offices, and three former unicorn founders who trust us to find the next generation of defining companies. That network is available to every founder in our portfolio.

Operational Presence, Not Advisory Distance

Our partners average 14 years of operating experience before joining Meridian. When you need tactical help — a VP of Sales hire, a pricing model review, a crisis comms situation — you get a partner, not an associate.

We Lead Rounds, Period

We don't co-invest on someone else's thesis. We write the first check, take the board seat, and own the conviction fully. You'll never wonder where we stand because we always stand first.

Founder Equity Is Sacred

We don't push for anti-dilution provisions, ratchets, or participating preferred that cannibalize founder upside. We win when you win — that alignment is structural, not just language in a pitch deck.

"The question every founder should ask a VC is not 'How much can you write?' It's 'Who answers the phone at midnight when the board is fracturing?' At Meridian, every founder has that number."

Daniel Osei

Managing Partner, Meridian Capital. Former CEO, Gridflow (acq. by Siemens, 2021)

Portfolio

Companies rewriting
the rules of their industries

We've backed 61 companies since 2012. Below is a cross-section — not cherry-picked winners, but a representative picture of the categories where we invest. 12 of these companies have achieved unicorn status. 9 have exited.

AI Infrastructure · Series B

Arcadia Systems

The operating layer for enterprise AI deployment. 400+ Fortune 1000 clients. $310M ARR growing at 180% YoY. IPO filed Q3 2025. Our first check: $2.8M seed, 2021.

Featured

Climate Infrastructure · Series A

Lightwave Energy

Grid-native battery storage reaching cost parity with gas peakers in 2023 — 3 years ahead of consensus forecasts.

Health Tech · Seed

Helix Dx

Lab-quality cancer biomarker panels at 1/8th traditional cost, delivered at point-of-care in 22 minutes.

Industrial Automation · Series A

Kinara Robotics

Autonomous inspection robots reducing industrial downtime by 62%. Deployed in 38 countries.

Mobility · Seed

Vanta Rail

AI-powered predictive maintenance for rail networks, cutting unplanned outages by 74% across 6 national operators.

Investment Thesis

We invest where infrastructure
meets inevitability

Our thesis isn't a list of buzzwords — it's a specific view on where technological capability, cost curves, regulatory tailwinds, and talent convergence are pointing. We've held this view publicly since 2019. Our returns suggest we were right.

PILLAR 01

The Physical World Gets Its Software Moment

Manufacturing, logistics, energy, and agriculture are 80% of global GDP but received less than 8% of venture investment over the past decade. The companies building software-native infrastructure for these sectors will generate the largest returns of the 2020s.

Current Signal: Industrial AI Spend Up 340% YoY

PILLAR 02

Climate Transition Creates the Largest Infrastructure Build in History

$150 trillion in energy infrastructure will be replaced over 30 years. We invest at the stack layer just above hardware — software, services, and marketplace platforms that make clean infrastructure economically obligatory, not aspirational.

Current Signal: IRA Unlocking $3T in Private Capital

PILLAR 03

AI Models Become a Commodity. The Infrastructure Layer Won't.

Foundation models will be cheap in 24 months. The durable businesses are the deployment layer — integration, compliance, orchestration, and workflow AI for industries where generic models can't ship. That's where we focus.

Current Signal: Enterprise AI Infra CAGR at 58%

The Partnership

Built by people who
have done the hard parts

Our four general partners have collectively founded 7 companies, taken 3 public, and led or participated in $4.2B in exits before ever managing a fund. They know what good and bad boards look like from both sides of the table.

Why he invests

"I spent 11 years building things and hitting walls I didn't need to hit. I invest so founders don't hit the same ones."

Daniel Osei

Managing Partner

Fmr. CEO, Gridflow (acq. Siemens $1.1B) · MIT Sloan

Why she invests

"Science moves faster than capital. My job is to make sure the best science gets the runway it deserves."

Elena Vasquez

General Partner — Deep Tech

PhD Materials Science, Caltech · Co-founder, Novacite (IPO 2020)

Why he invests

"The most important markets in the next decade will be built in Africa, Southeast Asia, and Latin America. I make sure Meridian is there first."

Kwame Asante

General Partner — Climate

Fmr. VP Policy, Tesla · Harvard Kennedy School

Why she invests

"I've been the founder in the room with no leverage. I take board seats to make sure our founders always have an advocate."

Nadia Sorel

General Partner — AI & Consumer

Fmr. Head of Product, Stripe · Founder, Comet (Series C)

What We Fund

Checks, Stages,
and What We Need to See

Pre-Seed

Exceptional teams with a credible hypothesis and early technical proof. We don't need revenue — we need to believe you're the right team and the market is real.

$500K–$1.5M

Seed

Product in market, early user signal or signed LOIs, and a go-to-market hypothesis you can defend. Founding team should be complete or near-complete.

$1.5M–$4M

Series A

$1–3M ARR (or equivalent traction), proven unit economics, clear expansion thesis, and a market large enough to justify $1B+ outcomes. We lead. Always.

$4M–$12M

Follow-On

We reserve 2.5x initial investment for portfolio companies hitting milestones. We proactively offer bridge terms when companies need runway, not just when asked.

No limit

Sectors

Deep Tech, Climate Infrastructure, AI Platforms, Industrial Automation, Healthcare Technology, and select Consumer if unit economics are exceptional.

Geography

North America primary, with active sourcing in Europe and Southeast Asia. Our LP base gives us market access in 42 countries — useful from day one.

Global

"The first thing we tell founders: we are not passive capital. If you want a check and no opinions, we are not your firm."

Founding team matters most. We've passed on objectively excellent markets because the team didn't have the capability to win them. We've invested in thin markets because the team could expand them.

Technical moat required. We don't invest in distribution-first businesses at seed. We need to see IP, proprietary data, or a technical wedge that creates durable defensibility.

We don't do spray-and-pray. We have 8–10 new investments per year across the fund. Every founder gets a GP on their board, real operational attention, and access to the full network.

Honest on what we won't fund: consumer social, crypto speculation, ad-tech, or anything with negative social externalities we can't reconcile.

Founder Voice

What founders say when
no one is watching

These are unedited quotes pulled from our annual founder NPS survey (82% response rate, 2024). We publish the full results — good and bad — in our annual transparency report.

Daniel didn't just make intros — he got on calls with our top 5 target customers, gave us intel on exactly how to position, and then stepped back. Three of those became our biggest accounts. That's not VC behavior. That's co-founder behavior.

Marcus Tran

CEO & Co-Founder, Arcadia Systems · $310M ARR

Series B Closed $95M

We burned through cash faster than projected in year two. Most investors would have called an emergency board meeting and started discussing pivot or shutdown. Meridian showed up with a bridge term sheet before I even asked. That's the difference between a partner and a monitor.

Chiara Russo

Founder & CEO, Lightwave Energy · 22 countries

Bridge → Series A → Profitable

Elena's technical credibility opened doors I couldn't have opened in five years on my own. When she's in the room, enterprise buyers treat us like a peer, not a startup. She has access to scientific advisory boards, national labs, and government procurement teams. Completely undervalued by the term sheet alone.

Yusuf Ibrahim

CTO, Helix Diagnostics · 40 hospital systems

FDA 510(k) Cleared 2024

I've taken three rounds across two companies. Meridian's term sheet is structurally different — no participating preferred, no 2x liquidation preference, no ratchets. On paper it costs them on downside outcomes. That's the whole point. They're betting on a win, not hedging against a loss at your expense.

Amara Diallo

Serial Founder · Kinara Robotics, 38 countries

Series A — $28M Led by Meridian

How It Works

Our process is designed for
founder dignity

We've been on the other side of a VC process. We know it's dehumanizing when done poorly. Our process has hard timelines we stick to — and we give honest feedback even when we pass.

Submit & Hear Back Within 5 Days

No cold outreach required. Submit through our site. Every application is reviewed by a GP — not screened by an associate. You'll receive a response within 5 business days: a pass with specific reasons, or an invitation to a first call. We don't ghost.

First Call — One Partner, 45 Minutes

No PowerPoint. We want a conversation about your thinking: the problem you're solving, why now, why you. We'll give you real reactions in real time. If there's interest, you'll know in 24 hours.

We'll ask for 5 references: 2 customers, 2 former colleagues, 1 person who's seen you at your worst. We tell you exactly who we're speaking to. No back-channel references without your knowledge — ever.

Apply for Investment

If you're building something hard and important,
we want to know.

We back companies that others think are too early, too technical, or too hard to explain in an elevator. Those are usually the best ones. If yours fits that description, we are very interested.

✓

Technical founding team with domain depth

At least one founder who can build the core product and one who understands the customer completely

✓

Market that rewards defensibility over distribution

We look for technical or data moats that compound over time, not go-to-market advantages that erode

✓

Honest about what you don't know

We trust founders who clearly articulate their risks more than those who minimize them

Not sure if you fit? Submit anyway. We've invested in companies that didn't match our thesis on paper but whose teams changed our minds in conversation. The worst outcome is a fast, honest "no" with useful feedback.
