A solo GP is a general partner who raises and runs a venture fund alone, holding the investment decision, the LP relationships and the operating load in one person. It used to be the exception. It isn't anymore. 61% of VC Lab managers are solo GPs, and that number comes from managers forming funds right now, not a survey of firms that already exist.
That figure should change how you think about your own fund. The two-partner spinout, two people leaving a bigger firm together and splitting the carry and the sourcing, is no longer the standard shape of fund formation. If you're building alone, you're building the way most new managers build.
The data: the solo GP is the default, not the exception
Start with what we can see. Across 20 cohorts and 950+ VC firms accelerated, VC Lab's manager population is 61% solo GPs, 28% female GPs, and 56% international, spread across managers in more than 90 countries. 85% of them invest at pre-seed or seed.
What makes this data unusual is that it's formation-stage. Most industry numbers describe firms that already raised, reflecting decisions made three to eight years ago against a bar set by an earlier market. Ours describe the funds being built this quarter.
Read it with the other formation trends. Generalist funds fell from 22% of new funds in 2020 to 5% in Q1 2026. Specialists went from 78% to 95%. Managers under 40 rose to 38% of new managers, up from 25%. Those trends and the 61% solo figure are one trend from different angles, cut in full in our generalist versus specialist data analysis.
Here's the connection. A specialist thesis is almost always one person's accumulated expertise: the fifteen years you spent inside industrial robotics, or clinical trial operations, or Brazilian fintech. That edge doesn't survive being averaged with a partner who has a different one. Two specialists in one fund produce either a generalist fund with extra overhead, or a fund where one partner defers on half the decisions. A sharp thesis and a single decision maker fit together.
Why the solo GP model works now
Four things make the model viable now.
Decision speed
At pre-seed the round is often gone in a week. A partnership with a Monday meeting and a consensus norm loses deals by process alone. A solo GP hears a pitch on Tuesday, does the work Wednesday, and commits Thursday. That isn't recklessness if the process is written down and followed. It's a shorter path from conviction to a wire.
No committee, so the thesis stays intact
Every investment committee drifts toward the deal nobody objects to. That's how a sharp thesis becomes a portfolio of reasonable companies. A solo GP's portfolio can be strange in a specific, deliberate way, because there's no second vote to survive. The bets that look wrong to most people are the only ones that produce outsized returns, which is the argument of the power law in venture. A committee filters out exactly those bets.
Lower fixed costs, so a smaller fund is viable
One salary instead of two or three drops the minimum viable fund size. That matters because of where LP money goes: roughly 90% of emerging manager commitments go to funds under $15MM, at an average LP check of $159K. The market funds small vehicles, and small vehicles support one person. Our first fund fundraising statistics has the breakdown.
The back office got unbundled
Formation, capital accounts, capital calls, K-1s and LP reporting used to need a partner who liked operations or a full-time hire. Those functions are now buyable as a service, and 1,000+ firms run on Decile Hub. The work didn't disappear. It stopped needing a person on your cap table.
Demand cooperated too. February through May 2026 ranked among the top five fundraising months in four years, each running 1.2x to 2.2x the same month in 2025, across 1,000+ PACTs, 1,000+ LPAs and 900+ funds. The analysis is in our emerging manager performance data. LPs are actively writing into small, specialised, mostly single-manager vehicles.
Solo GP economics: what a fund size actually supports
This is where first-time managers go wrong, and it's pure arithmetic. A solo GP has one fee stream covering one salary plus every operating cost the fund has. Nothing subsidises it.
The worked example
Take a $10MM fund at a 2% annual management fee, so $200,000 a year. Held flat over a ten year life, total fees are $2MM, or 20% of the fund. Fees usually step down after the investment period, so treat $2MM as a ceiling and $8MM as what you have to invest.
Now the annual cost stack. As a solo GP you pay for fund administration and capital accounts, audit and tax prep, ongoing legal, insurance, software, entity filings, and travel. Suppose you hold that to $70,000 a year on a bundled back office. $200,000 minus $70,000 leaves $130,000 for one salary. Tight, but a real living, and you still own carry on the whole fund.
Run it on a $5MM fund. 2% is $100,000 a year, and the same $70,000 stack leaves $30,000. That isn't a salary. You have four honest options: raise the fee to 2.5%, which gets you $125,000 and leaves $55,000; cut the stack toward zero; keep outside income while the fund proves out; or accept that fund I is a track record vehicle you're subsidising. There's no fifth option where the arithmetic quietly works.
Run it upward and it inverts. A $25MM fund at 2% is $500,000 a year, leaving $430,000 after the same stack. That funds the GP, a first hire and a scout budget. At that size, staying solo is a choice rather than a constraint.
So how small is too small
The threshold isn't a fund size. It's the point where the fee stops covering the operating base plus your minimum income. Take the cost stack you can achieve, add the salary you can live on, and divide by your fee rate. That's your floor. For most solo GPs paying for a real back office it lands in the high single digit millions. We covered the failure modes on both sides of that line in fund size pitfalls in emerging VC.
Portfolio and LP math for one person
Fees aren't the only constraint. Attention is. With $8MM investable, $250K checks buy 32 positions if you hold nothing back. Reserve half for follow-ons and you get 16 initial positions at $250K with $250K of dry powder each. A $250K check at an $8MM post-money is about 3.1% ownership, and the same check at a $5MM post is 5%. Those numbers decide whether your winners can return the fund, and the mechanics are in emerging manager portfolio construction.
Sixteen to thirty portfolio relationships is what one person holds at useful depth, the real ceiling on a solo GP's position count.
The LP side runs the same way. A $10MM fund at the $159K average check is about 63 LP relationships to source, close and report to for ten years. Average $200K in the $150K to $250K band instead and you're at 50. That band also converts to signed LPAs at 1.2x to 2.4x the rate of other bands, so the larger check is less work per dollar and likelier to close.
What actually breaks when you're a solo GP
That's the case for the model. Here's what it costs. LPs will raise every item on this list.
Your sourcing is capped by one network
Two partners with different networks see roughly twice the deal flow. You see what one person can see. In a specialist fund that matters less than it sounds, since depth beats breadth. But it's a hard cap, and it bites in year three, once you've worked through the companies you already knew. Building inbound early is the fix, and our guide to deal sourcing for emerging managers covers the mechanics.
No second opinion on conviction
The committee you removed was doing something useful alongside the damage. It caught the deal you loved for the wrong reason, the founder who reminded you of yourself, the thesis you'd decided on before the meeting. Alone, your blind spots go into the portfolio at full size. It's the most important thing to engineer around, and it doesn't take a partner.
Key person risk is a real diligence item
In a two-partner fund, one person leaving is a problem. In a solo GP fund, you leaving ends the fund's ability to operate. LPs know this and will underwrite it explicitly. It's fair, and it won't go away.
The operational load is larger than you think
Capital calls, capital accounts, K-1s, quarterly reporting, valuation policy, compliance, banking, entity maintenance, side letter tracking. None of it produces returns and all of it has deadlines. In a partnership somebody owns it. As a solo GP it's yours by default, and it eats the hours you meant to spend sourcing.
Isolation is a performance problem, not a mood
Ten years is a long time to make high-stakes decisions with nobody to think out loud with. It shows up as slower calls, avoided hard conversations with founders, and drift on portfolio triage. Treat peer community as infrastructure.
What a solo GP must systematise or outsource
This is the practical core. The model survives ten years only if work that doesn't need you specifically stops touching you.
Fund administration and capital accounts
Outsource this first and completely. Capital accounts, capital calls, distributions, K-1s, audit support and financial statements belong on a service, not in your spreadsheet. It's cheaper than your time, and it moves the fund's financial record off your laptop, which is half of your key person answer. Decile Partners exists for this, and its cost should be a line in the arithmetic above from day one.
One system of record for pipeline and LPs
The most common solo GP failure isn't a bad investment. It's a fund run across a personal inbox, three spreadsheets, a notes app and memory. That works until somebody else needs to see it, which is exactly the day you can't show them. Pick one system for deal pipeline, diligence notes, decisions, portfolio data, LP records and reporting, and put everything in it. Decile Hub is what the firms in our network use. The tool matters less than the discipline that there's exactly one.
A written investment process that exists outside your head
Write down what you invest in, what you don't, the diligence steps every company goes through, who you call for domain references, your check and reserve rules, and the reasons you'll pass. Then follow it and record each decision, including passes.
That does three jobs. It's the second opinion you gave up, since a written standard catches the deal you're excited about for reasons that don't match your criteria. It's what an LP reads to decide whether you have a process or a habit. And it's what someone else could execute if you couldn't. Our guide to early stage diligence is a reasonable template to adapt.
A scout and advisor layer
You can extend one network without adding a partner. A scout group of five to fifteen people deep in your domain buys sourcing reach for a modest economic arrangement, or simply for access and standing. A short list of advisors you can call for a technical read gives you a real second opinion without giving anyone a vote.
Scouts and advisors inform the decision. You still make it. That keeps the speed and thesis integrity while patching the two things that break.
How LPs diligence a solo GP
LPs run the same three checks on a single-manager fund, whether or not you raise the subject.
Is the edge real and is it yours
They're testing whether your sourcing advantage comes from a specific position in a specific market or from general enthusiasm. The specialist shift helps here. A thesis that's clearly one person's fifteen years reads as more credible from a solo GP than from a partnership, because there's no ambiguity about whose expertise drives the fund. Bring proof: companies you've helped, people who route deals to you, deals you saw first.
The key person provision
Your LPA will name you as the key person. The clause typically triggers on death, disability, departure, or failure to devote substantially all your business time to the fund, and the standard consequence is automatic suspension of the investment period until LPs vote to resume or wind down. Read the trigger language before you sign. A clause that fires on any outside role becomes a problem in year six.
The bus question
"What happens to my capital if you get hit by a bus" is a fair question with a real answer, and a vague one costs you the check. A credible answer has five parts. A named successor or transition manager, ideally someone the LPs have met, documented rather than implied. The fund's books and capital accounts held by an administrator, so nothing critical dies with your laptop. Board seats, pro rata and information rights held by the fund entity, not by you personally. An advisory board or LPAC with a defined path to appoint replacement management. And key person insurance where the fund size justifies the premium.
Four of those five are things you'd do anyway if you were systematising properly. The bus answer isn't a document written for diligence. It describes a fund already built to run without you touching every part of it. The rest of what LPs check is in our LP due diligence checklist, and getting to a first close is covered in decoding first closes.
When a solo GP should not stay solo
Four signals that the model has stopped serving you.
Fund size crossed the line where fees support a team. Once fees comfortably fund a second person, staying solo means choosing less coverage than you're paying for.
Your portfolio count passed what you can service. If you can't recall the state of every company without opening a file, you're not delivering the support you sold founders.
Your thesis widened past your expertise. If fund II covers three sectors and you're expert in one, you've become a generalist with a solo decision process, which combines the weaknesses of both.
Sourcing went flat. If deal quality is falling and scouts haven't fixed it, the constraint is network reach, and a partner with a different network is the direct fix.
None of these are failures. Going from solo GP to a small partnership is a normal fund II or III step, and Emerging Institute is built for managers on funds II through IV working through it. If you're earlier and want to see how the small end of the market is structured, start with venture capital micro funds.
Frequently asked questions
What is a solo GP in venture capital
A solo GP is a general partner who raises and manages a venture fund alone. They own the investment decision with no partner vote, hold every LP relationship, and carry the operations, though most outsource administration. They're the sole named key person in the LPA. It's the most common shape in fund formation today: 61% of VC Lab managers are solo GPs, across more than 90 countries.
How much money does a solo GP make
It depends on management fees minus operating costs. A $10MM fund at a 2% fee produces $200,000 a year gross. Subtract fund administration, audit and tax, legal, insurance, software and travel, and what's left is salary. On a $5MM fund the fee is $100,000 a year, which usually leaves too little to live on. The real upside is carry, years later, if the portfolio works.
Can one person really run a venture fund
Yes, and most new managers now do. What makes it work is subtraction. Fund administration goes to a service, pipeline and LP records go to one system, and the investment process gets written down so it exists outside your head. What stays with you is sourcing, decisions, founder support and LP relationships. The version that fails keeps all four plus the back office on one desk.
What is the minimum fund size for a solo GP
There's no fixed number, but you can calculate yours. Add the annual operating cost stack you can realistically achieve to the salary you can live on, then divide by your fee rate. That's your floor. For a manager paying for professional fund administration it typically lands in the high single digit millions. Below that the fund works only with outside income, a higher fee, or a decision to treat fund I as a track record vehicle.
Do LPs invest in solo GP funds
They do, at scale. Roughly 90% of emerging manager commitments go to funds under $15MM, the band solo GPs occupy, and the average LP check is $159K. Checks in the $150K to $250K band convert to signed LPAs at 1.2x to 2.4x the rate of other bands. LPs will underwrite key person risk explicitly, so come with a named successor, an outsourced administrator, and a written process.
Start your fund
If 61% of new managers are solo GPs, the question isn't whether the model is credible. It's whether yours is built to survive ten years without a partner covering for you. That comes down to the arithmetic on your fee, the process you wrote down, and the work you moved off your desk.
VC Lab is the free accelerator for first-time and emerging managers, and its cohorts are where that 61% comes from. It takes you through fund formation, LP strategy and first close. To run a small first vehicle and build a track record before raising something larger, Start Fund is designed for that path. The data behind all of this lives in our VC research hub.
Apply to the next VC Lab cohort and build it alone, properly.
