Micro-Funds and Solo GPs: The New Early-Stage Investors (and How to Raise From Them)

The investor landscape has changed.

Ten years ago, raising pre-seed or seed meant chasing a handful of well-known VC firms. Today, thousands of micro-funds and solo GPs are writing early-stage cheques. Many of them are former founders, operators, or angels who have raised small funds to invest more systematically.

This is good news for founders. More investors means more options. But it also means understanding a different type of investor with different motivations, constraints, and expectations.

This guide covers what micro-funds and solo GPs are, why they matter for your raise, and how to find and pitch them effectively.

What Are Micro-Funds and Solo GPs?

Micro-funds are venture capital funds that are smaller than traditional VC funds. There is no universal definition, but they are typically in the $5M–$50M range, sometimes up to $100M depending on who you ask. They invest at pre-seed and seed, writing smaller cheques than larger funds.

Solo GPs (General Partners) are individuals who manage a fund on their own, without a larger partnership structure. Many micro-funds are run by solo GPs.

How they differ from traditional VCs:

Traditional VC funds:

• Fund size: typically $100M–$1B+
• Cheque size: typically $1M–$10M+
• Team: multiple partners, associates, analysts
• Decision-making: usually requires partnership vote
• Portfolio: 20–40 companies over fund life
• Stage: often Seed to Series B and beyond

Micro-funds and solo GPs:

• Fund size: typically $5M–$50M (varies)
• Cheque size: typically $25K–$500K
• Team: 1–3 people, often just one
• Decision-making: individual decision, no partnership vote needed
• Portfolio: often 30–80 companies over fund life, with more shots-on-goal than traditional VCs
• Stage: primarily pre-seed and seed

Why Micro-Funds and Solo GPs Matter for Your Raise

1. They fill the pre-seed gap

Traditional VCs have moved up-market. Many funds that used to write $500K seed cheques now write $2M+ cheques. This left a gap at the earliest stages.

Micro-funds fill that gap. They write the $50K–$250K cheques that help founders get from idea to traction.

2. Faster decisions

Solo GPs do not need partnership approval. If they like you, they can move quickly. Decisions often happen faster because there are no partner meetings to schedule. With strong conviction, some solo GPs commit in 1–2 weeks. This is not guaranteed, but the structural advantage is real.

3. Often former founders or operators

Many solo GPs started funds after exiting their own companies or spending years as operators. They have built products, managed teams, and raised money themselves. Their advice tends to be practical, not theoretical.

4. More accessible

Large VC funds receive thousands of cold pitches. Solo GPs often have smaller networks and are more reachable. A warm intro helps, but cold outreach can work.

5. Can lead or follow

Some micro-funds lead rounds (set terms, do diligence). Others prefer to follow an existing lead. Knowing which mode a fund operates in helps you target them correctly.

What Micro-Funds and Solo GPs Look For

Their criteria overlap with traditional VCs but with some differences:

Team: Still the most important factor. Solo GPs often invest in people they want to work with, sometimes even more than traditional VCs.

Market: Must be large enough for meaningful outcomes, but micro-funds can be profitable with smaller exits. A $50M exit that would disappoint a $500M fund can be great for a $10M fund.

Traction: Varies. Some invest pre-product. Others want early revenue. Know the fund's stage focus before pitching.

Thesis fit: Many solo GPs have specific areas they invest in (fintech, developer tools, climate, etc.). Targeting funds that match your space dramatically increases your odds.

Check size fit: A $10M fund writing $100K cheques needs you to be raising a round where that makes sense. If you are raising $3M, their cheque may be too small to matter.

How to Find Micro-Funds and Solo GPs

Traditional VC databases undercount micro-funds. Many solo GPs are not in Crunchbase or PitchBook. Here is how to find them:

1. Twitter/X and LinkedIn

Many solo GPs are active on social media. They share their thesis, announce investments, and engage with founders. Search for "solo GP," "micro fund," "rolling fund," or "emerging manager."

2. AngelList and Rolling Funds

AngelList hosts many rolling funds and syndicates run by solo GPs. Browse by sector or stage.

3. Substack and newsletters

Solo GPs often write about their investment thesis. Finding and reading their content helps you understand fit before reaching out.

4. Fund announcement posts

When solo GPs raise their funds, they often announce on Twitter/LinkedIn. Search "[sector] fund announcement" or look for "excited to announce" posts.

5. Portfolio company founders

Look at who invested in companies similar to yours. Check the cap tables of startups in your space (often visible in press releases or Crunchbase). Reach out to those founders for warm intros.

6. Accelerator networks

If you have been through an accelerator, your alumni network likely includes founders who have raised from micro-funds. Ask for recommendations and intros.

7. Investor databases with micro-fund coverage

Some databases specifically track emerging managers and micro-funds. Platvix includes solo GPs and micro-funds in its 40,000+ investor database, filtered by stage, sector, and geography.

How to Pitch Micro-Funds and Solo GPs

The fundamentals are the same as pitching any investor, with some adjustments:

Do your research

Solo GPs often have specific theses. Read their writing. Look at their portfolio. Reference something specific when you reach out. Generic pitches get ignored.

Lead with fit

Explain why you are reaching out to them specifically. "I saw you invested in [similar company] and wrote about [thesis]. We are building in the same space" shows you did the work.

Be direct about what you need

"We are raising £400K pre-seed. We have £200K committed and looking for investors writing £25K–£50K cheques." Clear asks get clearer answers.

Make their decision easy

Solo GPs have limited time. Send a clean deck, a clear ask, and be responsive. The less friction, the faster they can move.

Ask about their process

Some solo GPs decide in one meeting. Others take weeks. Asking "what does your process typically look like?" helps you set expectations.

Understand their constraints

A $10M fund investing in 50 companies has about $200K per company (including reserves). They may not be able to do $500K cheques even if they want to. Know their typical cheque size.

What to Expect From Micro-Fund Investors

Pros

Accessibility: Easier to get meetings. More responsive.

Speed: Decisions can happen faster than at traditional VCs. Some solo GPs commit within 1–2 weeks when there is conviction.

Operator experience: Many have built companies. Advice is practical.

Founder-friendly terms: Emerging managers often compete on terms since they cannot compete on brand.

Personal attention: With smaller portfolios, they may have more time for you than a partner at a large fund juggling 30 boards.

Cons

Smaller cheques: You may need more investors to fill a round.

Less brand signalling: "Backed by Sequoia" opens doors. "Backed by [unknown fund]" does not. This matters less than it used to, but still matters.

Variable value-add: Some solo GPs are incredibly helpful. Others are purely capital. Ask portfolio founders what their experience has been.

Fund lifecycle constraints: A fund near the end of its investment period may not be able to invest. A brand new fund may still be figuring out their process.

Follow-on uncertainty: Micro-funds often cannot do large follow-on investments. Your Series A lead will likely be a different, larger fund.

Building a Round With Multiple Micro-Funds

Many pre-seed and seed rounds include several micro-fund or solo GP investors rather than one lead. Here is how to manage this:

Secure a lead first

Even with multiple small investors, you typically need one to lead: set terms, anchor the round, and do the most diligence. This could be a micro-fund willing to lead or an angel with credibility.

Stack cheques efficiently

If you are raising £500K and your average cheque is £50K, you need 10 investors. This is manageable. If you are raising £2M with £50K cheques, you need 40 investors. That is probably too many.

Rule of thumb: Try to have at least one investor doing 15–25% of the round. Fill the rest with smaller cheques.

Manage communication

More investors means more updates, more questions, more relationships. Set expectations early about how you will communicate (monthly updates, quarterly calls, etc.).

Use a syndicate or SPV if needed

If you have many small investors, consider rolling them into a Special Purpose Vehicle (SPV) to simplify your cap table. AngelList and other platforms make this easy.

Common Mistakes

Treating all micro-funds the same

Some are pre-seed focused. Some only do seed. Some lead. Some follow. Some are sector-specific. Research before reaching out.

Ignoring cheque size fit

Pitching a $5M raise to a fund that writes $50K cheques wastes everyone's time. Match your round size to their typical investment.

Not asking about reserves and follow-on

Some micro-funds reserve capital for follow-on. Others invest their whole fund in first cheques. Know what to expect for future rounds.

Expecting brand signalling

Micro-funds and solo GPs often cannot open doors the way Tier 1 VCs can. If brand name matters for your business (hiring, partnerships, press), factor that into your investor mix.

Taking too many small cheques

Every investor is a relationship to manage. A round with 25 investors is harder to manage than one with 5. Be selective even when cheques are available.

FAQ

Can a micro-fund lead my round?

Yes. Many micro-funds lead pre-seed and seed rounds. Ask them directly: "Do you lead rounds, or do you prefer to follow an existing lead?"

How do I know if a solo GP is legitimate?

Do your due diligence. Ask for 2–3 founder references from their portfolio and actually call them. Ask how they invest (fund, SPV, rolling fund, or direct). Ask who handles their admin and legal. Check if they have made investments before and whether portfolio founders speak well of them. A legitimate solo GP will have clear answers to all of these.

Should I prioritise micro-funds over larger VCs?

It depends on your round size and what you need. Micro-funds are often more accessible at pre-seed. For larger seed rounds, you may need traditional VCs for larger cheques.

Do micro-funds do pro rata in follow-on rounds?

Some do, some do not. Micro-funds often have limited reserves and may not be able to participate in Series A at meaningful levels. Ask about their follow-on strategy.

How many investors is too many?

There is no hard rule, but managing more than 15–20 investors becomes time-consuming. If your cap table is getting crowded, consider an SPV to consolidate small cheques.

Closing Thought

The rise of micro-funds and solo GPs is one of the best things to happen for early-stage founders.

More capital. More options. More investors who understand what it is like to build something from nothing.

But more options also means more research. Not every micro-fund is right for you. Not every solo GP will be helpful. The founders who raise successfully from this new landscape are the ones who do the work: finding funds that fit, understanding their constraints, and pitching with specificity.

The days of chasing a handful of gatekeepers are over. The new game is finding the investors who are the right fit for your company, wherever they are.
