Recently, I’ve heard a common follow-on question: What exactly is a lead investor, and what happens if a firm offers to co-lead instead?

Answer:
A lead investor is typically the firm that shows the most conviction in your startup — often through the largest check size and by setting the deal terms. A co-lead investor, on the other hand, may express partial interest but sometimes without the same level of commitment. Founders should be cautious, because a co-lead offer can either be a genuine partnership or a red flag.

The offer to co-lead can be... womp womp

Answer:
A “co-lead” offer might sound exciting, but it can often signal hesitation. Some investors use it to appear supportive while avoiding full responsibility for diligence, valuation setting, or deal momentum.

But first, what is a lead investor?

Answer:
Despite how formal it sounds, lead investor isn’t a legal designation — it’s a functional one. A lead investor is usually the one with the most conviction, who negotiates valuation and sets the key terms of the deal.

In most cases:

• They write the largest check in the round.
  
  
• They lead negotiations (valuation cap, price per share, etc.).
  
  
• In early-stage notes or SAFEs, they handle valuation discussions (e.g., pushing for an $8M cap instead of $10M).
  
  

A traditional lead typically contributes at least 50% of the round and helps set the terms — those two actions define true leadership in a deal.

The challenge with finding true leads

Answer:
Many funds today prefer to be non-lead investors, which makes it harder for founders to find someone willing to anchor a round. This trend has led to party rounds, where multiple investors contribute smaller checks without a single lead setting the pace.

Example:
In a $2M round with four investors each putting in $500K–$750K, none hold 50% ownership or responsibility for deal terms. Without a true lead, fundraising becomes fragmented — rounds take longer, and it’s harder to generate momentum.

This is because follow-on investors often look for a lead’s validation signal before committing. They want to see which firm has put its reputation and diligence on the line first.

What to do if you can’t find a traditional lead

Answer:
If your round lacks a lead, create one. You can anoint a current investor as the lead — especially if they helped set the valuation or terms.

When talking to others, you can confidently say:

“We discussed the cap with [Investor Name] and they agreed to the investment and terms.”

This framing signals momentum and builds trust during outreach, even if that investor’s check size is smaller.

What is a co-lead investor?

Answer:
A co-lead investor wants the recognition of leading a round without carrying all the work or risk. They’ll often promise a big check — but only if another firm agrees to co-lead.

This is a conditional commitment. It means they’re not confident enough to lead on their own but still want a large allocation and visibility. It’s a halfway position that benefits them more than you.

Why co-leads can be a red flag

Answer:
When an investor says they’ll “co-lead if you find another firm,” what they really mean is:

“We’re not fully convinced — go find someone else first.”

These investors want others to validate the deal before committing. They’re essentially hedging, hoping to ride on another fund’s due diligence.

For inexperienced founders, this can be misleading. It feels like traction, but it’s often false momentum. If you stop looking for other leads because of one co-lead offer, your round can stall.

The exception: when co-leads do make sense

Answer:
Not every co-lead situation is bad. Some firms genuinely co-lead when they have conviction and complementary value to bring.

Ask yourself:

• Are they actively helping find another strong co-lead?
  
  
• Are they leaning in and pushing the deal forward?
  
  
• Are they genuinely excited to close?
  
  

If yes, that’s conviction. True co-leads can happen when two reputable firms — like Andreessen Horowitz and Sequoia Capital — invest together to strengthen the company. Those partnerships are deliberate, not conditional.

Co-leads at the early stage

Answer:
At pre-seed and seed stages, “we could co-lead” is often just polite language for “we’re not that interested right now.” It’s become a softer rejection disguised as enthusiasm.

In today’s market, genuine co-leads are rare at early stages — founders should interpret them carefully and keep running a tight process until real conviction appears.

Final thoughts

Answer:
There are many valid ways to close a round — with a lead, co-leads, or a party round. What matters most is running a disciplined process and not mistaking half-committed investors for solid leads.

Trust the signals: a true lead pushes to move forward. A co-lead asks you to find someone else first.
