The distinction sounds like plumbing. It decides where the money goes, and that turns out to matter to almost everyone at the table.
Primary: the company issues new shares
In a primary round the company creates and sells new shares, and the proceeds land in the company's bank account. Existing holders are diluted, and the business has capital to spend on the plan it just described. Every founder raising to build something is running a primary round.
Secondary: existing shares change hands
In a secondary, an existing shareholder sells their shares to a buyer. No new shares are created, and the company receives nothing. The cap table changes names, the balance sheet does not move. Secondaries are how early employees and long held founder stakes turn into cash before an exit.
Both are legitimate. What matters is knowing which one you are being offered, because the risk you are taking is different in each.
Why the difference matters to an angel
- In a primary, your capital funds the milestone that is supposed to create the return. The company's plan and your money are the same thing.
- In a secondary, your capital pays a shareholder for their exit. The company's runway is unchanged the day after you invest.
- Secondaries in private companies frequently carry less information: the buyer often has no rights to financials and no access to the company at all.
- Pricing is negotiated between the buyer and the seller, not set against a round, so anchoring is harder.
Why the difference matters to a founder
Secondary activity you did not authorize can put people on your cap table that you never met and cannot easily reach. Most well drafted early stage documents give the company a right of first refusal and require board consent on transfers. Use them. A clean, known cap table is an asset in every future round.
Founder secondaries at a later stage are common and reasonable. The judgment call is timing and proportion: selling a modest slice at a round where a new investor is happy to buy is very different from repeatedly selling into an unpriced market.
Reading a deal you are offered
- Ask directly whether the proceeds go to the company or to a selling shareholder.
- If it is a secondary, ask who is selling and why. The answer is information.
- Check what you actually receive: shares, an interest in an entity that holds shares, or a contractual right.
- Confirm the transfer is permitted under the company's documents and that the company has consented.
AngelFlow is a primary rounds platform, so members are always looking at the first case: money into the company, funding the next stretch of the plan. That is a deliberate constraint, and it makes the diligence question simpler for everyone involved.
