AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
A SAFE (simple agreement for future equity) lets you put money into a startup now in exchange for shares later, usually when the company raises a priced round; Y Combinator, which created it in 2013, says it converts into shares automatically at that point. For a Nigerian startup, the first question is which company issues the SAFE: a US holding company, often in Delaware, or the Nigerian operating company, because that decides the paperwork, the currency rules and your US filings.
What a SAFE is, in plain terms
A SAFE is not a loan and it is not shares. It is a contract: you pay the company today, and the company promises to give you shares in a future financing round. Y Combinator publishes the standard forms on its documents page (viewed October 2026) and describes the SAFE as the agreement "that lets investors fund your startup now for shares of stock later".
There is no interest, no maturity date in the standard form and no repayment schedule. If the company never raises a priced round, is sold or shuts down, what you get depends on the specific clauses in your SAFE, so read those sections before you sign.
The terms that decide your share
- Valuation cap
- The highest company valuation at which your money converts. A lower cap means more shares for the same cheque.
- Discount
- A percentage off the price paid by new investors in the priced round. YC offers a form with a discount and no cap.
- MFN (most favoured nation)
- If the company later issues SAFEs on better terms, you can take those terms. YC's uncapped MFN form has no cap and no discount.
- Pro rata side letter
- A separate letter giving you the right to invest more in a later round to keep your percentage. YC publishes US and non-US versions.
- Post-money SAFE
- The current YC form. The cap is measured after the SAFE money, so you can work out the percentage you are buying.
Working out what you are buying
YC's own example is a company raising $1 million and selling 15%, which implies a post-money valuation cap of about $6.7 million. The same arithmetic works for a smaller angel cheque.
Example only. Ngozi, a nurse in Houston, puts $25,000 into a Lagos logistics startup on a post-money SAFE with a $5 million cap. Her expected ownership at conversion is $25,000 / $5,000,000 = 0.5% of the company, before any dilution from the priced round itself and any new option pool. If the priced round values the company below the cap, she converts at the round price instead (or the discounted price, if her SAFE has a discount).
| Cheque (example) | Post-money cap | Ownership at conversion, before round dilution |
|---|---|---|
| $10,000 | $4,000,000 | 0.25% |
| $25,000 | $5,000,000 | 0.50% |
| $50,000 | $8,000,000 | 0.625% |
Which company is issuing the SAFE?
Many Nigerian startups that raise from foreign investors set up a US parent, commonly a Delaware corporation, which owns the Nigerian operating company. Our guide to converting a Nigerian startup to a Delaware holding company explains that structure. If your SAFE is with the US parent, you are investing in a US company and your money goes to a US bank account. The SAFE form was written for US companies, which is where it fits most naturally.
If the SAFE is with the Nigerian company directly, check three things with the founder's lawyer:
- Whether the agreement has been adapted to Nigerian company law, since conversion means the Nigerian company issuing and filing new shares with the CAC.
- How the dollars come in. Under the CBN Foreign Exchange Manual that took effect on 1 June 2026, capital brought in through the official market is registered with an electronic Certificate of Capital Importation, which Pavestones Legal's summary says is issued within 24 to 48 hours of the inflow. The certificate matters later if you want to send dividends or sale proceeds back out. See Certificate of Capital Importation for US investors.
- Who holds the documents, and in whose name, once the SAFE converts.
The US side
Who can invest
Startups often limit SAFE rounds to accredited investors. The SEC's page (reviewed April 2026) defines an accredited individual as someone with net worth over $1 million excluding their main home, alone or with a spouse or partner, or income over $200,000 (or $300,000 jointly) in each of the last two years with a reasonable expectation of the same this year, or a holder in good standing of a Series 7, 65 or 82 licence. Ask the founder which exemption the round relies on and whether you qualify.
Reporting
- A SAFE with a US parent is a US investment and does not by itself create foreign-asset filings.
- Once a SAFE with a Nigerian company converts, you hold shares in a foreign corporation. The IRS lists foreign stock not held in a financial account as reportable on Form 8938 where you pass the thresholds, but not on the FBAR (IRS comparison chart, September 2026).
- If you or US relatives reach 10% of a Nigerian company, Form 5471 categories can begin to apply; see owning 10% of a Nigerian company.
- How a SAFE is treated for tax before conversion is a technical question. Ask a US accountant before the year-end, not after.
What to check first
- Get the exact form: post-money or pre-money, cap, discount, MFN, and any side letter.
- Confirm the issuing entity and look it up on the relevant registry (Delaware or the CAC).
- Read the cap table the founder shares, and ask how many other SAFEs are outstanding.
- Ask how and when conversion will happen, and what you receive if the company is sold first.
- Keep a copy of the signed SAFE, your payment record and any capital importation certificate together.
- Invest only what you could lose entirely. Most early companies do not return money.
Where Pryme fits
Pryme does not arrange startup investments. If you are paying a founder or receiving money back later, a Pryme account holds USD and NGN with local details for each, and Swap shows the rate and fee before you approve a conversion. You can also generate a verifiable statement through VerifyDoc.ai as a record of the payment. This is information, not investment or legal advice.
Questions people ask
What is a SAFE in startup investing?
A simple agreement for future equity: you pay now and receive shares later, usually when the company raises a priced round. It is not a loan and pays no interest.
Can I invest in a Nigerian startup with a SAFE from the US?
Yes, commonly through the startup's US parent company. If the SAFE is with the Nigerian company, ask how it has been adapted to Nigerian law and how the capital importation certificate will be issued.
Do I need to be an accredited investor to sign a SAFE?
Often the startup requires it, depending on the securities exemption it uses. The SEC defines accredited individuals by net worth over $1 million excluding the home, income over $200,000 ($300,000 jointly), or certain licences.
Do I report a Nigerian startup investment to the IRS?
Shares in a Nigerian company can be reportable on Form 8938 above the thresholds, and Form 5471 can apply at 10% or more. A SAFE with a US company is a US investment.
