Pre-Seed Round

A pre-seed round is early outside funding for a start-up, often used to build a prototype and test demand before reliable sales. It describes a stage rather than a legally fixed instrument. Investors may receive shares or contractual rights to future shares, depending on the financing terms.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

A pre-seed round is an early fundraising stage for a start-up, commonly before it has a mature product or reliable sales, and founders may use it to build a prototype, test customer demand or hire a small initial team. The label describes the company's stage and purpose, not a legally defined security.

One company's pre-seed round might be a priced share sale; another might use a convertible agreement. Before seeking money, identify the next proof point: a software team may need to demonstrate that customers repeatedly use a pilot product, while a hardware team may need a working prototype and manufacturing estimate, and spending should be tied to that milestone.

Potential investors include angels, early-stage funds and sometimes friends and family, and the US Securities and Exchange Commission lists these as possible early-stage funding sources and explains common securities used by start-ups. Not every source is appropriate for every company, so a founder should consider investor suitability, legal offering rules and the effect on personal relationships, since a label like pre-seed does not excuse securities-law compliance.

Funding may take the form of issued equity, a convertible note or a simple agreement for future equity, often called a SAFE, and these instruments do different things. The SEC describes a convertible note as a loan that can convert into another security under agreed conditions.

It describes a SAFE as a promise of future ownership when a triggering event occurs, so the holder does not yet own stock solely by signing that agreement, and terms and jurisdiction matter. In a priced equity round, investors buy shares at an agreed price, and a simple illustration is $400,000 invested at a $4,000,000 post-money valuation, equal to 10% of the company immediately after that financing, assuming a simple capital structure.

A post-money valuation is different from the value immediately before receiving the cash, so confirm which number a term sheet uses, and remember that real ownership can change with options, other investors and later financing. Do not apply that same 10% calculation blindly to a SAFE: Y Combinator explains that a post-money valuation-cap SAFE can make a particular ownership calculation more transparent, but the agreement's cap, discount, conversion mechanics and other financing determine the actual result, so founders should model a cap table under several future financing outcomes rather than quoting one percentage out of context.

A round should include enough cash for a defined period and realistic contingency: estimate monthly net cash burn, then divide available cash by that burn to get an illustrative runway in months, so $600,000 of cash and $50,000 of net spending per month gives a simple runway of twelve months. This is a planning estimate, not a promise of survival, because hiring, product delays and revenue changes alter the result, so keep a monthly forecast and update it as evidence arrives.

Negotiation covers more than the headline amount, so examine the valuation or cap, investor rights, information requirements, future financing provisions and any board or voting terms, because a deal that gives the company runway but removes the founders' ability to operate may be costly. Legal advice is especially important when documents are imported from another jurisdiction, since a familiar template may not fit local company law, tax rules or the actual investor agreement.

In practice

Real-world examples.

1

Example

An angel invests for newly issued shares in a priced early financing. The investment buys a defined percentage of the company at an agreed valuation. The founders and the angel both receive a copy of the updated share register.

2

Example

A small fund invests under a SAFE whose conversion terms require careful modelling. The founders build a spreadsheet that shows ownership under a seed round at a low, medium and high valuation. They share it with the fund so that both sides understand the dilution.

3

Example

Founders budget prototype and user-testing costs against a clear milestone. They set the target as 50 pilot users returning weekly, and plan spending to reach it within the runway. If the milestone is missed, they will decide whether to adjust the product or stop.

Formula

Calculation

In a simple priced equity round: immediate investor ownership = investment / post-money valuation x 100. For $400,000 invested at a $4,000,000 post-money valuation, this is 10%, assuming no complicating rights or capital-structure changes. It is not a universal SAFE formula. Two companion calculations complete the picture. The pre-money valuation is $4,000,000 - $400,000 = $3,600,000, so founders who owned 100% beforehand hold $3,600,000 / $4,000,000 = 90% immediately after the round. Runway = cash / monthly net burn, so $600,000 / $50,000 = 12 months; if hiring lifts the burn to $60,000 a month, runway falls to $600,000 / $60,000 = 10 months.

Case study

Seen in the real world.

This illustrative and entirely fictional case follows Tidewater Apps, an invented start-up with a prototype idea and no repeatable sales. It raises modest pre-seed capital for a six-month customer test. Users favour an unexpected feature, so the team revises its product plan and later decides whether to seek seed funding. No follow-on financing is guaranteed.

Tidewater raised $300,000 and budgeted $50,000 a month, so its simple runway was six months. When the test showed users valuing a different feature, the team spent two of those months rebuilding the prototype, leaving four months to gather evidence for a seed pitch. The founders kept a monthly forecast and told investors early that the plan had changed.

Watch out

Common mistakes.

  • Treating the pre-seed label as a standardised legal instrument.
  • Quoting a fixed ownership stake for a convertible agreement without modelling its terms.
  • Raising cash without a testable milestone and a realistic runway plan.
