Incubator

How an incubator works

The United States Economic Development Administration defines a business incubator as a program, often sponsored by a university or nonprofit organization, that provides support and guidance to start-up companies during the embryonic phases of their development to support job creation and retention. The support it names includes technical assistance, facility access, financing, mentorship, and networking.

Two features of that definition carry the weight. The stage is embryonic, meaning pre-product and often pre-incorporation. And the sponsor is frequently a university or nonprofit with a mission, which is why many incubators take no equity at all.

Sponsor type does not separate the two categories, because the EDA describes accelerators as often sponsored by a university or nonprofit organization as well. Duration and structure do. The EDA defines an accelerator as a program that works with entrepreneurs and start-up companies for a short and defined timeframe to help them reach the next phase in their growth. The SBA Office of Advocacy, building on work by Cohen and Hochberg, goes further, defining accelerators as business entities that make seed-stage investments in promising companies in exchange for equity as part of a fixed-term, cohort-based program, including mentorship and educational components, that culminates in a public pitch event or demo day. On the same research, incubator engagements average over three years against a three-month average for accelerators, and incubators have no cohort structure. An incubator has no required cohort, no required end date, and no required investment.

Where an incubator does take equity, the arithmetic is the same as any other issuance:

Incubator ownership = shares issued to the incubator ÷ fully diluted shares outstanding after the issuance

If the incubator's consideration is services rather than cash, the shares are still compensation, which has tax and accounting consequences for the company and for the recipient, and the board still has to determine the fair market value of what it is issuing.

The models in common use are distinct enough to be worth separating.

• University and research incubators. Attached to a technology transfer office. The defining term is usually not equity but the license to the underlying intellectual property, with a royalty, a field-of-use restriction, milestones, and sometimes a reserved equity stake for the institution.
• Nonprofit and economic development incubators. Funded by grants and by public economic development programs. Typically no equity, subsidized space, and eligibility conditions tied to location, sector, or founder demographics.
• Corporate incubators. Run inside a large company to explore adjacent markets. Space and expertise are real, and so are the strings: rights of first refusal, exclusivity, non-competes on the sponsor's market, and information rights that can complicate a later financing or an acquisition by a competitor.
• Venture studios, sometimes described as incubators. A studio originates the idea, supplies founding team members, and takes a founding stake, commonly far larger than an accelerator's, because it did the work of starting the company. This is a different transaction and should not be evaluated against accelerator terms.
• Co-working with programming. Space and events, no capital, no equity. Useful, but the word incubator here describes a real estate product.

Worked example

Suppose a two-person team joins a university-affiliated incubator to commercialize research. These figures are hypothetical.

The incubator provides eighteen months of wet lab and desk space valued at 4,000 dollars a month, access to shared equipment, and a 50,000 dollar non-dilutive grant from a state economic development program administered through the incubator. It takes no equity. The technology transfer office licenses the underlying patent to the new company.

Step one, value the in-kind support. Eighteen months at 4,000 dollars is 72,000 dollars of space, plus 50,000 dollars of grant, or 122,000 dollars of value with no dilution.

Step two, price the license instead. The license carries a 3 percent royalty on net sales, a 25,000 dollar annual minimum starting in year four, milestone payments of 100,000 dollars on first commercial sale and 250,000 dollars at 5 million dollars of cumulative revenue, and 20,000 dollars of patent cost reimbursement.

Step three, model the real cost at scale. At 20 million dollars of annual net sales, the 3 percent royalty is 600,000 dollars a year, every year, before any profit. That is the price of the arrangement, and it does not appear anywhere on the cap table.

Step four, compare with an equity-taking program. An accelerator taking 7 percent for 125,000 dollars costs 7 percent of the exit, once. On a 100 million dollar exit that is 7 million dollars, paid at the end. The royalty is paid from revenue whether or not there is ever an exit, and it reduces the margin a strategic acquirer is buying.

Step five, the actual comparison. The question is not equity versus no equity. It is the present cost of the license and any field-of-use restriction against the value of the space, the grant, and the access, and whether the restriction narrows the set of acquirers. Founders comparing programs on dilution alone systematically misprice university arrangements.

Where it shows up

The participation or membership agreement is the operative document for the program itself. It covers term, space, services, confidentiality, what happens to work product created on the premises, and the conditions for exit from the program. It is often the only document, because many incubators take no securities.

A license agreement with a university technology transfer office is where the real economics of a research incubator sit: field of use, exclusivity, royalty rate, minimums, milestones, diligence obligations, patent cost reimbursement, and termination.

Where the incubator does take a stake, it is documented like any other early investment: a SAFE or a convertible note for a cash investment, or a restricted stock purchase agreement or warrant where the consideration is services. Equity issued for services is compensation, which brings Section 409A, Rule 701, and the board's fair market value determination into scope.

A sponsor-specific agreement appears in corporate incubators: a commercial agreement, a right of first refusal or right of first negotiation on an acquisition, a data or API access agreement, and sometimes exclusivity in a defined market. These terms reach into later financings and should be reviewed by counsel before signature, not before the Series A.

Grant agreements from public economic development programs carry their own conditions: reporting, job creation targets, geography, matching requirements, and clawbacks.

The cap table records the result if any securities were issued, and the program appears in later diligence, where investors will ask for every agreement signed with it.

Common mistakes

• Calling a cohort program with a demo day an incubator. On the SBA Office of Advocacy's definition, a fixed-term, cohort-based program that makes seed-stage investments for equity and ends in a public pitch event is an accelerator, and the EDA's own accelerator entry already turns on a short and defined timeframe.
• Evaluating the offer on dilution alone. At a university incubator, the license terms usually cost more than any equity stake.
• Signing a corporate incubator agreement without checking the exit terms. A right of first refusal or an exclusivity clause can reduce the number of plausible acquirers, and both are discovered by the next investor's counsel.
• Ignoring the ownership of work product. Agreements vary on inventions created using program facilities, and a claim over core intellectual property is a diligence problem that does not go away.
• Treating equity for services as free. It is compensation, with valuation, tax, and securities law consequences.
• Expecting an incubator to function as a signal. Programs with no cohort and no demo day produce no market moment, which is often precisely why they suit a company that is not ready to be looked at.
• Staying too long. Subsidized space has a way of extending the period before a company has to survive on its own revenue or raise from someone with no mission to serve.

Related terms

An incubator sits one step earlier than an accelerator, and the two are frequently conflated. Companies in either usually go on to raise a pre-seed or seed round, often from an angel investor, and where the incubator does invest it typically does so on a SAFE rather than through a priced equity financing.

Frequently asked questions

What is a business incubator?

A program that supports companies at the earliest stage of development with space, technical assistance, mentorship, networks, and sometimes financing. The United States Economic Development Administration describes it as a program, often sponsored by a university or nonprofit organization, that supports start-up companies during the embryonic phases of their development to support job creation and retention.

What is the difference between an incubator and an accelerator?

Structure and stage. The EDA describes an accelerator as a program that works with entrepreneurs for a short and defined timeframe, and the SBA Office of Advocacy defines accelerators as fixed-term, cohort-based programs that make seed-stage investments for equity and culminate in a public pitch event or demo day. Incubators have no required cohort, no defined end date, and frequently take no equity, and they work with companies that are earlier, often pre-product or pre-team. On the SBA's research, incubator engagements average over three years against about three months for an accelerator.

Do incubators take equity?

Many take none, particularly those sponsored by universities, nonprofits, and public economic development programs. Where an incubator does take a stake, it is documented as a SAFE, a convertible note, restricted stock, or a warrant. At university programs the more significant economics usually sit in the intellectual property license rather than in equity.

How long does a company stay in an incubator?

There is no standard term, which is the defining characteristic. Engagements run from months to years and end when the company raises, outgrows the space, or reaches a milestone in its agreement, rather than on a scheduled demo day.

Are incubators worth the cost?

The answer depends on what is actually being exchanged. Price the whole package: the equity if any, the royalty and field-of-use restrictions in any license, exclusivity or acquisition rights granted to a corporate sponsor, and the ownership of work product, against the value of the space, the capital, the technical access, and the introductions. Several of those costs never appear on a cap table.

What is a venture studio and is it the same thing?

A venture studio originates the company idea itself and supplies founding team members, then takes a founding equity stake that is typically much larger than what an accelerator or incubator takes. It is a different arrangement from supporting a team that arrived with its own company, and comparing the two on dilution alone is misleading.
