The Idea That Sounds Perfect for Both Sides

An early-stage founder has no development budget but has an idea and equity to give. Hence the question we hear constantly: will an engineering firm build the product in exchange for a percentage of the company instead of cash? On paper it reads as a win-win — the founder gets development without money, the firm gets a slice of something potentially valuable. In practice the model works only under fairly specific conditions, and signed carelessly it is one of the faster ways to complicate a young company. Here is the honest version, from both sides of the table.

This is general educational material written from an engineering firm's point of view on how such arrangements are structured. Projects House is an engineering company — not a law firm, an accounting firm, or an investment adviser. Equity compensation carries securities and tax consequences; work with a startup attorney and a CPA before agreeing to anything described here.

Why Most Engineering Firms Will Say No

An engineering firm lives on cash flow. Engineer salaries, equipment, components, and subcontractors are paid in real dollars every month. A full hardware development program can represent a six-figure amount of labor, and shares in an idea-stage venture do not make payroll. Beyond that, a firm holding equity in dozens of client ventures effectively becomes an investment fund without the mandate or the ability to manage the portfolio — and its accountants have to value each position.

So the market norm remains payment for work, with payment structures designed to be easier on founders: milestone billing, staged phases, and tightly scoped first engagements. Those structures are described in product development contract terms. A firm that says no to equity is not being unhelpful; it is telling you its cost base is real.

When It Does Happen

  • The hybrid: a discount in exchange for equity. The realistic structure. The founder pays most of the cost in cash — often the majority of it — and the remainder converts into a small equity position or options. The firm covers its out-of-pocket costs; the founder conserves cash.
  • Future success instead of shares. A royalty on sales, or a bonus at a commercial milestone. Legally simpler, no effect on the cap table, and much easier to unwind. The clause mechanics resemble those in invention license agreement clauses.
  • A venture with proof. When there are already purchase orders, a paying pilot, or a lead investor, the firm's risk drops and its willingness rises sharply. Equity for services is a risk-priced decision, and evidence lowers the price.
  • A genuine strategic reason. Occasionally a firm wants exposure to a category, or the product uses capability it wants to develop anyway. This is rare and it is worth asking about directly rather than assuming.

The Risks to You — Because It May Not Be a Bargain

  • Early dilution is the most expensive dilution. Percentages given at idea stage are the costliest equity you will ever issue. Handing over a double-digit stake for development can weigh on every subsequent round — the arithmetic is in equity dilution explained.
  • A passive holder on the cap table. Future investors dislike seeing a service provider holding a meaningful stake with no ongoing contribution. It comes up in nearly every diligence process, and cleaning it up later costs negotiating leverage.
  • Misaligned incentives. When your developer is also a shareholder, replacing them for poor performance becomes far harder, because you are now bound legally as well as commercially.
  • Ambiguity around intellectual property. When there is no full payment, it becomes critical to state explicitly that all development output belongs to the company — as explained in who owns the IP in a development project. Equity is not a substitute for a written assignment.
  • Valuation and tax questions. Issuing equity for services has tax consequences for both parties in the United States, and it forces you to put a value on a company that may not have one yet. This is where a CPA earns their fee.

If You Do It Anyway, Put This in Writing

Define precisely which scope of work the equity buys, and what happens if the project stops midway. Vest the shares against engineering milestones rather than granting them in full on the day of signature. Secure full transfer of ownership over files, documentation, and any tooling. Confirm the firm has no veto over business decisions and no board seat unless you deliberately intend that. Add an exit mechanism — a repurchase option at an agreed price — in case you later want to clean up the cap table ahead of a large round. And make sure the agreement is reviewed by a lawyer who works on investment documents, not only on service contracts. Understanding how the whole table fits together first is worthwhile: see what a cap table is.

The Bottom Line

Development for equity is a legitimate but uncommon tool, best suited as a complementary component — a discount for a small stake — rather than a full substitute for a development budget. In most cases the better path is dedicated funding: non-dilutive federal grants such as SBIR and STTR awards, which fit engineering-stage work unusually well and are surveyed in our government funding guide, or a proper private round, covered across our hardware startup funding guide — and then paying for development as a client with full control.

Before you offer percentages, find out what the first stage actually costs. Founders frequently discover that a properly scoped initial prototype is more affordable than they assumed, especially when the scope is limited to answering one question.
