Carta vs Forge For A Licensed Engineering Firm

Many states require a majority of a professional engineering firm's ownership to sit with licensed engineers, a rule that shapes the Carta-versus-Forge decision before price or buyer reach even enters the conversation. Score your firm against these four criteria before choosing a platform.

Criterion One: Who Is Legally Allowed To Buy

Before anything else, confirm your state's professional engineering ownership rule and how much non-licensed ownership, if any, it permits. A firm at or near its licensed-ownership floor has a much narrower legal buyer pool than the rule alone might suggest, since even a passive institutional investor may need to structure around it carefully. Get this answer from counsel in writing before any other planning starts, since it constrains every other choice that follows.

Criterion Two: How Concentrated Is Senior PE Ownership

If a small number of licensed principal engineers hold most of the equity and one is nearing retirement, a targeted internal buyback funded by the remaining licensed partners, run through Carta, usually satisfies both the ownership rule and the retiring partner's liquidity need without complication. A firm with a broader base of licensed staff holding smaller stakes has more flexibility in how it structures a program, since no single transaction risks pushing the firm's licensed-ownership percentage close to its floor.

Criterion Three: Does The Firm Need Outside Capital At All

Engineering consulting firms often carry lower capital needs than product companies, so ask honestly whether this is a liquidity problem or a growth-capital problem before assuming Forge's institutional network is the answer. If it is purely about giving a retiring principal cash, Carta funded from firm reserves is usually sufficient and avoids the licensure complexity of vetting an outside institutional buyer.

Criterion Four: How Would An Institutional Buyer Even Structure Around The Rule

If the firm does want outside capital, Forge-sourced buyers typically need to structure as a non-controlling, non-voting stake, or invest through a separate services entity that does not itself hold the engineering license, mirroring the same kind of structure other licensed professions use. Confirm this with the state licensing board's own guidance or outside counsel before assuming any institutional structure automatically works.

Putting The Criteria Together

Most engineering firms land on Carta for routine partner transitions, since the licensed-ownership constraint makes a narrow, internally vetted buyer pool the natural fit anyway. Forge becomes relevant only for a firm large enough, and structured carefully enough, to bring in non-voting institutional capital without threatening its licensed-ownership requirement, which is a smaller subset of firms than the platform's general marketing might suggest.

Before choosing a platform, run through these checks:

  • Get your state's professional engineering ownership rule, and how much non-licensed ownership it permits, confirmed in writing by counsel.
  • Check how concentrated senior licensed ownership is and whether the remaining licensed partners can fund a retiring principal's buyout.
  • Decide honestly whether the need is liquidity for a principal or growth capital before assuming an institutional network is the answer.
  • If outside capital is needed, confirm a non-voting or separate services entity structure with counsel or the state licensing board.
  • If the firm practices in several states, verify the ownership rule in each one rather than only the home state.

A Note On Multi-State Practices

A firm licensed and practicing across several states cannot assume one state's ownership rule governs the whole entity; some states apply the requirement at the entity level regardless of where a given project sits, while others look at where the work is actually performed. Pitfall: confirming compliance in the firm's home state and assuming that clears every state where it holds a license, when a multi-state practice often needs a state-by-state review before any ownership change.

What Retiring Principals Should Expect

A principal engineer planning retirement should expect the buyout conversation to start well before the actual transition, often two to three years out, since firms this size rarely keep enough idle cash to fund a large buyout on short notice. Raising the topic early gives the remaining partners time to build the necessary reserve or arrange financing, and it gives the retiring principal a realistic sense of the timeline rather than an expectation the firm cannot actually meet.

Building A Repeatable Transition Process

Firms that treat each partner transition as a one-off negotiation tend to see inconsistent terms and, eventually, hard feelings between partners who compare notes. Write down a standard methodology once, how the firm values a departing principal's stake, over what timeline it typically pays out, and how it screens any outside capital against the licensure rule, and apply it consistently. A documented, repeatable process also makes the eventual conversation with each new principal joining the firm easier, since they know from day one what to expect when their own transition eventually comes. Bring in outside counsel and a valuation professional the first time the firm runs this process, even if future transitions lean more heavily on internal templates once the methodology exists; the upfront cost of getting the first one right, both legally and in terms of the precedent it sets among partners, is small compared with the cost of unwinding a poorly structured arrangement a few years later.

Executive Capability Standard

What Good Looks Like

A licensed engineering firm manages this well when every partner transition happens without ever putting the firm's licensed-ownership compliance at risk.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Confirm your state's professional engineering ownership rule and how it applies to any proposed buyer before naming a platform.
2. Do Manually:Model a retiring principal's buyout against firm reserves and remaining partners' capacity to fund it.
3. Delegate:Give the firm's licensing compliance advisor sign-off authority on any transaction involving a non-licensed buyer.
4. Automate:Run internally funded, licensed-partner buyouts through Carta once eligibility and compliance are confirmed.
5. Buy:Bring in Forge's institutional network only for a carefully structured, non-voting investment vetted against the ownership rule in advance.

Frequently Asked Questions

Do all states require majority ownership by licensed engineers?

Most states have some version of this requirement for firms offering engineering services under their own name, but thresholds and permitted workarounds vary. Check your specific state board's rules rather than assuming a uniform national standard, since the exact ownership share and allowed structures differ.

Can a non-engineer ever hold equity in an engineering firm?

Often yes, up to whatever minority threshold the state permits, or through a separate services entity that does not itself hold the professional license, which is the structure most outside investors use to participate without violating ownership rules.

Why would a firm this small even need Forge's institutional network?

Most would not for a routine partner liquidity event; Forge becomes relevant mainly for a larger firm pursuing meaningful non-voting growth capital rather than for the typical case of one retiring principal wanting to cash out.
