Equity-for-Build Deals: When to Say Yes, When to Walk, and How to Structure the Cap Table

Every agency with a decent portfolio gets the email. A founder with an interesting deck, no revenue, and a proposal that goes something like: "We can't afford your rate, but we'll give you 10% of the company to build the MVP." Some of these deals turn into the best returns your studio will ever see. Most of them turn into six months of unbilled hours and a cap table screenshot you'll show at parties.

After running enough of these — some that worked, several that didn't — here's the framework we use before we sign anything.

Why equity-for-build looks tempting (and usually isn't)

On paper, the math is seductive. You'd bill $200k for the build. They offer you $200k worth of equity at a $2M post-money valuation. That's 10%. If the company hits a $50M exit, you clear $5M. Beats the invoice.

The problem is that this math assumes three things that are almost never true at signing:

• The valuation is real (it isn't — it's a number the founder made up).
• Your equity won't get diluted into oblivion (it will).
• The company will actually exit (roughly 1 in 10 seed-stage startups return meaningful capital, and that's being generous).

So the honest expected value of a $200k equity package at pre-seed is nowhere near $200k. Depending on who you ask, it's somewhere between $10k and $40k in risk-adjusted terms. If you'd take a $30k invoice for a $200k build, sure, sign up. Nobody would.

That doesn't mean equity deals are always bad. It means the deal has to be structured so you're compensated for the risk, not just the notional value.

The three tests before you even open the term sheet

Before we talk numbers, we run any inbound equity offer through three filters. If it fails any of them, we pass.

1. Is there a real founder with real skin in the game?

A technical co-founder who quit their job counts. Two marketers who have a Notion doc and a domain name do not. If the founding team hasn't put personal capital, career risk, or a specific unpaid year into the business, they're asking you to take more risk than they are. That inverts the incentive: they'll pivot the idea five times while you eat the build cost each time.

2. Is there a wedge, or is this a platform?

Equity deals work when the MVP is scoped, small, and testable. "Build us the marketplace, the mobile app, the admin panel, and the AI matching engine" is not an MVP — it's a two-year commitment disguised as a sprint. If you can't ship the first useful version in 8–12 weeks of focused work, the deal will drag, the founder will run out of runway, and your equity will vest in a corpse.

3. Would you invest cash at this valuation?

This is the killer question. If a founder is offering 5% for a $150k build, they're saying the company is worth $3M. Would you write a $150k check at a $3M valuation for this team, this idea, this market? If the answer is no, then taking equity instead of cash is worse — you're doing the same investment plus you're eating opportunity cost on your team's time.

Structuring the deal so it doesn't eat you alive

Assume the project passes all three tests. Now the structure matters more than the percentage. We've seen agencies hold "15% of a unicorn" that turned out to be 0.4% after four rounds because the paperwork was sloppy.

Never do pure equity. Do hybrid.

Our default is a 40/60 or 50/50 split: half the fee in cash (often deferred, paid on close of next round), half in equity. This does two things. It forces the founder to actually raise or generate revenue — a real deadline — and it keeps your studio's cash flow alive.

A rough term structure we've used:

Project fee:        $240,000 (market rate)
Cash portion:       $120,000
  - $40k on signing
  - $40k at milestone 2
  - $40k on close of next priced round (or 12 months, whichever first)

Equity portion:     $120,000 notional
  - Issued as founder-preferred or SAFE with MFN
  - Valuation cap = current round cap, or $X if pre-money
  - Anti-dilution: broad-based weighted average
  - Vesting: none (already earned on delivery) OR
              12-month cliff tied to delivery milestones

Take the equity as a SAFE, not common stock

Common stock for services gets you taxed on receipt at whatever the 409A says the shares are worth, and it sits at the bottom of the liquidation stack. A SAFE with a valuation cap converts alongside the next round's investors, gives you preference in a liquidation, and doesn't trigger a taxable event until conversion. If the founder pushes back, they're either badly advised or hoping you don't know the difference.

Get the anti-dilution clause in writing

Without it, your 5% becomes 3% after seed, 1.8% after Series A, and a rounding error by Series B. Broad-based weighted average is standard for investors — ask for the same. You won't always get it, but you should always ask.

Cap your exposure

Write a hard ceiling into the SOW. Something like: "Agency will provide up to 800 hours toward MVP delivery. Additional scope beyond 800 hours will be billed at $X/hour cash, or negotiated as additional equity at the then-current valuation." Without this, you will do 1,400 hours. We promise.

The IP question everyone forgets

Here's the one that ends friendships. Who owns the code before the equity vests? Before the SAFE converts? If the founder ghosts you at month four with a working MVP and no signed conversion, do you own the repo or do they?

Our standard: IP transfers on cash payment milestones, not on equity issuance. If the cash portion isn't paid, we retain a perpetual license to reuse the codebase (minus their trademarks and business logic). This is not adversarial — it's the same protection any lender takes. Founders who fight this are telling you something.

When to walk, even from a great-looking deal

Walk if:

• The founder wants you to defer 100% of fees for equity. They're broke, not strategic.
• They can't articulate the next 12 months of milestones, hires, and fundraising plan.
• They've already done this dance with another agency. Ask. It's a red flag if a previous shop bailed.
• The equity offer is contingent on "performance" defined by them, not by shipped milestones.
• Your team isn't excited about the product. Equity work with a demoralised team ships slowly and badly, which kills the equity value directly.

What a good outcome actually looks like

The equity deals that have paid off for studios we know share a pattern: small initial scope, hybrid cash-plus-SAFE, founders who raised a seed round within nine months of MVP launch, and a follow-on paid retainer once the round closed. The equity was a kicker, not the point. The cash covered the build. The relationship converted into a normal client with an option upside.

The deals that failed had one thing in common: the agency treated the equity as the primary compensation and the project as a side bet. Every time the founder asked for "one more thing," the team said yes because they were emotionally invested in the outcome. That's not a partnership — that's an unpaid co-founder role with worse governance.

Where we'd start

If you're an agency getting your first equity pitch this quarter: don't say yes in the meeting. Ask for the deck, the cap table, the current bank balance, and the last three months of runway. If they can't send all four within a week, the answer is no. If they can, run the three-filter test above, then send back a hybrid term sheet with a SAFE, a cash floor, and a scope cap.

And get a lawyer to paper it. A $2k legal bill on a $200k deal is not the place to save money. If you want to talk through how we structure these on the delivery side, our product engineering services page outlines how we scope MVPs in a way that survives equity terms — and our blog has more on the agency-to-product transition if that's where this deal is quietly pointing you.
