Somewhere around the time a founder finishes the prototype and starts pricing ad campaigns, the emails begin. Agencies that specialize in crowdfunding will offer to run the launch, and the pitch is compelling: they have done this many times, they have audience data, they will work for a share of what they raise. Some of these firms are genuinely good and earn their fee several times over. Others are selling ad management with a percentage attached, and a few are selling nothing at all.
The difficulty is that the good ones and the bad ones make nearly identical claims. Here is what these agencies actually do, how the money is structured, and how to tell them apart before you sign.
What a crowdfunding agency really does
Strip away the language and the work falls into five buckets:
- Paid acquisition. The core service: building, testing and scaling ad campaigns optimized toward pledges rather than clicks. Most of the budget and most of the value sits here.
- Pre-launch list building. Driving traffic to a landing page or follow button, then warming that list until launch.
- Launch-day sequencing. Coordinating email, ads and outreach so pledges concentrate in the first hours, which platform ranking and press both respond to.
- Creative and page optimization. Ad variants, sometimes page copy, occasionally video edits. Fewer agencies produce the main video than claim to.
- Press and creator outreach. The least reliable service. Real relationships exist at some firms; at others this means a mass email to a purchased list.
What they generally do not do: fix a product nobody wants, invent demand in a category with no audience, or rescue a campaign whose cost model was broken before launch. Advertising amplifies conversion; it does not create it.
How the money is structured
| Model | How it works | Watch for |
|---|---|---|
| Percentage of pledges | Agency takes a share of funds raised, often in the low double digits | Whether the percentage applies to all pledges or only attributed ones |
| Monthly retainer | Fixed fee for a defined scope over the campaign period | Scope creep and what happens if you extend |
| Ad management fee | Percentage of ad spend, commonly 10–20 percent | Incentive to spend more, not to spend well |
| Hybrid | Smaller retainer plus a performance share | Usually the fairest structure; check both halves |
| Pure performance | Agency funds the ads and takes a large share of the raise | Rare, high percentages, and they will only take campaigns already likely to succeed |
The critical question in any percentage deal is attribution. A share of pledges the agency actually generated is a fair deal. A share of every pledge, including the backers you spent a year assembling on your own email list, is not — and that clause has quietly cost founders large sums. Insist that the fee applies to tracked, attributed pledges, and agree in advance on the attribution window and the tool that measures it.
The second question is who pays for media. In most arrangements you do, on top of the fee. Ad spend can match or exceed the agency fee, and it comes out of money you have not received — platforms disburse after the campaign closes, while ad bills arrive weekly. Founders have had to stop scaling a working campaign for lack of cash on hand. Budget the float. The wider picture is in a realistic marketing budget for a new product.
Does the math work
Run the arithmetic before you take any meeting. If your product's contribution margin after manufacturing, packaging, freight, fulfillment, platform fees and payment processing is thin — which it usually is at campaign volumes — an agency fee plus ad spend can push attributed pledges to negative margin. You raised more and kept less.
Do this calculation per pledge, not on totals:
- Start with the pledge price of your main tier.
- Subtract platform and payment fees.
- Subtract landed unit cost, packaging and outbound shipping.
- Subtract the agency percentage.
- Subtract the media cost per acquired backer, which is the number the agency should be able to estimate from comparable campaigns.
If the remainder is not comfortably positive, the agency cannot help you — the problem is pricing or cost, and it has to be fixed upstream. Comparing this against the all-in campaign budget in what a Kickstarter campaign costs to run keeps the numbers honest.
How to evaluate a firm
Ask for specifics and watch how they answer:
- Campaigns in your category. A firm that launches consumer gadgets may know nothing about a professional tool or a medical accessory.
- References you choose. Get a full list of campaigns, then contact founders you pick rather than the ones they nominate. Ask what the agency did versus what the founder did.
- Attribution methodology. A serious firm explains tracking clearly. Vagueness here is the strongest warning sign.
- Who does the work. The person selling is rarely the person running the account. Ask to meet the media buyer.
- Failed campaigns. Everyone has them. A firm claiming none is new or not telling the truth.
- Pre-launch requirement. Good agencies start months ahead and decline campaigns that arrive a week out.
Red flags: a guaranteed funding amount, pressure to sign within days, refusal to run a small paid test before committing, ownership of your ad account or pixel data, an all-inclusive fee that also covers press with no named contacts, and an unwillingness to work alongside your own list. Any firm that wants your platform account credentials rather than delegated access should be declined outright.
Contract terms that matter
- Fee base defined precisely — attributed pledges only, with the attribution window stated.
- Ad accounts, pixels, creative files and audience data owned by you and transferable at the end.
- A spend cap you control, with written approval required to exceed it.
- Termination rights mid-campaign, with fees prorated.
- Reporting cadence and the metrics reported: cost per pledge, not impressions.
- No claim on post-campaign sales unless you specifically hire them for that phase.
- Confidentiality covering your customer list, which is an asset you keep.
When to hire one, and when not to
Hiring makes sense when the product is finished and manufacturable, the margin supports the fee, the goal is large enough that professional media buying beats amateur work, and you are launching into a category where paid acquisition actually converts — visual, consumer-facing, impulse-priced products above all.
Skip the agency when the margin is thin, when the audience is a narrow professional niche better reached through trade channels than social ads, when your goal is small enough that the fee dwarfs the incremental raise, or when you have not yet built any list of your own. In that last case the money is better spent earlier, on building an email list before launch and on a video that actually converts, both of which raise the return on every dollar spent later.
The middle path
Many founders get most of the benefit for a fraction of the cost by unbundling. Hire a freelance media buyer on a modest retainer. Buy the video from a production house that does product work. Handle press and community yourself, since founder outreach outperforms agency outreach in most niches. This takes more coordination, but you keep the audience data and the percentage.
Whichever route you choose, the leverage sits earlier than the ad account. A campaign built on a product that is genuinely ready, priced with a real cost model and aimed at a defined audience is one that marketing can amplify — the sequence described in launching a product through crowdfunding.
Projects House works on the part no agency can supply: a product engineered, manufacturable and costed well enough that paid acquisition returns more than it consumes. If you want the engineering and cost side solid before committing to marketing spend, reach us through our contact form.
