Most first-time founders hiring a development agency skip writing anything close to a formal brief. They jump on a call, describe the idea conversationally, and ask for a quote. The result is usually three wildly different numbers from three agencies, each one scoping a slightly different, half-understood project, with no easy way to tell whether a lower quote means better value or just a smaller, less complete scope. A short, clear RFP fixes this, and it is far less work to write than most founders expect.
An RFP does not need to be a fifty-page procurement document. For a startup, it is closer to a well-organized one or two page brief that makes sure every agency you talk to is quoting on the same project, which is the entire point.
When an idea only exists as a conversation, every agency fills in the gaps differently based on their own assumptions and their own incentive to win the deal. A written RFP forces the founder to do the harder thinking upfront: what is actually required for a first version versus what would be nice eventually, what existing systems does this need to talk to, and what does success look like in three months. That clarity alone often surfaces scope questions a founder had not fully worked through, well before any code gets written.
It also changes the quality of the conversation with each agency. Instead of spending the first call re-explaining the basics, you spend it discussing how each agency would approach the problem, which is a far better signal of who you should hire than how polished their initial pitch deck is.
A two-person founding team building a marketplace app spent an afternoon writing a two-page brief: the core problem (connecting local service providers with customers), the must-have features for launch (listings, booking, and payments), explicitly excluded features for version one (in-app messaging and reviews, planned for later), target platforms (iOS and Android, not web at launch), and a rough budget range. They sent the same document to four agencies. Two of the four quotes came back close to each other and matched the founders' own rough budget expectations; one came in far higher, having assumed a much larger scope than intended, which was a useful, cheap signal of a mismatch caught before any contract was signed; and one raised a smart scoping question about the payment flow's regulatory requirements that the founders had not considered, which shaped their eventual decision more than the price did.
Once proposals come back, resist the temptation to sort purely by price. A simple scorecard, even a basic spreadsheet, forces a more honest comparison. Useful columns include: how closely the proposed scope matches your must-have list, whether the team has relevant experience in your specific type of product (a marketplace, a data-heavy dashboard, and a consumer social app all require different instincts), the clarity and specificity of their proposed timeline, how they answered your judgment-testing questions, and only then, total cost. A proposal that is meaningfully cheaper but vaguer on scope and timeline is not necessarily a better deal, since ambiguity in a proposal has a way of resurfacing as a change order once the project is underway.
It is also worth explicitly asking each agency how they handle scope changes once a project has started, since even a well-written RFP will not anticipate everything. An agency with a clear, fair change-request process is a better long-term partner than one whose proposal looks cheapest today but has no defined process for handling the inevitable adjustments a real project needs.
A good RFP does not end the scoping conversation, it starts it on a much stronger footing. Expect the chosen agency to run a more detailed discovery phase once selected, digging into exact user flows, data models, and edge cases that a brief-level document is not meant to capture. The RFP's job was to get you to a fair, comparable shortlist and a chosen partner quickly; the discovery phase's job is to turn that shared understanding into a buildable specification. Founders who treat the RFP as the entire scoping process, and skip a real discovery phase with their chosen agency, are the ones most likely to hit scope surprises three or four weeks into development.
If a blank page is the biggest obstacle, a simple structure works for most early-stage projects: a short paragraph on the problem and target users, a bulleted must-have feature list, a separate bulleted nice-to-have list explicitly marked as out of scope for version one, target platforms and any required integrations, a rough budget range and desired launch timeframe, and two or three specific questions you want every agency to answer in their response. That structure fits comfortably on one or two pages for most MVP-stage projects, and expanding it further is rarely necessary until a project is genuinely large or technically complex.
Founders often worry about sharing a product idea with multiple agencies before signing anything. A simple mutual non-disclosure agreement, sent alongside the RFP, addresses most of this concern and is standard practice that a legitimate agency will sign without objection. It is worth noting that most ideas are far less unique than founders assume, and the actual value in a startup is almost always in the execution and speed to market, not in the idea being kept secret from a handful of vetted development partners evaluating a brief. A short NDA is a reasonable, low-friction step; refusing to describe the project at all until a contract is signed tends to produce vague, unreliable quotes instead.
It is also reasonable to ask each agency about their own confidentiality practices, including how client information and code are handled internally and whether they work with any subcontractors who would also need to be covered under the agreement. A professional agency will have clear, ready answers to these questions, and their willingness to address them transparently during the RFP stage is itself a useful signal about how they will handle sensitive product details once a real engagement begins.
Writing a proper RFP takes a founder an afternoon, and it consistently saves far more time than that during vendor selection by making quotes genuinely comparable and surfacing scope problems before they become budget overruns. It is one of the highest-leverage documents a non-technical founder can produce before hiring outside help. You can review examples of completed projects in our project portfolio.
