How to Write a Proposal for Fintech Clients: The Agency Playbook

Fintech companies are fast-moving, technically sharp, and operating in a heavily regulated environment. A generic agency proposal won't survive first contact. Here's how to build one that does.

How Fintech Teams Evaluate Agencies

Fintech is a broad label covering an increasingly diverse range of companies: B2C challenger banks and payment apps, B2B banking infrastructure and embedded finance, lending and credit platforms, wealth management and investment tools, insurtech, and crypto/Web3 products. Each sub-vertical has different marketing dynamics, different regulatory environments, and different buyer psychology.

What unifies them: fintech buyers are analytically rigorous and have very low tolerance for agencies that don't understand their industry. The marketing team at a growth-stage neobank will likely have ex-consultants, ex-banking professionals, and data scientists on it. An agency proposal that reads as a reheated B2B SaaS pitch with “fintech” dropped in will be identified immediately.

What Fintech Buyers Are Evaluating

  • Do they understand financial services regulation well enough not to create compliance problems?
  • Can their team produce technically accurate content about complex financial products?
  • Are they comfortable with our pace — rapid sprints, A/B testing, data-driven decisions?
  • Do they know what metrics matter in our specific fintech model?
  • Have they worked with financial services or fintech companies before — or are we going to be their education?

It's also worth acknowledging the trust gap that fintech marketing faces with consumers. Financial products carry significant scepticism — people worry about scams, hidden fees, and data security. Your proposal should address how you will build credibility and trust in the brand's marketing, not just generate traffic or trial sign-ups.

Navigating Regulatory Sensitivity

Financial services marketing is one of the most regulated advertising categories globally. Non-compliance doesn't just create legal risk — it can result in advertising bans, forced campaign withdrawals, and regulatory sanctions. Your proposal must demonstrate you understand the regulatory landscape relevant to your client.

Key Regulatory Frameworks by Region

UK — FCA (Financial Conduct Authority)

Financial promotions must be approved by an FCA-authorised firm. Rules cover fair, clear, not misleading communications; required risk warnings (“Your capital is at risk”); restricted testimonials for investment products; and specific rules for cryptoassets under the FCA's crypto marketing regime (2023 onwards).

US — SEC, FINRA, CFPB, FTC

Investment products: SEC/FINRA rules on advertising — no hypothetical performance without extensive disclosures; testimonial rules post-2021 Marketing Rule; anti-cherry-picking for performance data. Consumer lending: CFPB and FTC rules on APR disclosures, unfair/deceptive practices. General: FTC advertising rules apply to all financial advertising.

EU — ESMA, PSD2, MiCA

Markets in Crypto-Assets (MiCA) regulation governs crypto marketing from 2024 onwards. Payment services under PSD2 have specific marketing transparency requirements. GDPR applies to all data collection and use in marketing.

In your proposal, include a section on your compliance review process for financial promotions. How will you ensure copy clears regulatory requirements before it goes live? Who reviews it — an internal legal resource, the client's compliance team, or a third-party financial promotions approval service? Fintech buyers are reassured by structured compliance processes, not by promises to “check the legal boxes.”

⚠️ Crypto and Web3 Fintech: If you are pitching a crypto or Web3 company, be especially aware of rapidly evolving ad platform policies. Meta, Google, and Twitter/X all have restricted or limited crypto advertising that requires pre-approval and certification. The UK FCA's crypto marketing rules (in effect since October 2023) are among the strictest globally. Know the rules before you pitch.

Establishing Technical Credibility

Fintech companies build complex products. Their teams are often highly technical — engineers, data scientists, and product managers who care about accuracy. When an agency produces content that misrepresents how their product works, or uses imprecise terminology about their technology, it damages credibility internally and externally.

Establish technical credibility in your proposal by:

Using accurate terminology
Know the difference between open banking and banking-as-a-service. Understand what "embedded finance" means in context. Reference specific technologies (APIs, ISO 20022, instant payment rails like FedNow or SEPA Instant) where relevant.
Showing fintech content samples
Include content samples — blog posts, landing pages, thought leadership — written for fintech or financial services clients. The quality and accuracy of these samples are evaluated closely by fintech marketing teams.
Naming your content process
Explain who writes your fintech content. Do you have writers with financial services backgrounds? Do you use subject matter expert interviews? Does your client's compliance team have a formal sign-off role in your process?
Referencing fintech-specific platforms
Show familiarity with tools common in fintech marketing — Braze or Iterable for lifecycle marketing, Amplitude for product analytics, Branch for mobile attribution, Heap for behavioural analysis.

Growth Metrics Fintech Clients Prioritise

Fintech growth metrics vary significantly by business model. Use the right ones for the specific type of fintech you are pitching:

Consumer Fintech (Neobanks, Payment Apps)
MAU/DAU, activation rate (first transaction within 7/30 days), funding rate (% who add money), account upgrade rate, ARPU, referral rate, churn rate
Wealth Management / Investment Platforms
AUM (Assets Under Management), investor acquisition cost, funded account rate, average portfolio size, engagement with investment content, NPS
Lending / Credit Platforms
Loan origination volume, cost per funded loan, default rate (context for targeting quality), average loan size, repeat borrower rate
B2B Fintech / Payments Infrastructure
ARR, pipeline velocity, deal size, MQL-to-SQL conversion, time-to-close, GMV (Gross Merchandise Volume) processed for payment platforms
Insurtech
Policy bind rate, cost per policy, renewal rate, loss ratio context (affects how you position the product), referral rate

In your proposal, identify which two or three metrics will be the north-star measures for success. Show how each element of your programme connects to moving those metrics. Fintech teams are used to measuring everything — they will appreciate the rigour, and they will notice if you avoid specifying how success will be measured.

Working with Fast-Moving Fintech Teams

Consumer fintech companies — especially growth-stage and VC-backed ones — operate at high velocity. Weekly sprints, rapid A/B testing, daily metric reviews. An agency that needs two-week turnaround on a landing page or three rounds of internal review before sending a brief will create friction fast.

Demonstrate in your proposal that you can match their pace:

  • Sprint-based delivery: Propose working in 2-week sprints with weekly check-ins. Show your deliverable cadence aligned to their team's working rhythm.
  • Shared project management: Propose using Linear, Notion, or the client's existing tool — not your own proprietary system. Fintech teams do not want to manage two project management systems.
  • Async-first communication: Many fintech teams are remote-first and rely on async communication. Propose a Slack channel or equivalent for fast iteration rather than scheduled email chains.
  • Rapid testing protocols: Show you have a framework for A/B testing ad copy, landing pages, and email subject lines at speed — not a 6-week testing cycle.
  • Named, accessible account team: Fintech buyers are tired of “senior person sells, junior person delivers.” Name your account team in the proposal. Show who is doing the work, not just who is presenting.

Note: enterprise fintech (B2B banking infrastructure, large financial institutions) moves differently. Here, pace is slower, approval cycles are longer, and the premium is on thoroughness and stakeholder management. Your proposal tone should adjust accordingly — show stability and process rigour for enterprise, agility and speed for growth-stage consumer fintech.

Proposal Structure for Fintech Clients

01
Understanding of Their Business Model
Show you understand which fintech sub-vertical they are in, what their product does, and what stage of growth they are at (pre-PMF, growth, scale). Reference their specific competitive landscape.
02
Regulatory Compliance Framework
A dedicated section on how you handle financial promotions compliance. Name the regulatory bodies relevant to their jurisdiction. Explain your review process.
03
Growth Strategy
Channel strategy tied to their specific growth model and stage. For consumer fintech: acquisition, activation, referral. For B2B fintech: demand gen, content, ABM. For lending: CPL-based acquisition.
04
Metrics and Success Criteria
Two or three north-star metrics, a dashboard view, and a weekly/monthly reporting cadence. Define how attribution will work, including for performance marketing.
05
Technical and Content Credibility
Content samples, your content production and accuracy process, and your experience with their relevant marketing tech stack.
06
Delivery Model
Sprint cadence, team structure (named contacts), communication protocols, and approval workflow. Show you can move fast without cutting corners.
07
Investment
Fee structured to reflect the compliance overhead and content quality requirements of financial services work. Include a risk-mitigation framing: the cost of a non-compliant campaign dwarfs the agency fee.

Red Flags That Kill Fintech Proposals

No mention of financial regulations
Sending a fintech proposal without acknowledging FCA, SEC, or relevant regulatory constraints signals fundamental inexperience with the sector.
Using incorrect or imprecise financial terminology
Confusing terms (calling a payment processor a "neobank," misrepresenting how open banking works) will be caught immediately by technically literate fintech teams.
Generic "financial services" experience as a substitute for fintech experience
A bank branch redesign from 2018 is not relevant to a Series B neobank in 2026. Be specific about which type of fintech you've worked with.
Slow delivery models
Proposing monthly check-ins and 3-week turnaround times to a growth-stage fintech that measures in weekly sprints is a structural mismatch.
Over-promising on ad performance
Financial services CPAs are typically high. Consumer fintech acquisition can cost $50–$300 per funded account depending on product. Set realistic benchmarks — don't promise CPAs that aren't achievable in the sector.
Ignoring trust as a product concern
Fintech brands are in the trust business. Marketing that is overly promotional or that downplays risk will create regulatory and reputational problems. Show you understand that trust-building is a core marketing objective, not a soft afterthought.

Frequently Asked Questions

What do fintech clients look for in a marketing agency proposal?

Fintech companies want agencies that understand their regulatory environment, speak the right growth metrics language, and can move at startup speed without cutting corners on compliance. They quickly identify proposals that lack genuine industry knowledge — specificity and technical credibility are essential.

What regulatory considerations affect fintech marketing proposals?

In the UK, FCA rules cover fair financial promotions, required risk warnings, and crypto advertising. In the US, SEC/FINRA, CFPB, and FTC rules govern investment, lending, and consumer financial marketing. Your proposal should acknowledge the relevant regulatory framework and describe your compliance review process for all financial marketing assets.

What growth metrics do fintech companies use?

Consumer fintech: MAU/DAU, activation rate, funding rate, ARPU. Wealth management: AUM, investor acquisition cost, funded account rate. Lending: origination volume, cost per funded loan. B2B fintech: ARR, pipeline velocity, GMV. Match your metrics language to the specific fintech sub-vertical.

How do I demonstrate technical credibility in a fintech proposal?

Use accurate financial services terminology, reference relevant regulations correctly, show fintech content samples, explain your content production and accuracy process, and name your team's experience with fintech-specific marketing platforms like Braze, Iterable, or Amplitude.

How fast do fintech clients expect agencies to move?

Growth-stage consumer fintech moves at sprint pace — weekly check-ins, rapid A/B testing, fast turnaround. Enterprise financial services moves slower. Match your proposed delivery cadence to the client's operational speed, and be explicit about sprint structure and communication protocols.
