Most fintechs don't know their end-to-end payment performance until a merchant complains. By then the conversation is already about churn, not optimisation. The Merchant Conversation You Don't Want to

Hi Hashnode Community,
As technology demands our attention, and agility requires us to change we continue to keep up, learn and do more in various capabilities.
But here’s a question:
What if you could reduce costs by up to 30%, double your speed to market, and deliver customer-centric solutions—without burning through your budget?
In today’s high-stakes fintech world, speed, innovation, and cost-efficiency are the keys to survival and success. Here’s the reality:
The fintech market is projected to skyrocket from $294.74 billion in 2023 to $1.15 trillion by 2032, growing at an impressive 16.5% CAGR (Fortune Business Insights).
But despite this massive opportunity, many fintechs bleed cash unnecessarily. Bloated infrastructures, over-engineered products, and poorly optimised resources can kill momentum and drain even the most promising startups.
The lean startup approach is a game-changer. It combines:
✅ Rapid iteration with MVPs
✅ Data-driven decision-making
✅ Optimised cloud strategies
✅ Automation for efficiency
The result? Fintechs that thrive under uncertainty, innovate faster, and deliver exceptional value.
In this post, I’ll show you how to harness AWS tools like Amazon Cognito for identity verification and Fraud Detector for risk management—to streamline operations, cut costs, and scale smarter.
Let’s dive into actionable steps, real-world examples, and strategies you can implement right away.
1. Build-Measure-Learn: The Cost-Slaying Loop 🛠️
Fact: 90% of startups fail. Why? They build products nobody wants.
The Build-Measure-Learn cycle ensures you validate ideas quickly, fail fast (if needed), and iterate toward success:
Example: Launch a simple payment app that sends and receives money. No analytics, no social integrations—just solve the core problem.
• 📈 User Acquisition Rate
• 💡 Customer Retention (30-day rate)
• 😍 NPS (Net Promoter Score)
Proven Impact
Startups using MVPs save 60% on development costs compared to building full-featured products upfront.
Case Study: Dropbox ($8.9B valuation) began with a simple concept demo. Early adopters loved it, fuelling rapid growth.
Actionable Steps:
Use tools like Google Analytics to measure success.
Run A/B tests to refine features before scaling.
Cloud isn’t just a trend—it’s a cost-saving revolution.
Fact: Fintechs using cloud solutions can slash IT infrastructure costs by 35%.
Case Study: Monzo, the UK-based neobank, scaled to 6 million customers using AWS while avoiding the costs of on-premises data centers.
Actionable Tips:
1. Go Serverless: Use AWS Lambda or Azure Functions to run code only when needed.
• No idle servers. No wasted costs.
2. Optimize Usage:
• Monitor spend with AWS Cost Explorer.
• Automate scaling with tools like Auto Scaling and Compute Optimizer.
3. Adopt Multi-Cloud Strategies: Use AWS for storage and Google Cloud for ML to optimise performance and costs.
Data is the Fuel: Make Decisions That Matter 📊
In fintech, data drives growth. Every second, 1.7 MB of data is created per person but are you leveraging it?
Thrilling Stats:
Data-driven companies are 23x more likely to acquire customers and 19x more likely to be profitable (McKinsey Global Institute).
Predictive analytics can increase ROI by 10-15%.
Actionable Steps:
Use Snowflake or BigQuery to consolidate customer data.
• Use Amazon SageMaker or DataRobot to predict customer behaviour.
• Test features and campaigns to see what resonates.
• Example: Chime, a digital bank, improved onboarding by 18% through experiments.
Reality Check: 64% of product features are rarely or never used.
• Case Study: Robinhood scaled to a $20B valuation by focusing on one core feature: commission-free trading.
Action Steps:
1. Audit Your Features:
• Use analytics to identify unused features. Remove or deprioritise them.
2. Focus on Customer Problems:
• Conduct interviews and surveys to uncover pain points.
3. Partner for Value:
• Use third-party APIs like Plaid (account linking) or Stripe (payments) instead of building in-house.
Automation isn’t just a convenience—it’s your secret weapon for slashing costs and boosting efficiency.
Stat: Fintechs report up to 40% cost reductions in compliance, onboarding, and customer service through automation.
AWS Tools for Financial Crime and Identity Verification:
Amazon Cognito: Secure user authentication and multi-factor verification.
Amazon Rekognition: Verify identities using facial recognition.
Amazon Fraud Detector: Detect anomalies and suspicious activity with ML.
AWS Lambda: Automate workflows like fraud alerts and risk flagging.
Use Case: Build a robust AML/KYC pipeline to meet fintech security and compliance needs.
• Benefits:
• Save 50% in development costs.
• Reduce time-to-market by 60%.
Action Steps:
1. Integrate with APIs:
• Use Plaid for financial data.
• Use Twilio for communication.
2. Partner for Growth: Collaborate with fintech ecosystems to co-create solutions.
3. Monetise APIs: Offer your APIs as a new revenue stream.
Cost optimisation isn’t a one-time activity—it’s a habit.
Fact: Up to 70% of cloud costs are wasted due to inefficiencies.
Action Steps:
1. Conduct Quarterly Cost Audits:
• Use AWS Cost Explorer and Compute Optimiser to find unused resources.
2. Renegotiate Vendor Contracts: Get the best rates from cloud providers.
3. Implement FinOps: Align cloud spend with business goals using cross-functional teams.
In the thrilling world of fintech, innovation doesn’t have to cost a fortune. Staying lean, agile, and customer-focused is the recipe for success.
The lean startup approach—paired with tools like AWS, data-driven insights, and automation - will empower your fintech to:
✅ Reduce costs
✅ Move faster
✅ Deliver more value
