Feature Comparison

Finsi OS

Profit Intelligence Engine

Move beyond basic revenue reporting to real-time, actionable profit analytics. This module delivers a daily-updated P&L and drills down into true unit economics and contribution margin by product, cohort, and channel. It surfaces exactly which segments are driving real profit versus just top-line sales, enabling hyper-informed decisions on budget allocation and product strategy without monthly spreadsheet nightmares.

AI-Powered Retention Autopilot

This is the heart of churn defense. Finsi's AI agents continuously analyze customer behavior patterns to predict churn risk and assign health scores. It then automatically orchestrates personalized retention campaigns across email and other channels, targeting at-risk customers with the right message at the right time. This hands-off approach turns customer success from a reactive firefight into a proactive, scalable system.

Creative Studio with AI Generation

Stop guessing what ad creative will work. This feature generates high-converting ad creatives using AI, leveraging over 35 proven hook-angle combinations tailored to your brand. It includes visual generation tools and even detects creative fatigue, alerting you when it's time to refresh assets. This turns creative production from a bottleneck into a scalable, data-informed process.

Smart Segmentation & Natural Language Queries

Ditch complex dropdown filters. Describe the customer segment you need in plain English—like "customers who bought in December but haven't opened an email in 30 days"—and Finsi's AI builds it instantly. These dynamic segments can be pushed in real-time to Klaviyo, Meta Ads, and other platforms for immediate campaign activation, closing the gap between insight and execution.

Size The Market

AI-Powered Market Surveillance

Forget manual checks and outdated data. Size The Market deploys advanced machine learning algorithms to provide 24/7 automated surveillance across a massive network of 1000+ e-commerce websites. It tracks the critical metrics that matter: real-time price changes, promotional campaigns, stock level fluctuations, and MAP violations with an industry-leading accuracy of 99%+. This continuous, intelligent monitoring ensures you have a live pulse on the entire market, not just fragmented snapshots.

Intelligent Product Matching Engine

Matching your SKUs to thousands of competitor listings is a monumental task—until now. Our core ML technology automatically and accurately matches your products with identical or comparable items across any monitored competitor catalog. This eliminates the guesswork and manual labor, providing a clean, reliable data foundation for all your analysis and ensuring you're comparing apples to apples in the global marketplace.

Real-Time Alert & Dashboard Command Center

Knowledge is power, but only if it's immediate. The platform features a sleek, customizable dashboard that visualizes complex market data into intuitive charts and graphs. More critically, it comes with a robust instant alert system. Get notified the moment a key competitor drops their price, runs a flash sale, or goes out of stock, allowing your team to react with strategic precision in real-time, turning market movements into your opportunities.

Advanced Analytical Calculators

Move from observation to optimization with built-in analytical tools. Size The Market includes specialized calculators designed for strategic decision-making.

Use Cases

Finsi OS

Automated Churn Prevention for Subscription Brands

For DTC subscription businesses, involuntary churn from payment failures is a silent revenue killer. Finsi OS integrates with platforms like Recharge and Chargebee to identify customers with expiring or failing cards. It automatically triggers personalized email sequences and recovery flows before the customer is lost, dramatically improving retention rates and protecting recurring revenue without manual intervention.

Profit-Driven Ad Spend Optimization

E-commerce brands waste ad budget on unprofitable channels. Finsi OS uses multi-touch attribution with customer quality scoring to show which Meta or Google Ads campaigns actually drive high-LTV, profitable customers, not just clicks. The Ads Autopilot module can then automatically pause underperformers and scale winning campaigns, ensuring every dollar spent maximizes return on ad spend (ROAS).

Scaling Personalized Customer Journeys

Manually building lifecycle emails for different customer segments is time-consuming. Finsi OS analyzes individual customer behavior and predictive LTV to automatically place them in hyper-targeted journey tracks. Its Email Intelligence module then helps plan and generate personalized campaign content, ensuring high-value customers receive VIP treatment while re-engagement campaigns target at-risk segments.

Unifying Cross-Platform Data for Strategic Decisions

Founders and operators spend hours pulling data from Shopify, Klaviyo, and ad platforms into spreadsheets. Finsi OS connects all these sources in minutes, providing a unified dashboard with correlated insights. This reveals how support ticket trends impact churn or how specific products affect LTV, turning fragmented data points into a clear strategic narrative for leadership.

Size The Market

Dynamic Pricing Strategy Execution

E-commerce teams use Size The Market to fuel their dynamic pricing engines.

The platform provides the live market feed needed to make pricing algorithms truly reactive, ensuring you're always positioned perfectly without manual intervention.

Brand Equity and MAP Compliance Monitoring

For manufacturers and premium brands, protecting Minimum Advertised Price (MAP) policies is non-negotiable. Size The Market automates the tedious process of scanning hundreds of retailer sites for violations. It instantly flags any seller undercutting agreed-upon prices, enabling brand managers to take swift action to enforce policies, maintain brand value, and ensure fair competition across all sales channels.

Competitive Launch and Promotion Intelligence

When launching a new product or planning a major sales campaign, you need to know the landscape. Agencies and brand strategists use the platform to analyze competitor promotions, stock levels, and pricing trends in specific categories. This intelligence allows them to time their launches perfectly, structure promotions for maximum impact, and avoid launching into a crowded or discounted market.

Market Share Expansion and Assortment Planning

Retailers looking to expand into new categories or regions leverage Size The Market's tracking and analytics. They can size up new markets, identify top-selling products and pricing trends, and discover gaps in competitor assortments. This data-driven insight informs inventory purchasing, category strategy, and pricing models to capture market share aggressively and with confidence.
