About Us
Built on 20 Years of Enterprise Fintech Expertise -Now Delivering AI-First Solutions
Gatitaa Techub Inc. brings two decades of large-scale payments and fintech engineering to the banks, credit unions, and payment companies now racing to adopt AI safely. We’ve built and run the kind of mission-critical systems these institutions depend on — and we help them modernize with AI that meets the same bar for compliance, security, and reliability.
Two decades inside enterprise fintech — now focused on AI
Our leadership was forged inside one of the world’s largest payments companies, leading enterprise online and walk-in bill-payment platforms — an 80+ person engineering organization across the U.S. and India, and 40+ mission-critical production applications processing real payments under real regulatory scrutiny.
That experience shapes everything we build. AI in a regulated environment isn’t a demo — it’s production software that has to be auditable, secure, and human-supervised. We bring the discipline of enterprise fintech to every AI system we deliver.
Why it matters for you
Most banks and fintechs know AI can transform their document-heavy workflows — check processing, KYC/KYB, receivables, reconciliation — but don’t want to build an internal AI team to get there. Gatitaa closes that gap: enterprise-grade delivery, without the enterprise-sized team on your side.
Our solutions use technologies such as Amazon Textract, Amazon Bedrock, OCR, and intelligent document processing to extract and validate information from checks, bank statements, identification documents, applications, invoices, and onboarding forms.
We build secure AI agents, automate KYC/KYB and customer onboarding, streamline check and payment exception processing, modernize legacy payment platforms, and implement AWS-native AI solutions. Common use cases include:
- Check scanning and data extraction
- Check-image classification and validation
- Signature and field detection
- Payment exception investigation
- KYC/KYB document processing
- Identity-document data extraction
- Customer and merchant onboarding
- Bank-statement and application processing
- Fraud-review assistance
- Operations knowledge assistants
- Reconciliation and compliance workflows
- Human-in-the-loop document verification
Every engagement is designed around security, privacy, human oversight and auditability. We help customers move beyond isolated proofs of concept and deliver measurable improvements in processing time, accuracy, operational cost and customer experience.
