Can Teamextn deliver? Let's see…

Streetteam

Client: US-based Digital Collectibles & Fan Engagement Platform

Challenge

The customer inherited a mature, eight-year-old product that was feature-rich but hard to maintain, with degraded performance and a UX misaligned with the product vision. They needed to launch an MVP quickly to validate the market and support fundraising—without the time and cost of a full rebuild.

Our Approach

We worked with the founders to identify the core MVP and simplify the product around what mattered most. Instead of a complete rewrite, we modernized the existing application incrementally—improving performance, refining workflows, and enhancing UX while reusing proven parts of the platform. This reduced risk, accelerated delivery, and preserved years of business logic.

Business Outcomes

  • Delivered a production-ready MVP in ~5 months
  • Improved performance and user experience
  • Reduced technical complexity while preserving business value
  • Created a maintainable platform for future development
  • Freed founders to focus on customer validation and seed fundraising

Toll-Free Routing Platform

Client: US Voice & Data Telecommunications Carrier

Challenge

The customer needed a high-performance routing platform for large-volume toll-free call lookups with strict latency requirements, integrated with existing telecom infrastructure, and supporting configurable routing rules, carrier overrides, and future scalability.

Our Approach

We built a scalable architecture around the customer's existing ecosystem instead of replacing it — implementing the core routing engine, configurable business rules, and high-performance APIs so the platform could grow with the business while their engineering team took ownership over time.

Business Outcomes

  • 600M+ API requests processed monthly
  • Architecture built to scale to 2B+ monthly requests
  • High-performance API powering mission-critical routing
  • Seamless integration with existing infrastructure

AI-Powered Merchandising Platform

Client: Large US Online Grocery Retailer

Challenge

Merchandising and advertiser operations teams relied on manual workflows to coordinate vendor campaigns, approvals, and reporting—an effort-intensive process that made timely, revenue-maximizing insights difficult to generate. The customer wanted to use Generative AI to automate repetitive workflows, improve team collaboration, and enable faster, data-driven decisions.

Our Approach

We partnered with the product owner and business stakeholders to understand existing workflows before identifying where AI could deliver meaningful value—rather than adding AI for its own sake.

We designed AI-assisted workflows that automated repetitive tasks, generated contextual insights, and streamlined cross-team collaboration, backed by intuitive interfaces with workflow visibility, audit capabilities, and an AI-powered assistant to explain recommendations and impact. The platform was built to handle large, multi-dimensional datasets while scaling with future requirements.

Business Outcomes

  • Reduced manual effort across merchandising and advertiser operations
  • Accelerated access to actionable business insights
  • Improved collaboration through AI-assisted workflow automation
  • Enabled faster, data-driven decisions to maximize vendor revenue
  • Built a scalable platform for future AI-powered automation

What our clients say.

StreetTeam

Working with TeamExtn has been a genuinely great experience. The team consistently delivers high-quality work on time, communicates proactively, and brings real professionalism to every stage of the project. What stands out most is how much they feel like an extension of our own team — reliable, skilled, and easy to work with. Recommended without hesitation. The best part, any idea I have instantly becomes better once I share with them. The vision I have in mind and the end-product are night & day different - but in the best possible way!

Unseen

Gaurav and the team at Teamextn were instrumental in helping us build out a high-quality MVP for Unseen. The team was forthright in their cost estimates and over delivered on their promises time and time again, whether it was guaranteeing a certain feature build out or even helping us build materials for investors / presentations to demo. I'm extremely happy with the end result and jumpstart that Teamextn gave us on our MVP, especially given our lean budget.

Awesome People Leaders

We really appreciated working with the Teamextn team. They were very responsive to any of our questions, needs, and iterations of the work. Throughout the process, they added value by asking insightful questions that pushed us to think about aspects of our project we had not considered and produced a better outcome as a result. We would work with Teamextn again and highly recommend them!

OpenDirector

If it weren’t for Gaurav, I wouldn’t be working with a team in India. Gaurav possesses rare and exceptional skills in software architecture, coding, project management, team building, and delivering high-quality work. Thanks to his involvement in the project, I am able to concentrate on other crucial aspects of my business. I highly recommend working with Gaurav.
