An alternative to traditional consumer lending

Acima is an innovative, flexible consumer lending solution that allows for fast decision-making and gives users access to funds right when they need it. It has been ranked by Deloitte as 64th in their Technology Fast 500 ranking for North America.
Extending an MVP with new features
We started working on Acima’s product in its MVP stage, and continue scaling it up to match its business growth.
Adding integrations with external systems
The platform relies on supporting external solutions, integrated through the custom API we built.
Building a leasing management system
Acima’s team needed to easily manage new requests from customers and seamlessly process payments.
Eliminating tax calculation errors
Our custom solution verifies calculation results from external automated tax compliance software.
I have to admit, when I first started working with the iRonin team I was skeptical of offshore dev teams based on my past experiences. I can now say that iRonin has exceeded every expectation I had for them and they continue to impress me. They are an integral part of our software development team.

Fast and fully transparent personal loans for subscribers

Creditspring offers a subscription-based model for secure, lightning-quick loans. It’s an entirely new personal finance model, in which users gain access to a number of guaranteed, on-demand loans per year, with no hidden costs and full transparency.
R&D and Proof of Concept development
We researched various options to ensure that our solution would serve the client’s business needs.
A refined administration panel
We improved the UI, added new features and integrated the panel with Zendesk for better data presentation.
Custom configuration for data logging
The app was hosted on Heroku, so we made it possible for the client’s Datadog system to be hosted there, too.
Time travel testing
We shifted the app’s timeline to test for issues that might come up for long-term users months down the line.
We hired iRonin.IT with the goal of augmenting our in-house development team to build new functionalities for our front office and back office systems. iRonin.IT's skilled team of developers were crucial to the success of the project. Their collaborative approach supplemented their professional management style.
