Slingr is an AI-native custom software development company headquartered in Miami, Florida, with nearshore engineering offices in Mendoza and Buenos Aires, Argentina. Since 2011, we have built enterprise software for mid-market and enterprise companies. Today, 120+ engineers deliver custom applications, AI agents, ERP integrations, and legacy modernization — software our clients own outright instead of renting SaaS.
We engage in two ways. Reinforce it: keep the systems that still work (ERP, homegrown apps, SaaS) and surround them with AI agents, integrations, and lightweight micro-apps that close the gaps. Replace it: rebuild VB6, PowerBuilder, FoxPro, classic ASP, or COBOL systems on a modern foundation using agent-assisted refactoring to preserve your business logic. Our methodology: Surround, Substitute, Sunset.
Senior engineers own the architecture and review every line of AI-generated code, so clients get AI speed and cost savings with production-hardened, documented software delivered in weeks, not quarters.
Industries: manufacturing, private equity portfolio companies, healthcare, life sciences and labs (LIMS, genomics), logistics, insurance, and law firms. Our specialty is business-critical systems: the shop floor, the back office, the lab.
At handover, clients own the source code, their data (on dedicated resources, never pooled), the framework it runs on (Apache 2.0), and agent-ready specs any team or AI coding agent can pick up. We host and run applications on Google Cloud or on the cloud and region compliance requires. Slingr is SOC 2 Type II and HIPAA compliant and a Google Cloud Partner.
Pricing is month-to-month pods, not hourly: Build ($6,000/month), Scale ($10,000/month), Custom, and Care for live applications (from $3,500/month). We also offer nearshore team augmentation. Most clients have worked with us for years.

RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Many but here are the most salient for our business.
Program Scale
100 Global Gurus recruited, vetted, and approved on the platform within 8 weeks of launch
Guru profiles searchable and downloadable by industry, geography, and expertise — reducing identification time from days to minutes
Stripe integration enables self-paying students to register, pay, and begin the program in a single seamless flow
Timeline
Platform delivered within the two-month beta deadline, in time for the fall cohort launch
Team incorporated real-world feedback and expanded functionality for the spring cohort In just 2 weeks
In less than 12 months, platform is scaling to support triple the original number of participants
Operational Efficiency
AI-powered matching reduced mentor-student pairing from several days to minutes
Tag-based system allows admins to instantly sort and group Global Gurus into cohorts, and send targeted notifications to specific groups, eliminating manual list management and blanket messaging
Partner universities and organizations can independently manage their own students, track cohort progress, and review applications through a dedicated portal — eliminating the need to route requests through Open Mindset staff and enabling the program to scale partnerships without adding administrative headcount.
Engagement

Platform's professional design and demonstrated scalability accelerates partner decision-making, serving as a live proof of concept in every introductory meeting

Describe their project management. Did they deliver items on time? How did they respond to your needs?
Slingr delivered on time and on or under budget every month throughout the engagement. The team went above and beyond expectations at every stage — listening carefully to challenges described in non-technical terms and translating them into elegant technical solutions. They communicated effectively throughout, responding quickly to questions and needs as they arose. They were genuinely invested in the Open Mindset mission, bringing thoughtfulness, creativity, and initiative to every interaction. Collaborative, responsive, and exceptionally talented, the Slingr team is among the most dynamic and enjoyable I have ever worked with.
What was your primary form of communication with Slingr?
Virtual Meeting
What did you find most impressive or unique about this company?
What sets Slingr apart is their rare combination of speed, depth, and genuine partnership. They delivered a complex, enterprise-grade platform in two months without cutting corners on functionality or design — spanning AI-powered matching, e-commerce, LMS integration, partner management, and certification in a single cohesive product. Equally impressive is their ability to take a non-technical founder's vision and translate it into precise technical solutions without losing the human element of the program. Slingr didn't just build what was asked: They engaged with the mission, evolved the product based on real-world feedback, and functioned as a true extension of the Open Mindset team.
Are there any areas for improvement or something Slingr could have done differently?
No significant areas of improvement to note. Slingr met or exceeded expectations across every dimension of the engagement. For organizations without a technical background, building in a structured onboarding session at the start of the engagement to align on platform terminology and workflows early could accelerate the initial learning curve.

Our Story
Slingr has built enterprise software since 2011. Founded by CEO Grace Schroeder, we watched companies bend their operations around rented software and prop up systems only one person understood, so we built a different model: senior engineers supervise AI to deliver custom software in weeks, and clients own the code, data, framework, and specs. Our 120+ product engineers in Miami, Mendoza, and Buenos Aires are trusted advisors who learn your business, not ticket takers.
What Sets Us Apart
15 years building software businesses run on
Since 2011, we've built and run the systems companies depend on every day, for manufacturers, labs, and healthcare providers, including Veritone, ChemQuant, and Ritchie Bros. SOC 2 Type II and HIPAA compliant. Most of our clients have worked with us for years.
AI makes it fast. Senior engineers make it work.
AI lets us deliver in weeks what used to take quarters, at a fraction of the cost. But AI on its own writes fragile software. Senior engineers design every system and review every line, so what you get is tested, documented, and built to last for years.
It's yours. No licenses, no lock-in.
You own the software we build and all of your data, like any other company asset. No per-user fees, no renewals, no vendor holding your business hostage. If you ever want to bring it in-house or switch providers, everything they need comes with it.
