Replace aging software with AI-native apps you own — or keep what works and supplement it with agents and modern tooling. Either way: AI-accelerated, no vendor lock-in, and a team that stays.
See how Slingr modernizes the systems your business runs on — without the rip-and-replace.
For a decade, building custom meant long timelines and big budgets — so you rented SaaS and bent your operation around someone else's roadmap, or you kept a homegrown system alive long past its prime. AI-accelerated engineering has collapsed that cost. What used to take a quarter now ships in weeks.
Meanwhile the systems you actually depend on are aging out — apps written in VB6, PowerBuilder, classic ASP, or FoxPro, and SaaS contracts that renew higher every year. A retiring maintainer, a compliance deadline, a new owner, or an AI initiative blocked by legacy infrastructure turns that quiet risk into an emergency. Modernizing is no longer the expensive option. It's the cheaper one — and the only one that leaves you owning what you run on.
We don't chase shiny demos. Our expertise is the boring, business-critical workhorses your operation can't run without — the systems on the shop floor, in the back office, in the lab. We build them to enterprise security standards (SOC 2 Type II, HIPAA), and we stay: most of our clients have worked with us for years, not months.
Some teams are ready to retire a system only one person fully understands. Others depend on something that still works and can't risk touching it. Modernization isn't all-or-nothing — we meet you where you are, and you own everything we build.
Nothing gets ripped out. We wrap the systems you already trust — ERP, homegrown apps, the SaaS you're stuck with — in agents, integrations, and lightweight micro-apps that add the automation and AI they were never built for. Your stack stays; it just stops holding you back.
For a core system in VB6, PowerBuilder, COBOL, classic ASP, or FoxPro that's become a liability. Agent-assisted refactoring preserves the business logic you depend on and rebuilds it — supervised by senior engineers, at 50–60% of traditional cost and time. You own the source code outright.
Source code, data, and infrastructure — all yours, outright. Clean, fully documented, no hostage situation. Bring your own team whenever you want.
No license to renew, no per-seat tax that climbs every year, no roadmap you don't control. You keep the asset, not a subscription.
Built around agents and automation from the ground up — not bolted on. Delivered at 50–60% of traditional cost and time, every line reviewed by senior engineers.
SOC 2 Type II and HIPAA compliant. We understand the security and audit requirements of the enterprise — and we build to them, not around them.
We build it, run it, and maintain it — your application, our operational responsibility. Most clients stay with us for years, not months.
AWS, GCP, Azure, or on-prem. Your application runs where it makes sense for your business and your compliance requirements.
Slingr is a verified Google Cloud Technology Partner. We design AI into your application from day one — Gemini, Vertex AI, the whole Google AI stack — running on the same infrastructure that powers Search and Gmail.

We don't sell hours — AI has made time a bad proxy for output. Instead, pods are sized by the complexity of what you're building and how fast it needs to evolve.
All Build pods include architecture, development, deployment, and documentation. No setup fees. Month-to-month — cancel anytime. Your code and infrastructure are always yours.
*Third-party service costs — including cloud hosting, APIs, and AI tool usage — are billed separately by their respective providers.

"From a technical standpoint, we need people who know what they're doing, who are willing to adapt and iterate quickly. Slingr delivered exactly that."
"It's not easy to set up a system that can track, share, and automate the growing amount of data being generated in a modern lab. Slingr made it possible."
"Slingr brought the execution discipline we preach to our own clients. They scoped it fast, built it right, and delivered on a timeline that most dev shops would call impossible."

Book a CallYou don't have to rip out anything. Slingr surrounds your existing stack with agents that handle the work your team does today. Over time, lightweight micro-apps absorb the modules that have gone redundant. Eventually you drop licenses you no longer need — and keep the data that was always yours.
Nothing gets touched. Salesforce, NetSuite, Workday — whatever you have stays. Slingr builds the agentic layer that reads from your systems, writes to them, and starts handling the work humans were doing by clicking through screens.
Once agents are doing the work, parts of your monolith stop earning their keep — a reporting module nobody opens, a workflow engine nobody configures. We stand up lightweight micro-apps that absorb those functions, one at a time.
When enough of the monolith is hollow, the renewal conversation changes. You don't need the enterprise tier. Eventually you don't need the system at all — you keep the data and drop the license.
