We build AI powered software and rescue AI generated codebases.

We've been writing production software for over two decades. These days most of that work involves AI, and we've gotten very good at it. If you need an AI product built from scratch, or you've got an AI generated codebase that's starting to buckle under its own weight, we can help.

[ SERVICES ]

[ AI PRODUCT DEVELOPMENT ]

BUILD AI POWERED PRODUCTS FROM SCRATCH

We build the kind of AI software that actually makes it to production and stays there. LLM powered apps, agent systems, automation tools, internal platforms. We know what it takes to go from a working prototype to something you can put real users on without losing sleep.

■ LLM powered apps (assistants, document processors, content engines)

■ AI agents and multi step workflow systems

■ Automation that replaces manual processes at scale

■ Existing platforms reimagined with AI at the core

■ Internal tools that make your team wildly more productive

Our AI stack:

Claude, GPT, open source models, RAG pipelines, vector databases, embeddings, fine tuning. On the engineering side: .NET, React, Next.js, Astro, Python, TypeScript. We use whatever fits the problem best.

[ AI CODEBASE RESCUE ]

YOUR AI GENERATED CODEBASE NEEDS SENIOR ENGINEERS

You used AI to build fast and it got you pretty far. But now the codebase is getting harder to work with, bugs are showing up in weird places, and your team spends more time fighting the code than shipping features. We see this constantly. We come in, figure out what's actually solid and what needs to go, then fix it incrementally without blowing everything up.

Problems we see in almost every AI generated codebase:

■ Inconsistent architecture (every file was generated in a different chat session)

■ Security holes and edge cases the AI never thought about

■ Tests that exist but don't actually test anything useful

■ Random dependencies, version conflicts, abandoned packages

■ The same logic copy pasted and slightly different in ten places

How we approach it:

We start with a full audit so everyone knows where things stand. Then we triage by risk, stabilize the worst parts first, add real test coverage and monitoring, and work from there. No big rewrites. Just steady improvement on a codebase that keeps running the whole time.

[ AI INTEGRATION ]

MAKE YOUR EXISTING SYSTEMS SMARTER

Not everything needs to be built from scratch. Sometimes the smartest thing to do is plug AI into systems you already have running. We've done a lot of integration work over the years, so we know how to get AI working inside real production infrastructure without breaking what's already there.

■ AI powered search (semantic understanding across your data)

■ Document processing (extraction, classification, summarization)

■ Internal AI assistants trained on your own docs and processes

■ Workflow automation with AI decision making baked in

■ Data pipelines that use AI to enrich, classify, and route

[ ABOUT US ]

[ WHO WE ARE ]

We're an AI native development shop based in Stockholm. We've been around for a while, and for the past few years AI has been at the center of pretty much everything we do.

We didn't just add "AI" to our website last year. We use it every day to build and ship real software. We understand its output, we know where it's strong, and we know exactly where it falls apart and needs an experienced engineer to step in.

[ OUR EDGE ]

Most of the AI development shops out there were founded in the last couple of years. They're fast, but they haven't had to maintain anything in production for very long. Meanwhile, most traditional agencies have tons of engineering experience but still treat AI as a bolt on feature.

We've got both. We're senior engineers who went all in on AI, so we bring the production discipline (monitoring, testing, security, deployment) and the AI fluency together. The stuff we build doesn't just work in a demo. It works at 3am when nobody's watching.

[ FREQUENTLY ASKED QUESTIONS ]

Q: What does Triple Down do?

We build AI powered products from scratch, take over AI generated codebases that need proper engineering, and plug AI into existing systems.

Q: What is AI Codebase Rescue?

A lot of companies used AI to generate entire codebases over the last couple of years. Many of those codebases look fine on the surface but have real problems underneath: messy architecture, security gaps, no tests, dependency chaos. We come in, audit the whole thing, fix what needs fixing, and stay on to maintain it. No full rewrites necessary.

Q: What AI technologies do you work with?

Claude, GPT, Llama, Mistral, and whatever else makes sense for the project. On the infrastructure side we work with RAG pipelines, vector databases, AI agents, fine tuning, and more. We're not married to any single vendor or model.

Q: Why should I hire you instead of a bigger agency?

Bigger agencies have a lot of people but most of them just slapped "AI" on their pitch deck last year. We actually build with AI every single day, and we've got the production background to back it up. You get senior people doing the actual work, not juniors following a playbook.

Q: How experienced is your team?

We've been around since the early 2000s. We've built fintech compliance platforms, e learning systems, streaming services, HR competency platforms, air taxi apps, and now the AI products we're focused on today.

Q: How do you handle data security?

Very carefully, especially with AI systems that touch sensitive data. We follow GDPR, set up proper access controls, and pay close attention to AI-specific risks like prompt injection and output validation. If your data matters (and it does), we treat it that way.
