PRAGMATIC AI SOFTWARE CONSULTANCY

AI should be actionable.Outcomes over hype.

We create software solutions powered by AI to solve real business problems and drive results that matter.

AI Proof Sprint
AI Traction Sprint
Accelerate Legacy Modernization with AI

embedded AI proof sprint for software teams

Pinpoint the highest impact area for AI and build a working example—all in two weeks.

Most AI initiatives stall between executive ambition and what teams can ship. The gap between how you work and how you could work widens every month. The AI Proof Sprint embeds two Test Double double agents inside one team for two weeks to replace assumptions with evidence, at a $25,000 fixed rate.

What's included:

  • Baseline and opportunity map: AI capability read, prioritized list, and a "not now" list
  • Live proof: one top opportunity solved with AI
  • Curated workflows: skills, agent patterns, and automations that clicked, documented for reuse
  • 90-day path to capability: measurable targets, pilot checkpoints, and visibility mechanisms to compound early wins

You get senior consultants who start with business problems and technology, not trainers running exercises. We build with your team on their real work so they own the skill, not just the artifact.

ADVANCE AI TRACTION SPRINT FOR SOFTWARE ENGINEERING TEAMS

Build quality software faster, with AI approaches that work for your team.

A few engineers are doing remarkable things with AI. Most treat it like autocomplete. Some aren't touching it. The gap between your best AI users and everyone else is widening. The usual signals—seat counts, survey scores, anecdotes—don't tell you why or what to do about it. The AI Traction Sprint embeds two Test Double double agents with one team for two weeks to measure the gap and start closing it on live work, at a $25,000 fixed rate.

What's included:

  • Capability baseline: where each engineer lands on our AI fluency rubric, scored through real interaction rather than self-report
  • Opportunity map: prioritized list of where AI would move the needle, plus a "not now" list
  • Live proof: one high-impact opportunity worked alongside your team, so the gap closes on real code
  • 90-day path to capability: measurable targets tied to the rubric, checkpoints, and visibility mechanisms that compound gains

Stop guessing whether AI is making your team better.

ACCELERATE LEGACY APPS WITH AI

Untangle legacy systems fast with AI, and make them more maintainable.

Are legacy systems not moving as fast as the business needs, but your team can’t dedicate enough time to renovating them?

Our experienced software and product consultants combine AI tools with technical expertise to accelerate legacy software:

  • Faster onboarding in legacy apps via AI analysis and documentation
  • Accelerate Rails upgrades with AI driven source code changes
  • Rapidly identify complexity hotspots in codebases to prioritize improvements
  • Automated test suite design and development made even faster to characterize functionality
  • Clean up AI slop messes and tech debt (it happens!)

We dive in to clean up the funky stuff, and guide your team on leading practices to avoid creating nightmare codebases in the future. AI tooling is paired with sound judgement from pattern matching across hundreds of clients to make your legacy modernization and Rails upgrades faster, easier, and trustworthy.

Quality you can’t generate: AI is only as good as your constraints

AI changed the cost structure of software. It didn't change the value structure. The value is no longer the code you write. It's the taste, judgment, and constraints you encode into the system that shapes what AI produces.

Anyone can code: Software Is having its Ratatouille moment

Gusteau said it best: "anyone can cook", and now, "anyone can code." LLMs and agentic coding are the Remy to our Linguini. Our job isn't to guard the kitchen—it's to help others cook something worth serving.

5 rules to avoid the 95% AI project failure rate

MIT research shows 95% of corporate AI pilots fail. The problem isn't the technology—it's transformation. Based on decades of implementation experience, here are the 5 non-negotiables every C-suite needs to master for AI success.
