Services we provide
AI & ML Development
Production-ready AI, ML, RAG, and computer vision, integrated into your stack. We build on OpenAI, Anthropic, Gemini, Llama, Mistral, DeepSeek, Qwen, and more, and turn your data into secure, measurable revenue gains, not pilots that gather dust.
AI Agents Development
Custom agents, copilots, and multi-agent systems that automate real work: sales, support, ops, research. Production-grade from day one, with guardrails, evals, and observability built in.
Custom Software Development
Custom software with AI acceleration: web, mobile, and SaaS products engineered end to end, with AI built into every layer when your product calls for it, from conversational UIs to recommendation engines and agent-first workflows.
AI-Native Transformation
Turn your engineering organization AI-native without rebuilding what works.
AI-Driven Product Discovery
Validate scope, architecture, and ROI before committing to a full build. Go from hypothesis to a working PoC in 1–2 weeks, with use-case mapping, a data audit, and a costed roadmap.
Team Augmentation
We embed top 1% senior AI/ML, full-stack, and product engineers directly into your team, working AI-first by default. Our experts adopt your tools, stack, and culture, adding senior capacity without long hiring cycles.
Web Development
Modern websites and web apps built by senior teams: fast, responsive, and easy to manage. Add AI agents, copilots, or data integrations when you need them, or simply ship a great website.
Mobile Development
Native and cross-platform iOS and Android apps built by senior teams. AI features (agents, copilots, voice, computer vision) when your roadmap calls for them, and solid, fast, well-loved apps either way.
Diffco AI Methodology
A delivery method built for the AI era, not retrofitted to it.
Code is the cheap part now. Knowing what to build first, which foundation will hold at ten times the users, and what not to build at all is where projects are won.
Senior engineers make those calls. More than 100 AI agents per engineer do the building, around the clock, on our own delivery platform built on Claude Code and OpenAI Codex. A living plan with automatic checks keeps every agent inside the lines.
- You click through your product before we build it
- We bring you the parts of the job you never put into words
- Every architecture decision is written down with the alternatives
- Everything traces back to a goal, which is what makes change fast
- People make the decisions, and AI agents build inside them
- Before release, a person watches it work
- The whole project
is a document you can read

How Diffco helps you
deliver the best results
Product‑Oriented
Approach
We think like product owners, not just vendors. We research your users, challenge assumptions, and help you prioritize features that move the metrics that matter.
AI-First by
Default
Every project runs on our Production-Ready AI Engineering practice: senior engineers paired with AI agents, shipping faster without lowering the bar. AI is the engine, not the marketing.
Clear
Communication
We build relationships on integrity and trust, with transparent processes and proactive communication at every stage of the work.
Customer-Centric
Approach
We start from your business goals, not our tech stack, and deliver tailored solutions that drive measurable impact for your team and customers.
How we build
Seven stages, with a person signing off at every gate.
Every project runs through Production-Ready AI Engineering: seven stages, senior engineers directing 100+ AI agents, a check on every save, and a person signing off at every gate.
- 01
Discover
Human + AIWorkshops and stakeholder interviews with AI in the room. It cross-verifies inputs across calls, docs, and Slack threads, flagging blind spots, edge cases, and contradictions humans miss.
- 02
Plan
AIAI decomposes the work, picks architecture, models, and tools. Surfaces risks, costs, trade-offs, and conflicts between stated requirements, before they become bugs.
- 03
Align
HumanYou review and approve. Every decision is logged: an auditable trail before any code is written. No black box, no scope drift.
- 04
Build
Human + AIAI agents execute the approved plan inside engineered guardrails. Senior engineers steer and unblock. Sprint cadence with working artifacts, not status decks.
- 05
Validate
Human + AIThree independent layers on every release candidate: automated evals, senior code review, and dedicated Human QA, with manual and exploratory testing alongside security, performance, and accessibility checks.
- 06
Release
Human + AIProduction deployment, UAT, knowledge transfer, runbooks. Cutover is documented, reversible, and on a schedule you approve. Your team takes the keys, or we operate it for you.
- 07
Evolve
Human + AILaunch is a milestone, not a finish line. Monitoring, feedback loops, and incremental improvements keep the system compounding, and feed the next discovery cycle.
Every later change re-enters the same loop, and nothing skips a step.

The AI Moderator: AI-run interviews plus the real-time participant interface
We've developed an audio marketing platform with intelligent advertisements
We were impressed by Diffco's approach to the development process and how they engineer new solutions.
Full development + AI agentic product discovery
Diffco partnered with Happier to provide full product development and AI-driven agentic product discovery for their emotional wellness platform. We led end-to-end engineering across mobile and backend, and used AI agents during discovery to map user behavior, generate product hypotheses, and validate them against real user data, turning daily check-ins, mood patterns, and content interactions into personalized, evidence-based wellbeing experiences at scale.
We set up AI-native development across RedTrack's ad-tracking platform
RedTrack already had Claude Code running in CI, a custom orchestration service and context files, and a productivity curve that had flattened anyway. Diffco ran a month of Discovery, found the bottleneck was context rather than code generation, and installed the operational and methodological foundations around it: specification-driven development, documentation on hard CI/CD gates, and isolated per-task agent workspaces.
