N°001 — Services
Every capability you'd hire a CTO, an agency, and a design studio for. One team.
Full Stack Build
Idea to production in 4–8 weeks — a complete senior team that designs, builds, and launches with you.
Whether you're a founder pre-seed or an executive spinning up an internal venture, you get a dedicated team of senior engineers, a product designer, and a technical lead who has shipped at scale. We use AI-accelerated workflows to move at twice the speed of a traditional build, without cutting the corners that kill products six months in.
What you get
- Production-ready product in 4–8 weeks
- Launch-ready architecture that scales past v1
- Design system and product design included
- Weekly demos from week one
AI Development
Agents, LLM integrations, and AI-native platforms — shipped to production, not stuck in demos.
Every engineer at Key works AI-native by default, and this is where that shows. We design and build agentic workflows, LLM-powered features, retrieval and data pipelines, and the evaluation and governance layers that make them safe to run.
What you get
- Agentic workflows and LLM integrations
- Retrieval, data pipelines and evaluation
- Model selection and cost engineering
- Governance and observability built in
Staff Augmentation
The top 1% of engineers from Google, Meta, and Amazon — vetted by founders, embedded in your team.
Don't hire headcount; acquire capability. Every candidate is pre-vetted — ex-FAANG engineers and senior operators, not scraped from a job board. Full-time or fractional, and you only pay when the placement works.
What you get
- Vetted by founders, not recruiters
- First candidates within days, not months
- Success-fee based — aligned incentives
- Full-time and fractional options
Consulting & Expert Services
Senior operators in the room when the stakes are high — without a long-term retainer.
Some problems need judgment more than headcount. We run technical due diligence for investors, evaluate vendors and build-vs-buy decisions, shape product and platform strategy, and deliver workshops that leave your team sharper than we found it.
What you get
- Product and technology strategy
- Technical due diligence for investments
- Vendor and build-vs-buy evaluations
- Workshops and architecture audits
Design & Media
Product design that ships — not just pretty mockups that die in handoff.
Our designers work the way engineers wish designers worked: systems-first, prototype-driven, and fluent in what's buildable. From brand identity to full product UX to the media assets that carry your story.
What you get
- UX/UI and end-to-end product design
- Brand, visual identity and media production
- Design systems built for engineering
- Prototyping and user research
Growth & Marketing
Positioning, go-to-market, and demand generation — turning what we build into measurable traction.
Shipping is half the job; getting it adopted is the other half. We shape positioning and messaging, build GTM plans grounded in your actual funnel, and run content and demand generation that compounds — the same operators who've taken products to market at scale.
What you get
- Positioning and messaging that lands
- GTM strategy tied to your funnel
- Content and demand generation
- Launch playbooks and analytics
