Senior technical leadership. AI that survives the audit.
KYE Ventures provides fractional CTO work, technical advisory, and AI consulting and services for companies that need senior technical leadership without a full-time hire.
I'm Nathan Biles. I've spent 25 years building companies, and today I lead development with teams of AI coding agents working in parallel, so I know firsthand what AI changes and what it doesn't.
What AI changes, and what it doesn't
What changes
How fast a small team can ship.
One senior engineer can direct several agents at once, when the work is well specified.
Where the time goes.
Less typing. More deciding what to build, reviewing what came back, and testing what matters.
The cost of trying things.
A prototype is hours, so you test an assumption instead of arguing about it.
What senior means.
The job is judgment: scoping, review, architecture, and knowing when the output is wrong.
What doesn't
Someone is accountable for what ships.
Agents don't carry the pager, and they don't sign the audit.
Architecture still decides what is possible later.
Fast code on a bad foundation is still a bad foundation.
Compliance is still evidence.
SOC 2, HITRUST and HIPAA want controls, logs and proof, not a demo.
Your people still matter.
The team's habits, reviews and trust decide whether AI makes you faster or just busier.

Services
Six ways to work together. Each starts with a short, fixed-scope look at where you really are.
- Compliance-ready AIAI-assisted development, architecture and controls designed so your company passes its own SOC 2 and HITRUST audits and meets HIPAA requirements, without giving up the speed.
- Fractional CTOA CTO on retainer: the architecture, the hiring, the vendor calls and the board conversation, for a company that is not ready to hire one full time.
- Technical AdvisoryA senior second opinion on architecture, AI, build-or-buy and team decisions, for leaders who have a CTO or are about to become one.
- AI consulting and implementationFrom "we should do something with AI" to a working system your team runs, with honest answers about what it can and cannot do.
- Application DevelopmentWeb and mobile software built by a senior engineer directing AI coding agents, from the first version to a product that runs in production.
- Code ModernizationBring an older system to a state your team can change safely: tests, structure, upgrades and a path off whatever is holding you back.
Method
Every engagement runs the same way, whether it is an assessment or a year on retainer. The first phase is the one most technical work skips.
Phase 1: Ethos Discovery
Understand what the company believes and is for, before deciding what to build.
Phase 2: Design
Write the decisions down: the shape of the system, the controls, and what gets built first.
Phase 3: Build and review
AI coding agents work in parallel. A senior engineer specifies, reviews and tests what they produce.
Phase 4: Run and hand over
Operate it, prepare for the audit, and leave the team able to change it without me.
The record
Credibility here comes from the record, not from adjectives. Nathan has built software for regulated industries like banking, security and employee benefits.
- CTO, TZ UnitedThe U.S. partner for institutions building on the Tezos blockchain.
- ClickEngine, now powering CIMAThe attribution platform Nathan built in 2019, now the foundation of an AI-first marketing platform for mortgage lenders.
- CTO, TendA neobank serving the U.S. and Mexico, with deposit accounts in both countries.
- Open Threat Exchange, AlienVaultBuilt OTX from zero to over 100,000 users. AlienVault was acquired by AT&T.
- Architect, security startup backed by Michael DellIts merger into Secureworks became Taegis.
Bring the decision you are stuck on, or the system that is.
