THE NAME

NEXUS3

The Intersection of Opportunity

A nexus is an intersection, a convergence point where forces meet and create something greater than any one of them alone. We sit at the center of three powerful forces reshaping entire industries:

01 / TECHNOLOGY INNOVATIONS

AI capabilities that now match or exceed human performance in knowledge work

02 / MARKET SHIFTS

Entire industries at the tipping point of mandatory AI adoption

03 / DATA ABUNDANCE

Decades of digitized industry data now finally usable by AI systems—the raw material for intelligent automation

Nexus3 Knowledge Graph

OUR THESIS

NEXUS3 BUILDS AND OPERATES AI-NATIVE COMPANIES IN OVERLOOKED VERTICALS. WE OWN THE OPERATING LAYER, NOT JUST THE SOFTWARE, SO EACH COMPANY WE BUILD MAKES THE NEXT ONE FASTER.

"Most AI companies sell software to businesses. We are the business—AI-native from day one."

For every dollar spent on software, six dollars are spent on professional services. AI agents can now do that work—and we own the companies delivering it.

We build where agentic systems can replace entire scopes of work, fueled by proprietary technology and compounding data advantages.

THE NEXUS3 PLATFORM

FROM THE FOUNDERS

A LETTER FROM TIM & JOHN STOJKA

"We've been building technology companies since before the dot-com wave. We've seen every cycle: mobile, SaaS, cloud. Each one rewarded the people who moved early and stayed focused.

AI is different. It changes who can do what. A small team with the right systems can now deliver the output of a department. That reprices every professional services business on the planet.

We're not here to sell picks and shovels to the people looking for gold. We're here to own the mines.

The companies we build will be hard to replicate. Not because we'll move first (though we will) but because the data we collect, the relationships we build, and the systems we compound will be barriers that take years to match.

That's the bet. We're all in."

CAREERS AT NEXUS3

WE'RE BUILDING THE COMPANIES OF THE FUTURE.

Small teams. Big problems. Real outcomes.

We're looking for engineers who want to build systems that actually run companies, strategists who can spot opportunity in complex industries, and domain experts ready to reinvent how entire sectors work. Not a research lab. Not a consulting firm. A team of builders.

METHODOLOGY

HOW WE BUILD COMPANIES

THREE PEOPLE. ONE THESIS. AN AI OPERATING LAYER BEHIND THEM.

Every Nexus3 company starts the same way: a domain expert who knows where the real pain is, an engineer who develops prototypes that can replace entire workflows, and a business development lead who turns early traction into revenue. These teams are supported by the greater Nexus3 ecosystem of experienced operators and technologists.

01

DOMAIN EXPERT

Deep industry expertise, relationships, and context that can't be faked. They know where the real pain is and they have the trust of the market to get in the door.

THE INSIDER

02

AI ENGINEER

Works closely with the business development team and domain experts to develop POCs in real time. They are constantly iterating the prototype and make use of novel tech developed within NX3 Labs.

THE TECHNICAL EDGE

03

BUSINESS DEVELOPMENT

Finds the signals others miss. Develops relationships and understands customers in order to identify what needs to be built.

THE CONNECTOR

04

NEXUS3 ECOSYSTEM

Teams are supported by and benefit from Nexus3 Capital and NX3 Labs. Insights are shared, information moves fast, and mistakes are never repeated.

THE MACHINE

WHY THIS MODEL WORKS

SPEED

Small and efficient teams win when they are uninhibited by layers of bureaucracy.

LEVERAGE

Outcome-based pricing means revenue scales with value delivered. As the AI improves, margins expand automatically. That's the flywheel that makes Nexus3 companies worth building.

THE PLAYBOOK

WHERE WE BUILD

INDUSTRIES WE LIKE

"For every dollar spent on software, six are spent on services. We target industries where AI agents can deliver the work, not just the tool, and where the data compounds into a moat no competitor can buy."

LEGAL: SPECIALTY & MID-MARKET

Humans tirelessly read complex documents, compare obligations across multiple sources of truth, and turn context into repeatable legal work.

HEALTHCARE REVENUE CYCLE

Humans chase authorizations, correct codes, appeal denied claims, and reconcile payer rules across systems that rarely agree.

INSURANCE

Humans gather forms, interpret policies, compare evidence against damage schedules, and move claims or submissions through repetitive workflows.

ENERGY: REGULATORY INTELLIGENCE

Humans monitor dockets, read filings, extract obligations, and connect regulatory changes to operating decisions across fragmented sources.

ACCOUNTING & TAX

Humans collect records, reconcile accounts, classify transactions, and repeat close and tax workflows under constant deadline pressure.

THE PATTERN WE LOOK FOR

→ Massive outsourcing budget exists
→ Work is intelligence not judgment
→ Laborious, repeated workflows dominate the workday
→ Data compounds into advantage
→ Outcome-based pricing accepted

PILLAR 01

NEXUS3 OPERATING COMPANIES

WE BUILD THE COMPANIES. WE RUN THEM.

Nexus3 operating companies are built from the ground up as AI-native businesses. Each one is purpose-built for a specific industry vertical, powered by autonomous systems that handle the work humans used to do manually.

PORTFOLIO SPOTLIGHT

HEXIOS

COMMERCIAL REAL ESTATE

Your lease portfolio, fully actionable. In minutes.

Hexios extracts, reconciles, and audits commercial leases with AI so property teams spend less time buried in documents and more time recovering revenue they're owed. Managing a commercial portfolio means tracking hundreds of lease obligations, billing tenants accurately, and reconciling CAM charges, while making sure nothing slips through the cracks.

Instant Lease Abstraction Automated CAM Reconciliations Portfolio-wide accuracy Full audit trail
VISIT HEXIOS.AI →

THE PROBLEM

Commercial lease abstraction and CAM reconciliation is done manually today; an error-prone, time-consuming process that leaves significant revenue on the table.

THE SOLUTION

AI agents extract, reconcile, and audit leases with precision, delivering the completed work product rather than a tool to help humans do it.

THE MODEL

Outcome-based pricing means revenue scales with the value we create for each client, and margins expand as the AI improves.

PILLAR 02

NX3 LABS

MOST AI COMPANIES ARE BUILDING WRAPPERS.
WE'RE BUILDING THE INFRASTRUCTURE UNDERNEATH.

NX3 Labs is the research and development arm of Nexus3. We push on the hardest problems in agentic AI: knowledge graphs, memory, retrieval, autonomy. We experiment boldly, prototype rapidly, and explore relentlessly. We don't expect most experiments to ship... but the ones that do can change everything.

01

KNOWLEDGE GRAPHS

AI agents with structured understanding of business relationships, dependencies, and logic, moving far beyond RAG into genuine contextual reasoning.

STRUCTURED REASONING

02

MEMORY-EFFICIENT ARCHITECTURES

Autonomous agents that operate at scale without burning through compute: lean, fast systems that run continuously in production, not just in demos.

PRODUCTION-GRADE AI

03

ADVANCED INFORMATION RETRIEVAL

Systems that understand what you actually mean, combining deep language understanding with precise structural parsing to surface exactly the right information at the right moment.

PRECISION AT SCALE

PILLAR 03

NEXUS3 CAPITAL

WE LOOK FOR COMPANIES WHERE AI ISN'T A FEATURE. IT'S THE ENTIRE BUSINESS.

Most investors just write checks. We've built and operated tech companies ourselves. When you take capital from Nexus3, you're bringing on a team that has done the work, not studied it.

01

MORE THAN CAPITAL

We bring more than money: technology, agent infrastructure, and operational knowledge. When you partner with Nexus3, you get the NX3 Labs AI platform, the operating playbook, and the network, not just the check.

02

OPERATOR ADVANTAGE

We're builders, not just investors. We've started companies, hired teams, found product-market fit, navigated enterprise sales, and scaled revenue. We've made the mistakes so you don't have to.

03

EARLIEST STAGES

We invest when the idea is bold, the team is sharp, and conventional wisdom says too soon. That's where the real returns are, and we don't wait for proof, we help build it.

PHILOSOPHY

VITAMIN TO PAINKILLER

"We don't build vitamins — products that are nice to have but easy to ignore. We build painkillers. Products that solve real, urgent problems and become essential to how our customers work."

THE DIFFERENCE

The difference comes down to process. We enter a domain, build a thesis, and develop a working prototype — but that's just the starting point. The real work is understanding how our customers actually solve problems today, then iterating until our product becomes more valuable to them over time.

ENTERPRISE MARKETS

In enterprise markets, that means navigating multiple stakeholders, learning how they operate, and building software that makes their workflows fundamentally more efficient. It's not about adding features — it's about eliminating pain.

THREE DECADES OF PROOF

This is the approach we've applied across three decades of company building, from the early days of ecommerce to energy data analytics to AI-driven vertical software. Each time, the principle is the same: get deep into the domain, find the real pain points, and build products that customers can't live without.

THE NEXUS3 STANDARD

VITAMIN

  • → Nice to have
  • → Easy to ignore
  • → Adds convenience
  • → Optional in the workflow

PAINKILLER

  • → Solves a real, urgent problem
  • → Becomes essential over time
  • → Eliminates pain from the workflow
  • → Customers can't live without it
