Fractional CTO and AI engineering for B2B companies scaling $10M → $150M+. Led by the Director who built the AI/BI systems that took a telecom brokerage from $50M to $150M — and still self-hosts the production stack he'd be selling you.
The executive who still codes. Dual MBA + MS, SuiteWorld speaker, 2X President's Club, and one of fewer than 1,000 developers worldwide running Graphiti knowledge graphs in production today. Every week you wait is money left on the table.

9o4t Inc is a fractional CTO and AI consulting firm led by David Cullum — a technology executive with 15+ years scaling B2B revenue through AI, business intelligence, and software engineering.
As Director of AI & BI at a $150M telecom brokerage, David built the systems that scaled revenue from $50M to $150M, led three technical teams, and shipped a custom partner platform to the App Store and Google Play.
We specialize in CRM and ERP architecture (NetSuite SuiteScript, Salesforce, HubSpot), production AI and knowledge graphs (Graphiti, FalkorDB, LightRAG, Ollama), and process automation (n8n, RPA, commission tracking).
Most consultants are either executives or engineers. David is both — a dual MBA + MS leader who still self-hosts production infrastructure and ships code weekly.
Executive technology leadership plus hands-on engineering — across six high-impact disciplines.
Executive technology ownership on a monthly retainer. Strategy, architecture, vendor selection, team building, and hands-on delivery for B2B companies scaling $10M–$150M+.
n8n is the glue, not the CRM. We wire your CRM, ERP, inbox, Stripe, and Slack together and automate the handoffs that eat your team's day — self-hosted on Railway, owned by you.
Production Graphiti + FalkorDB knowledge graphs and LightRAG / Ollama RAG pipelines built on top of your existing CRM/ERP — without ripping it out. First-mover pricing window.
Implementation, customization, and integration — NetSuite SuiteScript development by a SuiteWorld speaker. Tri-platform fluency is rare; we have it.
Data pipelines, executive dashboards, predictive lead scoring, and telecom channel commission auditing. 2X President's Club recognition. Get paid what you're owed.
Full-stack web apps and native iOS / Android mobile builds. Proven App Store and Google Play deployments — a B2B partner portal in production for 7+ years.
Most consultants specialize in one lane. Ours is four skill combos that are extraordinarily hard to hire for — and harder to clone.
Directors who scaled a company from $50M to $150M almost always delegated every line of code years ago. David still self-hosts production infrastructure while leading three teams. This is what PE-backed portfolios and bootstrapped founders pay Catalant and A.Team premium rates for: an operator who sets strategy and ships it.

NetSuite is 2000s-era ERP. AI/ML and native mobile are the modern stack. Almost no one spans both. We integrate predictive models and RAG pipelines into existing NetSuite instances, then ship the field-facing iOS/Android app that consumes them — without forcing a rip-and-replace.

Graphiti shipped in late 2024. Fewer than 1,000 developers worldwide have it in production today. Pair that with a decade inside Salesforce and NetSuite and you get the rarest bridge in B2B AI: a knowledge-graph intelligence layer on top of existing CRM/ERP — unlocking unstructured data without migrating off the platform of record.
Buyers: Enterprises with unstructured-data problems on Salesforce/NetSuite
DevOps engineers rarely sell. B2B salespeople rarely self-host. We do both — scoping the deal (sales), standing up the n8n + Railway + Postgres stack (engineering), and supporting it (DevOps). One throat to choke, zero translation tax, and a 2X President's Club receipt for whether the systems actually move pipeline.

Outcomes from real engagements — the kind your competitors hope you never see.
Led AI and BI systems that grew a telecom brokerage from $50M to $150M over 7 years — roughly $14M of incremental revenue per year.
Custom partner platform shipped to web, iOS App Store, and Google Play — passed Apple and Google review and served real users in production.
Led robotic process automation initiatives at $150M scale, delivering significant recurring expense reduction across operations, finance, and partner onboarding.
Earned top-tier sales recognition twice — as a BI/systems Director, not a salesperson — by innovating sales training and analytics-driven processes.
Featured speaker at NetSuite's flagship annual conference (10,000+ attendees) on driving sales and user adoption of NetSuite CRM.
Running Graphiti + FalkorDB knowledge graphs, LightRAG, and Ollama in production today — bleeding-edge tech with fewer than 1,000 developers worldwide shipping it.
Two sister products running on the exact stack we sell to clients. Proof, not promises.
One-shot M&A partner/customer overlap analysis for acquirers and PE deal teams. Upload two lists, get a 24–48 hour report with overlaps, duplicates, conflicts, and confidence scores. Also a self-serve SaaS for sales ops teams drowning in conference-lead deduping.
A public showcase of our knowledge-graph stack built on a 5-year, 14,000-article dataset. Proof that Graphiti + FalkorDB + LightRAG aren't pitch-deck vaporware — they're shipping production systems today. Search, visualize, explore.
Sized to where you are today — and built to start moving the number this quarter, not next year.
Monthly retainer · 20–30 hrs/mo
Executive technology ownership without a full-time hire. Strategy, architecture, vendor selection, team building, roadmap, and hands-on delivery — on a cadence your CFO can budget.

When you need delivery, not just direction: we stand up production systems — partner portals, AI automations, data pipelines, mobile apps — and hand them off or run them ourselves.
