Writing on AI
in business.
Research digests, practical notes, and briefs on published cases — written so teams can find useful answers in search.
Where Jev fits in business automation.
Ticket routing, refund gates, alert triage, agent tool choice — high-volume judgments with clear options. Skip it when you still need a paragraph.
5 min readDecision models vs chat models in a real workflow.
Use a general LLM when you need language. Use a decision model when you need a branch. Mixing them up is how bills and latency explode.
5 min readWhat Jev is — and why it spread so fast.
TypeSafe’s System One model returns typed decisions, not chat. Vercel reported the fastest first-day AI Gateway adoption in its history.
6 min readTwo years of AI ROI: what moved.
Across McKinsey, BCG, and Stanford’s AI Index: adoption rose, enterprise EBIT stayed rare, workflow redesign and KPIs mattered.
7 min readLearn It Live cut tickets 40%.
Public Zapier case study: an e-learning team built a chatbot in about an hour and cut support tickets by 40%. Not Tiercel work.
5 min readWriting tasks got faster—and better.
Noy & Zhang (Science): 453 professionals, ChatGPT on writing tasks—about 40% less time and 18% higher quality.
5 min readSprint-based AI delivery.
Pick one workflow, set acceptance criteria, ship a handover, then decide. Fixed scope beats open-ended transformation.
5 min readAgent demos hide the hard parts.
Tools, permissions, loops, observability, and stop conditions are the product. Demos skip them.
5 min readLocal models when data cannot leave.
On-prem and local inference make sense under hard data constraints. Capability and ops cost are the tradeoff.
5 min readThe cost of retries and review.
Total cost is inference plus retries plus human review plus delay. A cheap model can still be expensive.
5 min read88% use AI. Few have scaled it.
McKinsey’s November 2025 survey: adoption is common, enterprise EBIT impact is not, and agents are rarely scaled.
6 min readShadow AI needs a lighter governance model.
Approved tools, data classes, review for external actions, and logging beat a policy nobody follows.
5 min readOnly 5% get AI value at scale.
BCG’s 2025 Widening AI Value Gap: n>1,250 companies, a thin top tier, and a large stuck middle.
4 min readRAG fails when retrieval is wrong.
Evaluate the retriever first: citations, golden questions, permissions, and stale documents.
4 min readHackerOne’s scheduling automation ROI.
Public Calendly story: 169% ROI, 588 hours saved, more meetings and customers—with SSO/SCIM constraints.
4 min readKeep a person in the loop.
HITL patterns that actually ship: draft vs send, prepare vs execute, confidence with sources, clear escalation.
3 min readRebrandly cut support tickets in half.
A public Zapier story: docs-grounded chat, Slack+Jira escalation, and 16,000+ resolved conversations.
4 min readAI Index 2025: what businesses should notice.
Adoption and investment jumped. Reported functional cost savings often stayed under 10%.
4 min readWhen not to use AI.
Four plain conditions where a model adds cost, risk, or noise instead of leverage.
3 min readInference costs fell more than 280×.
Stanford’s AI Index 2025 puts a hard number on how fast GPT-3.5-level performance got cheap.
4 min readLitmus consolidated support. Retention rose.
Public Help Scout case study: Litmus moved off split Intercom + WordPress tooling; early support interaction tied to 26% higher retention.
5 min readOne workflow. Then a platform.
A shared AI platform designed before a real workflow exists usually standardizes the wrong things.
4 min readGen AI use doubled. EBIT impact stayed rare.
McKinsey: regular gen AI use hit 65% in early 2024. Later survey work still finds most firms report no tangible enterprise EBIT from it.
5 min readThe prototype is not the product.
A convincing demo is not a system people can depend on. Product work starts when inputs stop being carefully chosen.
4 min readLab speed is not field pull requests.
A controlled Copilot task was 55.8% faster. Field experiments at Microsoft and Accenture show smaller, noisier PR gains.
6 min readSupport assistants raised resolution 14%.
NBER evidence from 5,179 agents: generative AI guidance lifted issues resolved per hour—especially for novices.
5 min readMeasure the work. Not the tokens.
Token price is easy to compare. Cost per accepted task is what decides whether a model choice is cheap or expensive.
4 min readMost AI pilots stall before value.
BCG finds only 4% of companies create substantial AI value. Nearly half are still stuck in proofs of concept.
