VP of Engineering
David writes about engineering culture, team building, and leadership — the human side of building technology companies. With experience leading engineering at both remote-first and hybrid organizations, he brings a practical perspective on how to attract, retain, and develop top engineering talent. His writing on 1-on-1 meetings, remote management, and career frameworks has been shared by thousands of engineering leaders.
LLMs moved decision-making into tools. If leaders don’t own the model layer—prompts, policies, and audit trails—culture becomes a black box and incidents become inevitable.
Founders keep treating fine-tuning as a product strategy. In 2026, the winners ship model-agnostic systems: retrieval you can audit, routing you can change, and contracts you can test.
By 2026, startups aren’t choosing a model—they’re inheriting a vendor maze. Here’s how to build an AI stack that won’t trap your product, margins, or roadmap.
The agent era isn’t a productivity hack. It breaks code review, CI, and ownership unless you rebuild the pipeline around specs, policies, and reproducible runs.
RAG demos still sell, but 2026 winners treat evaluation, provenance, and access control as the core system—not the model choice.
2026 product teams are done with demos. The winners are packaging agents as constrained workflows with auditable permissions, not free-form chat.
The winners won’t be the loudest copilots. They’ll be the teams that own identity, policy, audit, and cost control across models, tools, and data.
Agents fail in boring ways: stale context, untested changes, and overbroad permissions. The 2026 stack fixes that with MCP, eval gates, and tight blast-radius controls.
Most agent failures aren’t “hallucinations.” They’re tool errors, runaway loops, permission mistakes, and unbounded spend. Here’s the production playbook that fixes those.
The agent demo isn’t the product. The product is budgets, permissions, traces, and rollback—so customers can let automation run without babysitting it.
If your “agent” can’t explain every tool call, cap spend per task, and fail safely, you didn’t ship a product—you shipped a demo.
AI tools are everywhere. What’s rare is leadership that can let agents move fast without shipping nonsense, leaking data, or lighting money on fire.
If your pitch is “we use the best model,” you’re already losing. In 2026, defensibility comes from workflow control, rights to feedback data, and distribution.
Inference spend doesn’t scale like web requests. Treat AI features like real-time systems—budgeted, routed, traced—or your margins and SLOs collapse.
Agent demos are cheap. Operating agents inside real systems of record isn’t. Ship one workflow with constraints, verification, and audit trails—or don’t ship it.
Training is a project. Inference is rent. Here’s what operators change—routing, caching, batching, token budgets, and GPU utilization—so costs drop without wrecking UX.
The hard part of agents isn’t tool wiring—it’s stopping bad actions, proving what happened, and keeping costs sane. Here’s the stack serious teams are standardizing on.
Agents don’t fail like APIs—they “complete” the task while quietly doing the wrong thing. Here’s the 2026 reliability stack teams use to keep autonomy safe, cheap, and reviewable.
Cool agent demos don’t pass security review. The 2026 winners ship audit trails, policy gates, and evals that survive model swaps and real permissions.
A chatbot is a feature. An agent that moves work across systems—measured, traced, and permissioned—is the product. Here’s the 2026 stack and rollout.
Agents can open PRs, change configs, and message customers. Leadership in 2026 is building boundaries, evals, and audit trails so speed doesn’t turn into incidents.
Agents don’t fail like APIs—they take actions. Build them like operators: scoped identity, safe tools, deterministic guardrails, and traces you can replay.
Static pipelines fail once LLMs can act. The teams pulling ahead treat traces, evals, and tool permissions as production systems—and ship changes behind gates.
Chat demos don’t survive procurement. In 2026, the durable AI products are workflows with clear boundaries, observable behavior, and action you can approve—or undo.
Agents don’t “answer.” They execute. That turns AI into a cost center, an identity problem, and an uptime problem—unless you build a real platform around it.
Remote teams don’t fail from distance. They fail because decisions vanish into chat. Build culture by making work legible: written decisions, real docs, and deliberate rituals.
