Intelligent tools and guidance for the businesses building what's next.
Sternmark LLC is a two-practice studio. We ship Growth Guardian, an AI-powered online reputation platform for SMBs — and we partner directly with organizations ready to move from manual systems into AI that is meaningful, efficient, proven, and safe.
Pick the one that fits where you are today.
Sternmark clients often start with one practice and grow into the other. The software pays for itself; the advisory re-draws the map.
Meet Growth Guardian.
Online reputation management, built for the businesses that actually need it.
Our flagship SaaS product. Review monitoring, smart response drafting, sentiment analysis, and competitive benchmarking — all in one place, at a fraction of what the big players charge.
Review Management
Monitor, respond to, and learn from every review across every platform — before the narrative gets written for you.
AI-Powered Insights
Surface patterns, flag emerging issues, understand what customers really mean — not just what they say.
Built for SMBs
Enterprise-grade capabilities at independent-business prices. No long contracts, no per-location traps.
Want early access or to be a pilot partner? We're onboarding a small cohort of local-service businesses, restaurants, and multi-location brands to shape the v1 product.
Sternmark Advisory: AI integration, done properly.
A bespoke consulting practice for organizations shifting from manual, spreadsheet-stitched systems into AI-native operations. We sit with your team, map the work as it actually happens, and build systems that are proven before they go live.
Proven. Safe.
Meaningful
We refuse to bolt AI onto problems humans are already solving well. We only deploy where it moves a real number — revenue, hours saved, defect rate, customer hold time.
Efficient
Small, sharp systems beat sprawling stacks. We ship automations that replace concrete manual hours first, then compound.
Proven
Every system ships with evaluation harnesses, rollback paths, and live quality dashboards. If it regresses, you'll know before your customers do.
Safe
Data boundaries, access reviews, prompt-injection hardening, PII handling, and audit logs — baked in from day one, not bolted on after an incident.
Three ways to work together.
AI Opportunity Audit
A deep audit of your current operations. We find where AI will actually pay for itself — and where it won't. You leave with a ranked roadmap, ROI modeling, and a shortlist of quick wins.
- Process & tooling interviews
- Opportunity map + ROI estimates
- Risk & compliance review
- 90-day quick-win plan
Workflow Integration Sprints
We replace specific manual workflows with AI systems that genuinely work — ingestion, drafting, classification, QA. Built on proven platforms, with your team trained to own them.
- Agent & automation design
- Safe-deploy rollouts with eval gates
- Handoff docs, dashboards, runbooks
- 30-day post-launch support
Fractional AI Advisor
Monthly engagement for orgs that need senior AI judgment on call — vendor selection, policy review, model updates, leadership sessions, the stuff that can't be a one-off project.
- Biweekly working sessions
- Policy & governance reviews
- Vendor & model diligence
- Team office hours
A process built around proof, not hype.
Most AI initiatives fail for the same reason — someone bought the technology before anyone understood the workflow. We reverse it. Observation first, architecture second, code last, ownership always with you.
- Full source, full data, full docs
- Runbooks your team can operate
- Eval suites to prove it stays working
Listen
We sit with your team. Shadow shifts. Read the tickets. Map the way work actually moves — not the way the org chart says it does.
Map
We score every candidate workflow on impact × feasibility × risk, and write the plan in plain English. You approve before anything gets built.
Build
Short sprints. Working software in front of real users in weeks, not quarters. Every agent, eval, and guardrail is documented.
Measure
Dashboards show real outcomes — hours saved, quality held, escalations handled. If the numbers don't move, we stop.
Handoff
Your team owns the system end-to-end. Runbooks, training, and a 30-day support window so the knowledge stays in-house.
We're probably a fit if…
- You have teams still doing pattern-matching work by hand.
- You tried an AI pilot and it fizzled — or worse, broke trust.
- You're worried AI will be deployed badly before it's deployed well.
- You need someone senior in the room who isn't selling a platform.
Fit sessions are 30 minutes, no pitch deck. If we're not the right team, we'll say so — and point you somewhere better.
Book a scoping callThe company behind the guardian.
Sternmark LLC is a California-based technology studio founded by Jonah in 2026. We build focused, intelligent tools — and we partner directly with the teams ready to modernize how they work.
We're deliberately small. Two practices, one team, every engagement touched by senior hands. We'd rather do ten things that actually move the needle than a hundred that look good in a deck.
Small business first
Every product decision, every engagement price, every recommendation is sized for the businesses that can't afford to get it wrong.
Simplicity over sophistication
If a spreadsheet would solve it, we ship a spreadsheet. We only reach for AI when it's genuinely the right tool.
Safety before speed
No AI deployment ships without evals, rollback, and a human-in-the-loop plan. Trust is the expensive asset.
Transparent always
Honest pricing, honest scope, honest postmortems. No black-box fees, no retainer creep, no mystery dashboards.
