We cannot live without you guys. I don't even consider you guys as an agency. I almost consider you guys as a fractional CTO. You guys delivered in a week what I tried to build in four months with another company. You're saving us probably $5,000+ a month just in tools alone.

Who Is This For?

Agencies

Revenue-generating agencies who have tried to build their operational system and either failed or are almost there and don't know how to make it better.

GTM Teams

In-house revenue and GTM teams who have outgrown their tools and need production-grade infrastructure without hiring an entire engineering department.

Sound Familiar?

You've Tried to Solve This Before.

01

Data Chaos

You Don’t Trust Your Own Numbers.

Your data lives in 6 different tools. Reports take hours to pull and still don’t match because every tool has already aggregated the numbers its own way. You never see the raw truth.

✕ Which is right?

Felix Frank

We were having recurring issues with data accuracy. Moving to the custom app and backend you guys built has really unlocked improved efficiency.

Felix Frank, Founder, Stack Optimize

Foundation

One Source of Truth

Each tool keeps its own version of your numbers. That’s why reports never match. The missing piece was never another app. It was the layer underneath that makes them work as one. We build that layer.

Scale Failure

Your Tools Break When You Scale.

You have vibe coded your ops into existence. It worked on smaller scale. Now you’re hitting row limits, broken syncs, and duct-taped workarounds everywhere.

Operational Infrastructure

Built to Scale

No-code tools got you here. But they were never meant to be your backend. We build production software underneath your operations. Monitoring, alerting, failure recovery. Your team stops firefighting.

Silent Decay

Your System Kind of Works. That’s the Problem.

Dashboards are populated. Numbers come back. But half your integrations broke weeks ago and nobody noticed. 95% accurate - just wrong enough to make every decision built on it a guess.

Data Integrity

Nothing Breaks Silently

APIs change. Schemas drift. Syncs go stale. Nobody notices for weeks. We build monitoring into every layer. Schema validation on ingestion. Automated alerts when patterns shift. Your system watches itself.

AI Blindness

You’re Falling Behind on AI. And You Know It.

The output of AI is only as good as the input you feed it. You’re not behind because of effort. You’re behind because of infrastructure.

Why Stimuli

Compare Your Options.

Built by engineers with your domain knowledge?

Stimuli

Helped 40+ agencies and GTM teams build the system you’re trying to build.

Dev Agency

They learn your industry on your dime. Every engagement starts from zero.

In-House

Every mistake we’ve already made and fixed, you’ll discover the hard way.

Own the systems & data you pay for?

Stimuli

Fully yours. Open tech, documented from day 1.

Dev Agency

Usually yours, but domain-ignorant code you can’t maintain.

In-House

Yours, but undocumented and held together by whoever built it.

Result in week 1?

Stimuli

Impact before the first invoice. That’s the standard.

Dev Agency

Weeks of scoping calls. Months of ‘alignment’. Maybe something ships in Q2.

In-House

Hiring alone takes longer than our first 3 sprints.

Production-grade infrastructure?

Stimuli

Designed by a solutions architect, built by olympiad medalists. Monitored and battle-tested across 40+ deployments.

Dev Agency

Ships on deadline, breaks on launch. Maintenance is a separate contract.

In-House

One person building, monitoring, and firefighting. Until they burn out.

Fractional team, fraction of the cost?

Stimuli

Architect + engineers + domain expertise. €8-12K/mo.

Dev Agency

€150K+ project fee. And that’s before change requests.

In-House

€200K+/yr salary, plus tools, plus management overhead, plus turnover risk.

Handle 3x growth without rebuilding?

Stimuli

Architected to grow with you. No rewrites, no migrations, no ceilings.

Dev Agency

They build what you asked for today. Tomorrow’s scale is a new project.

In-House

Depends entirely on who you hire.

Questions You Might Have

Infrastructure is a living system. APIs change, data volumes grow, business rules evolve. Every one-time build we’ve inherited started as someone’s “finished” project. Our sprint model means you get something shipped every week, and the system keeps evolving with your business.

We start with a diagnostic sprint. We audit your stack, map every data flow, and deliver a concrete plan. From there, two tracks run simultaneously: Track 1 fixes the fires hurting you right now. Track 2 architects the long-term system underneath. You see quick wins in the first weeks while the real infrastructure takes shape.

Week 1. The diagnostic sprint alone produces an architecture document and prioritized roadmap. Most clients have their first workflow fixed or automated within the first two sprints. The full system typically takes 8–12 weeks to build, but you’re getting value from sprint one.

AI can build you a demo in an afternoon. Making it work in production — with real data, real edge cases, and real scale — takes domain knowledge that only comes from doing this 40+ times. We use AI every day. It makes us faster. But it doesn’t replace knowing what to build.

They could write the code. But building data infrastructure that works at scale requires pattern recognition from doing it dozens of times. Every edge case your team would discover the hard way, we’ve already solved and documented.

That was domain ignorance, not dev incompetence. Generic agencies learn your industry on your dime and can’t catch incomplete specs. We started as operators building these systems for our own business. We don’t need a discovery phase to understand your stack.

A freelancer is one person with one skill set. We’re a full team: solutions architect, engineers, and domain specialists working in weekly sprints. When a freelancer leaves, the knowledge leaves with them. With us, everything is documented, the code is clean, and the system doesn’t depend on any single person.

We’re tool-agnostic. HubSpot, Salesforce, Pipedrive, Google Ads, LinkedIn Ads, Stripe, custom databases — we integrate whatever your stack runs on. We build on open technologies (Postgres, REST APIs, mainstream frameworks) so you’re never locked into proprietary tools.

We don’t replace anything. Your CRM, ad platforms, and billing tools stay exactly where they are. We connect them, clean the data flowing between them, and build the infrastructure that makes everything work as one system. No migrations, no retraining your team.

You get the architecture document, gap analysis, and prioritized roadmap. If it makes sense for both sides, we move into the monthly retainer and start executing from sprint one. If not, you walk away with a complete technical blueprint you can hand to any team. The diagnostic is credited toward your first month if you continue.

The diagnostic sprint is designed to prove it before you commit. For €1.5K you get a full audit and roadmap in one week. If the results don’t convince you, you keep the deliverables and walk away. Every client so far has continued.

Your data stays in your infrastructure. We work within your existing cloud environment and access controls. We don’t store, export, or retain any of your data outside your systems.

We’re all in one office in Tbilisi, Georgia. No remote contractors, no distributed teams. We work in the same room, communicate via Slack with clients, and overlap with EU and US timezones.

Start With a Diagnostic Sprint.

One week. One audit. A complete roadmap for your infrastructure. If it makes sense, we keep building.
