AI velocity without
the risk.
We build the verification layer that lets engineering teams adopt AI coding tools with confidence — catching risky changes, guiding reviewers, and enforcing policy before code hits production.
The Problem
AI is accelerating code creation. Nothing is accelerating verification.
The Velocity Paradox
Teams ship faster with AI coding tools, but PRs get larger, noisier, and harder to review. Senior engineers become the bottleneck.
Hidden Risk
AI-assisted changes introduce subtle security, reliability, and maintainability issues that existing scanners miss because they lack workflow context.
Trust Gap
Leadership pushes AI adoption. Nobody wants to own the downside. Teams move fast but trust the code less.
Our Approach
Merge confidence, not just merge speed.
Pullminder is not another AI code review tool. We are an infrastructure-grade verification layer — a workflow-aware system that scores risk, guides reviewers, and enforces merge policy tailored specifically to AI-generated code.
- Risk ScoringEvery PR gets a risk level based on diff size, sensitive directories, test coverage, and security patterns.
- Reviewer GuidanceAutomated reviewer briefs highlight what to verify manually — not generic summaries, but verification-focused guidance.
- Policy EnforcementOrg-level rules that detect secrets, missing tests, insecure patterns, and prohibited changes before merge.
MISSION Make AI-assisted coding safe at scale
FOCUS Verification, not generation
TARGET B2B SaaS · 20-150 engineers
METHOD Risk scoring + policy enforcement
✓ Merge with confidence.
Principles
What drives us
Consistency
Risk scoring and policy checks produce consistent, repeatable results. AI briefs augment — they don't replace deterministic analysis.
Minimal Exposure
We process only diff hunks from changed files — never full source code. AI briefs are opt-in. Your data stays within clear jurisdictional boundaries.
Human-First
We augment reviewers, not replace them. The goal is to free senior engineers for high-level design work.
Outcomes
We measure value in risky PRs caught and reviewer hours saved — not tokens consumed.
Who We Are
Built by practitioners, not theorists.
Pullminder is built by Upmate — a digital consulting and engineering agency founded in 2004 in Thessaloniki, Greece. For over two decades, we have worked at the intersection of strategy, technology, and commerce, serving clients across Greece, Cyprus, and the EU.
We are not a VC-funded startup chasing growth at all costs. We are a self-funded, profitable engineering team that builds products we would use ourselves. Pullminder exists because we saw the AI code review problem firsthand in our own development workflow — and built the tool we needed.

Christos Varytimidis
Founder & CEO
Over 20 years leading digital commerce and growth strategy. Christos thinks in systems — how technology, data, and business strategy connect into outcomes that compound over time. He led a decade-long engagement that grew a client from 9,000 to 100,000+ customers through sustained strategic iteration.
Ioannis Karasavvaidis
Co-Founder & CTO
The technical foundation behind every product Upmate ships. Ioannis architects complex platforms, API integrations, and AI-powered applications with the same discipline: understand the problem first, then engineer a solution that is robust, maintainable, and built to scale — not just to ship.
“Strategy before technology. Every time.”
— The operating principle behind every Upmate engagement since 2004
Why It Matters
Your code pipeline is too important for anonymous tooling.
When you install a verification layer into your CI/CD pipeline, you need to know who built it, how they think about security, and whether they will still be around next year. Here is what sets us apart:
Self-Funded & Profitable
No VC pressure to monetise your data or pivot. We build for longevity, not a liquidity event.
EU-Based Engineering
Headquartered in Thessaloniki, Greece. GDPR-native. Your data stays within clear jurisdictional boundaries.
20-Year Track Record
We have been building production systems since 2004. Pullminder is not our first product — it is the latest in a line of battle-tested platforms.
Built For
Engineering teams that refuse to choose between speed and safety
Pullminder is purpose-built for B2B SaaS companies with 20–150 engineers who are already using AI coding tools and starting to feel the second-order effects.
Wants AI productivity without increasing incident risk
Needs policy enforcement without manually inspecting every AI-assisted PR
Wants to focus on risky changes first, not wade through AI-generated noise
