Describe the scope of work in detail. Please include a summary of key deliverables.
Coretus Technologies undertook a deep, end-to-end audit of our AI stack and delivered a comprehensive solution. The scope included: Comprehensive AI Audit & Strategy: They began with a full assessment of our existing data pipelines, model architectures, and training datasets, providing a strategic roadmap for improvement. Data Pipeline Optimization: They re-engineered our data ingestion and preprocessing pipeline using Apache Kafka and Apache Spark, enabling real-time feature engineering and handling a 300% increase in data throughput. Advanced Model Development & Retraining: This was the core of the project. They developed and implemented a new ensemble model architecture, combining a fine-tuned Transformer network for analyzing behavioral sequences with a Graph Neural Network (GNN) to map relationships between seemingly unrelated security events. MLOps Infrastructure: They built a robust MLOps pipeline on Kubernetes, automating model training, versioning, testing, and deployment. This allowed us to safely roll out and roll back model updates. Real-Time Inference Engine: They delivered a high-performance, containerized inference engine that integrated seamlessly with our existing API, slashing our response times. Predictive Threat Dashboard: A custom internal dashboard was developed that visualizes threat clusters and predicts emerging risks using the new model's outputs, giving our analysts a significant advantage.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The results fundamentally strengthened our product's market position:
42% Reduction in False Positives: This was a game-changer for our clients, drastically reducing alert fatigue for their security teams and increasing trust in our platform.
15% Increase in True Positive Detection: Our ability to identify genuine, sophisticated threats saw a significant jump, directly enhancing our clients' security posture.
Sub-80ms Average Inference Time: They far exceeded our latency target, enabling true real-time threat prevention that our customers can rely on.
A 5x Increase in Data Processing Capacity: The new scalable infrastructure future-proofed our platform, allowing us to onboard large enterprise clients without performance degradation.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
They used a clear, milestone-driven approach with bi-weekly sprint reviews and transparent risk registers.
Timeliness: Coretus Technologies delivered all major milestones on or before schedule. The project was completed within the original 6-month timeframe, a rarity for complex AI initiatives.
Responsiveness: They were not just contractors; they were integrated team members. When we discovered a new, novel attack vector mid-project, they immediately pivoted a sprint to incorporate this data into the model retraining cycle, demonstrating incredible agility and commitment to our shared success.
What was your primary form of communication with Coretus Technologies?
Virtual Meeting
Email or Messaging App
What did you find most impressive or unique about this company?
Their profound, foundational knowledge of both AI theory and production-grade engineering was the most remarkable feature. While many consultants are capable of creating a precise model in a lab, Coretus Technologies creates models that are accurate, scalable, and maintainable in a real-world, hostile setting. Our team is able to make better decisions because of their ability to communicate intricate model behaviors and architectural trade-offs in business terms.
Are there any areas for improvement or something Coretus Technologies could have done differently?
Given how successful the engagement was, this is a challenging question. If I were to make one helpful recommendation, it would be to include even more thorough documentation in the early stages of knowledge transmission. Even though the final documentation was great, our internal team's onboarding process may have been sped up if we had had access to somewhat more detailed, intermediate architecture diagrams sooner. This was a small detail in an overall excellent execution, though, and they were quite quick to respond to our requests for information.

OPPORTUNITY / CHALLENGE
What specific goals or objectives did you hire Coretus Technologies to accomplish?

Describe the scope of work in detail. Please include a summary of key deliverables.
Coretus Technologies delivered a custom-built, headless e-commerce solution that was a work of art in functionality. The scope was extensive and meticulously planned: A Bespoke Front-End Experience: They built a stunning, responsive front-end using a modern framework that allowed for the complex animations and interactive elements we designed. This included a "Canvas" feature on product pages where users could dynamically change the background to see how our art prints would look in different virtual settings. Automated Digital Delivery Gateway: They developed a secure, automated system for digital products. Upon purchase, customers instantly gain access to a personalized, brand-aligned download portal with a license certificate, creating a sense of value and exclusivity. Advanced Product Filtering & Storytelling: They implemented a powerful filtering system that allowed customers to shop not just by product type, but by "collection" and "inspiration," weaving a narrative around our merchandise. CMS & Inventory Integration: A fully custom admin panel was built, giving our non-technical staff the ability to manage complex inventory, create flash sales, and write long-form editorial content to accompany product launches.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The new site has become our single most effective new business and talent acquisition tool. We have seen a substantial increase in the average order value, particularly for our high-margin art prints and digital toolkits. The most telling success metric is the feedback we receive; we consistently have clients and job applicants mention the experience of browsing our store as a key reason they reached out. The platform handled the launch of our "Chicago Design Week" limited collection without a single glitch, processing a surge of orders that would have crippled our old system. The number of customer service tickets related to digital download issues has dropped to nearly zero.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
The project management was a masterclass in collaboration. We worked with a dedicated Coretus project lead who facilitated weekly "creative sync" meetings that were as much about brand philosophy as they were about task completion. There was one pivotal moment during user testing when we realized our beautifully complex add-to-cart animation was causing confusion for a subset of users. Instead of defending their code, the Coretus team scheduled an emergency whiteboarding session. Within 48 hours, they had prototyped three alternative, more accessible micro-interactions for us to choose from. They delivered the final, refined solution ahead of the revised schedule. They don't just meet deadlines; they respect our creative process and problem-solve with us in real-time.
What was your primary form of communication with Coretus Technologies?
Virtual Meeting
Email or Messaging App
What did you find most impressive or unique about this company?
They didn't see our ambitious design specs as obstacles; they saw them as creative challenges to be solved. I was personally blown away when, during a technical review, their lead developer paused the meeting to point out a subtle typographic alignment issue on a mockup that even our junior designer had missed. He explained, "If this is about embodying your brand, the kerning on this headline isn't right." The fact that a backend engineer was advocating for pixel-perfect typography demonstrated a level of holistic investment we have never experienced with a technology partner. They became true comrades in our mission.
Are there any areas for improvement or something Coretus Technologies could have done differently?

BACKGROUND
Introduce your business and what you do there.
I'm the founder and CEO of an AI-powered SaaS provider offering solutions like chatbots, HR, and finance tools to help businesses automate operations, enhance efficiency, and drive growth through AI.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Coretus Technologies?
We needed to partner with an expert team to build our core enterprise-grade SaaS platform from the ground up. We needed a partner who could handle the entire product lifecycle, from architecture to launch.
SOLUTION
What was the scope of their involvement?
Coretus Technologies handled the full end-to-end scope of our project. They were our sole technical partner, taking us from a high-level concept to a fully operational, enterprise-grade SaaS platform.The scope of work included:1. Discovery & Architecture: Running initial discovery workshops to define the product roadmap and technical requirements.

This included CI/CD pipelines, monitoring (Prometheus/Grafana), and Infrastructure as Code (Terraform) for a secure, scalable, and SOC2-ready setup.
What is the team composition?
We worked with 10 teammates from Coretus Technologies.
How did you come to work with Coretus Technologies?
We found them through a referral. We chose them over other options because they had high ratings, their pricing fit our budget, they offered good value for the cost, and their company values aligned with ours.
How much have you invested with them?
We spent $250,000.
What is the status of this engagement?
We worked together from May 2023–August 2025.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
The most measurable outcome was that Coretus Technologies delivered our entire complex multi-tenant platform on time and on budget, exactly as promised. Since launching, the system has been rock-solid, maintaining over 99.9% uptime. Critically, all the AI and automation features they built were fully functional from day one, successfully automating the key business workflows we had targeted.The impact was immediate. In terms of process improvement, our team's lead time for key tasks was reduced by over 40% due to the new automated workflows Coretus Technologies built. This translated directly into cost savings, as we were able to reallocate two full-time employees from manual data entry to higher-value client-facing roles.We also saw high user adoption, with over 90% of our team actively using the platform daily within the first month. Most importantly, the platform's stability has been perfect, maintaining 100% uptime during our peak business hours, which was a major problem with our old system.
How did Coretus Technologies perform from a project management standpoint?
Coretus Technologies' project management was excellent and a key reason our project succeeded. The entire process was transparent and proactive, with weekly live demos and daily access to their team on Slack. They handled all the complexity, and we were never in the dark.Moreover, they absolutely delivered on time. They gave us a clear timeline from the start, and they hit every single milestone punctually, including delivering our MVP in just four weeks. Even when we faced unexpected third-party challenges, they managed it without any delays to our final launch.As for communication, we used in-person meetings, virtual meetings, and emails or messaging apps. Even when we faced unexpected third-party issues, they managed it perfectly and delivered the final project exactly on time. The value we got—in terms of speed, quality, and 100% IP ownership—was outstanding.
What did you find most impressive about them?
What's truly unique about Coretus Technologies is the combination of their deep, expert-level technical skill with genuine, transparent partnership.Many firms can build software, but Coretus Technologies brought elite-level expertise in both complex AI/automation and enterprise-grade cloud architecture (Kubernetes). They didn't just understand our advanced vision; they had the rare technical ability actually to build it, and build it right.But the most impressive part was their process. Their commitment to weekly demos with tangible, working code isn't just a sales pitch; it's a guarantee. It completely de-risked the entire project, built incredible trust, and made them feel like a dedicated part of our own team, not just a vendor.
Are there any areas they could improve?
Honestly, it's very difficult to find anything to critique. The entire project was managed exceptionally well, and the team's expertise was clear from day one.If I had to name one thing, it's that I wish we had engaged them for even more of the initial product strategy. Their technical and business insights during development were so strong that we realized later we could have saved even more time by bringing them in even earlier—before we had finalized our own specifications. It's not a fault of theirs, but a realization of the value they bring beyond just coding.
Do you have any advice for potential customers?
Engage them as early as possible. The quality of both their technical work and their client service is outstanding. Their team combines elite technical expertise in AI and cloud architecture with flawless, transparent project management. They delivered our complex platform on-time and on-budget, exceeding every goal. We give them our highest possible recommendation. They are a true strategic partner.

OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Coretus Technologies?
We needed support to develop a fast, market-ready MVP of our AI-powered meal planner and health assistant on iOS.
SOLUTION
What was the scope of their involvement?
Coretus Technologies provided end-to-end design and development for our iOS app. The team was responsible for the following tasks: - Discovery and architecture: business goals, user journeys, data model, and scalable cloud setup with CI/CD - UX/UI: brand-aligned Figma designs, design system, and responsive layouts - Catalog and search: product taxonomy, variants/attributes, filters, AI-assisted search, and recommendations - Cart and checkout: guest/login flows, address book, coupons, gift cards, taxes, shipping rates, and order confirmations - Payments: Stripe/PayPal with Apple/Google Pay, SCA/3-D Secure, refunds/partial refunds; PCI handled via hosted fields/tokens - Subscriptions and promotions: memberships, bundles, scheduled deliveries, discount rules, and upsell/cross-sell - Order and inventory management: statuses, cancellations/returns (RMA), stock sync, and low-stock alerts - CMS and content: landing pages, product storytelling, FAQs, and SEO best practices (meta, schema, sitemaps) - Notifications: email/SMS/push for cart recovery, shipping updates, and lifecycle events - Analytics and observability: event tracking for funnel/retention, dashboards, crash/error monitoring - Security and compliance: role-based access, audit logs, GDPR-ready privacy controls

How did you come to work with Coretus Technologies?
We found Coretus Technologies through an online search. Their portfolio and expertise immediately stood out, and after a detailed discussion, we decided they were the right fit for building our application.
Coretus Technologies stood out for two reasons: real AI depth and speed to value. The team showed a clear plan to power EAT with AI—LLM-driven personalization, recipe recommendations, and a sensible MLOps path with security and data privacy baked in. Coretus Technologies is also committed to a four-week MVP with weekly demos, realistic milestones, and 100% code/IP ownership. Their proposal was the most rigorous, and their communication was the fastest, so choosing them over others was straightforward.
What is the status of this engagement?
We worked together from July 2024 –June 2025.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
In the first 60–90 days post-launch, we saw clear wins across speed, quality, adoption, and revenue:
MVP shipped to TestFlight in four weeks and went live on the App Store in week six, hitting all milestones on time
99.6% crash-free sessions (Firebase Crashlytics) and median app launch time ~1.2 seconds; p95 <2.5 seconds
61% activation rate (completed onboarding + first meal plan), with 28% 30-day retention; DAU/MAU ~19% (GA4)
Engagement: 72% of active users use the weekly planner; recipe saves per user up 38%; 42% export grocery lists weekly
Monetization: 11.3% trial-start rate and 5.1% paywall-to-paid conversion in the first 30 days (App Store Connect)
After an AI-tuning update (version 1.1), plan adherence improved 22%, and LTV projections rose ~18%
We defined success upfront and instrumented GA4 (events/corts), Firebase Crashlytics (quality/performance), and App Store Connect (subs/revenue).
For activation, we measured the rate of users who completed onboarding and created their first meal plan within seven days of installing the app. Secondary signals were the first grocery list exported or three recipe saves in seven days.
For retention, we measured the 1, 7, and 30-day retention rates. For stickiness, we measured the DAU/MAU ratio for the last 30 days.
For engagement, we measured the percentage of weekly active users using the weekly planner, exporting grocery lists, and saving recipes. We also measured the median sessions per user per week, median session length, recipe saves per active user, and plans created per week. As a proxy for outcomes, we measured the plan adherence rate, which is the number of planned meals marked completed divided by the total planned meals. For AI quality, we measured the recommendation acceptance rate, overrides per plan, and time to the first AI plan.
For quality and performance, we measured crash-free sessions, ANR rate (Crashlytics), cold-start, and p95 screen render times (Firebase Performance).
For monetization, we measured the trial start rate and trial-to-paid conversion rate. We also monitored the refund rate and churn (App Store Connect).
All metrics were shown on GA4 dashboards with weekly cort cuts and a 30-day rolling view so we could see activation improvements and retention/engagement lift after each release.
How did Coretus Technologies perform from a project management standpoint?
Coretus Technologies ran the project with tight, transparent Agile execution and delivered exactly on time. We had a clear roadmap, weekly sprints with demo calls, and a shared ClickUp/Jira board for milestones and dependencies. Communication was proactive — Slack updates daily, quick decisions, and written release notes for every build. The team hit every date: MVP to TestFlight in four weeks and public App Store launch in week six, with zero schedule slippage. Change requests were handled through impact notes, so scope stayed controlled without surprises. Overall, the team had disciplined project management, fast responses, and on-time delivery.
What did you find most impressive about them?
Two things stood out above everything else: Coretus Technologies' real AI depth and their founder-level product ownership. The team didn't just add AI; they designed an LLM-driven personalization engine, set up a sensible MLOps path, and baked privacy/security into every decision.
Equally impressive was the speed with predictability — an investor-ready MVP in four weeks with weekly demos, zero schedule slip, and 100% code/IP ownership. Coretus Technologies behaved like co-founders, not vendors: they challenged our assumptions, translated goals into measurable KPIs (activation, retention, LTV), instrumented analytics from day one, and iterated quickly based on data. Handoffs were clean (docs, infra-as-code, test suites), communication was proactive, and the UI/UX quality matched the engineering. That combination of AI expertise, product thinking, and on-time execution was what made them unique.
Are there any areas they could improve?
The project exceeded expectations. If I had to suggest something, I'd start Android parity a sprint or two earlier to avoid a platform gap, schedule a couple more mid-sprint usability tests to catch small UX polish sooner, and provide even more step-by-step runbooks (admin, monitoring, experiment setup). These are nice-to-haves only — the delivery quality and results were excellent.

Our Story
Founded in 2013, Coretus began with a simple mission: to bring Fortune 500 engineering rigor to ambitious product builds. We aren't just coders; we are product partners. Our vision is to eliminate the trade-off between speed and stability. By productizing complex architectures (Microservices, AI Agents), we empower US & EU enterprises to launch scalable, IP-owned platforms in weeks, not months. We value transparency, 100% ownership, and engineering that survives first contact with scale.
What Sets Us Apart
Business-First Engineering
We don't just clear JIRA tickets; we build business assets. Every line of code is written with future scalability and maintenance in mind (Clean Architecture).
Transparent Velocity
We provide direct access to engineers via Slack/Teams and hold daily standups in US/EU time zones. No account managers hiding the reality of the project.
100% IP Ownership
Unlike many agencies, we transfer all Intellectual Property (Code, Designs, Assets) to you immediately. You are never locked in.
