Greybox Consulting Limited — Mombasa, Kenya

Coastal data
is fragmented.
We fix that.

Government agencies, marine NGOs, and fishing communities generate rich data — but it sits in silos, unusable and invisible. We build the systems that connect it.

The Problem

Data that could drive decisions
sits idle in the wrong hands

Coastal communities, fisheries departments, and conservation NGOs across East Africa face a common set of interconnected challenges.

🗂️

Fragmented Data Silos

Catch registers, BMU governance records, socioeconomic surveys, and spatial datasets live in incompatible formats across dozens of institutions — impossible to query together.

🌊

No Real-Time Visibility

Fisheries managers make decisions without access to current data. By the time reports are compiled, the situation on the water has changed significantly.

📉

Weak Monitoring Systems

Donor-funded projects require rigorous M&E, but field teams still rely on paper forms and spreadsheets. Reporting is slow, inconsistent, and prone to error.

🧭

GIS Capacity Gaps

Critical decisions about fishing grounds, mangrove boundaries, and marine protected areas are made without proper spatial data — because the maps don't exist.

💸

Community Groups Excluded

Women's savings groups, Beach Management Units, and self-help groups lack digital tools for accounting, loan tracking, and business management.

🔒

Systems Built Once, Then Abandoned

Many organizations have invested in ICT systems that were never maintained, trained-for, or integrated — creating expensive technical debt with no lasting value.

Domain expertise meets
engineering discipline

We are not a generic IT firm. Our consultants have worked directly inside coastal and marine programmes for over a decade.

BUILT FOR YOUR CONTEXT

We understand BMU governance, EBM frameworks, KoBoCollect workflows, and donor reporting requirements — because we've worked inside them.

FULL-STACK DELIVERY

From requirements gathering and UX design to deployment, staff training, and ongoing maintenance — we own the entire delivery lifecycle.

RESEARCH-GRADE OUTPUT

Our work is published in peer-reviewed journals and presented at WIOMSA symposia. The rigour of academic research underlies every system we build.

Data Management Systems

// turning field records into institutional knowledge

Fragmented data is the primary bottleneck in coastal resource management. We design and build centralised database systems that unify catch registers, governance records, socioeconomic surveys, and spatial datasets — making them queryable, shareable, and secure.

Our flagship delivery was the Kenya National Marine Fisheries Information System (KNMFIS) for Kenya Fisheries Service, a live production system handling inshore and offshore fisheries data for all coastal counties.

Harmonised Databases

Multi-source data integration across BMUs, KoBoCollect, and legacy spreadsheets into a unified schema.

Secure Multi-User Access

Role-based access for national agencies, county departments, NGOs, and field teams.

Automated Reporting

Scheduled report generation for donor compliance, management decisions, and regulatory submissions.

API Integration

RESTful APIs connect to external systems including bulk SMS, GIS layers, and national registries.

GIS & Spatial Analysis

// putting your resources on the map — literally

Decisions about fishing ground boundaries, mangrove extent, MPA zoning, and port city land use require accurate spatial data. We produce publication-quality maps and interactive GIS platforms grounded in remote sensing, field surveys, and community knowledge.

Our GIS work spans from SAR-based mangrove forest carbon monitoring (RCMRD/SERVIR) to fishing ground mapping across the Malindi-Watamu seascape — including gear type, seasonal variation, and fisher origin.

Fishing Ground Mapping

Spatial mapping of fishing activity patterns by gear type, origin, and season for BMU management plans.

Remote Sensing Analysis

SAR and optical imagery for mangrove, land cover change, and coastal habitat classification.

Interactive Web Maps

Folium and Leaflet-based interactive maps deployable in dashboards and web portals.

Marine Spatial Planning

Decision support tools integrating economic and environmental layers for informed MSP processes.

Web & Mobile Applications

// field-ready tools that people actually use

We build web platforms and mobile applications designed for East African field conditions — intermittent connectivity, varied device capability, and multilingual users. Every interface is tested for real-world use, not just demo environments.

Our mobile work includes KoBoCollect-based data collection, React Native cross-platform apps, and Android applications for fish traceability, solid waste management, and SACCO administration.

Offline-First Design

Applications that capture and sync data even when connectivity is unavailable.

Budget Accountability Platforms

Transparency and participation platforms for county budgets, NGO programmes, and community funds.

e-Learning Platforms

Virtual classroom systems deployed across colleges, supporting exams, chat, and attendance.

SACCO Management Systems

Full-featured member registration, loan workflow, and accounting automation for SACCOs.

Monitoring, Evaluation & Learning

// showing donors what actually happened, in real time

We design M&E frameworks from the ground up and build the digital infrastructure to support them — from KPI dashboards and indicator tracking to automated impact reports and donor-compliant output visualizations.

Our COMRED Programme M&E Portal combines Leaflet maps, Gantt charts, and indicator dashboards in a single web platform deployed on a VPS. We also build Power BI and Tableau dashboards integrated with field data pipelines.

M&E Portal Development

Custom web portals with indicator tracking, beneficiary maps, and automated progress reports.

Power BI Dashboards

Real-time dashboards connected to field data — for staff appraisals, project outputs, and community metrics.

Survey & Data Tools

End-to-end survey design, KoBoCollect deployment, data cleaning, and analysis pipelines.

Impact Evaluation

Community impact assessments combining qualitative interviews, socioeconomic surveys, and statistical analysis.

Machine Learning & AI

// pattern recognition at coastal scale

Our published research and applied deployments span route optimization for solid waste collection, sentiment analysis of fishing community social media, NLP-based monitoring, and predictive modelling for fisheries stock assessment.

We apply ML where it provides demonstrable uplift over conventional methods — not as a default, but as a rigorous choice supported by validation data.

Spatial Optimization

Route optimization and resource allocation models using GIS + ML for urban and coastal services.

NLP & Sentiment Analysis

Deep learning models for analysing community feedback, compliance signals, and social media data.

Predictive Analytics

Time-series forecasting and pattern detection for fisheries management and environmental monitoring.

Social Network Analysis

Mapping relationships and information flows within research networks and community governance structures.

Community Digital Tools

// financial inclusion at the last mile

Fishing communities and women's savings groups need practical digital tools, not enterprise software. We design Excel-based financial management workbooks with VBA automation, loan tracking dashboards, and group accounting systems tailored for low-connectivity environments.

Our community tool work includes Excel workbooks for SAMAHCO and Baharini Women Groups, business plans for six coastal self-help groups, and group management systems for mangrove conservation monitoring.

Savings Group Workbooks

Automated Excel workbooks with VBA macros for contributions, loans, interest, and share calculations.

Business Planning Tools

Structured business plan templates and financial projections for community enterprise groups.

Conservation Tracking

Mangrove replanting, community patrol, and biodiversity monitoring trackers for BMU field teams.

Training & Capacity

Digital literacy training programmes tailored for fishing community stakeholders and BMU leadership.
