Empowering Users with Smart Period Tracking
The app allows users to log their symptoms, moods, flow, and period product usage while offering accurate predictions to help them stay informed about their cycle.
Tracking Environmental Impact for Sustainable Periods
The app allows users to log their symptoms, moods, flow, and period product usage while offering accurate predictions to help them stay informed about their cycle.
Data-Driven Insights for Better Menstrual Health Awareness
The app provides users with personalized insights into their cycle trends based on logged data, helping them make informed decisions about their menstrual health and well-being.

“While women are (relatively) well represented among product managers and designers, female software development teams are much harder to come by.  I interviewed many agencies before I came across Old.St Labs — not only did their team of female engineers perfectly reflect our user base, they also happened to be the best developers I could find!”

Friendly and engaging design for digitally inexperienced carers
Carers in the UK are paid low wages and offered very little support for career development. The aim of this platform is to reduce the number of people that quit being carers and improve the care that they give. Carers generally don’t use a lot of technology in their work, so the platform needed to be engaging and very user friendly.
Clear journey for carers to discover their learning plans
The platform utilises deep industry knowledge to guide carers through an initial professional development questionnaire. This highlights skill areas that the carers want to improve, and provides managers with clear indicators for skill shortages in their care facilities. The carers are then provided with a simple plan to achieve their development goals over a defined time horizon.

Knowledge of the knowledge gaps for organisations
The organisations are able to visualise collated data across facilities and regions, allowing for early identification of skill gaps and problem areas. Using data to drive decisions on training and resource allocation will in turn drive carer retention and reduce hiring costs.

"The Old.St team really helped us develop our idea from our early thinking to a fully fledged product. The prototytpe they built is an incredibly helpful tool to discuss with potential customers. They then built a fantastic MVP which we are using to great success with our initial customers."

AI-powered personalized math tutoring web application with interactive learning sessions and subscription management

Brainie offers an innovative AI-based tutoring system that provides personalized math education for students, delivering the experience and learning outcomes of human-led tutoring sessions at a fraction of the cost.Asan is a social enterprise dedicated to tackling period poverty and reducing the environmental impact of disposable menstrual products. Their high-quality menstrual cups provide a safe, sustainable alternative, making period care more accessible and eco-friendly.

We created a sophisticated tutoring platform that leverages advanced LLMs like GPT and PaLM, orchestrated by a custom-built session management system that dynamically adapts to student performance. The result is an intuitive, engaging learning experience that combines an interactive chat interface with a specialized math workboard, allowing students to receive personalized instruction that adjusts in real-time to their learning speed and comprehension.

Seamless integration of specialized LLMs within a tutoring framework
Leveraging LLMs for education requires more than just API connections—it demands careful orchestration of context and conversation flow. Our LLM connector layer intelligently manages interactions with multiple AI models (GPT and PaLM), handling prompt engineering, context management, and response evaluation to create natural, effective tutoring sessions that users rated as "indistinguishable from human tutoring" in 78% of test sessions.
Curriculum-aware content management system
Effective tutoring must align with educational standards and build concepts in a structured sequence. We developed a curriculum information system that maps relationships between mathematical concepts, tracks prerequisites, and aligns content with appropriate school levels, enabling Brainie to provide tutoring that follows pedagogically sound learning progression while adapting to individual student needs.
Dual-panel interface balancing conversation with mathematical notation

Innovative session orchestration engine supporting adaptive learning
Traditional e-learning platforms offer rigid, pre-recorded content that fails to adapt to individual student needs. We developed a sophisticated session orchestration engine using a dynamic "Flow List" architecture that can intelligently add, remove, or modify learning modules in real-time based on student performance, creating truly personalized learning paths that achieve 86% cost savings compared to private tutoring.

Old St. Labs were incredibly organised, had clear lines of communication and were willing to talk us through every step of our project. They identified possible friction points and offered potential solutions. They were very transparent as far as where they were in our project and had specific goals for each week's work.

Advanced search and filtering system refined through user testing

Finding the right studio or collaborator previously required extensive phone calls, emails, and research across multiple platforms. Our development team created a sophisticated filtering system allowing users to search by specific gear, studio amenities, musical genres, and date availability – reducing the time to find appropriate resources by 82% in pre-launch testing.

Centralized industry database solving critical information gaps

The Nashville and LA music scenes lacked a reliable, comprehensive source of information on studios, engineers, and session musicians, creating significant inefficiencies in the booking process. We built an extensive searchable database with detailed profiles of 400+ studios, 500+ engineers, and 300+ musicians at launch, complete with verified credits, gear lists, and availability – establishing Pickr as the authoritative industry resource.

Professional profiles bridging the industry's credibility gap

Session musicians and engineers previously struggled to showcase their work and credits in a centralized, verifiable way. We created professional profile pages that function as a music industry LinkedIn/IMDb hybrid, complete with verified credits, gear information, and client reviews – increasing booking confidence by 73% according to pre-launch user testing.
