Series Ventures invests in WithDoctors to advance data-driven pediatric growth care

Series Ventures, a specialized accelerator, has completed a seed investment in WithDoctors, a company focused on pediatric and adolescent growth care. The specific amount of the investment was not disclosed in the report. StartupN reported the story.

WithDoctors, established in 2024, operates a data-based growth care service that integrates medical, exercise, nutritional, psychological, and sleep management into a single system. The company holds a corporate research institute certification and venture enterprise status. It addresses a market gap where many existing services focus narrowly on specific areas such as injections or examinations, rather than managing the child's overall living environment and growth process continuously.

The company collects data through precise examinations covering more than 210 items and designs individual growth strategies with a team of expert-level professionals. Its differentiation lies in a self-developed growth management CRM and an AI growth management platform. This system integrates examination, questionnaire, and prescription data to automatically generate individual growth evaluation reports. The company plans to expand AI-based functions using accumulated data for growth prediction, analysis of growth-inhibiting factors, and personalized program recommendations.

WithDoctors has accumulated over 70,000 examination data points. The company reports a re-registration rate of over 80% for its three-month program, a figure presented as its own operational performance. It also operates a proprietary care principle called the RESST system to set management directions based on collected information. Currently, the company operates its first location in Hanam and is preparing to open a second location in Daechi.

The growth care market is expanding, driven by increased parental interest in children's health and the trend of high spending on single children. The health functional food market for height growth has grown by more than 800% over the past five years, reaching an estimated 259.9 billion won. Series Ventures co-representatives cited the team's ability to integrate fragmented growth management areas and standardize them with data and AI as the investment rationale. WithDoctors' representative stated that the company aims to expand data-based growth care so more children can realize their growth potential. However, proving the accuracy of data-based predictions and AI analysis requires sufficient long-term data and objective verification, which remains a key challenge for future expansion.
