K Health Saves Hundreds of Thousands on BigQuery

DoiT optimized BigQuery queries and secured HIPAA-compliant Google Cloud infrastructure as K Health scaled AI-powered care to 4 million users.

Meet K Health

K Health combines the simplicity of a symptom checker with AI-powered recommendations and telemedical advice. Users answer a 20-point questionnaire about symptoms, and K Health's machine learning algorithm compares their profile with a 20-year database of over 400 million clinical notes. The platform provides likely diagnoses and connects users with doctors through HIPAA-compliant messaging. With more than 4 million users, K Health is the most downloaded medical app in the US.

The Challenge

K Health needed to scale their container-based backend on Google Kubernetes Engine while ensuring security for sensitive health data and optimizing cloud costs. They required specialized expertise to handle HIPAA-compliant data processing and efficient BigQuery operations as they grew their user base.

The Solution

DoiT provided architectural sessions for secure handling of sensitive health data on Kubernetes Engine and BigQuery. They helped create secure environments for AI researchers, optimized daily and hourly BigQuery queries, and provided ongoing support for cloud infrastructure management.

Results

Achieved hundreds of thousands of dollars in cost savings over three years through BigQuery optimization
Secured sensitive health data processing for 4 million users with HIPAA-compliant infrastructure
Enabled faster feature releases and expanded medical condition coverage including pediatric care

The scope of what we're trying to do is very ambitious, and we're moving fast. On this journey, DoiT opens up opportunities we wouldn't have discovered otherwise, and then helps us actually realize these opportunities with the right technologies. It's been a superb experience so far, and we're excited to get even more out of our partnership in the future.

Securing Access to Sensitive Information

DoiT prioritized security by hosting architectural sessions to support K Health in handling sensitive health data on Kubernetes Engine and BigQuery. They provided tailored support for specific security challenges, including creating secure environments for AI researchers to access sensitive data. DoiT helped de-identify customer data and protect against leaks, enabling the AI team to improve their solution securely.

Reducing Costs Through Query Optimization

The DoiT team reviewed K Health's infrastructure and discovered inefficiencies in daily and hourly BigQuery queries. They provided optimization guidelines that resulted in significant cost reductions. This optimization work culminated in a deal that will save K Health hundreds of thousands of dollars over three years while supporting their continued growth.

Building Cloud Confidence with Expert Support

DoiT provides reliable support with immediate access to deep expertise in K Health's timezone. Their in-depth responses help K Health's engineering and security teams become more confident with cloud technologies. DoiT also supported Google Workspace integration and training sessions, improving team productivity with tools like Gmail and Google Drive.

Making Healthcare More Accessible

With DoiT's support, K Health continues innovating their healthcare solution and releasing new features faster. They've expanded coverage to more medical conditions and launched a symptom checker specifically for children, providing immediate access to specialists and remote pediatric care. The partnership enables K Health to maintain their vision of affordable, smart, and secure remote care.

What they say

DoiT gave us the confidence to move from experimentation to production. They helped us understand the right way to build AI for the real world.

Milad Rezazadeh, CTO

PerfectScale by DoiT has become an mportant part of how we optimize Kubernetes at scale at OneFootball. It gives our platform team the visibility, automation, resiliency insights, and confidence we need to balance cost efficiency with production readiness, especially as we prepare for major global football moments like the 2026 FIFA World Cup.

Andrea Benfatto, Platform/Cloud Runtime Engineering Manager

Cloudflow's new RDS End of Life alerts have allowed us to be more proactive on keeping our database instances up-to-date. The new solution gives us internal visibility ahead of time so that we can prepare for upgrades, instead of having to upgrade under pressure while incurring extended support costs.

Jon Fairbanks, Site Reliability Engineering Manager

PerfectScale cut 40% off our total EKS spend, and the automations handle what used to take our team 20 hours a month. Now we spend that time on reliability and performance instead of chasing cost metrics.

Caio Cristo, Director of Infrastructure/SRE

What I really like about DoiT's approach is that you're very hands-on and proactive. Satyam would ping me a few times a sprint, letting me know about the most current features, checking in on how things are going. When we are going through a peak time, that proactiveness makes a real difference. Satyam always comes through whenever we need support and helps us leverage the right experts to get us where we need to be.

SELECT has made important cost data readily accessible. I will often pull it up during engineering design reviews so we can quickly evaluate cost impact and projections and factor that into our design decisions.

Douglas Zickuhr, Senior Data Platform Engineer at Personio

I love clicking through SELECT to understand how our environment and workloads are evolving. I probably check it every day. It's coffee and SELECT for me every morning.

Ian Fahey, Senior Analytics Engineer at Loop

You guys have the best UI experience that I've had of any software. It's like you just read my mind where, like, oh, I wish I could click there. Oh, I can

Diana Koshy, Sr. Director of Data Engineering at Kargo

SELECT feels like exactly what Paul and I would have built if we had locked ourselves in a room for 18 months to create our ideal monitoring solution.

Devin McGee, Data Engineering Lead at Home Chef

SELECT dramatically lowers the cognitive load to understanding Snowflake costs. I'm able to sit there and easily understand what's driving the cost. Not to blow smoke up your ass, but it's just so easy to do in your platform

Blake Baggett, Head of Data Operations at Entain

One of the most helpful cost rituals we've setup from SELECT is the weekly spend digest sent to Slack. I can start high level and ensure things are in check. If not, I can very quickly drill down into specific workloads which may have driven the cost spike and remediate them before they become a bigger issue.

Michael Revelo, Manager of data and analytics engineering at ClickUp

Through SELECT's automated savings feature and deep cost visibility, we were able to instantly lower our Snowflake spend by over 40% and achieve a 20X ROI on our SELECT investment.

Skyler Chi, SVP, GTM Productivity & Excellence at Exiger

Our costs had jumped up 3X as we scaled, so we're talking about 60% savings in Snowflake spend after adopting SELECT.
