Meet Taxfix
Taxfix is Europe's leading mobile tax app with millions of downloads in Germany, Italy and Spain. Their mission is to make complex tax systems accessible to everyone and allow users to submit tax returns quickly and easily via app or web, ultimately unlocking financial well-being for everyone. The Taxfix app helps taxpayers claim the highest possible tax refunds by guiding users through the process of filing their taxes by asking them simple questions as a tax advisor would. The company recently surpassed the milestone of two billion euros in tax refunds returned to their customers.
The Challenge
When expanding into additional regions, Taxfix must account for legal and cultural differences across countries, including local tax-filing norms. Tax declarations require precise and reliable government-provided datasets, which vary by country. Taxfix must conduct thorough analyses to ensure its Google Cloud framework adheres to industry standards, local norms and expectations, and is resilient to unexpected events.
The Solution
Since 2020, Taxfix has relied on DoiT's expertise across Google Cloud, Kubernetes, and Google Maps Platform, and adopted DoiT's world-class first-line support. Taxfix also benefits from specialized consulting and DoiT's proprietary cloud technologies, which increase confidence in decision-making and reduce costs significantly. DoiT provides direct access to experts for implementation guidance and tool selection as Taxfix enters new markets.
Results
- Focus on developing and launching new products while expanding product line
- Successfully launched 'Do it for me' service connecting users with tax advisors
- Continued international expansion with DoiT expertise informing decisions
It may appear too good to be true, and we were initially skeptical about it when we signed up, wondering what the catch might be. However, we decided to have faith in DoiT and give it a chance. Once you get past your skepticism, you will appreciate the value of its services and expertise.
Ilya Kozlov, VP Engineering
Google Maps Platform Integration
To diversify and adapt its products, Taxfix prioritizes core services compute, Kubernetes, networking, and databases over advanced features. Taxfix complements its offering with user-friendly Google Maps Platform services such as Place Autocomplete, and leverages the Geocoding API and Directions API to help users provide accurate addresses used to calculate daily travel distances for commute-related deductions. With Google's global reach, Taxfix replicates and adapts its architecture for target regions while maintaining an optimized user experience.
DoiT Partnership and Support
Since 2020, Taxfix has relied on DoiT's expertise across Google Cloud, Kubernetes, and Google Maps Platform, and adopted DoiT's world-class first-line support. Taxfix also benefits from specialized consulting and DoiT's proprietary cloud technologies, which increase confidence in decision-making and reduce costs significantly. In Germany, Taxfix continually expands its customer base and serves new segments. Amid market changes, Taxfix stays responsive to customer needs and uses DoiT's products to forecast costs and plan potential architectural upgrades.
Results and Future Growth
Taxfix can focus on developing and launching new products and services while expanding its product line, such as the recently launched 'Do it for me' service. For complex situations or when users prefer assistance, Taxfix connects them with a tax advisor who can answer questions and take over the declaration process. As Taxfix expands into new markets and develops more services, it continues to rely on DoiT's expertise to inform decisions and keep the focus on users.

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 important 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.
Chiamaka Ibeme, Engineering Manager, Platform
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.
Edward Mancey, GTM Lead at Synthesia
