About Stratoflow: Java engineers for systems that cannot slow down
A boutique team of senior engineers in Poland, founded in 2013 and still run by the two people who started it. We build, modernize and support business-critical Java platforms for companies in the UK, the US and Western Europe.

What you can hold us to
The people in the pitch write the code
Every engineer is a direct employee, and we do not subcontract development. With 7% attrition, the team you meet is the team you keep.
A number before a discovery workshop
After the scoping call you get a written ballpark range with its assumptions and a validity period. Scope changes are priced before the work starts.
Progress you can see
Working software demonstrated every week. You try it, tell us what to change, and the next iteration starts from your feedback, not from a status report.
Still here in year three
Every engagement ends in a documented handover or moves to managed support with SLAs. Our longest client relationship is past ten years.
Thirteen years, one team
- 2013
Founded in Poland
Two founders and a first client, Legerity. Over nearly ten years we built FastPost, a rule-driven accounting ledger that is still in production and clears a billion transactions in under an hour.
- 2019
300 million hotel searches a day
We redesigned the metasearch engine of a major UK hotel aggregator: up from 200 million queries a day, response time down 60%, infrastructure cost down 80%.
- 2022
Our own product, acquired
Recostream, the recommendation engine we built and ran in-house from 2019, answering in 20 to 30 ms, was acquired by GetResponse in December.
- 2023
The founders start Openkoda
A separate company building an insurance platform. Stratoflow becomes its implementation partner, taking insurers from contract to production.
- Today
Six industries, one team
We modernize, speed up and support the Java platforms behind banks and fintechs, insurers, travel and ecommerce operators, property businesses and technology companies.
The founders
Michał Głomba, co-founder and CEO
Runs the company and most client relationships, and decides with you whether Stratoflow is a fit at all. Fifteen years in financial systems before Stratoflow, plus two startups since: a recommendation engine acquired by GetResponse and the Openkoda insurance platform.
Arkadiusz Drysch, co-founder and CTO
Led the engineering behind a ledger that clears a billion transactions an hour and a metasearch serving 300 million queries a day, and architects the Openkoda platform. Previously a CIO and board member, and a consultant on financial and industrial systems.
The developed software product was built from scratch with solid quality. We have had a long-term engagement with Stratoflow for nearly 10 years. We look at them as partners, rather than contractors. I'm impressed by their team culture and cross-team support.
When we are not the right team
- You need fifty engineers next month. We are a boutique firm and we do not subcontract.
- The lowest hourly rate decides the deal. An offshore staffing firm will beat us on price.
- A packaged product would do the job. Buy it; we will tell you so on the scoping call.
Company details
Clients across Europe and the US
We work with companies in the UK, the US and Western Europe, in banking and fintech, insurance, travel, ecommerce, real estate and technology.
Code you own from day one
Work happens in a repository you own from the first commit, with documentation and tests in the agreed scope, so the system stays yours whoever runs it next.
Working hours that overlap yours
Poland is one hour ahead of London (CET), so our working day covers UK business hours in full and the morning on the US East Coast.
