64 companies with evidence of voice AI work in Warsaw; 26 meet the ranking criteria. Sources: 63 by their Clutch profile, 3 by their own website, KRS records, available financial statements and employee reviews. If one senior engineer is enough, I build AI features with AI agents.
Best for: Media and streaming companies that need OTT apps, smart TV players or AdTech platforms.
Verdict. Go with Oxagile for a streaming or AdTech product that needs specialists across many TV platforms. For a Polish contract with a local team, confirm who works from Warsaw.
Pros
Net profit of 134,700 PLN in 2025 on 2,100,000 PLN revenue. (2026-10-28 · source)

The contact page lists an office in Warszawa. (2026-10-28 · source)

Best for: Nonprofits and publicly funded US health programs that want a small team to add generative AI to existing software.
Verdict. Choose Freeport Metrics for an AI feature in a US-facing product built by a small team. For Polish public tenders look elsewhere, since its government work is all in the US.

Projects & technologies
Source observations

The FAQ names Warsaw as headquarters, while the footer gives a registered address in Boston, MA (source).
The case studies page names no clients and warns that client details may be generalized or modified (source).
Innowise sells staff augmentation openly, promising CVs in 1 to 2 days and a team joining in 3 to 5 days (source).
Best for: Mid-size firms in manufacturing, finance or law that want a document chatbot or voicebot running within weeks.
Verdict. Pick Websensa for a knowledge chatbot or voicebot built on its ready platform. For a custom system from scratch, choose a firm that sells engineering time first.
Pros

Clutch rating of 4.9/5 from 13 client reviews. (2026-10-28 · source)
Best for: Companies that need a large dedicated team fast, across many technologies, and can run it with their own product owner.
Verdict. Use Andersen to scale a team you lead, backed by 129 Clutch reviews. Check who signs the contract, given the thin Polish margin and the multi-entity setup.

Body leasing, product companies and other services 3
Renting people into someone else’s team is a different service from delivering a project. A product company, a marketing agency or an SAP partner does not sell software projects either. They are in the full table with a label.

Without 5 Clutch reviews or 2M PLN of revenue in a filing there is no fair way to compare a company with the rest. That is a data gap, not a verdict.

What they charge
On Clutch, the companies in this table most often declare 50 to 99 USD an hour. The rate is what the agency bills; the developer on your project is paid less than half of it.
For comparison, my own rate is 36 to 54 USD an hour (45 USD base, pricing). The cost estimator shows what a project like yours costs with and without coding agents.
25-49 USD/h20

Rates declared on Clutch, 60 companies with an office in the city.
Check any agency yourself in 10 minutes
Call their bot yourself and time the reply: more than a second of silence feels broken on the phone. Ask how it handles interruptions, accents and a transfer to a person.
Find the legal entity in the National Court Register: the seat, the share capital and the shareholders. An office here with a seat in another city is a sales office, not a team.
Read the last financial statement in the Financial Documents Repository (free, by KRS number): revenue, profit or loss, and whether it was filed on time.
Check the VAT white list: active, and the name matches the contract.
On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
Ask who exactly will work on your project, and check those people on LinkedIn.

Questions
What are the best voice AI software houses in Warsaw in 2027?
By the score on this page: 1. Modsen (83), 2. Oxagile (82), 3. Freeport Metrics (82), 4. Plavno (75), 5. Innowise (70). The score adds up transparency in the court register, client reviews on Clutch, profit and stability in the latest filing, specialization and current hiring. The full table shows every company in the data set.
How much do voice AI agencies in Warsaw charge?
Most companies in this table declare 50 to 99 USD an hour on Clutch. My own rate as a senior engineer working with AI agents is 36 to 54 USD an hour.
How do you know a company does voice AI?
From at least one of three sources: the service, industry and framework shares on the Clutch profile, the skills in open roles on JustJoin.it, or the Wrocław company catalog. Companies with two or three sources score higher on specialization. The software house finder shows the same tags for every company.
Did any company pay to be on this list?
No. There are no paid placements and no affiliate links. The only business interest is mine: I sell senior engineering as the alternative to an agency.
Can I get my company added or corrected?
Yes. Write to ciunkos@gmail.com with the KRS number and the correction.
How this ranking was made

Sources: Clutch profiles and listings, KRS records, available financial statements from rejestr.io and the Financial Documents Repository, GoWork reviews, JustJoin.it and No Fluff Jobs listings, and the Wrocław company catalog. Coverage varies by company; dates and links accompany the available records. The 0 to 100 score combines five axes: transparency, client reputation, stability, specialization and activity. Paid Clutch placements do not increase the score.
Disclosures
Until November 2026 I work at Sanddev (Wrocław) as the founding engineer of its Sandtime product. Sanddev appears in the full table with the same score as everyone else and no editorial favor.
No agency pays for a position, there are no affiliate links. If any of that changes, the disclosure changes first.
My business interest is on every page: I sell senior engineering with AI agents as the alternative to hiring an agency.
Written with AI (Claude) from the data set. Every number in the editorial text is checked automatically against the company record or the research notes, source links and dates accompany the available company records.
Przemysław Zalewski, a senior full-stack engineer in Wrocław with 15+ years of shipping software. I build with coding agents, work with clients in the US and the UK, and I sell the alternative to the agencies on this list.
“a true bias for action” client CTO, public LinkedIn recommendation
Confidential by default. NDA is standard. I never show your project, name or screenshots without written consent, which is why this site names no clients without permission.
Your code, your accounts. Code and data stay in your repository and accounts. AI tools run with training on your data turned off, and secrets never reach a model.
A handover you can use. Every project ends with the same checklist: a README that gets it running, one architecture diagram, written decisions, CI, a runbook and a recorded walkthrough. It is done when someone outside the project can run it from the docs.
Boring technology where it counts. I pick a stack you can hire for. Anything experimental needs your yes and an exit plan.
Approach matched to your risk appetite. Prototype, product or regulated: the level decides how much autonomy the agents get and how much review and validation each change needs.
Everything checkable. Every number on my pages links to its source. My tools are free, and the idea validator skill is open source (MIT).
My pledge
Reply within 24 hours. I reply within 24 hours on working days, personally, not a bot. Weekend messages: by Monday noon.
Late means free. If I am late, the first hour of work is free. You do not have to ask.
Scope in writing within 24 hours. A free 30-minute call with no company deck, then the scope and the price in writing within 24 hours. You decide.
The person who does the work. You talk to the person who does the work. No sales layer, no handoff.
Follow-up only with news. I follow up only when I have something new for you. Never a "did you see my offer".
Honest "not a fit". If I am not the right person, I say so on the call and point you to someone who is.
