Frequently Asked Questions
Got questions about our specialized technology solutions? We have the answers to help you make informed decisions.
Skip past the summary and go straight to the portfolio examples, the full text of client reviews (not just the star rating), and how long the company has been operating. Reviews that mention specific, measurable results — a faster checkout flow, a successful migration, fewer support tickets — tell you far more than generic praise. It's also worth checking whether the Generative AI firm responds to reviews at all, since that habit tends to mirror how they handle feedback during an actual project.
Rankings for Generative AI companies are built from a mix of verified client reviews, the depth and relevance of each firm's portfolio, market presence, and how responsive they are on the platform itself — not a single self-reported score. Our team cross-checks submitted project details against client interviews wherever possible, so a company sitting near the top of the list has that position backed by more than its own marketing.
Bring a real problem from your own project to a discovery call and see how the team engages with it — the quality of their follow-up questions tells you more than any slide deck. Ask to see actual code from past work, not just screenshots of the finished product, and look for evidence of technical writing, open-source contributions, or conference talks, which are harder to fake than a polished portfolio page. A Generative AI company with genuine depth won't be shy about any of this.
Look past the pitch deck: read the portfolio for technical substance, check independent reviews rather than the testimonials on the company's own site, and ask for a reference from a project similar in scope to yours. Then ask directly how they handle QA and what happens when a bug slips through after delivery. A Generative AI company that's confident in its process will answer that last question specifically, not with a vague reassurance.
Most will, as long as the scope is genuinely locked down — clear requirements, a defined timeline, and agreed deliverables. Fixed-price contracts with Generative AI companies tie payment to milestones rather than hours worked, which is good for budget predictability but only works if everyone agrees upfront on what a change request looks like. Make sure that process is spelled out in writing before work starts.
Look for Generative AI companies that offer dedicated-team arrangements and can point to client relationships that have lasted multiple years, not just multiple projects. That kind of continuity usually means the firm treats your product roadmap as something they have a stake in, rather than a queue of tickets to clear. Ask directly for a reference from a client they've worked with for two-plus years — the answer (or lack of one) tells you a lot.
Start by writing down what "done" actually looks like for your project — the core features, the platforms it needs to run on, and a rough budget ceiling. From there, narrow your list to Generative AI agencies whose past work matches that scope, and put each one through the same first conversation: a real problem from your project, presented cold, to see how they think rather than how they pitch. The Generative AI company that asks the sharpest follow-up questions is usually the one worth a second meeting.
Rates for Generative AI developers spread out quite a bit depending on seniority — junior developers sit at one end, senior engineers and architects at the other, with company size and specialization shifting things further. What tends to hold across the board is that Generative AI developers come in noticeably cheaper than comparable talent in the US or Western Europe, without a proportional drop in the quality of work.
