Frequently Asked Questions

What does Entexis actually build?
Custom software for your business. AI systems, SaaS platforms, CRMs, internal tools, and enterprise systems that fit your workflows. Not off-the-shelf products with a coat of paint. Live examples on this site include AI voice agents that book appointments, document Q&A systems that read your contracts, and custom CRMs tuned to specific industries.
How is Entexis different from other development companies?
You get a team of engineers who have built custom software for 12+ years across 5 continents and 2,100+ engagements. What separates the work is domain-first thinking. We spend time inside your industry before writing code, so what you get actually fits your workflows. Most companies flip that order and hope for the best.
Do you work on hourly, fixed-price, or something else?
All of them. Hourly for open-ended work, fixed-price for well-scoped builds, milestone-based for larger multi-phase engagements, and hybrid where it fits. The right model depends on how well-defined your scope is. Whichever you pick, you get outcome accountability, not just billable hours.
Who owns the code after the build?
You do. Every line of code, every schema, every integration is yours. We build on standard tools your team can maintain, so no black boxes, no proprietary layer, no vendor lock-in that keeps you dependent on us. When the engagement ends you own everything and can hire anyone to extend it.
Can Entexis work with our existing setup?
Yes. Across the common backend languages (Node, Python, Java, .NET, PHP), the common databases (Postgres, MySQL, MongoDB, MSSQL), any of the major clouds (AWS, GCP, Azure) or self-hosted, and modern AI models (OpenAI, Anthropic, open weights). If your team runs on it, you get a build that plugs into it.
Do you consult if we are not ready to build?
Yes. Sometimes the honest answer is not to build yet. Maybe an existing tool with 3 configuration changes covers 80% of what you need. Maybe a simpler workflow beats new software. We tell you when that is true. When a build IS the right move, we scope it properly and deliver. Either path, you get a clear answer instead of a sales pitch.
Can Entexis build custom AI for a business like ours?
Yes. Whether you are a small business, a growing SaaS, an enterprise, or an e-commerce brand, we build AI and workflow automation that fit how your team actually works. Chatbots, voice agents, document intelligence, decision support, process automation, or something bespoke to your domain. Start with a conversation about what you are trying to achieve. We scope the build to what your problem actually needs, no bigger and no smaller.

What Gap in Your
Industry Are You
Building For?

No pitch decks. No RFQ forms. No 47-slide proposals. Just a conversation about your industry, your problem, and whether we're the right team to solve it. We'll be honest if we're not.

We'll get back within one business day.
