Which kind of team fits?Pick one

The short answer

Choose a team on how it handles problems after launch, not how fast it ships version one. Ask who will actually do the work, how it keeps customer data separate, what it does when the product gets slow, and what you own at the end. Ask to see a real problem it solved. A team that can explain trade-offs in plain words is usually a safer choice than one that promises everything.

Judge how they handle problems

Not how fast they ship version one.

Ask the same eight questions

Compare the answers, not the pitch.

Own your code and accounts

All in your name from day one.

Eight questions to ask, and what good answers sound like

0 of 8 ticked

Who will actually do the work?Named people with relevant experience, and a way to talk to them. Be careful when sales answers and someone else builds.
How do you keep one customer’s data apart from another’s?A clear, specific answer about tenant identifiers and where the rule is enforced. A vague answer here is the most expensive one.
How do you control who can do what?Roles and permissions in one place, with a way to see and change them. Not rules scattered across screens.
What happens when the product becomes slow?Measuring first, finding the cause, fixing it. Not bigger servers by default.
What do I own at the end?Code, cloud accounts, database, documents and deployment, all in your name from day one.
Can you show me a problem you found and fixed?A real story with the cause, the decision and the result. Case studies that only list technologies tell you little.
How will I know how it is going?Regular working builds you can use, not only status reports.
What would make you tell me not to build this?A good team will say no, or suggest a smaller start. A team that never disagrees is selling, not advising.

Ask every team you shortlist the same questions.

Red flags

Any one of these deserves a follow-up question.

A price with no written scope
You will pay for the gaps later.

Promises of “best” or “guaranteed” with no evidence
Ask for a reference you can call.

The team keeps the code or the cloud accounts
This is how switching teams becomes impossible.

No questions about your customers
They are planning features, not a product.

Microservices and Kubernetes on day one
Complexity before you need it is cost you carry.

What good product engineering looks like

Good product engineering is not just writing code. The team asks about your customers and your plans for the next year before it opens an editor.

It also means saying what not to build yet. A product that launches with fewer features on a sound base is easier to grow than one that launches with many on a weak one.

Development shop, studio or consultant?

Development shop

Good for: You already know exactly what you need

Less suited: You need help deciding what to build

Product engineering studio

Good for: You want help deciding and a partner as it grows

Less suited: You need a very large team fast

Consultant

Good for: You want a review or advice before building

Less suited: You want someone to build everything

Many founders do best with a short independent review first, then choose who builds. The review tells you what you actually need, which makes every quote easier to judge.

Where Tenlyr fits, honestly

A good fit

SaaS and AI products that are growing and starting to hurt. You talk to the person doing the work, Rajesh Ayyavu. We review how your software is built, then help fix what matters if you ask us to.

Not the right choice

If you need a large team of developers to build a big product from scratch quickly. We are happy to review another team’s proposal before you sign it.

See our architecture review and case studies. Tenlyr is a small, founder-led studio in Tamil Nadu, India.

Common questions

How do I choose the right team to build my SaaS?

Judge a team by how it handles problems after launch, not by how fast it ships the first version. Ask who does the work, how customer data is kept separate, how it handles slow pages, what you own at the end, and ask to see a real problem it fixed.

What is the difference between a development shop, a product engineering studio and a consultant?

A development shop builds what you specify. A product engineering studio helps decide what and how to build and stays through growth. A consultant reviews and advises, and may or may not build. The right one depends on whether you need hands, judgement or both.

Should I choose a team in my own city?

Location matters less than working hours, communication and access to the people doing the work. A remote team that overlaps your working day and shows you its work often beats a local one that does not. Meeting in person is useful at the start, not essential.

What should I own at the end of a project?

The source code, the cloud accounts, the database, the documentation and the deployment process, all under your name. If the team holds any of these, you cannot leave without losing something.

Is a fixed price or hourly rate better?

Fixed price suits a small, clearly defined scope. Hourly or monthly suits work where learning changes the plan. Whichever you use, ask for a scope in writing and a way to stop after a short first stage.
