What We Solve How We Work Work Tenlyr Infra About Contact
PRODUCT ENGINEERING FOR SAAS & AI

Your product works. Then something underneath starts getting difficult.

Tenlyr helps SaaS and AI product teams find and fix the backend, performance, infrastructure and engineering problems that show up as the product grows.

Where are you?

Where are you right now?

The technical problem usually changes depending on where the product is.

01 / BUILD

We're building something new.

We want to move quickly without creating foundations we'll have to replace later.

See how we help →
02 / GROW

We're growing.

The product works. Usage is growing. Something underneath is starting to hurt.

See how we help →
03 / UNBLOCK

Something is already difficult.

Performance, technical debt, infrastructure or an old backend is slowing the team down.

See how we help →
04 / AI → PRODUCTION

Our AI feature works... but now what?

The demo works. Production brings retries, queues, costs, failures and real users.

Sound familiar?

Maybe you're here because...

“The product works fine right now. I'm just not sure what happens when usage grows.”
“Our AI feature works. Production is becoming expensive and unreliable.”
“Our engineers can build features. But every change seems to touch something else.”
“We know something is wrong with the backend. We just can't see exactly where.”
“We're growing faster than the architecture we started with.”
Problems we solve

The problems usually don't arrive with a warning.

They start small. An unindexed query, an unbuffered queue, an unaccounted token stream.

01 · LATENCY

Slow API

One endpoint starts taking 800ms. Then 2 seconds. Then everyone notices.

02 · DATA LAYER

Database pressure

More users don't always mean more servers. Sometimes they mean your queries need to change.

03 · AI AT SCALE

AI cost

The feature works beautifully. Until real users start using it.

04 · ARCHITECTURE

Technical debt

The code still works. It's just getting harder to change.

05 · SCALING

Infrastructure

The product is growing faster than the assumptions your infrastructure was built around.

06 · CAPACITY

Engineering bandwidth

Your team knows what needs to happen. They just don't have the bandwidth to stop everything else and solve it.

What we actually do

We find what's getting in the way. Then we fix it.

Full Service Breakdown
01 — DIAGNOSE

Find the real problem.

We look at the product, architecture, database, APIs, infrastructure and the way users actually interact with the system.

Architecture Database APIs Infrastructure Performance AI workloads
02 — FIX

Work alongside your team.

We don't stop at recommendations. When the problem needs implementation, we work with your team to fix it safely.

Backend refactoring Performance tuning Database optimization Infrastructure changes AI productionization Technical debt
03 — STRENGTHEN

Make the next change easier.

The goal isn't just to fix today's bottleneck. It's to leave the system easier to operate, change and grow.

Operational playbooks Foundation hardening Observability Zero regressions
Interactive story

The product doesn't usually break at 10,000 users.

It breaks when the way people use it changes.

SQL DATABASE
Everything feels fine. Simple database connection pool, monolithic runtime, predictable synchronous request loop. No cache synchronization bugs yet.

Growth doesn't just add users. It changes the engineering problem.

That's where Tenlyr comes in.

Rajesh Ayyavu Founder · SaaS Architect · Tenlyr

I started Tenlyr around a simple observation: most product problems don't start as big problems.

A slow query. A workaround. A feature that's getting harder to change. An AI workflow that works in a demo but becomes expensive in production.

Eventually, those small decisions become the thing slowing the product down. That's the kind of problem I like working on.

No sales team. No handoff. Just a conversation about what you're building and what's getting difficult.
Built from repeated engineering problems

We got tired of rebuilding the same foundations.

Authentication. Organizations. Permissions. Multi-tenancy. Core APIs. Infrastructure. So we built our own foundation layer.

Something is getting difficult?

You don't need to know exactly what's wrong before talking to us. Tell us what's happening. We'll figure out whether there's actually a problem worth solving.
