The quiet revenue leak

Every missed call is a customer your competitor just answered.

Most businesses lose 30–60% of inbound demand to silence. After hours. During lunch. When the team is overloaded. Cortiva closes that gap, in voice that feels like your best receptionist on her best day.

What Cortiva does

Built to do the work, not just talk about it.

Answers inbound calls

Picks up in under three seconds. No "press 1." No queue. Knows your business, your services, your pricing, your hours.

Qualifies every lead

Asks the right questions in the right order. Filters tire-kickers. Hands off only the warm ones to your team, with full context.

Books meetings live

Reads your calendar. Offers real slots. Confirms over SMS. The caller hangs up with a meeting in hand, not a "we'll call you back."

Speaks your customer's language

English, Hindi, Gujarati, Marathi, Tamil, Spanish, Arabic, and more. Switches mid-call if the caller does. Sounds native, not translated.

Integrates where you live

Salesforce. HubSpot. Zoho. Calendly. Google Calendar. WhatsApp. Slack. Your CRM, your tools, your stack. Cortiva fits in, never asks you to change.

Learns from every call

Weekly tuning by your team and ours. Every conversation makes the next one sharper. The agent that picks up next month will be smarter than this one.

Hear it for yourself

Press play.
This is what
Cortiva sounds like.

Below is a real production call from a Cortiva agent. Not a demo reel. Not a script. The voice you'll hear is the one your customers will hear when they dial, every day, in any language.

A polite collections call, handled with grace.

Cortiva calls a customer about an overdue invoice. Warm, professional, listens, offers options.

We were missing forty per cent of calls after 8 PM. Now we miss zero. Cortiva doesn't just answer, it sounds like the front-desk we wish we could hire across every clinic.

Clinic Director · Multi-city dental chain
By appointment only

We build for a small handful of businesses each quarter.

Cortiva is not a SaaS signup. Every agent is shaped to the business it runs. The voice. The phrasing. The integrations. The fallbacks. That kind of work doesn't scale to ten thousand customers, and we don't pretend it does.

Bespoke, not template

Every agent is built around how your business actually answers the phone. No generic flows. No "press 2 for sales."

Tuned weekly

Every transcript is reviewed. Every edge case is closed. The agent that works for you in month six is sharper than the one that launched.

Yours, alone

Your data stays yours. Your transcripts stay yours. Your agent is not a shared model serving competitors next door.

The product

Voice agents that
sound like people,
work like systems.

Cortiva builds the voice AI that handles your calls when the office is closed, when the team is busy, and when speed is the difference between a sale and a missed one.

Inbound, outbound, both

Three jobs.
One system.

A Cortiva agent is not a chatbot with a voice attached. It's a full pipeline. Real-time speech understanding, custom logic for your business, calendar and CRM connections, and a voice that, frankly, most callers don't realize is AI.

We build three classes of agent, often deployed together:

Sample interaction
EN-IN
Caller
Hi, I saw your listing for the 3 BHK in Bopal. Is it still available?
Cortiva
Yes it is. It's been on the market for nine days, asking 1.45 crore. Are you looking for end-use or investment?
Caller
End-use. When can I visit?
Cortiva
I have tomorrow 11 AM or Saturday 4 PM with the listing agent. Which works?

Inbound receptionist

For businesses where missed calls are missed revenue. Answers, qualifies, books, and routes. Works in your customer's language, around the clock.

Outbound caller

Calls your leads back in under two minutes. Follows up on quotes. Reactivates dormant lists. Books the meetings your sales team would otherwise miss.

Support agent

Handles repeat questions, status checks, simple resolutions. Escalates anything human-shaped to your team with full context already gathered.

Under the hood

Engineered for the
moments that matter.

A voice agent that pauses for half a second too long is a voice agent that loses the call. Cortiva is built on a custom orchestration layer that keeps latency under 1.2 seconds end-to-end, in any language.

Two real calls.
One voice doing the work.

Below are two unedited production recordings from Cortiva agents. Press play. Listen for the pace, the warmth, the way the agent handles a real human on the line. This is the voice your customers will hear.

Inbound · KYC verification

A full KYC call, end-to-end.

Cortiva verifies a customer's identity over the phone. Collects details, confirms, closes the loop. No human in the loop.

Outbound · Payment reminder

Cortiva reminds a customer about a pending payment. Listens. Offers a way forward. Never escalates without reason.

Capability stack

What's inside every Cortiva agent.

Natural voice synthesis

Not robotic. Not text-to-speech of 2020. Cortiva voices have breath, pace, and warmth. We tune them to your brand.

Custom knowledge base

Your services, prices, policies, hours, FAQs. The agent knows everything a great employee would know, and never forgets.

Live calendar booking

Reads your real availability. Books real slots. Sends real confirmations. No back-and-forth, no double-bookings.

Full transcript & summary

Every call recorded, transcribed, summarized. Pushed to your CRM with the right tags. Your team gets context, not a tape to listen to.

Sentiment & intent detection

Knows when a caller is frustrated, ready to buy, or confused. Adjusts tone and escalates accordingly.

Human handoff, ready

When a call needs a human, Cortiva warm-transfers with a one-line context summary. Your team picks up already in the middle of the conversation.

Common questions

Things worth asking.

Will the caller know they're talking to AI?
We're upfront with you, and we let you choose. Some clients prefer the agent introduces itself as an AI assistant. Others want it indistinguishable. Either is technically possible. Legally and ethically, in most jurisdictions, transparent disclosure is the safer choice, and we'll guide you on it.
How long does it take to launch an agent?
Typically four to six weeks from kickoff to a live, production-ready agent. Two weeks for discovery and design, two to three weeks for build, training, and integration, and a structured rollout with you in the room.
What if it makes a mistake on a call?
Every call is transcribed and reviewed in week one. Mistakes are caught, root-caused, and fixed. After the first month, the rate of needed corrections drops sharply. We design clear escalation triggers from day one. If the agent isn't certain, it hands off, never improvises.
Can it work with our existing phone number?
Yes. We port your number or set up forwarding so the caller experience is unchanged. Same number, faster pickup.
Where is the data stored? Is it secure?
Your data lives in encrypted infrastructure in the region you choose. Transcripts and recordings are yours, exportable any time, and never used to train shared models. We can sign NDAs and DPAs as standard.
The process

Four steps.
Four to six weeks.
Then it runs.

We don't sell software. We build the agent, train it on your business, integrate it into your stack, and run it alongside your team. Here's how that actually goes, week by week.

01 · WEEK 1

Discovery

We sit with your team. Listen to a sample of real calls. Map the conversations that matter. Decide what the agent should and should not do. Output: a clear scope, a voice persona, a flow map.

02 · WEEKS 2–3

Build & train

We build the agent. Train it on your knowledge base, your pricing, your edge cases. Pick the voice. Hook in your CRM and calendar. You get a private test number to call yourself, as often as you want.

03 · WEEK 4

Soft launch

Live on 10–20% of calls. We watch every transcript in real time. Fix anything off. Add anything missing. By end of week, the agent is handling 100% of the calls it was designed for.

04 · ONGOING

Tune & grow

Weekly review of transcripts. Monthly performance report. Quarterly strategy. The agent gets sharper, the integrations get deeper, the load it carries grows. You scale without hiring.

What we need from you

A little input.
A lot of output.

Most clients give us maybe four hours of total time across the build. Two hours of discovery, an hour of review, an hour of approval. That's it.

We don't ask you to write scripts, learn AI tools, or manage anything. The point of Cortiva is that we run it. You see the results.

Under the hood, briefly

What runs your agent.

Cortiva is built on a custom orchestration layer that ties together best-in-class speech, language, and voice models. We pick the right tool for each job rather than locking you into one vendor.

Speech understanding

Custom-trained recognition for Indian and global languages. Handles accents, background noise, and code-switching mid-sentence.

Reasoning engine

We orchestrate multiple language models so the agent picks the right one for the right moment. Cheap models for simple replies, deep models for hard decisions.

Voice synthesis

Premium voices that pass for human in most contexts. Tuned for your brand: warm, formal, brisk, regional, whatever fits.

Your data, your control

Hosted in the region you choose. Transcripts and recordings exportable any time. Never used to train shared models. NDAs and DPAs as standard.

Where Cortiva lives

Built for the
businesses where every
call is revenue.

Cortiva works in five verticals where the cost of a missed call, a slow response, or a wrong answer is highest. If you're in one of these, we already speak your language. Literally.

Healthcare

Clinics & healthcare networks

Treatment pricing. Appointment booking. Pre-visit screening. Multilingual patient support. Round-the-clock coverage for clinics and chains that lose revenue every time the phone rings unanswered.

Real estate

Brokerages & developers

Inbound enquiries on listings. Site visit booking. Budget qualification. Re-engagement of cold leads. The agent that picks up at 11 PM is the one that closes the buyer your competitor missed.

Agritech

Farmer-facing operations

Crop advisory. Order placement. Logistics scheduling. Multilingual support for farmers across Hindi, Gujarati, Marathi, and regional languages. Built for businesses that serve rural India at scale.

Solar

Solar installers

Lead qualification. Site survey booking. Quote follow-up. Loan and subsidy queries. The agent qualifies prospects so your sales team only visits houses that will actually convert.

Services

High-call-volume SMBs

Salons, repair shops, restaurants, training institutes. Anywhere callers want quick answers about hours, pricing, availability, and bookings, and a missed call is a lost customer.

Custom

If you run inbound or outbound voice calls at any scale, there is a Cortiva build for you. Tell us your operation. We'll tell you, honestly, whether it's a fit.

Case study

Aurelia,
the agent that
doesn't sleep.

Aurelia is a multilingual voice agent we built for a luxury real estate brokerage in Mumbai. She handles inbound enquiries in Hindi, Marathi, and English, knows every active listing in the portfolio, qualifies budget, schedules site visits with the right agent, and routes complex deals to senior partners.

Within the first ninety days, after-hours response rate moved from 23% to 100%. Aurelia now generates roughly one in three confirmed site visits the brokerage runs each month.

The first conversation with the Cortiva team felt like talking to consultants who'd already run our operations for a year. They asked the questions we were afraid to ask ourselves.
