Every Missed Call Is a Lost Customer. Renggo Answers in the Languages Big Platforms Skip.

This summer, Renggo was one founder and a platform he didn't fully trust yet. Sharofiddin Azizmatov had been building it alone, couldn't find customers, and felt his motivation slipping. So he brought in Abdurasul Abdurakhimov and Vita Reinberg. By autumn the three of them had changed who they sell to and what they promise. On 8 October their first paying client went live: an e-commerce business in Romania, answering customers in Romanian and English. On 17 October they signed their second.

How It Started

The founders started as frustrated customers.

"All of us have called a clinic where the doctors take forever to pick up, or tried to reach a notary or a builder, gave up and moved on to the next business on the list."

Every one of those calls is a customer the business never knew it lost. With Renggo the caller gets an answer right away, and the business keeps them.

Building From the Baltics

Renggo is an Estonian company, and that is why languages sit at the centre of it.

"Local languages like Estonian, Latvian and Lithuanian are rarely used for training models, so the market today is covered mostly in English and other widely used languages, and local customers get left behind."

The team sees that gap as a wide-open field. Renggo plans to keep training its own models on rare languages and to go where the corporate giants rarely look. Its first client, a Romanian e-commerce business served in Romanian, shows the same logic works well beyond the Baltics. The plan is to keep going after niche markets where the established US players have almost no presence.

How It Works

Think of Renggo as a receptionist that never sleeps. It talks to customers by phone, WhatsApp, Telegram and website chat, in many languages, rare ones included. It makes decisions within the flows the business defines and can act in the business's own systems, for example by making a booking. After every conversation it writes a summary, so the owner or anyone on the team can follow up the next day.

On top sits a business intelligence layer, something the team says is still new for this market. Renggo tells clients, without being asked, why customers call most often, what they want, when the busiest hours are and what is missing.

The typical customer is a clinic, a notary, a builder, or any small business where nobody can always pick up the phone. Once Renggo is running, lost callers stop being a problem, and the owner gets a clear view of where to grow.

Under the hood: voice-to-voice technology so conversations sound natural, with more in-house model training planned. Channels are phone, WhatsApp, Telegram and an embedded website chat, with email coming soon. It can plug in anywhere an API exists. A built-in quality-control loop scores conversations and feeds improvements back into the system.

The proof so far: a first paying client on 8 October, a second by 17 October, and three businesses in Uzbekistan finishing their free trials and looking to switch to paid plans.

The Hard Part

The low point was the summer. Building alone, with no customers and no full confidence that the platform was stable yet, Sharofiddin hit the point where motivation runs out. Bringing in Abdurasul and Vita changed the pace. Each now covers a different part of the business, with Abdurasul as CEO, Sharofiddin as CTO and Vita as Chief Strategy Officer, and both the platform and the customer conversations started moving much faster.

They also got the market wrong at first. They went in expecting the first big opportunity to be banks, insurance companies and call centres, with a pitch about cutting costs by replacing human operators. Both the customer and the pitch shifted. They moved to small and medium-sized businesses, where a pilot can start in days. The pitch changed with them:

"The stronger pitch turned out to be revenue, because every missed call is a lost customer."

The switch also gave them a much sharper picture of who they're building for.

What's Next

Right now Renggo is looking for its first major customers, and the pilots already running show how it performs in real businesses. In three years the team wants Renggo to be the receptionist every business can have: one that speaks dozens of languages, including the ones big platforms skip, and never sleeps.

The next chapter is scale. That means new markets and languages, better outbound conversations, and a bigger business intelligence side that helps clients understand their own customers.

Small and medium-sized businesses come first, but the longer-term plan includes enterprise. Large companies tend to hold back from third-party AI automation because the data they handle can't leave their own servers, and with today's providers that's virtually impossible. Renggo's answer is small in-house models built for a single market, such as an Estonian model that handles just three languages. A model that size can run on the customer's own servers, which gives them reasonable assurance that their data stays in-house.

The Toolbox, and Two Unlikely Teachers

The team's most underrated tool is Google Sheets. GitHub and Jira are non-negotiable for the platform itself, but everything built around the platform lives in spreadsheets: accounting, compliance, market research and metrics, the work that keeps a young company legal and alive through its first months. When you need to move fast, there's no point reinventing a base that already works.

Two of the founders also named someone worth learning from, and they couldn't be further apart.

Abdurasul picked Ingvar Kamprad, the founder of IKEA, whom he learned about while studying in Sweden. Kamprad didn't invent anything new. He looked at furniture, something everyone already bought, and asked why it had to be so expensive and complicated. He sees Renggo the same way:

"We're not the first to build chatbots, AI voice agents or tools that analyse customer data, and we don't pretend to be."

Most of those tools are built for large companies and sold as separate products. Small businesses either can't afford them or quietly accept the missed calls. Renggo's bet is to bring it all together simply enough that a small business can set it up, answer everyone, and learn from what its customers are asking.

Vita picked Marina Abramović's Rhythm 0 (1974). For six hours Abramović stood next to a table of 72 objects, a loaded pistol among them, and let the audience use any of them on her. People started gently and escalated, because nothing in the room stopped them and nobody was accountable to anybody. In the end a few visitors stepped in and took the gun away when it was pointed at her.

"When a system has no boundaries, the users end up drawing them, and not always well."

For an AI that talks to your customers and makes changes in your systems, that's the design brief. Vita builds the opposite of that room: clear boundaries, flows defined by the business, and a client who always knows what happens next and what doesn't.

How You Can Help

Renggo needs two things right now:

• Introductions to small businesses that miss calls. Clinics, notaries, builders, anyone where nobody can always pick up the phone. If you know an owner who'd try a pilot, connect them with the team.
• Native speakers of Estonian, Latvian, Lithuanian and Uzbek. Help train and test Renggo's models so the next small business gets answered in its own language. Two of the founders speak Uzbek, but they don't have the capacity to do it themselves.
