SmartUp case study · September 2026

Invest in Praktika. Don't Trust the Traction Slide.

Investment memo · seed round · deck as of January 2024

A seed deck landed on my desk as a case study. The question was simple: would I invest?

This is the detailed version of my answer. Everything here comes from the deck or from public sources. Where I estimate or interpret, I say so.

$296k
Revenue in December 2023
+40%
Growth per month (deck)
486k
Monthly active users
$2M
Ask. Goal: $6M ARR in a year

Praktika is an app for practising spoken English with an AI avatar as the tutor. It launched in March 2023 and is backed by 500 Global. The deck names no valuation.

Scorecard

TeamStrong
Seven years together in conversational AI. No consumer app before Praktika, but strong advisors.
MarketStrong
Online English learning grows 16% a year. Duolingo was worth about $9bn in early 2024, so exits exist.
ProductStrong
Goes after speaking anxiety instead of content. A hypothesis until I see retention.
TractionUnproven
Fast growth. But the revenue may be prepaid and the deck shows no retention.
MoatThin
The technology can be copied. They have distribution, a clear audience and speed.
DealOpen
No valuation in the deck. A company that can probably fund itself can choose its price.

How I see the company

What do they sell?

A safe place to speak.

People don't fail at English because content is missing. There is more free content than anyone can use. They fail because speaking in front of others is embarrassing, and tutors are expensive.

With an avatar you can make mistakes without feeling judged. It still feels real enough that you show up again.

For me the most important slide in the deck is not the traction slide. It is slide 12, where users call the avatar a friend. These are quotes the team picked, so I treat them as a first signal and not as proof.

Who pays?

The reviews shown in the deck are translated from Portuguese, Spanish and Russian. They come from Samsung, Xiaomi and realme phones.

I read that as Android users in emerging markets who need English for work. The deck itself names jobs and migration as what drives the market.

That matters for the price. These users don't compare Praktika to Duolingo. They compare it to a tutor, and the deck says Praktika is 50 times cheaper.

How do they grow?

One review mentions a 3-month plan, so I think most customers pay upfront.

That changes how the business works. If a customer costs less in ads than he pays on day one, the money is back immediately and can go into the next ads. Then it repeats.

This took them from launch in March 2023 to $296k a month in nine months, before this round.

What is the round for?

40% of the $2M goes into ads. That is $800k, or about $67k a month.

December alone brought in $296k. So the ad budget is less than a quarter of one year's revenue at December's pace. I don't know their costs, but they could probably pay for these ads themselves.

So I don't think this round is about survival. It buys speed.

The round next to one year of revenue

Ad budget (40% of the round)$0.8M
The whole round$2.0M
Revenue, 12 × December$3.56M
“12 × December” is a pace and not a result. Actual revenue in 2023 was roughly $1M, because the early months were small. But it is the fair comparison for money that will be spent over the coming year. Spread over twelve months, the $800k ad budget is $67k a month. That is less than a quarter of what December brought in.

The team

The CEO, Adam Turaev, and the CPO, Ilya Chernyakov, have been friends since seventh grade. They worked at Bosch and Sanofi and founded Cleverbots in 2017, a company that built chatbots and conversational AI for large companies. The CTO, Anton Marin, was co-founder and CTO there.

Cleverbots did over 60 AI projects for companies like Nestlé and AstraZeneca and made $2M in 2022. Both founders were on the Forbes Russia 30 Under 30 list in 2023.

What I like about this:

  • The founders already ran a company together for years. The risk that they fall apart is small.
  • They have worked on conversational AI since 2017. Praktika is not a reaction to the hype. It is the next step of what they already did.
  • They know how to earn money with little capital.

Their weak spot is that an agency is not a consumer app. Selling projects to Nestlé is a different job than keeping millions of users in an app.

They know this. Their advisors cover exactly that gap: the head of user acquisition at Flo, Adapty for subscriptions, and Ilya Gelfenbeyn, who founded Dialogflow and Inworld AI.

The potential

The market grows, and it moves online

Slide 2 shows English learning going from about $45bn in 2021 to about $80bn in 2030.

The online part grows fastest, 16% a year. It goes from about a fifth of the market to almost half. Duolingo made over $500M in 2023, so there is room for big companies here.

Even a cautious case is big

I don't think 40% a month will last. Nobody keeps that up for long.

With 10% a month they would still make about $930k a month in a year. That is roughly $11M ARR.

Their own goal is low

The deck's goal is $6M ARR. ARR is not the sum of a year. It is one month times twelve. So $6M ARR means a single month that brings $500k.

At 40% a month they reach that in seven weeks. At 10% it takes six months.

The goal only needs 4.5% a month. Then they would take in $296k × (1.045 + … + 1.045¹²), which is about $4.8M over the year, and end the year at $500k a month.

It also fits something else: today's run-rate (12 × December = $3.56M) plus the ad budget times three ($2.4M) is almost exactly $6M. That is my reading, not something the deck says. But if the goal was built like this, it means the founders only count growth that comes from ads.

When does a month bring $500k?

6 months

until a single month brings $500k. That is the deck's twelve-month goal.

$0k$250k$500k$750k$1.0MDec+3 mo+6 mo+9 mo+12 moGoal · $500k a month ($6M ARR)4.5% a month: what the goal needs
ARR is one month times twelve. So $6M ARR is reached as soon as a single month brings $500k. December already brought $296k. At the 40% a month from the traction slide that is seven weeks away. I don't think 40% will last, but even at 10% it takes six months. The dashed line shows the 4.5% a month that the goal really needs.

Pro

  • They solve the right problem. Companion apps keep users but earn little. Language apps earn money but lose users. Praktika could do both.
  • They probably don't depend on us. The $800k ad budget is less than a quarter of 12 × December revenue. Our money makes them faster.
  • Costs are falling. OpenAI cut the GPT-4 input price by two thirds in 2023, while subscription prices stayed the same.
  • The team has worked together for seven years and knows what it is missing.
  • The risk is limited. I can lose my investment once but win many times that.

Contra

  • The $296k may not be MRR. Slide 8 says MRR in the title and revenue under the number. If customers pay monthly, both are the same. If they prepaid for a year, the real monthly figure would be only about a quarter of that. The deck doesn't say which.
  • The 3:1 LTV/CAC is a forecast. Nine months after launch there is not enough history to measure how long customers stay. The deck shows no retention, no payback and no margin.
  • The growth may be bought. If customers don't stay, our money only speeds up a treadmill.
  • Others can build this: Duolingo Max, Speak, ChatGPT's voice mode.
  • “Top-5 language app in a year” does not fit a goal of $6M ARR. Duolingo made over $500M in 2023.

All of these are open questions, and the founders already have the data to answer them:

Is the revenue recurring?

If customers prepaid for months, December looks bigger than what really comes back every month.

TestThe bridge from $296k of revenue to MRR, after store fees, and the mix of plans.

Do customers stay?

The 3:1 only works if people renew. Nine months after launch nobody can know that yet.

TestRenewal by start month and plan, and how many paying users were active last month.

Is the growth bought?

40% of the round goes into ads. Growth that is bought stops when the spending stops.

TestCAC and payback by channel, the share of organic installs, and what happened to CAC when spend went up.

What do heavy users cost?

Speaking is unlimited and runs on paid AI models. The keenest learners may cost more than they pay.

TestGross margin per active learner, and for the top tenth by usage.

Can others copy it?

Duolingo Max, Speak and ChatGPT's voice mode can ship the same feature.

TestWhether users who stay with one avatar retain better. The history with a learner is what a copy starts without.

Decision

Invest

I would invest at a seed valuation. The pros are about what Praktika is. The contras are about things the deck doesn't show yet. They decide the price and what I check first. They don't change my answer.

I would walk away if

  1. 1fewer than about 30% of quarterly subscribers renew even once. Then a 3:1 LTV to CAC is hard to reach at realistic ad costs.
  2. 2it takes more than six months to earn back the cost of a customer after store fees and AI costs. With customers paying upfront it should be much faster.
  3. 3more than 30% of paying users didn't open the app in the last thirty days. That would be revenue from people who forgot to cancel.
  4. 4the IP and company structure from their previous firm, Cleverbots, are not clean.

What I would ask the founders first

  • Is the $6M goal simply today's run-rate plus your ad budget times three? What growth do you really expect?
  • What grows without ads?
  • You could probably pay for these ads yourselves. What does our money change?
  • How do you get from $296k of revenue to MRR, after store fees? What is the mix of plans?
  • Can I see renewal by start month and plan?

What happened after, kept out of the reasoning

I made my decision only with what the deck shows. Afterwards I looked up what happened.

This seems to be the $2.5M seed Praktika closed in early 2024. The 40% held for a while: revenue grew about 41% a month to roughly $20M annualised by May 2024, when they raised a Series A of $33–35M led by Blossom Capital.

In May 2025 the company reported more than 2 million monthly users, 14 million downloads and nine languages. There has been no new funding round since, and no new revenue figure. In the same time their competitor Speak passed $100M ARR.

So the seed worked out. The best case is still unproven, and retention has never been published. That was my open question in January 2024, and it still is.
