Co-founders behind Reface and Prisma join hands to improve on-device model inference with Mirai

Much of the conversation around AI today is focused on building cloud capacity and massive data centers to run models. Companies like Apple and Qualcomm are in the early stages of making on-device AI more useful. Amid all that, the 14-person technical team of London-based Mirai is working to improve how models run on phones and laptops.

Mirai, which is backed by a $10 million seed round led by Uncork Capital, was founded by Dima Shvets and Alexey Moiseenkov last year. Both founders have experience in building scalable consumer apps. Shvets co-founded face-swapping app Reface, which was backed by a16z. Shvets later also became a scout for the venture firm. Moiseenkov was CEO and co-founder of the last decade’s viral AI filters app, Prisma.

As consumer developers, both had been thinking about AI and machine learning on devices even before generative AI became popular, Shvets said.

“When we met together in London, we started to chat about technology, and we realized that within the hype of GenAI and more AI adoption, everybody speaks about cloud, about servers, about AGI coming. But the missing piece is on-device [AI] for consumer hardware,” he told TechCrunch.

Shvets and Moiseenkov wanted to use AI to create a pipeline that would allow them to enable complex tasks on the phone, which led them to start Mirai. When they asked others who developed consumer apps, they heard that many wanted better cost optimization and margin per token usage, too.

Today, Mirai is developing a framework for models so they can perform better on devices. The company has built an inference engine for Apple Silicon that optimizes on-device throughput. With its upcoming SDK, developers can integrate the runtime in their apps with only a few lines, the company says.

“One of the visions why we started the company was that we wanted to give developers, like this Stripe-like, eight lines of code [integration] experience…you basically go to our platform, integrate the key, and start working with summarization, classification, or whatever your use case is,” Shvets said.

The startup built this engine in Rust, which can bump up a model’s generation speed by up to 37%, they claim. The company said that, while tuning the model for a platform, it doesn’t tinker with model weights to ensure there is no loss in quality of the output.

Mirai’s stack currently focuses on improving text and voice modalities on the platform, with plans to support vision in the future. The team has started to work with frontier model providers to tune their models for edge use and is in talks with different chipmakers. Later, it plans to bring its engine to Android, too.

In addition, Mirai aims to release on-device benchmarks so model makers can test on-device performance. Shvets recognizes that not all AI work can be done on-device, though. To enable a mixed mode of operation, the team is building an orchestration layer to send requests that can’t be fulfilled on the device up to the cloud.

While the startup is not directly working with apps just yet, its engine could power on-device assistants, transcribers, translators, and chat apps, we’re told.

Andy McLoughlin, managing partner at Uncork Capital, noted that he invested in an edge machine learning company in the last decade. He said that the company was early and eventually sold its business to Spotify. In today’s world, the situation is different, he thinks.

“Given the cost of cloud inference, something has to change… For now, VCs are happy to continue funding the rocket ship companies, spending inordinate sums on cloud inference. But that won’t last  —  at some point, people will focus on the underlying economics of these businesses and realize that something has to change,” he said. “It feels like every model maker will want to run part of their inference workloads at the edge, and Mirai feels very well-positioned to capture this demand.”

Mirai’s seed round also saw participation from individuals, including Dreamer CEO David Singleton, YC Partner Francois Chaubard, Snowflake co-founder Marcin Żukowski, ElevenLabs co-founder Mati Staniszewski, former Google AdSense product manager and Coinbase board member Gokul Rajaram, Groq investor Scooter Braun, Turing.com CTO Vijay Krishnan, Theory Forge Ventures’ Ben Parr and Matt Schlicht, and ex-Netflix technical leader Aditya Jami.

Reliance unveils $110B AI investment plan as India ramps up tech ambitions

Mukesh Ambani, the billionaire chairperson of Indian conglomerate Reliance, on Thursday unveiled the group’s ₹10 trillion (about $110 billion) plan to build AI computing infrastructure in India over the next seven years.

Speaking at the India AI Impact Summit in New Delhi on Thursday, Ambani said the investment would fund gigawatt-scale data centers, a nationwide edge computing network, and new AI services integrated with Reliance’s Jio telecom platform.

Reliance has already begun construction of multi-gigawatt data centers in Jamnagar, Gujarat, Ambani said, and more than 120 megawatts of capacity is expected to come online in the second half of 2026.

Ambani’s pledge adds to a growing wave of AI investment in India. Earlier this week, Adani Group outlined plans to invest about $100 billion to build AI data centers in the country, and the Indian government expects more than $200 billion in AI infrastructure spending over the next two years.

Global technology firms are also stepping up their presence, with OpenAI partnering with the Tata Group to develop about 100 megawatts of AI capacity in the country, and plans to scale that to 1 gigawatt eventually.

Ambani said the push is essential for India’s technological self-reliance, saying the country “cannot afford to rent intelligence,” and that Reliance aims to cut the cost of AI services as dramatically as it once reduced mobile data prices in the country.

“The biggest constraint in AI today is not talent or imagination,” Ambani said. “It is scarcity and high cost of compute.”

The build-out, Ambani said, would be supported by Reliance’s green energy capacity, which stretches to 10 gigawatts of surplus power from solar projects in Gujarat and Andhra Pradesh.

Reliance will partner with Indian enterprises, startups, and academic institutions to embed AI in industries ranging from manufacturing and logistics to agriculture, healthcare and financial services.

Jio has already been striking AI partnerships: it last year landed a deal with Google to offer free Gemini AI Pro access to millions of its users in India.

Reliance also plans to develop AI capabilities in several Indian languages to spur adoption of the tech, Ambani said.

The aggressive push highlights how India’s largest conglomerates are racing to secure a foothold in what is expected to be one of the country’s biggest technology opportunities.

This VC’s best advice for building a founding team

One of the most consequential decisions early-stage founders have to make is who they will bring on as their founding team. The first five to 10 employees will have a massive impact on the company culture, and the precedents set with them are difficult to change down the road. That’s why this season on Build Mode, we’re diving into what it takes to build a world-class founding team. 

To kick off season two, Isabelle Johannessen is joined by Yuri Sagalov, managing director at General Catalyst and former founder, YC partner, and seed investor at Wayfinder Ventures. Sagalov has worked with hundreds of pre-seed and seed-stage companies and has seen firsthand the best (and worst) ways to hire in the early days.

In this episode, Sagalov offers his best pieces of advice for founders who are hiring their first team, strategically building their cap table, and forming compensation structures that can scale with the company.

The three types of investors (and which one to avoid) 

Sagalov categorizes investors into three main buckets: the ones that are heavily involved and function as an extension of your team, the ones that will give you a check and then vanish, and the micromanagers. 

The first type of investor is the most valuable according to Sagalov: “They’re going to help you with recruiting, hiring, go to market. And the most interesting thing with those investors is often it’s completely disconnected from the check size.”

Although it may feel counterintuitive to turn down investments, working with VCs who will become overly involved in the process may cause more harm than good in the long run. Sagalov said, “The only bucket that I avoid is this third bucket of investors who give you money and they’re kind of in your kitchen, meddling. They have an opinion on everything. They get stressed out when things don’t go right.”

In a fundraise, everyone is putting their best foot forward, so Sagalov suggests reaching out to current portfolio companies before committing to an investor.  “The best thing you can do as a founder is actually talk to portfolio companies, talk to other founders that they’ve worked with, ask for concrete examples of how they’ve been helpful, if they’ve been helpful, and then actually ask how they were when things didn’t go right.”

How to split equity with a co-founder 

As an investor, Sagalov looks for co-founders who have created an equity split that is fair but also hedges for future misalignments. He suggests creating a slight differentiation by plus or minus one share so there is a clear way to break deadlocks. 

Sagalov also reminds early-stage founders that these early decisions have staying power: “Oftentimes founders over-index on ‘I came up with the idea, so I deserve the lion’s share.’  Most of the journey of the company is ahead of them. You don’t want someone waking up five years from now feeling like they put in equal blood, sweat, and tears but own one-fifth of the equity.”

Talk to early employees about risk and compensation 

The first few hires should be all in on the startup’s mission. Oftentimes, joining an early-stage startup can be perceived as risky. Sagalov emphasized the importance of discussing the risks and potential benefits: “Fundamentally, what you’re looking for when you’re hiring the first few people are missionaries who, beyond even the compensation, want to join you for the mission of the business,” he said. “You want to be honest with them that there is a lot of risk on the journey.”

Next week on Build Mode, we’re talking with Sarah Lucena, the founder and CEO of Mappa, who discusses how founders can take compatibility into account and hire the right fit for the team the first time, using their AI tool.

Freeform raises $67M Series B to scale up laser AI manufacturing 

Tech investors haven’t given up on the dream of making physical products with the same speed and ease as coding software. 

Executives at Freeform, a startup developing a novel 3D printing system for metal components, told TechCrunch that the company raised a $67 million Series B to expand its manufacturing platform. 

Investors include Apandion, AE Ventures, Founders Fund, Linse Capital, NVidia’s NVentures , Threshold Ventures, and Two Sigma Ventures. FreeForm declined to disclose the company’s post-financing valuation, which Pitchbook cites as $179 million.

CEO and cofounder Erik Palitsch said the funding would allow the company to upgrade its current GoldenEye printing system, which uses 18 lasers to fuse metal powders into precision components, to a new version. Dubbed Skyfall, the next iteration of the platform would use hundreds of lasers to produce thousands of kilograms of metal parts each day. 

That’s the culmination of a vision Palitsch launched in 2018 after developing rocket engines at SpaceX, where they found that industrial machines for printing metal components are expensive, finicky, and not well designed for mass manufacturing. 

Their new company would build its platform from the ground up to achieve higher throughput and flexibility, with an emphasis on active software controls. Palitsch says Freeform’s platform is “AI native,” noting a partnership with Nvidia that allows the company to access advanced GPUs.

“I think we’re the only quote-unquote manufacturing company out there that has H200 clusters in a data center on site,” Paltisch told TechCrunch. “What are they doing? We’re running real-time physics-based simulations and learning all the different aspects of the end to end manufacturing workflow.”

The data collected by sensors in the company’s manufacturing platform and during the simulations allows Freeform to rapidly improve production quality and quantity. 

“We have more meaningful data on the physics of the metal-printing process than any company in the world,” head of talent Cameron Kay said. 

While Palitsch said he could not disclose any customers, he said the company is already delivering hundreds of “mission-critical” parts to buyers. Now, the company wants to hire as many as 100 new employees and expand its facility to start executing on its contract backlog. 

Manufacturing-as-a-service has grown as a category as venture investors have taken a greater interest in building vehicles, robots, and energy production systems. For example, Hadrian recently earned a $1.6B valuation from its investors while developing automated production for defense, and VulcanForms and Divergent have raised hundreds of millions to develop metal-printing services of their own.

This piece has been updated to reflect former president Thomas Ronacher’s departure from Freeform.
