Allset

Kyiv, Ukraine · Startup

Overview: Allset is a food-tech startup that provides a platform for online restaurant ordering and pickup. Originally launched as a dine-in pre-ordering app, Allset allows customers to pre-order meals at restaurants so that the food is ready at a scheduled time and they can "skip the line". Over time, Allset expanded to enable standard takeout orders, curbside pickups, and even contactless dine-in where you arrive and your meal is served immediately. The convenience factor is central: Allset's app lets users browse menus of partner restaurants, pay in advance (including tip), and streamline the eating experience without waiting. For restaurants, Allset offers a marketplace to attract busy professionals and on-the-go diners, while avoiding the high fees of delivery services. By focusing on pickup and in-restaurant efficiency, Allset positioned itself as a lower-cost alternative to delivery apps for eateries, promising no couriers or delivery logistics - just seamless pickup transactions. As of 2021, Allset had thousands of restaurant partners, particularly in major U.S. cities, and had broadened its use-case to also support contactless dining during the COVID-19 pandemic. Founding Story (2015): Allset was founded in 2015 by two Ukrainians, Stas Matviyenko (Stan) and Anna Polishchuk, who moved to California to grow the business. The founders previously built a mobile payments startup in Ukraine (Settle), which gave them insight into restaurant payment pain points. They noticed that busy professionals often have limited lunch break time and that waiting for service at restaurants ate up much of it. Thus, Allset was conceived to let users pre-order and pre-pay for meals so they could "set" everything in advance and have all set when they arrive (hence the name). The concept started with a few restaurants in San Francisco and New York participating. Early growth was modest as it required signing up restaurants one-by-one and changing consumer habits. However, by offering a win-win - restaurants get more turnover at lunch with guaranteed orders, customers get time savings - Allset steadily gained traction. Matviyenko and Polishchuk leveraged their Ukrainian tech team to build the app cost-effectively. In 2016, they got into the 500 Startups accelerator, which provided seed funding and mentorship in Silicon Valley. By 2017-2018, Allset expanded to multiple U.S. cities and refined its model to also include standard takeout ordering. Product and Market: Allset's target users were urban professionals and corporate employees looking for efficient lunch options. It integrated with over 7,000 restaurants in the U.S. and also some in Ukraine by 2023. Cuisine-wise it was diverse - from fast-casual chains to local eateries. The platform's business model charges restaurants a commission per order, but it touted itself as having significantly lower fees than delivery apps like UberEats or DoorDash. This is because pickup orders do not involve logistics costs. Allset also at times charged consumers small convenience fees or offered a subscription for zero fees. Its competition includes not just the big delivery apps, but also restaurant reservation systems and point-of-sale providers who have added mobile ordering. However, Allset carved a niche in "order ahead for dine-in/pickup." During COVID-19, Allset quickly shifted focus to contactless pickup and curbside service, which aligned with public health needs. The app usage grew as more consumers opted for takeout and avoiding crowds. Post-pandemic, Allset continued to be relevant as many users, accustomed to mobile ordering, kept using it for efficiency. Traction: By the early 2020s, Allset had facilitated tens of millions of orders. It was particularly popular in cities like New York, Los Angeles, Chicago, and Houston. The app had over 2 million users and a strong repeat usage among its core demographic (e.g., office workers who would use it daily for lunch). Allset's restaurant network grew to include national chains as well as local favorites. A reported figure from around 2021 indicated nearly 7,000 restaurant partners across the US and Ukraine, illustrating its significant network. Partnerships with large chains (for example, they onboarded Panera Bread in some regions) helped validate the concept. In terms of scale, Allset's gross merchandise volume (the total value of orders through the platform) reached eight figures in USD annually. Press coverage often highlighted Allset as a rising star in the on-demand dining space, and it received awards like being listed in Forbes' 30 Under 30 (Matviyenko was honored in 2018). Funding and Investors: Allset attracted a mix of Silicon Valley and Ukrainian investors through its journey. Early on, it raised a $3.35M combined seed (including a $1M pre-seed from SMRK, a Ukrainian VC). In 2018, Allset secured an $8.25M Series A, with investors like Greycroft, Andreessen Horowitz (a16z), VK (Digital Garage), and SMRK participating. This round helped fuel its expansion to new cities. By 2020, Allset had raised a total of about $16.6M in funding. A notable investor, Andreessen Horowitz, gave credibility given their prominence. Additionally, the EBRD (European Bank for Reconstruction and Development) co-invested in Allset, a nod to its Ukrainian roots and growth potential. The company was relatively capital-efficient, using a distributed team in Kyiv for development while its sales team signed restaurants in the U.S. According to PitchBook, Allset's valuation was healthy, though it never reached unicorn status. Acquisition by SoundHound (2024): A major milestone came in June 2024, when SoundHound AI, a Nasdaq-listed voice AI company, announced it had acquired Allset. The deal amount was undisclosed, but it marked a successful exit for the founders and investors. SoundHound's interest was in combining Allset's marketplace and restaurant partnerships with SoundHound's voice assistant tech for ordering (they have a voice ordering system used by restaurants). Through this acquisition, Allset's team (Matviyenko and Polishchuk) and technology joined SoundHound, aiming to power voice-enabled food ordering across SoundHound's large client network. The acquisition can be seen as a strategic fit: Allset brings the restaurant relationships and order workflow, while SoundHound brings cutting-edge voice AI. Allset's co-founders took on roles within SoundHound's leadership to continue growing this combined vision. For the Ukrainian startup scene, Allset's acquisition was a proud moment - a startup founded by Ukrainians achieved a notable exit on the global stage. Achievements and Impact: Allset's journey demonstrated the strength of Ukrainian entrepreneurs in the global arena of food tech. The company managed to enter the ultra-competitive U.S. food app market and carve a space for itself. It was recognized as one of Ukraine's top startups in multiple rankings. The company's growth also had a direct impact: it provided business to restaurants (especially small ones) by bringing them customers who might not have come in otherwise. Its focus on reducing wait times resonated with modern consumers' demand for convenience. Notably, Allset survived and adapted through the pandemic - offering features like dine-in ordering via QR code to minimize contact. This nimbleness likely made it an attractive acquisition target. Allset also set an example of transatlantic collaboration: R&D in Ukraine, business development in the U.S., which is a model other Ukrainian startups have since followed. Post-acquisition, the Allset app and brand continue to operate, now with the backing of SoundHound. With voice technology integration, a future use case might be ordering meals by simply speaking to your car or smart device, which could be the next level of convenience Allset helps enable. For Anna Polishchuk and Stas Matviyenko, their success with Allset has cemented them as influential figures in Ukraine's startup community, often mentoring younger founders and investing in new startups.

BlaBlaCar

Paris, France · Startup

BlaBlaCar is the world’s leading long-distance carpooling platform, often hailed as France’s flagship startup success. Founded in 2006 by Frédéric Mazzella (along with Francis Nappez and Nicolas Brusson), BlaBlaCar was born from Mazzella’s realization that countless car journeys had empty seats. The platform (named after users’ self-described chattyness level – “Bla”, “BlaBla”, or “BlaBlaBla”) connects drivers with spare seats to passengers traveling the same way, so they can share the ride and costs. Today, BlaBlaCar has a 100 million-member community across 22+ countries, serving over 25 million travelers per quarter pre-pandemic. It operates in most of Europe and parts of Latin America and Asia, having successfully localized carpooling in markets like Germany, Russia, Brazil, and Turkey. The company also branched into bus travel: in 2018, BlaBlaCar acquired Ouibus from SNCF, rebranding it BlaBlaBus, to offer intercity bus routes alongside carpool rides. BlaBlaCar’s business model charges a roughly 10–20% booking fee from passengers in mature markets, though in new markets it often launches free to build liquidity. Known for its strong community culture, BlaBlaCar emphasizes trust – it introduced verified profiles, ratings, and even an optional “Ladies Only” carpool option. The company achieved unicorn status in 2015 when it raised $200 million at a $1.6 billion valuation and later was valued around $2 billion. Despite the pandemic’s impact on travel, BlaBlaCar rebounded by 2022, even reporting profitability. In 2023, it raised €100 million in financing to fuel growth. BlaBlaCar is often cited in case studies (Harvard, etc.) as a pioneer of the sharing economy in Europe, proving that a people-powered platform can transform intercity transport. By bringing cost-effective travel to millions and fostering new friendships on the road, BlaBlaCar has truly brought “ridesharing” into the mainstream – and stands as one of Europe’s few consumer-tech unicorns with global reach.

Celonis

Munich, Germany · Startup

Celonis is a Munich and New York-based enterprise software company that pioneered the field of process mining – technology that analyzes a company’s IT event logs to visualize and optimize its business processes. Founded in 2011 by three friends (Alexander Rinke, Bastian Nominacher, and Martin Klenk) out of university in Munich, Celonis bootstrapped in its early years and landed Siemens as a key pilot customer for its process analytics tool. The software proved invaluable in identifying inefficiencies in processes like order-to-cash, procurement, and inventory management. By 2015 Celonis was the leader in this niche, and it partnered with SAP which resold Celonis as SAP Process Mining by Celonis. Venture capital soon followed: Celonis raised $27.5M in 2016 (Series A) then $50M in 2018 (Series B). Its growth was massive – from €1M ARR in 2012 to well over €100M by late 2010s. In 2019, Celonis raised $290M at a $2.5B valuation, making it a unicorn. It wasn’t done: by June 2021, Celonis announced a $1B Series D round valuing it at $11 billion, one of Europe’s largest software funding rounds. And in 2022, Celonis reportedly reached a $13B+ valuation, firmly cementing it among Europe’s most valuable private tech companies. The company’s product evolved into the Celonis Execution Management System (EMS), which not only discovers processes but also suggests and implements improvements (sometimes via RPA bots or triggering workflows). Celonis counts thousands of enterprise customers – including Siemens, BMW, Coca-Cola, Uber – and its software helps them save billions by cutting throughput times, reducing errors, and optimizing resource use. With dual HQs in Munich and New York, Celonis has aggressively expanded in the U.S., competing with companies like IBM’s process mining. The firm is also eyeing an IPO; CEO Rinke has mentioned that Celonis is positioning itself for a public listing when market conditions are right. In the meantime, Celonis keeps growing (estimated $400M+ ARR in 2023) and acquiring smaller tech startups to bolster its platform. Celonis epitomizes the success of enterprise software from Europe – deeply technical, essentially creating a new category, and achieving decacorn status within a decade.
