KFund's Miguel Arias & Acrobator's Joachim Laqueur in conversation with MiLaboratories's founder on the investor/founder dynamics

A deep dive into backing transformative technologies, navigating the seed-to-Series B journey, and how strategic investments in biotech and digital infrastructure drive innovation and global impact.

Welcome to a special episode of the EUVC podcast! This time, we’re experimenting with a new format where we bring together a founder and two of their key investors to uncover the dynamics behind building and scaling a venture-backed company.

In this episode, we’re joined by Stanislav Poslavsky, CEO and Co-Founder of MiLaboratories, a US-based biotech company founded in 2021. Focused on providing innovative solutions for genomic research, MiLaboratories operates on a B2B revenue model, catering to bioinformaticians and biologists in academic and pharmaceutical settings across the US, EU, and UK.

Joachim Laqueur, Founding Partner at Acrobator Ventures, a seed-stage investment firm with €28M in assets under management. Based in the Netherlands, Joachim specializes in backing global startups with a focus on Europe and the US, targeting B2B software and software-enabled hardware.

Miguel Arias, General Partner at KFund, €225M early growth fund, with €650M in assets under management. Based in Spain, Miguel focuses on Series A and B investments across Southern Europe and Latin America, targeting enabling technologies such as AI, IoT, and digital infrastructure.

Together, we explore how MiLaboratories secured its place in their portfolios, the process of building conviction across investment stages, and the unique challenges and opportunities of funding a biotech company in today’s landscape. Expect deep dives into deal-making dynamics, the art of company building, and even a few lighthearted moments that reveal the human side of venture capital.

Part 1: The Inception Story

Seed investor notes

  • Via an associate at Mubadala who knows Alexey while we were in DD with them.

  • We initially lost the lead to Speedinvest as they offered a more complete story as a health tech/bio tech investor

  • Asked Stan if he would be willing to extend the size of the round to accommodate us.

  • 3 RU visionary scientists, mission to keep the product free for academia, instrumental in the search for covid vaccine leads.

Founder notes

  • We were in an active fundraising process for our seed round; did around ~70 investor meetings within 2 month

  • The best talks with investors we got throughout our personal connections: both Speedinvest & Acrobator were intros from our friends. Cold outreach does not work!

  • We liked Acrobator very much, specifically for their speed in the decision making process and transparency. Also just personal feeling those are good people, who are investing in the team, not just in numbers

Series A investor notes

  • Connection via Speedinvest - Nadhila joined K Fund and knew the team through Andrea Zitna

  • Cross-pollination and access through colleagues

  • Starting operations in Spain - 15 Russians in Bilbao?

Founder notes

  • Active fundraising process, lots of meetings during 3 month; quite several very advanced convos with investors

  • This time the best intros we had were through SI & Acrobator

  • We really liked Kfund because of their business background: it was clear that they have something to bring apart from the financing


Initial impression (Founder’s view)

Founder notes

  • Given our profile and backgrounds, we always end up underselling what we build, unlike YC startups that have a talent to oversell

  • In general during the fundraising, on the first 10 meetings with various investors I was nervous, on the next 50 I was confident, and on the rest I was tired

  • Both at the seed and series a, Acrobator and Kfund entered when I was already quite confident and knew what to answer on VC questions

  • I always tried to feature the importance of the product that we are developing, and the fact the people use it for really cool and breakthrough stuff in the health industry; our customers and what they do with our software helps a lot to demonstrate this

  • But at the same time, it is challenging to explain in simple words (and within the limited time) what actually our users do with our software and what are their challenges. Simply because modern drug discovery combined with genomics is a so complex thing. I don’t like to oversimplify. Then it was not obvious for investors to see the financial potential of the company.

Seed investor notes

  • A product used all over the world in academic settings (and commercially without paying) - massive user base causing natural transition into business

  • Pharma giants turning to them for Covid

  • Visionary (what they can ultimately solve/remove the bottleneck for), passionate, very technical (this is the orange flag) - but love the Dexter’s Lab image

  • Democratisation of vaccine and other research - faster better personalized

Series A investor notes

  • More and more familiar with Bio-tech and Health/Pharma related businesses: IMU - Quibim both around precision medicine - We had looked extensively into Seqera in the past

  • Loved the “closing the gap” between Biologists and Bioinformaticians - Similarities to CARTO (democratize business users access to data and insights)

  • Loved the Open Source base and community with ties in the Academic world

  • A bit concerned about the team being too “scientist” and no focus on GTM

  • The deck picture of the team was funny, lots of work to do ;)

It improved a lot for the media announcement (Dimtry still with airpods😂)


Conviction-building

Seed investor notes

  • Conversations with expert users

  • Sarah - partner in 432 Legacy - 20y J&J

  • Data-moat + user base

Founder notes

  • Personal conversations with Joachim and the team, just good people, we felt synergy.

  • The key point was the term sheet.

  • Although, we decided to proceed with SI as the lead, we worked as much as we could to make a good room for Acrobator.

Series A investor notes

  • Conversation with experts in the field

  • Traveling to Bilbao and spending time with the team

  • Conversation with key customers and understanding their excitement

  • Key point was when we understood how big the TAM could become and the defensibility of the Block.s over time.

Founder notes

  • Personal conversations with Nadhi, Miguel and Sergio.

  • They did a really deep job in understanding our specific industry and our product, it was quite impressive

  • The key point was the term sheet

  • We had few good opportunities at the moment when we had to make the decision, so the speed of term sheet and the flexibility in negotiations from the Kfund side at that moment were really important


Behind-the-scenes anecdotes

Seed investor notes

  • Company visit in Montenegro

    • hardest to conceptually dumb down - happy to have Ramon by my side

Founder notes

BTW - and thats me working to make that office in Montenegro usable!!!


Series A investor notes

  • Raphael!!

  • Conversation with Dimitry C and how his blood is the most sequenced blood for any given person! This is the kind of weird we love

Founder notes

True 😅!! BTW I was on his concert last Sat in Bilbao, and my wife’s reportage even published on the main ru-speaking Raphaels’ fans club

Part 2: The Development Until Today

Biggest milestones

Seed investor notes

  • GTM development was always hard to convince to team of.

    • Nevertheless, a bunch of hard-core scientists were able to sell a command-line product to most of the big pharma and biotech players out there, get the FDA to see their solution as the only real baseline

    • It helps if the company is cash-efficient, though!

  • Time to really focus on ICP, positioning, marketing

Founder notes

  • When I first sold the license for ~$30k myself just on a call.

  • The second one is when we entered really big pharma and were able to sell there for more.

  • Launch of Platforma, so many efforts, so big product, but finally works and solves problems

  • Time to focus on GTM precisely

Series A investor notes

  • Strong tech/scientific arm - very weak GTM arm - How to improve

  • Define a clear ICP - where to fish and how?

  • Where are the low hanging fruits to get to the next milestone (current user base)

  • Define your nemesis & sharpen your market positioning (Dotmatics Geneious)

Founder notes

What Miguel mentioned, is our key focus and day/night job now.


Challenges and obstacles

Seed investor notes

  • Creating a situation where the company is comfortable sharing struggles and learn how to leverage their investors.

  • Visited Stan in Bilboa and had a lot of time to share my story over pinchos and wine.

Founder notes

  • I think relations definitely evolved over time and became more trustful and transparent

  • Learned that personal meetings are very important

Series A investor notes

  • Still honeymoon phase :), but lots of joint work in place: Hiring - Positioning - Customers intros - Sales tools -

  • Weekly meetings

Founder notes

  • Lots of work and very valuable contribution from the GTM/sales part

  • Procs/GTM/sales/ are things which are far from our deep-tech background, so we had some initial resistance against changes.

  • But now we see a great value


Lessons learned

Seed investor notes

  • More face-to-face time if we sense resistance

  • Pre-select a few coaches/mentors we believe the founder(s) connect to (neutral party)

Founder notes

Personal meetings are very important

Series A investor notes

  • VCs should try not to overwhelm the founders - at least do no harm - if you can help even better

  • Operating systems for startups are very important to ensure quick cadence - how universal is this for all kind of companies?

Founder notes

Identify where VC can help and really do not hesitate to use it and ask for help

Part 3: Looking Forward

Looking ahead

Seed investor notes

  • The public at large may never come to know the name MiLaboratories or Platforma, but it will benefit greatly.

  • The new software category they are creating is a game-changer as Miguel stated.

Founder notes

  • We are defining a new way of how R&D of top-notch therapies is done

  • The platform we are building is bigger than anything existing in the industry

Series A investor notes

  • Creating a whole new software category and empowering biologists with a platform to tackle lots of new discoveries: first immunology, but this goes way beyond.

  • Looking forward to see the academic community develop blocks and put them out there through Platforma. The possibilities are endless why beyond immunology, very exciting

Founder notes

I believe that in a couple years no new drugs will be discovered without our platform

Some things are made for platforms - music, cabs & pizzas. But fund solutions aren’t one of them. Their individual client focus and regulation-first approach is your guarantee for flexible solutions accommodative to a broad range of deal and client specifics. The kicker? Prices that match any of the shelf-products in the market.

✍🏻 EUVC Masterclass | Marketing & VC Fund Narrative

Your brand is everything. It’s what sets you apart, helps you win the best deals, attract LPs, and ultimately drive your growth. For emerging fund managers, building a credible brand and establishing the right marketing foundations early on are game-changers. Yet, many don’t know where to begin.

Your fund’s narrative is what makes the difference between an LP glancing at your deck or deciding they’re ready to write a check. It’s your brand that makes LPs feel confident they’re partnering with someone who knows how to make magic happen.

We’re planning a masterclass on building strong marketing foundations with a top industry leader. If enough people show interest, we’ll make it happen.
