Asperitas

Amsterdam-based single-phase immersion specialist with both passive natural-convection and active forced-convection systems — Europe's smallest-of-four immersion pure-play.

1. Core Product / Service

Asperitas is headquartered in Amsterdam and is the smallest of the four major immersion specialists (grc-cooling / liquidstack / submer / Asperitas) by funding and footprint. The product line is differentiated by two cooling topologies, both single-phase:

• Passive Natural Convection immersion — coolant moves through buoyancy alone, no pumps inside the tank. The original Asperitas IP — appealing for edge / remote sites where pump reliability is the failure mode.
• Active Direct Forced Convection immersion — pumped circulation for higher density compute — the newer line tuned to AI / HPC racks.
• AIC24 / Universal series — tank form factors.
• Coolant + monitoring subsystems.

In September 2025 Asperitas closed a new scale-up round led by STECON Group Global (Thailand) and Invest-NL (Dutch state-backed fund), with Shell Ventures and PDENH reinvesting [2][3][5]. The September round funds international expansion and continued development of both passive and active convection portfolios.

2. Target Users & Pain Points

• Edge / micro-DC operators — natural-convection systems' fan/pump-less reliability suits remote sites
• HPC and high-density compute — active-convection variant for >100 kW/rack
• Telcos and industrial customers — Asperitas has historic deployments in European telecom and industrial edge
• AI / GPU clusters — the UNICOM Engineering single-contract turnkey path announced February 2026 [partner press] is the channel-to-AI bet, mirroring what UNICOM also announced with grc-cooling

Pain solved: same immersion thesis as peers (chip-agnostic, low PUE, high density), with the passive-convection wedge as a unique reliability story for edge / lights-out operations where mechanical-failure exposure is the dealbreaker.

3. Competitive Landscape

Asperitas's edge: the only immersion specialist offering both pump-less passive and pumped active topologies in one product family. Smaller scale than peers but the passive option is a structural differentiator for edge and reliability-critical deployments.

4. Unique Observations

• Pure single-phase immersion play: no DLC product, no two-phase. Two topologies within single-phase: passive natural convection (no internal pumps) and active forced convection.
• NVIDIA / AMD / Intel reference design: not a public NVIDIA reference partner for the GB200/GB300 platforms (consistent with immersion peers). Reference design status remains a DLC-dominated lane (CoolIT / Vertiv / Boyd). Asperitas's AI go-to-market depends on partner channels (UNICOM Engineering turnkey systems, OEM integrations).
• Customer disclosure is thin: Asperitas hasn't named hyperscaler / neocloud customers publicly. Most disclosed deployments are European edge, telecom, and HPC sites. The UNICOM Engineering single-contract integration (announced Feb 2026, mirroring the GRC parallel deal in March 2026) is the explicit channel-to-AI play for 2026 — turnkey immersion-cooled AI compute as a single procurement.
• $/MW cooling capex share: with adoption still niche (<5% of new AI capacity), revenue attribution is small. Per-MW, full Asperitas immersion captures a similar slice as other immersion peers — ~$1.5-3.5M of the $3-6M cooling capex in a 1 MW AI build if it fully replaces chillers + DLC. The passive-convection systems also reduce ongoing opex by removing pumps as failure points — a TCO story, not just a capex story.
• Smallest of the European immersion pair: where submer has gone vertical into compute (InferX + Barcelona 56 MW DC) and raised ~$131M cumulative, Asperitas remains a pure cooling vendor. Funding amount for the September 2025 round was not disclosed [2][3][5] — typical of European strategic-investor rounds. Total cumulative raised is not publicly aggregated but is likely <$50M based on historical disclosures.
• Strategic-investor cap table: STECON Group Global (Thai industrial conglomerate, lead of the latest round), Invest-NL (Dutch state-backed fund), Shell Ventures (energy major / dielectric coolant supplier alignment), PDENH (regional Dutch development fund) [2][3][4]. Like grc-cooling's cap table (SK / ENEOS / Samsung), this is an industrial-strategic capital story, not a Sand Hill VC story.
• Sustainability and EU green-DC angle: heavy European ESG and sovereignty alignment — Invest-NL and PDENH back Asperitas because EU green-data-center capacity is policy-driven; Shell Ventures backs it for dielectric-fluid integration. This is a European version of the same industrial-investor playbook driving GRC in the US.

5. Financials / Funding

• Status: private; HQ Amsterdam; founded ~2017
• September 2025 round: led by STECON Group Global Private Limited + Invest-NL; existing shareholders Shell Ventures and PDENH reinvested; amount not disclosed [2][3][5]
• Total raised: not publicly aggregated; likely <$50M cumulative based on historical disclosures
• Revenue / ARR / customer count: not publicly disclosed
• Valuation: not publicly disclosed

6. People & Relationships

• Founded: ~2017 in Amsterdam (CEO has rotated since founding; check latest disclosures)
• HQ: Amsterdam, Netherlands
• Investors: STECON Group Global Private Limited (lead 2025), Invest-NL (lead 2025), Shell Ventures, PDENH (Participatiefonds Duurzame Economie Noord-Holland) [2][3][4]
• Channel partners: UNICOM Engineering (turnkey immersion-cooled AI / HPC compute single-contract, announced Feb 2026)
• Customers: European edge / telecom / HPC deployments — disclosures thin
• Strategic context: smallest survivor among the four major immersion specialists. If immersion stays niche, Asperitas plays the European sovereignty / edge / sustainability ESG card. If immersion scales for AI, the question is whether Asperitas catches the wave at its current scale or gets acquired into a larger industrial parent like its peers (liquidstack → Trane, motivair → Schneider).
