Aqcelerator Research
Investment Thesis
Aqcelerator is the independent corporate venture capital arm of Aquafin, the Flemish wastewater utility that manages roughly 60% of household wastewater treatment in Belgium. Launched on 8 February 2024 as a new entity under the Aquafin banner, the fund exists to convert water-related challenges into climate-positive investment opportunities. Its stated mission combines capital with deep sector insight from Aquafin's decades of operational water-utility experience to help early-stage startups reach problem-solution fit, scale their technology, and build credibility in a niche, technically demanding market. Aqcelerator frames itself explicitly as a co-investor rather than a lead-driven fund: it prefers joining syndicates alongside experienced lead investors and contributing disciplined, impact-aligned governance, sector expertise (particularly in wastewater), and access to Aquafin's network of technical, strategic, and industry partners.
Sector Focus
The fund invests at the crossroads of watertech, cleantech, climatetech, and adjacent enabling technologies, with two internal strategic objectives: (1) unlocking common goods for reuse - treated wastewater, waste heat, and rainwater - and (2) stimulating market innovation more broadly across the water and environmental sector. Confirmed portfolio exposure spans sewer inspection robotics (MOVEX) and wastewater chemical-recovery/circular-economy technology (Metal Morph), indicating a thesis that reaches beyond pure treatment into adjacent industrial and robotics applications with a clear water or circular-economy anchor.
Stage Focus
Aqcelerator targets early-stage companies, explicitly spanning pre-seed through Series A. It looks for startups that can demonstrate either early market validation via pilots or defensible IP, and asks founders to define clear 12-18 month value-creation milestones alongside 2-3 measurable impact KPIs with baseline and target figures.
Check Size
Per the firm's own founder-facing materials, typical tickets run 50,000-200,000 EUR. This is consistent with a corporate-venture co-investor writing smaller checks alongside larger, dedicated lead investors, as seen in the Metal Morph round, where Aqcelerator participated alongside Sustainable Ventures, Green Angel Ventures, and Found Capital rather than leading.
Lead Tendency
Aqcelerator explicitly describes itself as following, not leading: the firm's own co-investor materials describe joining strong syndicates and following experienced lead investors. The one confirmed round found in research (Metal Morph, August 2026) was co-led by Sustainable Ventures and Green Angel Ventures, with Aqcelerator and Found Capital as participating investors, consistent with a follows lead tendency.
Recent Activity
- August 2026: Participated in Metal Morph's 700,000 GBP pre-seed round (co-led by Sustainable Ventures and Green Angel Ventures, with Found Capital also participating). Metal Morph is a UK (London-based) startup recovering aluminium- and iron-based coagulant chemicals from municipal and industrial wastewater for reuse, with early testing showing up to 90% chemical recovery and meaningful opex and emissions reductions.
- Aqcelerator is also a confirmed co-investor in MOVEX, a lightweight, modular sewer-inspection robot developed with Flemish (Aquafin) and Walloon (SPGE) wastewater authorities, along with CITV and Vault Engineering, designed to cut inspection costs by 60-70% versus traditional methods.
No information was found suggesting a fixed committed fund size (AUM) has been publicly disclosed; the firm's own co-investor page explicitly declines to disclose fund size, check-size ranges in aggregate, or portfolio company lists.
Portfolio Highlights
- Metal Morph (metalmorph.co.uk) - wastewater coagulant/metal recovery technology, pre-seed, August 2026.
- MOVEX (movex.be) - modular sewer-inspection robotics, co-developed with Aquafin/SPGE/CITV/Vault Engineering.
Both companies fit squarely within the firm's stated watertech/climatetech/circular-economy thesis and both reflect the follow-don't-lead co-investment pattern.
Team
- Maarten Raemdonck - Head of Innovation at Aquafin and Board Member / Investment Manager for Aquafin's corporate venturing division (Aqcelerator). Holds a Venture Capital & Private Equity certification (2024) and prior entrepreneurial experience as co-founder and CEO of Spencer. Active in the watertech investing community as an expert jury member for Tech Tour Water. Based in the Antwerp Metropolitan Area.
No additional named partners, principals, or investment staff were found in public sources; Aqcelerator's own team page does not list personnel, and its LinkedIn company page surfaces Maarten Raemdonck as the sole visible associated profile.
Decision Process
Not explicitly disclosed. Given the firm's structure as a small (2-10 employee) corporate venture arm embedded inside Aquafin, and the visible involvement of a single named investment lead (Maarten Raemdonck) reporting into Aquafin's broader Business Development & Innovation function, a lean or solo/small-committee decision process is likely, though this is inferred rather than confirmed.
Founder Preferences
Aqcelerator's own application criteria emphasize: founders demonstrating strong core capabilities and rapid learning ability with clear execution commitment; startups with early market validation (pilots) or defensible IP; and rounds structured to be co-investment-friendly, with visibility into who the other lead investor will be. The firm explicitly wants companies that can commit to measurable, milestone-based value creation over a 12-18 month horizon and can define concrete impact KPIs from the outset.
Geographic Focus
Headquartered at Dijkstraat 8, B-2630 Aartselaar, Belgium. While the firm is Belgium-based and its parent Aquafin operates within Belgium, its one confirmed investment (Metal Morph) is a UK company, indicating the fund's geographic scope for co-investment extends beyond Belgium into at least the broader European watertech ecosystem.
Uncertainties and Gaps
- No disclosed AUM or total fund size.
- No confirmed decision-making process, decision timeline, or typical involvement (board seat vs. observer vs. passive).
- Only one named team member could be confirmed; job title is inferred from combined LinkedIn/Org-chart/Crunchbase sources rather than a single authoritative bio page.
- Only two portfolio companies could be confirmed via public sources; the firm's own site does not publish a portfolio list.
