Which Buyers Has Castellum Chosen to Target?
Castellum Company targets high-credit B2B tenants: public sector entities, finance/tech/professional services in prime offices, and logistics/e – commerce operators in growth corridors.
Public sector tenants supply stability and account for approximately 23 percent of rental income by 2025, offering recession-resistant cash flows and high credit quality that anchor Castellum go-to-market strategy and reduce portfolio volatility.
Castellum GTM strategy focuses on finance, technology, and professional services firms that demand ESG-certified, prime workplaces; offices represent 55 percent of portfolio value as of fiscal 2025, so winning these tenants drives rent premium and retention.
Logistics and e – commerce tenants occupy roughly 30 percent of total portfolio area by 2025; Castellum targets growth corridors to capture rising demand for last – mile fulfilment and higher throughput per sqm.
Mixing public sector, ESG-focused corporates, and logistics hedges sector risk, supports occupancy above market, and leverages Castellum go-to-market plan where 95 percent of office space was environmentally certified by early 2025 to meet tenant carbon-reporting mandates; see Business Case History of Castellum Company for context.

How Does Castellum's Go-to-Market System Reach Them?
Castellum Company's go-to-market system reaches buyers through a mix of direct enterprise leasing by regional vertical pods, strategic global brokerage partnerships, and a digital leasing portal that treats discovery like e-commerce. Acquisition routes combine high-touch relationship selling, digital self-service (3D tours, real-time availability), and swing-space conversions to feed long-term leases.
Regional pods specialize in life sciences, tech, and public administration to shorten sales cycles and close larger leases faster. Direct leasing remains the core of the Castellum go-to-market strategy and accounts for the majority of new institutional lease volume.
3D virtual tours, real-time availability, and online booking make property discovery feel like e-commerce, increasing lead conversion and lowering time-to-visit for prospects. Online tools support Castellum GTM strategy by scaling initial touchpoints.
Strategic partnerships with global brokerages including JLL, CBRE, and Newsec capture international demand and major corporate relocations, routing large RFPs and multi-market requirements into Castellum's pipeline.
After divesting United Spaces in 2025, Castellum retained flexible short-term swing-space to convert occupiers into long-term institutional leases, improving customer acquisition strategy by lowering initial commitment friction.
Targeted outreach to sector decision-makers, account-based marketing, and brokerage co-marketing drives high-quality leads; digital ads and portal SEO amplify reach for transactional inquiries in key markets.
Sales enablement tools, CRM segmentation, and real-time availability data improve conversion rates and shorten cycles; reported internal metrics show submarket pod teams reduce average sales cycle by up to 20% in targeted verticals.
The strongest reach advantage is the blended model: high-touch enterprise teams plus a scalable digital leasing portal and brokerage network, enabling capture of both local B2B demand and international relocations.
Key mechanics of how the Castellum go-to-market plan reaches buyers emphasize direct vertical-aligned sales, brokerage partnerships, and digital-first discovery to convert short-term occupiers into institutional tenants.
Castellum GTM strategy reaches buyers by funneling high-intent corporate demand through regional pods and global broker networks, then converting via a digital leasing experience and flexible swing-space options.
- Direct enterprise leasing through regional vertical pods
- Digital leasing portal with 3D tours and real-time availability
- Account-based outreach and broker co-marketing for demand generation
- Blended model (enterprise teams + portal + broker partners) as the scalable reach advantage

How Does Castellum Convert Interest into Economic Value?
Castellum Company converts tenant interest into economic value by shifting leases into service partnerships and monetizing through index-linked rents and active asset recycling. The sales model blends direct leasing, sustainability-driven premiums, and portfolio optimization to turn attention into predictable rental and capital gains.
Castellum go-to-market strategy centers on direct enterprise-style leasing to corporates and public tenants, converting passive tenants into service partners via value-engineering and operational SLAs.
Leases are typically CPI-linked (index-linked), historically delivering rental uplifts in the high single digits; green leases permit premiums tied to energy KPIs, adding recurring rental yield and utility pass-throughs.
Energy-efficiency KPIs (target below 100 kWh/sq. m./yr), green leases, and service-level commitments increase tenant willingness-to-pay and reduce vacancy days, driving faster lease-up and higher Net Operating Income.
Castellum GTM strategy emphasizes renewals and upsells through sustainability upgrades and facility services; proceeds from divesting non-core assets are recycled into metropolitan assets to increase rental yield and drive repeat cash returns.
Economic mechanics: index-linked rent growth plus operational premiums lift NOI; active pruning recycles capital into higher-yield urban assets; combined these support the 2025 target: 10 percent return on equity over an economic cycle.

What Does Castellum's Commercial Model Suggest About Strategic Effectiveness?
The Castellum go-to-market strategy signals a shift from aggressive expansion to disciplined capital preservation, focusing on stable cash returns and operational efficiency. The commercial model shows scalable leasing operations but requires vacancy stabilization to sustain asset valuations and shareholder returns.
Targeting large corporate tenants and public-sector leases preserves cash flow stability and drives predictable income, supporting Castellum go-to-market strategy effectiveness.
Returning at least 25 percent of property management income via SEK 1.2 billion buybacks in 2026 improves per-share economics and signals confidence in recurring cash flow.
Economic occupancy fell to 89.8 percent by end-2025, creating a key trade-off: capital returns now depend on reversing vacancy-driven valuation declines.
With a loan-to-value ratio of 36.5 percent, below the 40 percent ceiling, the model looks defensible but hinges on the back-to-basics leasing pivot to restore asset values after a SEK 2.5 billion portfolio value decline in 2025.
The commercial model suggests strategic effectiveness is contingent: strong cash mechanics and a prudent balance sheet support shareholder returns, while operational focus must fix occupancy and demand alignment.
Castellum GTM strategy shows disciplined capital allocation and scalable leasing operations, but strategic success in 2025/2026 depends on reducing vacancy and restoring valuations.
- Corporate and public-sector leasing is the strongest buyer/channel choice
- Share buybacks funded by property management income are the clearest conversion strength
- Declining economic occupancy (89.8 percent) is the main weakness or trade-off
- Overall, the model is effective financially but operationally contingent on vacancy recovery
