Adeline Arts & Science has backed Capsa AI, joining their $18 million Series A co-led by TX Ventures and Pivot Investment Partners. Capsa turns a private capital firm's accumulated deal history and institutional knowledge into a live intelligence layer, surfacing insights and automating the critical workflows that matter most for investment teams. The round also saw participation from Bek Ventures and all existing institutional investors: Antler, Outward VC, Cornerstone VC and strategic angels. Here is why we invested.

The problem

Private capital firms collectively manage over $15 trillion in assets. It is one of the most information-intensive industries on earth,and much of this data is tracked across scattered spreadsheets, PDFs and emails. According to Capsa, investment professionals lose more than 500 hours a year to manual search and analysis, costing the industry an estimated $35bn annually.

The deeper problem is one of lost intelligence. Every IC memo, every diligence process, every market call represents accumulated judgment about how to evaluate opportunities. In most firms, that knowledge is effectively invisible: when a new deal arrives, teams start from scratch, unable to draw on the pattern recognition built over years of prior work.

AI has great potential to solve both of these problems, but generic AI tools were not built for the operational and regulatory realities of private capital. Investment teams operate under strict data governance requirements, confidentiality obligations, and compliance frameworks that demand purpose-built infrastructure. And the work itself is highly specialised: evaluating a leveraged buyout, stress-testing a capital structure, or synthesising a data room requires domain-specific reasoning that only improves when the underlying system innately understands the language, methodology, and standards of the industry.

Enter Capsa AI

Capsa is designed to meet that bar. The platform connects directly to the tools firms already use - CRM, Outlook, SharePoint, FactSet, PitchBook, DealCloud, and more - surfacing insights and experience from across a firm's history of deals, memos, and decisions. Every output is linked back to its source, so it is straightforward to audit, review and provide feedback at every level of the organisation.

The platform is built around the way PE and private credit teams actually operate — not off-the-shelf automation, but domain-specific workflows tailored to the firm, from sourcing and diligence through to IC materials and portfolio reporting. Trust, accuracy, and workflow fit are the design principles, not afterthoughts.

Why now

The industry has moved beyond experimentation. AI adoption in private capital is no longer confined to tech-savvy junior employees running shadow experiments. It is moving up the organisation, with senior decision-makers integrating it into their day-to-day workflows. Leaders have started to see and believe in the efficiency gains a well-designed AI workflow can deliver.

LP and capital allocator pressure is rising. There is growing pressure on GPs and investment firms to leverage AI effectively. It is becoming a strategic pillar - a source of competitive edge - not a back-office experiment.

The technology tailwinds are stronger than ever. Model costs and inference costs continue to fall. Model performance improves on a roughly six-month cycle. Context lengths keep expanding. Concerns around hallucination and reliability have reduced considerably. The technical and economic barriers that previously limited enterprise AI adoption are steadily disappearing.

Vertical AI is emerging across professional services. General-purpose foundational models created the mindset shift.  They showed professionals what AI can do and drove genuine behaviour change. But we see the next wave of value creation coming from products that go deeper into the critical workflows of specific industries. We have already seen category leaders emerge in adjacent professional services: Harvey and Legora have demonstrated the value of vertical AI built for professional workflows. Private equity and private credit have been waiting for their equivalent.

Best-in-class capital efficiency

One of the strongest signals for us was Capsa's capital efficiency. The company has grown 14x in ARR over twelve months, achieved entirely through founder-led go-to-market and zero paid acquisition. Growth at that pace, delivered that way, is a strong indicator that the product is solving a genuine pain point and has reached meaningful product-market fit.

Why this team wins

We always like to see founders who have lived the problem, and Danyal Oezduezenciler (CEO) has. He worked his way through the demanding early years of being a PE professional , and understands the dynamics of deal workflows and investment processes. He understands the precision required when outputs are reviewed by VPs, partners, ICs, and LPs and has built Capsa to that standard, with a focus on human-level accuracy. He brings attention to detail, persistence, drive, and high-performance expectations, combined with remarkably low ego.

Callum Downie (CTO) is a rare kind of founder: deeply technical and highly commercial, with a track record of zero-to-one journeys across multiple companies. He can speak equally well with engineers and with business users, processes trade-offs methodically, and is decisive in execution.

Jack Fisher (CRO) wrote the playbook for serving investment professionals. Ex-Pitchbook,  his decision to join Capsa is a huge testament to the value the product has already created. He brings enormous experience scaling products and commercial teams within the investment ecosystem - and is now applying that experience to Capsa and the age of AI.

Together, Danyal, Callum, and Jack are a force to be reckoned with - combining deep market understanding, technical execution, and go-to-market expertise.

The opportunity to build a category winner

The widespread adoption of foundational models for daily tasks has driven a significant behavioral shift and increased demand for workflow efficiency. Capsa capitalizes on this by building an operating system for private capital that deeply integrates into daily workflows. By combining a highly sticky workflow tool with both a top-down distribution advantage and proven bottom-up adoption, Capsa possesses the structural leverage needed to win in this market.
