- Paper
Participated · Series A · Jul 2026
Paper offers a professional-grade design environment built for teams shipping software with AI and coding agents, combining agent-native workflows with a shared language for designers and engineers. Its Desktop product, launched in early 2026, turns the design canvas into a shared workspace for humans and AI agents, connecting design, code, and data in real time. Paper renders with HTML and CSS so designs can connect directly to production code and the agents that create it, aiming to reduce handoff friction and speed delivery from idea to production. The company reports ARR growth of 25x since the Paper Desktop launch and lists customers including Ramp, Lovable, Vercel, PostHog, Quartr and Y Combinator. Founder and CEO Stephen Haney leads the company as it expands its team and invests further in AI-native workflows and product development.

- 14.ai
Participated · Seed · Mar 2026
14.ai operates as a fully managed, AI-native customer support agency that combines proprietary software with human agents to take over an entire support function for startups. Its stack can be integrated within a day and monitors tickets across email, voice, chat, SMS, TikTok, Facebook, Telegram, WhatsApp and other channels, enabling the company to clear large backlogs in hours. Beyond resolving support issues, 14.ai captures early-stage customer conversations to generate revenue-growth insights for clients and aims to eliminate three cost centers—ticketing systems, AI add-ons, and human labor. Current customers span sectors such as luxury skin care (Yon-KA), smart glasses (Brilliant Labs), and lighting (Creative Lighting). The six-person team, led by co-founders Marie Schneegans and Michael Fester, plans to hire additional AI engineers over the next six months using newly raised capital. To refine its technology, the company also operates GloGlo, a glucose-gummies brand run largely by AI. Investors view the model as a flexible mix of AI and human support that can evolve as automation improves.

Led by CEO Ankur Goyal, the company plans to expand its engineering and go-to-market teams, grow its physical office footprint, and accelerate the rollout of new infrastructure products for production-grade AI.

- Quanta
Participated · Series A · Dec 2025
Quanta combines an automated accounting engine with an in-house accounting team to ingest transactions from banks, payroll, revenue, and spend systems and keep books continuously reconciled. Its newly launched Prism layer allows finance teams to query live, verified data and receive sourced, auditable answers to questions such as margin by product or changes in churn. By integrating automation with human oversight, Quanta reports that customers like Equals have cut close times by 85% and eliminated frequent discrepancies. The platform’s continuously maintained, trustworthy data set differentiates it from tools that sit atop legacy ledgers or outsourced bookkeeping. Prism adds an agentic AI interface that reasons over this clean data, turning static reports into an interactive intelligence layer. With its latest funding, Quanta plans to deepen its accounting engine, grow its expert services team, and accelerate Prism’s development, moving toward a fully live, traceable financial system for modern companies.
