About

SigmaOS is a productivity-focused web browser for macOS built around a workspace organization model — grouping tabs into workspaces by project or context rather than presenting an endless horizontal tab bar, with AI-powered features for summarizing pages, writing assistance, and research workflows built directly into the browser. Founded in 2021 in London and backed by Y Combinator, SigmaOS raised $4.12 million including a $4 million seed round led by LocalGlobe, targeting knowledge workers frustrated with traditional browsers' lack of workflow organization.\n\nSigmaOS's workspace model allows users to maintain separate browser environments for different projects (work, personal, research) with isolated tab groups, custom keyboard shortcuts, and split-view browsing. The browser's AI layer (powered by integrated LLM capabilities) enables in-browser text summarization, writing assistance, and research compilation without requiring external tools. The $10/month SigmaOS premium subscription unlocks advanced AI features, with approximately 30% of the 100,000+ user base subscribing as of 2024.\n\nIn 2025, SigmaOS competes in the productivity browser market with Arc Browser (Browser Company), Vivaldi, and Brave for users seeking alternatives to Chrome and Safari. The productivity browser category has grown as knowledge workers seek better tab management and AI-integrated research tools. Arc Browser's significant growth and funding has validated consumer appetite for redesigned browser experiences. SigmaOS's 2025 strategy focuses on expanding AI-powered browsing features, growing the macOS user base through workflow-focused content marketing, and potentially launching Windows support to access the larger non-Mac professional market.

About

Decimal is a Fishers, Indiana-based technology-enabled bookkeeping company that provides small businesses with a dedicated accounting team and a modern software platform for a flat monthly subscription. Founded in 2020, Decimal was built to address the most common frustration of small business owners who have outgrown DIY bookkeeping but find traditional bookkeeping firms slow, expensive, and opaque. Decimal pairs each client with a dedicated bookkeeper and accounting team who are supported by proprietary software that automates routine transaction processing, exception identification, and reporting, allowing the human team to focus on accuracy review, month-end close, and client communication rather than manual data entry.\n\nDecimal's product experience centers on transparency and responsiveness. Clients access their books through a web portal with real-time financial dashboards showing cash position, profit and loss, and accounts receivable and payable balances. The platform includes a communication thread for each question or task, giving small business owners visibility into the status of their bookkeeping without email chains or phone tag. Decimal's pricing model is a flat monthly subscription based on business complexity rather than hours worked, making costs predictable and removing the billing anxiety that characterizes traditional bookkeeping relationships.\n\nDecimal targets small businesses with $500,000 to $10 million in annual revenue that need accurate, timely books and periodic financial guidance but are not yet ready for a full-time accounting hire or a CFO-level engagement. The company operates as a fully remote team and serves clients across the United States in industries including professional services, e-commerce, retail, and service businesses. Decimal competes with Bench, Pilot, and Botkeeper in the technology-enabled bookkeeping market, differentiating on its dedicated team model, the quality of its software-plus-human integration, and its Midwestern operational roots that keep its cost structure competitive.
