About

Serving Spotify, Snowflake, Zscaler, Anduril, and SentinelOne, Sublime is built on a detection-as-code philosophy using MQL (Message Query Language) for auditable, customizable detection rules. Founded in 2019 by Josh Kamdjou (10 years DoD and private sector red team, where phishing was consistently the fastest network access vector) and Ian Thiel.

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.
