Who Is The Report Really For, You Or Your Client
Teamwork.com and Zoho Projects both track tasks and log hours, but they are built for opposite readers. One writes the story for the agency and the client paying the invoice; the other writes it for the team down the hall.
Billables AI
Billables AI is a San Francisco startup that runs quietly in the background of a lawyer's workday, watching the email, documents, calls, and calendar entries flow past, and turning them into finished, billable time entries - descriptions and all. Founded in 2023 by a team from SambaNova, Pinterest, and Mya Systems, the company argues that law firms lose real money not because lawyers do not work, but because they forget to write down that they did. It has raised roughly $14 million across a 2024 seed and a 2026 Series A, and now sells its passive, API-based timekeeping to hundreds of midmarket law firms.
Kourosh Zamani
Kourosh Zamani is the Co-Founder of Laurel, the AI-native time platform automating timesheet creation for professional services firms. Starting as Ping Inc. in 2016 alongside co-founder Ryan Alshak - a fraternity brother from UC Berkeley - Kourosh shepherded the company from bootstrapped startup through five funding rounds to a $100M Series C in June 2025, with investors including IVP, Google Ventures, Alexis Ohanian, and Kevin Weil (CPO at OpenAI). Before building Laurel, he ran VP of Business Development at Bailard Inc. and founded the Young Professionals of San Francisco, a non-profit that grew to 8,000+ members. His career arc from investment management to COO to Head of Sales to Strategic Partnerships lead mirrors the evolution of Laurel itself: from scrappy time-tracking app to a platform processing over $5B in gross market value for 100+ enterprise clients.
COR
COR is an AI-powered management platform built for creative and professional services firms — advertising agencies, consulting companies, law firms, and IT shops — that need to understand where their time actually goes and whether their projects are making money. By automating time tracking and layering on predictive analytics, COR gives agency leaders real-time visibility into project profitability, team capacity, and billing gaps before they become losses. Founded in 2017 in Silicon Valley by former agency operator Santi Bibiloni and co-founders Jose Gettas and Gabriel Marin, COR serves clients including Havas, Publicis, Ogilvy, Dentsu, and DDB across 35+ countries, with a reported $6.6M ARR and backing from investors including the founders of DoubleClick, Anaplan, MercadoLibre, and Krux.
Santi Bibiloni
Santi Bibiloni is the Co-Founder and CEO of COR, an AI-powered project profitability platform built for creative agencies, consulting firms, and professional services.

COR has raised ~$7.9M, grown 9% month-over-month, and counts Ogilvy, BBDO, and McCann among clients in 38 countries — backed by unicorn founders and the board member who built DoubleClick.
