About Us
F1F9 is a powerful combination of people working in partnership with clients to make the process of financial modelling more personal, more fit-for-purpose and helping everyone to achieve the best results.
History
F1F9 is a specialist provider of financial modelling and spreadsheet support services.
Established in 1999, we provide a hands-on approach that delivers tailored solutions, builds relationships and maximises confidence for clients around the world. In 2005, we set up the world’s first offshore modelling team (in New Delhi), now one the most affordable, high quality, modelling support resources available.
Our business has at its heart the FAST Standard: a uniquely transparent, efficient, maintainable and comprehensive spreadsheet modelling methodology.
Expertise
Our model build team includes experienced spreadsheet engineers who work directly with our clients. They have an equally important coaching role within the team: making sure that everyone, regardless of their role, is working with the same set of disciplines and approaches. The result is collaborative working with a clear understanding of the relationship between the requirements of an assignment and the spreadsheet solution that will best meet them. We work productively and efficiently with methods that are well documented and standardised.
Our lead instructors are senior professionals: highly adept technically and easy to learn from in the classroom. They teach what is practised in our model build team, sharing the knowledge as generously as possible.
