Planera have developed the first certified flushable and biodegradable sanitary pads that disperse quickly in water, and after a three-year R&D process, Planera has a flushability certification as well as VC backing in its pre-seed round from last year.

Square Mile, as their accounting partner, audited their assumptions used for their Innovate UK grant. Further, their financial assumptions have been used to build a three-way forecast (profit and loss, balance sheet, and cash flow) for Planera to determine how best to launch their business. Additionally, they intended to present it to potential investors to determine how much to raise and to add credibility to their story. They successfully raised £7.5m seed funding and an Innovate UK grant to launch their product. As a part-time FD (Financial Director), we will help plan and strategize for their product launch.
