Signable raises £5M from BGF to expand e-signature platform
Signable, a Bristol-based e-signature software platform, has secured a £5M investment from growth capital investor BGF to fuel product development and expansion across SME and mid-market segments.
Founded in 2012 by Olly Culverhouse , Signable provides businesses with a secure, compliant way to manage electronic signatures and digital workflows. It has grown organically, building a customer base across regulated and document-intensive sectors — serving organisations including Aardman, Krispy Kreme, and Smart Pension.
Edwin Davies and Hannah King led the deal for BGF.
The investment will support Signable's push into qualified electronic signatures — a more advanced standard that enables the platform to handle complex use cases in regulated sectors such as legal, property, and financial services.
"This investment allows us to build on the strong foundation we've created," Culverhouse said. "With BGF's support, we can invest further in our product, our people, and our commercial capabilities as we expand into new markets."
BGF will work with Signable's management team to strengthen the organisation, invest in commercial leadership, and scale partnerships and integrations.
The e-signature market is crowded. Signable competes against well-funded incumbents like DocuSign and Adobe Sign, which dominate enterprise adoption. Scaling from an SME-focused platform into mid-market segments means going head-to-head with players that have far deeper pockets and broader global reach.
Maintaining its reputation for transparent pricing and responsive support — qualities that differentiate it among smaller customers — could also prove harder as the company grows.
BGF's bet reflects a broader trend of investors backing vertical and compliance-focused software tools over generic platforms. As regulatory acceptance of electronic signatures increases across the UK and Europe, specialist providers that understand sector-specific requirements stand to gain.
"Signable is well-positioned to benefit from ongoing digitalisation and increasing regulatory acceptance of electronic signatures," said Edwin Davies, investor at BGF. "The business has built a strong market position among SMEs that prioritise simplicity, transparency and compliance."
The deal also underscores BGF's continued appetite for backing UK software companies at the growth stage — a segment of the market where founder-led businesses often struggle to find patient, culturally aligned capital.
