B2B SaaS might lack glitz and glamour — but investors still love the sector and its money-making potential.

Things have been somewhat on the up for the sector recently. A recent Sifted Pro briefing showed it outpacing its B2C cousin in recent years, with European funding dynamics revealing a distinctive trend in B2B versus B2C investment. In 2017, B2B ventures secured $1.60 for every dollar invested in B2C startups — that's since grown to $2.33 in 2023. B2B unicorn creation also grew at a quicker rate than their B2C counterparts for the first time in 2021 last year, and hasn’t looked back since.  

So, which companies are set to add to the B2B SaaS sector's clout in the coming years? Investors from Peak, Frontline Ventures, CapitalT and Visionaries Club share the non-portfolio startups on their watchlists.
