What is a CRM system?
CRM software for startups such as HubSpot are tools that help businesses manage interactions with current and potential customers.
LeanGTM helps founders to develop iterative and self learning engagements with their customers to better understand how to communicate their value to their target clients.
How startups benefit from sales and CRM solutions
The addition of K3C provides SeedLegals clients with access to specialist support for building sales strategies, auditing existing processes, and setting up regional sales management.
Clients will also be able to use K3C’s LeanGTM platform, which complements leading CRM systems like HubSpot by helping companies use AI to better understand their clients and run targeted specific and timely outreach programs.
James Clark, CEO of K3C:
“Our mission at K3C has always been to empower founders with the same level of GTM infrastructure & capability that global enterprises enjoy, without the overhead. Joining the SeedLegals marketplace, alongside HubSpot, accelerates our capacity to support more startups and further extends our work across Europe’s startup ecosystem.”
With the EU’s new Start-up & Scale-up strategy announced earlier this year, the SeedLegals and K3C partnership comes at a pivotal time for founders.
For SeedLegals, the collaboration is part of a broader effort to expand its marketplace with trusted growth partners offering services such as CRM software for startups. A company spokesperson explained:
Liliana Conrad, Head of Partnerships at SeedLegals:
“SeedLegals clients look to us not just for legal and funding support, but for trusted partners who can accelerate their path to growth. K3C brings deep expertise in go-to-market systems and strategy, making them a perfect complement to HubSpot in our Sales & CRM partner category.”
How GTM tools like K3C’s LeanGTM integrate with HubSpot for Startups
Startups who’ve already experienced the benefits of working with K3C say the partnership is a significant step forward. Sarah Montgomery, CEO of Infyos, shared her experience:
“We’ve worked with SeedLegals through various stages of our growth, as well as deploying HubSpot & working with K3C. Getting to a repeatable GTM process that scales our outreach while preserving founder time is a constant challenge of resource allocation.
“Working with a partner to help us with the challenges around data discovery development, enrichment and executing outreach as part of a process that provides us with data insights to improve the relevance and scale is one of the main reasons we chose K3C, we needed to move away from ad hoc moments of inspirational outreach to a systematic, structured, and measurable process across our whole team.”
K3C has also been preparing its own EIS funding round using SeedLegals’ platform, making it both a customer and a partner.
“This partnership is about more than commercial terms,” added James Clark. “It’s about investing in the European startup community, making sure founders have the tools, systems, and trusted partners to scale faster and more sustainably.”
