Common Questions

What's the main difference between Arrfounder and GrowJo?

Arrfounder is founder-centric (discover people, read their tweets, learn from their journeys) while GrowJo is company-centric (identify high-growth companies, get contact data, analyze metrics). Arrfounder focuses on social proof and community; GrowJo focuses on quantitative growth intelligence and B2B sales data.

Which platform has more companies/founders?

GrowJo tracks 10,000 fastest-growing companies. Arrfounder has 1,000+ founders and 1,500+ products. Different focus: GrowJo = companies with 15-1,000 employees; Arrfounder = individual founders at all stages (solo to established).

Which is better for investors?

Depends on your investment style. GrowJo is better for traditional due diligence (growth metrics, employee trends, funding data). Arrfounder is better for finding authentic founders with social proof and understanding their building in public journey. Many angel investors use Arrfounder to discover founders, then verify with traditional tools.

Which platform is better for networking with founders?

Arrfounder is significantly better for networking. It's built around the building in public community with Twitter/X integration, comprehensive founder profiles, tweets feed, and social features. GrowJo is a B2B intelligence tool without community features - it provides contact info but isn't designed for networking.

GrowJo provides executive emails and direct phone numbers as a paid feature - this is a core offering for sales and recruiting teams. Arrfounder provides links to founders' Twitter/X profiles where you can connect publicly, but doesn't offer private contact data.
