How do their growth rates compare?

Apex has a month-over-month growth rate of -30.1%; SureThing has +21.1%.

How does pricing compare?

Apex: Contact for Pricing. Pricing is not published publicly. Apex routes visitors to a guided "Build my brain" onboarding and sign-in rather than a self-serve plan comparison, which implies consultative, contact-for-pricing packaging. Confirm current plan structure and seat limits directly with the team. SureThing: Freemium. Free to start with 150 credits refreshed every day, no credit card or sales call required. Paid plans start at $30/month for heavier usage, and subscribers who upgrade within 24 hours of signing up receive double credits for their first month.

Apex

A hosted second brain that gives every AI you use your business memory

Always-on business memory

Apex continuously ingests your email, calendar and calls and distills them into a structured, always-current knowledge base about clients, decisions and commitments — with no manual filing or tagging from you.

One brain, every AI assistant

The same memory layer plugs into the assistants you already use, including Claude, ChatGPT and Grok, so context follows you between tools instead of being rebuilt in every new chat.

Promise and follow-up tracking

Ask what you committed to this week and Apex answers with who, what, by when and the source — surfacing overdue promises before a client has to chase you.

Broad integration surface

The platform advertises 91+ connectors, covering Gmail, Google Calendar, Slack, Zoom, HubSpot, Drive, Notion, QuickBooks and more, so the memory is built from existing systems of record.

Strengths & Pros

+Genuinely infrastructure-shaped: it removes note-taking work rather than adding another app to maintain
+Memory is assistant-agnostic, so you are not locked into a single AI vendor for retrieval
+Proactive promise tracking targets a real, expensive failure mode for small firms
