Grizz

Selling into construction usually means stitching together a project-lead service, a generic contact database, a tech lookup tool, spreadsheets and an outbound agency. None of them understand contractors. Grizz replaces all of it. Know every contractor. Every US and Canadian construction company, resolved to its real parent and classified by what it actually does: heavy civil, GC, mechanical, electrical and 22 more activity classes. Spot prevailing-wage and self-performing contractors that generic databases miss. See their tech stack. The ERP, project management, payroll, estimating and field software every contractor runs, with a confidence grade on every signal and the date they adopted it. Find who’s running legacy software and who’s switching right now. See their projects and partners. What each company builds, and the GCs, subs and owners they build it with. Find who works together and who can vouch for whom. Reach the right people. Owners, controllers, HR leaders, PMs and superintendents, with verified email and mobile, tied to their companies. Use it where you work. Syncs to HubSpot, Salesforce and Attio without duplicating your records. Build lists in plain English, find lookalikes of your best customers, or ask Grizz questions directly in Claude or ChatGPT. Or let us run it. Pay-per-meeting outbound, RevOps as a service and sales recruiting, from a GTM team that brings its own data.

Handhold

Handhold builds Holly, an AI agent that gives every buyer and new user the attention your best people would, inside your live product. Built for mid-market and enterprise B2B SaaS teams. On your website, Holly is an AI demo agent: discovery first, then a live product demo shaped around what each buyer needs, by chat or voice, in 50+ languages, any time of day. Good-fit leads reach your sales team with a summary and transcript. Inside your product, Holly is an AI onboarding agent. Each new user gets a path based on their role and goals, with a second cursor showing what to do, instead of the same tour as everyone else. We call this agent-led growth. Aikido runs its demos with Holly, Bolt uses Holly for in-product activation and Zuuvi for answering website visitors’ questions. Handhold syncs with Salesforce, HubSpot, Pipedrive and Slack, and most customers go live in about a week. GDPR compliant, with SOC2 in progress.
