Your CRM fires. A personalized video lands. You didn't touch it.
Fixed-price builds. No Zapier templates. No broken automations past 50 contacts.
You get a workflow map, an API cost projection, and an integration blueprint.
We integrate the tools your team already uses.
Video
CRM / Outreach
Automation
No Zapier templates. Direct API integration, with retry logic, rate-limit handling, and failure alerting on every connection.
How does a build work?
Four steps. You know the price before we write any code.
Audit
We map your current stack: your CRM, your video platform, where leads enter, and where the manual work piles up. You get a workflow map, an API cost projection, and an integration blueprint. Useful even if you never hire us.
Blueprint
We turn the audit into a scoped build plan: architecture, error handling, API budget, timeline, and one fixed price. No hourly meter.
Fixed-price build
We build the pipeline. The flagship Video Sales Engine takes 3-4 weeks. We build error handling into every webhook, so an API hiccup does not silently drop leads from your pipeline.
Retainer (optional)
APIs change and platforms update. Maintain ($997/mo) keeps your pipeline monitored and patched. Grow ($1,997/mo) adds new sequences each month. Or take the handover docs and run it yourself.
Is Kastiv a fit for your team?
This is for you if
- You lead sales, RevOps, or the whole company at a B2B SaaS or sales-led SMB
- You already pay for HeyGen or Synthesia seats, and they produce maybe 20 manual videos a month
- You run HubSpot or Salesforce, and video sits outside it
- You want: CRM trigger, personalized video, prospect inbox. Automated. Without touching it.
This is not for you if
- You want a $99/mo tool to do it all. That tool is the reason your current setup broke.
- You buy AI video for ad creative volume. We build outreach pipelines, not ads.
- You want coaching or tutorials to build it yourself. Start with our free HeyGen API Integration Guide instead.
Why not just use Zapier?
Zapier gets you to 20 videos a month.
Good for testing. Not for production.
- Breaks past 50 contacts
- No error handling - silent failures drop jobs
- Can't handle API auth refresh automatically
- You own the debugging when it stops working
The Engine runs at your full list.
Built for production volume from day one.
- Built for production volume - no contact ceiling
- Error handling on every webhook, with retry logic
- Automatic token refresh on every connection
- Working Pipeline Guarantee - we fix it if it breaks
If 20 videos a month covers your case, use Zapier and keep your money. If it doesn't, read the failure modes we documented before you decide.

Common questions.
How is this different from a Zapier template?
Zapier templates break past 50 contacts and have no error handling. We build production pipelines with retry logic, error handling on every webhook, and automatic token refresh. If it breaks post-launch, we fix it - that's the Working Pipeline Guarantee.
Do I need to already have HeyGen or Synthesia?
Yes. We wire your existing platform into your CRM. If you're evaluating which platform to buy first, we can advise during the audit - but we don't provide the platform license.
How long does a build take?
The Video Sales Engine takes 3-4 weeks from signed contract to a running pipeline. The audit is 1 week. We give you a fixed timeline before any money changes hands.
What CRMs do you integrate with?
HubSpot and Salesforce are the primary targets. Pipedrive and Apollo.io are available at additional scope. If you run something else, ask us in the audit - we'll tell you honestly whether it's feasible.
What happens if the pipeline breaks after handover?
The Working Pipeline Guarantee covers the scope we delivered. If something we built breaks within 30 days of handover, we fix it at no charge. After 30 days, our Maintain retainer ($997/mo) covers ongoing monitoring and patches.
What has Kastiv shipped?
Publishing products across Shopify, Meta, and Pinterest was a copy-paste job eating 8-12 hours a week.
Python automation bots connecting the Shopify product catalog to Meta and Pinterest APIs. Error handling on every call, so a failed token gets retried instead of silently dropping a post.
