Cofounder is an operating system for your entire company. AI SDR tools (Regie.ai, AiSDR) specialize in outbound - and work beside Cofounder, not instead of it.
Complementary toolsYou do not have to choose only one. An AI SDR books meetings. Cofounder runs the business those meetings feed. An SDR tool does not incorporate your company, take payments, or run support. Use Regie.ai or AiSDR for pipeline volume while Cofounder owns company context, departments, and review.
Outbound specialists pair with the company OS instead of replacing it. Cofounder is $120/month for the company OS.
Relationship
Complementary. Cofounder runs the company; an AI SDR can sit beside it for outbound volume.
Specialist outbound. Not competing to own formation, support, finance, or the full company agenda.
Best fit
Founders who need a company operating system and may still want a dedicated outbound engine.
Teams that need prospecting and outreach volume from an AI SDR.
Core promise
An agentic company operating system for design, launch, growth, and operations with founder control.
Point tools that book meetings and run sequences, without owning the rest of the company.
What each owns
Company context, departments, review paths, and work beyond outbound - including marketing, ops, and support.
Outbound wedge: lists, sequences, replies, meetings. Neither incorporates your company or runs full ops.
Pricing
Company operator at $120/month. See live plans on the pricing page.
Priced as SDR or outbound tools. Pair with Cofounder rather than treating either as a full stack alone. Verify billing.
How they work together
Use Cofounder as the OS for the business. Plug an AI SDR when outbound volume needs a specialist.
Use the SDR for pipeline horsepower while Cofounder runs most of the company around those leads.
Regie.ai and AiSDR are outbound specialists. Run them while Cofounder operates the company - they are not Cofounder replacements.
Regie.ai
Runs the company around pipeline: positioning, ops, support, finance, and founder-reviewed work.
AI sales / outbound focus. Built for pipeline motions - a strong tandem tool beside Cofounder, not a company OS replacement.
AiSDR
Keeps SDR work as one motion inside a broader operator instead of letting outbound become the whole product story.
AI SDR automation for prospecting and outreach. Narrow on purpose: leads, not incorporation, payments, or multi-department ops.
Not as a pure SDR replacement. Cofounder runs the company. An AI SDR is a specialist for outbound. Many founders use both: Cofounder as the OS, plus an SDR tool for pipeline volume.
You usually do not have to pick only one. Use Cofounder to run the business. Add Regie.ai, AiSDR, or similar when you need outbound horsepower.
They do not incorporate your company, take payments, run support, or know the context of your business the way a company OS does. They book meetings and run sequences.
Cofounder is $120/month for the company OS. SDR tools have their own seats and usage. Pay for the outbound specialist only if that wedge is worth it on top of the OS. Check each vendor's billing.
No. Marketing sits inside Cofounder as company work. AI SDR tools stay specialists for outbound, and they pair with the company operator instead of replacing it.
Use Regie.ai or AiSDR when outbound volume is the job. Use Cofounder as the operating system for company work at $120/month.
