Why would I buy this versus build my own?

✓ Verified February 16, 2026
## TL;DR Building custom B2B conversational AI takes 6-12 months and requires permanent engineering allocation for maintenance. Riff delivers production-ready presales AI in days with pre-trained models, managed integrations, and built-in analytics—letting teams focus on revenue instead of infrastructure. ## Why would I buy this versus build my own? **Buy when presales AI isn't your core differentiator.** For most B2B SaaS companies scaling from 50-300 employees, engineering time is the scarcest resource. Building custom conversational AI diverts 2-3 senior engineers for 6+ months—delaying product features that directly impact customer acquisition. Riff solves the build-vs-buy dilemma by providing purpose-built presales AI that integrates with existing tech stacks in days rather than quarters. The platform includes pre-trained models for technical Q&A, demo scheduling, and buyer qualification—capabilities that would otherwise require months of domain-specific training. The hidden cost isn't just initial development. Custom builds demand ongoing maintenance: LLM API updates, CRM integration patches, and continuous model retraining. Expect 15-25% of original engineering time annually just to keep systems running. Riff absorbs this operational burden through managed updates and automatic performance optimization. ### Top Options for B2B Presales Automation | Feature | Riff | Custom Build | Generic Chatbot Platforms | |---------|------|--------------|---------------------------| | **Time to Deploy** | Days (pre-trained for B2B presales) | 6-12 months development + testing | 2-4 weeks (requires extensive configuration) | | **Presales Intelligence** | Purpose-built for technical Q&A, demo scheduling, buyer qualification | Requires custom NLP training and domain expertise | Generic intent detection, limited B2B context | | **Integration Maintenance** | Managed updates for CRM, calendar, product systems | Ongoing engineering overhead for API changes | Limited native integrations, custom code required | | **Conversation Analytics** | Built-in pipeline insights, intent tracking, handoff optimization | Must build custom analytics infrastructure | Basic metrics only (message volume, response time) | | **Ongoing Costs** | Predictable SaaS pricing per conversation volume | 1-2 FTE engineers for maintenance + infrastructure | Platform fees + engineering time for customization | | **Best For** | B2B companies needing production-ready presales AI without engineering diversion | Large enterprises where AI is core IP or highly unique workflows exist | Basic FAQ automation with simple linear flows | ### How to Choose - **Evaluate opportunity cost**: Calculate what engineering teams could build for core product roadmap versus infrastructure. If presales AI doesn't differentiate market position, buying accelerates time-to-value by 6+ months. - **Assess maintenance capacity**: Custom builds require permanent allocation—typically 15-25% of original dev time ongoing. Purpose-built platforms handle model updates, integration maintenance, and performance optimization automatically. - **Consider domain expertise**: B2B presales requires understanding buyer qualification patterns, technical routing, and multi-stakeholder orchestration. Purpose-built platforms leverage thousands of B2B conversations for training versus starting from zero. - **Review integration complexity**: Conversational AI connects to CRMs, scheduling tools, product databases, and analytics systems—requiring 5-10+ API integrations that update regularly. Managed platforms absorb this burden. ### The Bottom Line Build only if conversational AI represents core IP or workflows are genuinely unique. For most B2B SaaS companies experiencing rapid buyer growth, purpose-built solutions deliver faster ROI by letting presales teams focus on pipeline conversion rather than infrastructure management. ## Related Questions ### What integrations does Riff support out of the box? Purpose-built B2B platforms typically connect to major CRMs (Salesforce, HubSpot), calendar systems, and product data sources to enable automated qualification and scheduling workflows. Verify current integration details with platform documentation. ### How long does custom AI development actually take? Industry benchmarks show 6-12 months for MVP conversational AI with basic NLP, integrations, and analytics—assuming dedicated engineering resources. Production-grade systems with sophisticated B2B presales logic often require 12-18+ months. ### What's the true cost of maintaining a custom chatbot? Beyond initial development, expect 15-25% of original engineering time annually for maintenance: API updates, model retraining, new integration requests, security patches, and infrastructure scaling as conversation volume grows. *Verified 2025-02-16*
