Should you build or buy Presales Management?
Presales management software tracks technical sales engagements: SE assignment, proof-of-concept plans, technical-win criteria, and cross-deal analytics on where sales engineers spend time. Sales engineering and solutions consulting teams use it alongside their CRM to prove technical fit and report presales impact on revenue to leadership.
Start with custom objects in your CRM for SE intake, POC plans and technical-win criteria; buy a demo-automation product only when repeatable demos consume SE capacity you can measure, and treat AI seller-agent bundles as separate purchases to evaluate on their own evidence.
Build it, buy it, or bridge?
When building makes sense
Presales tracking is genuinely buildable in the CRM you already own. A RevOps design pattern for a Technical Validation object, with win criteria, contacts, and recap fields attached to the opportunity, covers most of what a dedicated presales platform tracks, and SE teams run this in production on Salesforce custom objects and spreadsheets. Homerun Presales itself started as a tool one of its founders built for his own presales work before it was commercialized, which is a reasonable signal that the tracking layer alone doesn't require a vendor relationship. What building doesn't solve is demo automation: the tooling that lets an SE spin up a tailored, interactive demo without a live screen-share, and the cross-deal analytics that turn raw activity data into a defensible story about presales impact on revenue. Build the tracking layer freely. Treat demo automation as a separate decision with its own evidence bar.
When buying makes sense
Buy demo automation only once repeatable, overview-level demos are a measured drain on SE capacity, not before. Walnut prices at $575 a month for its Ignite tier and $1,550 for Accelerate, both billed annually, and positions itself around AI-assisted demo drafting and interactive Playlists rather than replacing your CRM's deal tracking. Vendor-published cases lean toward hard numbers here: Unanet reported a 30 percent cut in live demos and one SE's worth of recovered capacity after adopting Consensus, Esker reported its win rate roughly doubling alongside a 60 percent gain in presales capacity, and G&A Partners reported adding 25 percent SE capacity while cutting required live intro demos in half. Reprise and Consensus don't publish list pricing, but their median contracts, per Vendr's transaction data, land in a broadly similar range to Walnut's three-year cost. Vivun has moved differently, repositioning around Hero, an AI seller-teammate product, which is worth evaluating on its own evidence rather than assuming it's a like-for-like swap for demo automation. Buy when demo volume, not deal tracking, is the actual constraint on your SE team's time.

Frequently asked
Do sales engineering teams need dedicated presales software, or does CRM tracking suffice?
For tracking technical-win criteria, POC plans, and SE activity, CRM custom objects genuinely suffice, and teams run this in production on Salesforce and HubSpot without a separate platform. Dedicated presales software earns its cost specifically for demo automation and cross-deal analytics, not for the tracking function itself.
What measurable impact do demo automation tools actually have?
Vendor-published cases report concrete numbers: Unanet cited a 30 percent reduction in live demos and about one SE's worth of recovered capacity after adopting Consensus. Whether that generalizes to your team depends on how much SE time currently goes to repeatable overview demos versus custom technical work.
What is Vivun's Hero, and is it the same thing as demo automation?
Hero is Vivun's repositioning around an AI seller-teammate product, distinct from tools like Walnut or Consensus that automate the demo itself. Evaluate it on its own evidence rather than treating it as a substitute for demo automation, since the two solve different problems.
