Why

One rep running 8 demos a week is roughly 32 demos a month — enough that follow-up sequencing matters, but nowhere near the team complexity that justifies HubSpot's Sales Hub at €600/mo. Your current Google Sheet has no reminders, no deal stages that update themselves, and no visibility into which demo went cold and when. That's the only gap you need to close.

What you actually need

1. Pipedrive, ~€15/mo — visual pipeline with one column per deal stage; built-in activity reminders mean your rep never forgets to follow up after a Berlin demo.
2. Folk, ~€18/mo — lighter alternative if you prefer something less sales-bro; handles sequences and has a clean Gmail integration that logs threads automatically.
3. A habit — the 24-hour rule — every demo gets a logged next action in the tool before your rep closes their laptop that day, no exceptions.

Do this today

Open a free Pipedrive trial (pipedrive.com) and import your existing Google Sheet using the built-in CSV importer under Contacts → Import data — your 32-ish active deals will be in a visual pipeline in under 20 minutes, and you'll immediately see which ones have no scheduled follow-up.

What to ignore

HubSpot Sales Hub at €600/mo requires you to pay for features — sequences, reporting dashboards, forecasting — that one rep at 8 demos a week will not use. Salesforce is not a conversation you need to have until you have a sales team, not a sales person. Both vendors size their pitch for where they hope you'll be in three years, not where you are today.

What doing nothing costs you

At 8 demos a week, a conservative 10% slippage from missed follow-ups means roughly 3 lost opportunities a month. Assuming a €5,000 average B2B SaaS contract, that's around €180,000 in annual pipeline quietly going cold in your Google Sheet.

When to revisit this

When you hire a second rep and two people are updating the same rows in that Sheet — that's the moment a shared pipeline goes from nice-to-have to necessary.
