Alternatives to Saleo?

Hi all! Currently looking at Saleo as our demo environment is becoming quite complex and I have Devs, CSMs, Product Marketing etc all sharing it with our BDMs, plus we have an intern inputting data manually on a weekly basis to provide a realistic demo. Archaic, I know.

I've looked at Saleo and it ticks every single box, but the pricing is prohibitive for us at 40k+. Our sales tech stack is Salesforce+Salesloft. Are there any similar solutions to saleo for a much lower price? We don't need the Walnut aspect of the solution, only the 'fake data' element. We're looking to pay 5-10k pa for around 6 seats.

Thank you all!
