Paris-based Sillage raises €1.7 million to help sales teams follow the right signals

Sillage, a French go-to-market AI startup helping enterprise sales teams turn buying signals into qualified pipeline, has announced its official launch alongside a €1.7 million ($2 million) pre-Seed round.

The round included Kima Ventures, Angel Invest, and Drysdale Ventures, alongside a wider group of angels and investors. With the fresh funding, Sillage aims to continue developing its platform for go-to-market teams, helping them detect buying intent through real-time social, hiring, competitor, and account signals.

Arthur Coudouy, co-founder of Sillage, said in a public statement: “At Sillage, we believe AI should support your sales reps, not replace them. We thrive on helping our customers close enterprise deals, something no AI SDR could do. When customer relationships are at the core of your sales motion, you don’t want AI handling conversations, you want it as a copilot.”

There are several relevant 2026 funding rounds in the wider European go-to-market and sales AI space, that help contextualise Sillage and its funding.

• Stockholm-based Agaton raised €8.4 million in Seed funding to turn customer conversations into revenue intelligence and accelerate go-to-market and product development
• Berlin-based Zell raised €500k to automate sales management workflows and support European expansion
• Helsinki-based Realm raised €3.8 million in Seed funding to bring AI agents into enterprise sales and speed up sales cycles
• Vilnius-based Outcraft AI raised €2 million in pre-Seed funding to build autonomous revenue agents for real-time customer engagement
• Warsaw-based Zynt secured €424.4k in pre-Seed funding to advance its B2B signal intelligence platform and prepare for enterprise clients.

Taken together, these rounds represent approximately €15 million in funding across adjacent sales intelligence, go-to-market automation, revenue operations and AI-agent categories.

Sillage’s launch therefore fits into a broader European funding pattern around AI tools that aim to improve sales prioritisation, workflow execution and customer engagement.

Arnaud Weiss, co-founder of Sillage, noted: “Our vision of AI for go-to-market is simple: make the job more interesting, and more productive. Sillage agents do exactly that: surface buying signals to engage your top accounts with context. Fewer actions, more results. Quality over quantity.”

Founded in 2025, Sillage is building a signal engine for sales teams, designed to help reps engage target accounts at the right time, with the right message, without replacing the human relationships at the centre of enterprise selling.

Sillage’s approach is built around the idea that prospecting should not mean flooding people with AI-generated spam. The company argues that human relationships run on reciprocity, and that outreach only works when sales teams put in the effort to understand who they are contacting, why now is the right moment, and what context matters most.

The startup’s product surfaces buying signals that help sales teams prioritise accounts and approach them with relevant context.

These signals include moments such as a past champion joining a new company, a prospect engaging with a competitor, or a pain point being expressed publicly. Sillage says these insights can help teams run warmer outbound strategies, protect key accounts, and identify opportunities to build more pipeline.

According to the company, early customers have seen reply rates increase by more than 50% compared with regular outbound. Sillage has built the product alongside companies including Yoobic, Salesforce, FullEnrich, Figures, and Sopht, and says the platform is now publicly available.

Sillage is positioning itself against a growing wave of AI sales tools focused on automation and replacement. Rather than aiming to remove sales reps from the process, the company wants to give them more timely information and practical context so they can act with precision instead of volume.

Its platform is intended to support account-based marketing and lead generation by helping teams detect buying intent before competitors do.

German Super Angel fund and investor in the round; Angel Invest, shared: “GenAI is commoditizing software fast. In that world, the only durable moats left are brand and sales execution. We believe the next wave of B2B winners won’t be decided by who has the best product – but by who can engage the right accounts, at the right moment, with the right context.”

Sillage’s platform works by allowing teams to define their ideal customer profile, activate signal agents, and receive qualified leads through their existing workflows. The company says the product can be set up in five minutes, works inside Slack and CRM systems, and can also feed AI agents.

Its agents aggregate first-party, social, and web signals across enterprise accounts, including competitor alerts, champion tracking, power map moves, subsidiary mapping, keyword mentions, and funding rounds.

The company says its product can support sales teams across three core areas:

• Building more pipeline: Sillage surfaces buying intent when it appears and gives reps openers ready to send.
• Closing more deals: It provides live account context, competitor engagement alerts, and suggested next steps.
• Securing or upselling existing customers: It helps teams track key moves inside customer accounts and identify upsell signals when they surface.

Sillage’s launch comes as many sales teams are rethinking outbound strategies in response to the rise of generative AI. While automation has made it easier to scale outreach, the company argues that better sales execution depends on quality rather than quantity.
